670 Nanometers

The only thing more beautiful than a sunset is the sunrise and even then they split the title pretty evenly down the line.

When I try and compare the most beautiful sunrise I've ever seen to the most beautiful sunset I've ever seen—it's almost as if the two are mirror images of one another.

To date, The most beautiful sunset sky I have ever seen was in North Hollywood, California.

It was 2009, around the same date as Michael Jackson's funeral. It may have been the same day. It may even have been the reason why that sunset was so spectacular, But then I saw several more like it, after it.

Not that they made the first one least impressive, Only that it made it a little less rare than I thought, Which waa fine because it meant I could get it anytime I really needed it. I saw sunsets that were more intense in color, after the first sunset. I saw other sunsets that were more intense in the structures to it they sometimes seemed to have— as if painted across the darkening night sky.

The vibrant colors out on the West Coast were flawed tho. They were also reals signs of toxic pollution in the air. A remarkable reminder that beauty comes with its price..

If you made it this far you came for the most beautiful sunrise I have ever seen, that would be the day my son was born and my life felt as if it started over.

That is by far the most beautiful sunrise I have ever awoken in.

Besides that, The most beautiful sunrise I have ever seen was in Montauk November 2022. I was covered in red light at the edge of the ocean. engulfed in so much red light that you can't imagine it no matter how hard you try or how creative your mind can be.

Early morning red light does not last long. It is the light that occurs before the daylight begins to break and the sun's yellow rays flash across the sky lighting up its blue color into morning.

I now get that red light near my home in the mornings. Never as engulfed as out east at the edge of the ocean, But strong enough to penetrate any exposed areas to help heal organs to.

Sunbathing has been prescribed as a treatment for various ailments for many millennia.

Still, Only because the early morning red light seems to have more healing powers than the sunset's red light is why I can honestly say that the only thing more beautiful than the most beautiful sunset sky is the most beautiful sunrise sky.

You are my sunrise.

How Long to Do Red Light Therapy on the Scalp: Best Practices and Tips

Red light therapy has gained popularity as a natural, non-invasive method to improve hair health and stimulate hair growth. By directing specific wavelengths of red light to the scalp, red light therapy promotes cell repair, improves circulation, and supports hair follicle health. But, when it comes to achieving optimal results, how long should each session last? Here, we’ll explore recommended times for red light therapy on the scalp, key factors that influence session duration, and practical tips for success.

What Is Red Light Therapy for Hair Growth?

Red light therapy, also known as low-level laser therapy (LLLT), uses low-power red or near-infrared light to stimulate cell activity. When applied to the scalp, it can penetrate the skin’s layers and encourage hair follicles to become more active, promoting hair growth and thickness. Red light therapy is safe, non-invasive, and painless, making it an appealing choice for those looking to support natural hair health.

How Long Should You Use Red Light Therapy on the Scalp?

The typical recommended duration for red light therapy sessions on the scalp is 10 to 20 minutes per session, performed 2 to 3 times a week. However, the exact timing can vary based on several factors, including device intensity, wavelength, and individual needs.

1. Type of Device and Power Level

Red light therapy devices come in a range of power levels and designs, from handheld devices to caps and panels. Higher-power devices typically require shorter sessions (10–15 minutes), while lower-power devices may need up to 20 minutes per session for optimal effect.

2. Session Frequency

2 to 3 sessions per week is generally sufficient to see benefits without overusing. Consistent application gives hair follicles time to respond and strengthens hair over time.

3. Wavelength of the Light

The ideal wavelength for red light therapy ranges from 630 to 670 nanometers. Light within this range can penetrate the scalp and effectively reach hair follicles, ensuring maximum benefit. Devices with these specifications are more likely to yield results in shorter, regular sessions.

4. Individual Hair and Scalp Condition

If you’re dealing with significant hair thinning, you may benefit from slightly longer sessions within the recommended range. However, it’s important to follow device guidelines and consult a professional if you’re unsure to avoid overexposure.

Follow a Regular Schedule: Set aside specific days for red light therapy to establish a routine. The benefits accumulate over time, and consistency is key to seeing improvement.

Monitor Scalp Sensitivity: If you notice any redness or discomfort, consider reducing session length or frequency. While red light therapy is safe, everyone’s skin sensitivity is different.

Combine with Other Hair Care Practices: For best results, pair red light therapy with a healthy scalp care routine, including gentle shampoos and scalp massages.

Stay Hydrated: Hydration plays a role in skin health. Drinking enough water supports your body’s ability to repair cells, which can enhance the results of red light therapy.

Common Questions about Red Light Therapy on the Scalp

1. Can I Use Red Light Therapy on the Scalp Every Day?

Using red light therapy 2 to 3 times a week is generally sufficient. Daily sessions are not typically necessary and may lead to mild scalp sensitivity.

2. How Long Does It Take to See Results?

Most users start to notice improvements within 3 to 6 months of regular use. Hair growth is a gradual process, and patience is essential for seeing full results.

3. What’s the Best Device for Scalp Therapy?

Choose a device that offers a wavelength range between 630 and 670 nanometers and is designed specifically for scalp use. Caps or panels tend to cover larger areas and may be more efficient than handheld devices.

4. Does Red Light Therapy Work for All Hair Types?

Yes, red light therapy is effective for various hair types and textures. However, individual results can vary based on genetics, scalp health, and lifestyle factors.

5. Are There Any Side Effects?

Red light therapy is generally considered safe, with minimal risk of side effects. Mild scalp redness or warmth may occur but usually subsides shortly after the session.

Conclusion

Red light therapy is an effective, non-invasive way to promote scalp health and hair growth. By following the recommended session duration of 10 to 20 minutes, 2 to 3 times a week, you can achieve noticeable improvements over time. Staying consistent, using a high-quality device, and pairing the therapy with healthy hair practices can help maximize results. Remember, patience and routine are essential, as red light therapy works gradually to support fuller, healthier hair.

TAFAKKUR: Part 161

More than a Glow: The Firefly

"One night, a very lonely firefly goes off in search of friends. Each time he sees a flicker of light he flies off toward it, but none of them turn out to be fireflies. He sees a lantern, an owl's eyes, even headlights shining in the darkness. Will the lonely firefly ever find creatures like himself?"

You need to read "The Very Lonely Firefly," a story book delighting children of all ages by Eric Carle to get the answer. In the mean time, you can read this article to have better insight into the enchanting world of the firefly. Are they just a pleasure to our eyes, during their short lives in the summer, or do they live on in children's books?

Fireflies, or lightning bugs, belong to the Lampyridae family. There are thousands of firefly species all over the world and none of them are actually flies. Then what are they? Well, they are beetles, who get the names "firefly" and "lightning bug" because of the flashes of light emanating from their bodies, a process called bioluminescence. This "cold light" does not heat up or burn its producer through infrared or ultraviolet frequencies, and is formed by the action of an enzyme called luciferase in the lower abdomen of the firefly. It may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometers. The enzyme luciferase acts on the luciferin, in the presence of magnesium ions, ATP, and oxygen to produce light. According to Vieira et al., 2012, in the Journal of Photochemistry and Photobiology, the firefly's luciferase is the most important and studied bioluminescence system in scientific research. The firefly luciferase was cloned and isolated for the purpose of constructing bioassay systems in the late 1980s. Since then, due to very interesting characteristics, this system has been used in numerous biomedical, pharmaceutical and bioanalytical applications.

In biomedical research, the ability to visualize a biological process is very important because it offers the most direct method to support or disprove any scientific claim. Therefore, firefly luciferase is very desirable as a reporter in this area. Typically, the luciferase gene is cloned with a DNA sequence of interest into cells and then the cells are assayed by measuring its bioluminescence. Fusing a protein with luciferase is like putting a reflective vest on a cyclist in the dark to be able to watch him. Because the firefly luciferase lights up, it helps screening for chemical biology and drug discovery applications in academia and the pharmaceutical industry. For example, the firefly luciferase gene was used as a reporter to screen tumor-specific promoters in lung cancer. Another example showing how beneficial the firefly is for scientific research is a rapid in vivo (Latin for within the living) assessment of drug efficacy against Mycobacterium tuberculosis, which is the causative agent of most cases of tuberculosis, using an improved firefly luciferase. In this study, Andreu et al., 2013, used a Mycobacterium tuberculosis strain carrying a red-shifted derivative of the firefly luciferase gene to infect mice, and they monitored disease progression in living animals by bioluminescence imaging before and after treatment with a frontline anti-tuberculosis drug. Furthermore, firefly luciferase was used in a research about anti-malaria drugs, an illness which affects about 5% of the world's population and brings a death toll of 0.5–2.5 million each year.

Firefly luciferase is not only used in biomedical research, but also in molecular plant biology. In the early '90s, plant scientists were already able to show the bioluminescence of a promoter fragment fused to the firefly luciferase gene and its regulation by phytochrome (a pigment that plants use to detect light) and the circadian clock (a roughly 24 hour cycle in the physiological processes of living beings) (10) in plants. Some examples for the great usage of this system among many others include a firefly luciferase complementation assay that was used to reveal the interacting partners of Open Stomata 1 protein, which is critical for plant drought responses in Brassica oleracea (cabbage) (11) and the characterization of the promoter region of an important gene encoding a copper chaperone for the copper/zinc superoxide dismutase that is involved in oxidative stress protection of the potato plant.

Scientists have found many ways to use the firefly light, but what is the function of it for its real owner? Marc Branham, an assistant professor in the department of entomology and nematology at the University of Florida, explains. "Fireflies seem to flash light for a variety of reasons. The larvae produce short glows and are primarily active at night, even though many species are subterranean (underground) or semi-aquatic. Fireflies produce defensive steroids in their bodies that make them unpalatable to predators. Larvae use their glows as warning displays to communicate their distastefulness. As adults, many fireflies have flash patterns distinctive to their species and use them to identify other members of their species as well as to discriminate between members of the opposite sex. Several studies have shown that female fireflies choose mates depending upon specific male flash pattern characteristics. Higher male flash rates, as well as increased flash intensity, have been shown to be more attractive to females in two different firefly species."

Are there other creatures like fireflies producing light? "Besides fireflies, many other organisms, especially marine creatures, use bioluminescence for sexual selection, attracting prey and as a means of camouflage, and it has been estimated that about 90 percent of deep-sea animals are bioluminescent, according to the Scripps Institution of Oceanography," says Remy Melina, a staff writer for "Life's Little Mysteries."

A firefly's glow is a theme of summer nights, romantic poems, and childhood adventures and books. However, when you enjoy a firework show done by fireflies next time, please look at them more carefully by thinking that they have more than that to offer humanity, including thrilling scientific inventions done with just a single protein from them. Who knows what else they have waiting to be discovered by us? How amazing it is that, like everything else created on earth, a firefly is also a very precious art piece decorated with intricate features, and even though it is very tiny, its service to humanity is, in many ways, enormous.

These are long exposure photos of fireflies in Okayama prefecture, Japan.

Fireflies or Lampyridae, are a family of insects within the order Coleoptera, aka; the Beetle family. Firlies exist on every continent in the world, except Antarctica, with about 2,000 species globally. With the exception of certain species which are active during the day, fireflies are bioluminescent organisms, which means that they produce their own light. Fireflies produce their “light” through a chemical reaction consisting the substrate Luciferin, the enzyme Luciferase, Adenosine Triphosphate (ATP) and oxygen. This chemically produced light may be yellow, green or pale red with wavelengths ranging from 510 to 670 nanometers. The colour of light emitted, signal pattern, time and duration vary from species to species. In some of these species, all stages of the lifecycle glow, even the larvae, which are called “glow-worms”.

Fireflies produce light for three primary reasons; the males use the light to signal females for the purpose of mating, the light is used as a mechanism of defense against predators (the light warns other species that they are distasteful), and finally, the light can be used as a mechanism to warn others of danger.

Whatever the reason for creating this beautiful light, it definitely makes them a captivating sight on summer nights.

About 2,100 species of fireflies are found in temperate and tropical climates. Many are in marshes or in wet, wooded areas where their larvae have abundant sources of food. Their larvae emit light and often are called "glowworms" in Eurasia and elsewhere. In the Americas, "glow worm" also refers to the related Phengodidae. In New Zealand and Australia the term "glow worm" is in use for the luminescent larvae of the fungus gnat Arachnocampa.”

Age-related vision decline reversed with simple therapy

#thedawn📉 👩‍🔬 👓 🔆 📘 🔍 🌇 *⃣

Colorado News

Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new UCL-led study, the first of its kind in humans.

Scientists believe the discovery, published in the Journals of Gerontology, could signal the dawn of new affordable home-based eye therapies, helping the millions of people globally with naturally declining vision.

In the UK there are currently around 12 million people aged over 65: in 50 years this will increase to around 20 million and all will have some degree of visual decline because of retinal ageing.

Lead author, Professor Glen Jeffery (UCL Institute of Ophthalmology) said: “As you age your visual system declines significantly, particularly once over 40.

“Your retinal sensitivity and your colour vision are both gradually undermined, and with an ageing population, this is an increasingly important issue.

“To try to stem or reverse this decline, we sought to reboot the retina’s ageing cells with short bursts of longwave light.”

In humans, around 40 years-old, cells in the eye’s retina begin to age, and the pace of this ageing is caused, in part, when the cell’s mitochondria, whose role is to produce energy (known as ATP) and boost cell function, also start to decline.

amzn_assoc_tracking_id = "northdenver01-20"; amzn_assoc_ad_mode = "manual"; amzn_assoc_ad_type = "smart"; amzn_assoc_marketplace = "amazon"; amzn_assoc_region = "US"; amzn_assoc_design = "enhanced_links"; amzn_assoc_asins = "B0845LVD7L"; amzn_assoc_placement = "adunit"; amzn_assoc_linkid = "97e78353bf8dec2afc5893a7b54376e7"; Mitochondrial density is greatest in the retina’s photoreceptor cells, which have high energy demands. As a result, the retina ages faster than other organs, with a 70% ATP reduction over life, causing a significant decline in photoreceptor function as they lack the energy to perform their normal role. Researchers built on their previous findings in mice, bumblebees and fruit flies, which all found significant improvements in the function of the retina’s photoreceptors when their eyes were exposed to 670 nanometer (long wavelength) deep red light. “Mitochondria have specific light absorbance characteristics influencing their performance: longer wavelengths spanning 650 to 1000nm are absorbed and improve mitochondrial performance to increase energy production,” said Professor Jeffery.

The retina’s photoreceptor population is formed of cones, which mediate colour vision and rods, which provide peripheral vision and adapt vision in low/dim light.

For the study, 24 people (12 male, 12 female), aged between 28 and 72, who had no ocular disease, were recruited. All participants’ eyes were tested for the sensitivity of their rods and cones at the start of the study. Rod sensitivity was measured in dark adapted eyes (with pupils dilated) by asking participants to detect dim light signals in the dark, and cone function was tested by subjects identifying coloured letters that had very low contrast and appeared increasingly blurred, a process called colour contrast.

All participants were then given a small LED torch* to take home and were asked to look into** its deep red 670nm light beam for three minutes a day for two weeks. They were then re-tested for their rod and cone sensitivity

Results

Researchers found the 670nm light had no impact in younger individuals, but in those around 40 years and over, significant improvements were obtained. Cone colour contrast sensitivity (the ability to detect colours) improved by up to 20% in some people aged around 40 and over. Improvements were more significant in the blue part of the colour spectrum that is more vulnerable in ageing.

Rod sensitivity (the ability to see in low light) also improved significantly in those aged around 40 and over, though less than colour contrast.

Professor Jeffery said: “Our study shows that it is possible to significantly improve vision that has declined in aged individuals using simple brief exposures to light wavelengths that recharge the energy system that has declined in the retina cells, rather like re-charging a battery. “The technology is simple and very safe, using a deep red light of a specific wavelength, that is absorbed by mitochondria in the retina that supply energy for cellular function.

“Our devices cost about $25 to make, so the technology is highly accessible to members of the public.”

This research was funded by the Biotechnology and Biological Sciences Research Council.

👁 Red light improves vision

With age, the vision of us all deteriorates. The retina, where light is transformed into visual impressions, ages faster than other organs in the body, starting around the age of 40. Now it turns out that there is a simple and inexpensive solution to counteract this deterioration of vision. By staring into a red light for three minutes a day, impaired vision can not only be stopped, but an already impaired visual ability can be reversed and improved.Red light at wavelengths between 650 and 1000 nanometers, deep red in color, has already been shown to strengthen the function of the mitochondria. The mitochondria in our cells are responsible, among other things, for producing the substance adenosine triphosphate , which supplies rods and drops in our eyes with energy. This production decreases over the years, with the help of the deep red light, the production can return to previous levels and thus strengthen the vision."The technology is both simple and safe, by using red light at specific wavelengths that are absorbed by the cells' mitochondria in the retina, which give energy to the function of the cells. Our equipment costs about £ 12 (about $ 140) to make, so it's easily accessible to the public," says Professor Glen Jeffrey of the UCL Institute of Ophthalmology , lead author of the article.The study was conducted on 24 subjects between the ages of 28 and 72. These were each given a LED light with a wavelength of 670 nm which they would look into for three minutes a day. Read the full article

Perhaps it was this Men's Health magazine article, in which I discuss a form of light therapy called “photobiomodulation” as a way for guys to increase sexual performance, sperm count and testosterone.

Or perhaps it's because I've described on multiple podcasts how I pull down my pants for 20-30 minutes a day while I'm at my desk, and “bathe my balls” in red and near-infrared light, using a device called a “Joovv”.

Turns out the benefits of photobiomodulation go far beyond your nether regions. Heck, this recent study even hinted at the fact that perhaps it should actually be banned as an illegal performance-enhancing drug!

On today's podcast, I discuss photobiomodulation ins and outs with two experts in the field: Justin Strahan and Scott Nelson.

Not just any man can take his wife's dream and make it a reality. This is just one of the reasons why Justin is so special. Justin's affinity for process and extreme attention to detail is why we are lucky to have him as head of R&D. The two words we would to describe Justin are intuitive and thorough. Prior to inventing and developing the Joovv, he spent his career as an engineer managing design and development teams. He also has six children, and can apparently play drums and trumpet like it's nobody's business.

Scott is the impetus, power, and energy that set Joovv in motion. As head of commercialization, his ability to metabolize information quickly makes him an irreplaceable asset. The two words we would use to describe Scott are efficient and personable. Prior to cofounding Joovv, he spent his entire professional career in leadership positions with some of the largest medical device companies in the world, including Medtronic, Covidien, Boston Scientific, and C.R. Bard.

During our discussion, you'll discover:

-The intriguing history of photobiomodulation (PBM) and the JOOVV light…11:11

All types of health benefits from a wide range of wavelengths.

Sunlight is optimal

Red (600-670 nanometers); near infrared (800-880 nanometers)

Visible Red light is considered near infrared.

Far infrared is useful for heating tissue (over 3000 nanometers); you can't see it.

Comparing research between red and near-infrared light.

 Original PBM devices were lasers. Low-level laser therapy (LLLT)

Difference between LED and lasers: light source itself. Laser is a specific wavelength. LED is tight range, but not a coherent beam.

Photo medicine is still a niche field. Most older academics say that it's based on laser therapy, younger professionals say with newer LED light, you can deliver the same level of intensity over a much broader treatment area.

How is LED light different from sunlight?

Americans spend around 93% of their lifetime indoors due to their work and lifestyle.

PBM harnesses specific wavelengths; restores healthy function to offset stressors such as wifi, bluetooth, etc.

It's similar to supplementing our diets with a smoothie or multivitamin.

It doesn't contain the UVA or UVB, blue light, etc.

-The compelling research behind phototherapy for everything from testosterone to collagen to thyroid to muscular recovery and beyond…21:00

 Wide-ranging benefits: skin health, muscle recovery, thyroid function.

Supported by over 3,000 peer-reviewed manuscripts.

Over 200 placebo-controlled trials.

Restores natural skin health.

Red light is studied for skin health; near infrared often used for joint pain studies.

Are JOOVV lights effective for controlling acne?

The effect of red lights on the eyes. Will it damage your eyes to stare at a JOOVV, or will it even help them?

Proven to help degenerative eyes.

Near-infrared a bit more comfortable to the eye.

Begin treatment with eyes closed; then open eyes if you feel comfortable.

JOOVV elite allows you to use only near-infrared light.

JOOVV devices are registered with the FDA, Class 2.

How red and infrared light affects collagen production.

It increases collagen production, helps restore joint health.

Copper and green light have been shown to enhance benefits of light therapy.

Can PBM mitigate circadian rhythm or exposure to artificial light?

Sun gets a “bad rap”; unfairly associated with skin cancer.

Studies prove that red/infrared light increase levels of melatonin.

-Is PBM effective in attaining weight loss?…41:30

Not necessarily weight loss, but there is a “slimming effect”.

Some studies have shown that red light helps in increasing metabolism.

Red light has been shown to mitigate the effects of sleep deprivation. 

-Why PBM is now under consideration for classification as a “performance enhancing drug”…46:30

Meta-analysis claimed that red light builds up muscle tissue.

Near-infrared waves have had a profound impact.

-How PBM affects stem cells…49:30

-The effect of using PBM on your neck for thyroid issues…51:30

-The optimal amount of PBM to which you should expose yourself per day…54:23

It's difficult to test the power output of a device.

There are many variables that affect the amount of PBM a device is able to put out.

Ensure you purchase your device from a reliable, trusted company.

JOOVV is ~100 milowatts per sq. cm.

Recommended 10-minute treatment about 6″ away from the device.

-The differences and benefits of continuous wave vs pulsed frequencies…1:01:20

Pulsed means the light turns on and off very rapidly.

A bit of ambiguity on the results of pulsed; continuous wave is tried and true.

Sunlight is considered to be a continuous wave light.

-Whether the JOOVV produces much EMF or flicker, and if you can actually look at the light without eye damage…1:03:07

Household LED lighting is different from PBM. JOOVV lights have AC/DC built in.

JOOVV lights mitigate “dirty electricity.” 

Newer devices are even more effective.

-What kind of things you can combine with photobiomodulation to enhance the effects…1:10:30

-And much more!

Vevazz Led: An Option For Safe, Effective Fat Loss

Many professionals consider using Vevazz LED beds for non-surgical weight loss methodology. This form of non surgical liposuction popularized these apparatus as well as the large number of research studies encouraging their usage. These studies have demonstrated that introducing laser light to subcutaneous fat from the body is beneficial and produces positive results. The light might have to be high and utilize non wave lengths.

In place, the laser-based (non surgical) liposuction procedure yields similar effects as traditional invasive (surgical) liposuction. This Vevazz lasers targets non invasive laser emissions to targeted portions of the human body. The vitality liquefies the fat (adipose residue). From the parts of the body at which the layers of fat remains thin, like the neck, the liquefied fat is absorbed by your human body and later expunged naturally. In different areas, the fat gets eliminated via cannula, which might be thin tubes inside the human anatomy. A significant portion of this fat eradicated by the process is that portion of their fat that's resistant to exercises and dietary methods.

The human body can adjust itself prior to the vulnerability into the lipo lasers, once the body temperature increases. Afterwards, the wavelength decreases between 635 and 670 nanometers to empty fat. Your system is naturally equipped with a lymph system that helps remove the waste. Fat reduction does occur when the copious levels of essential fatty acids have evacuated.

Lipo Laser/LED Machines  - Overview of Key Constituents

The main section of heat production mechanism that the machines is assembled up on (and so, its effectiveness) would be the laser-generating diodes. The quality of lipo laser devices profoundly depends upon the diodes because they produce the ability - that the heat that could finally eliminate the fat. Diodes generate emissions, that includes a specific wavelength that the machine depends up on for optimal energy. The number of diodes present is exactly that which creates fluence; that is the way we can determine brightness and also how much of the human anatomy is able to be covered.

Lipo laser components each have lots of pads, also referred to as paddles. Machines could have 4 to 24 paddles, depending upon the brand and model. The patient's body will likely probably be strapped with those light, comfy paddles. Usually the straps are constructed of Velcro or elastic. A client may possibly lay down about the paddles and also have them paired.

The amount of diodes in each paddle fluctuates. The 2nd generation produced 650-660 nm wave lengths. Now's generation, that will be known as the third creation, produces wavelengths ranging 635 into 640 nm. The younger the production, the stronger its own power. That is why modern production machines are more preferred by the clinic-owners.

The power of diodes has grown through recent years. In each production, the number of milliwatts per diode has risen. The very first production lipo lasers used 510 milliwatt diodes, second generation diodes used 10-20 milliwatts, and third generation diodes contain 20 to 40 milliwatts. Evidently, this can be a enormous rise during these time periods. Now, patients are more powerful than ever .

The strength of a lipo laser model is never determined by the range of diodes. It's not possible to put a couple of diodes containing high wave-lengths with each other to produce up one exceptionally potent diode. Shorter wavelengths are far more potent and much more efficient than wavelengths. Shorter wavelengths penetrate the body more efficiently, which is why it is preferred over longer wave lengths.

How Cold Laser Therapy in London Works on Acne Clearance?

Acne is a multifactorial disease that affects the pilosebaceous unit in structure and function. It occurs in adolescents and is suffered worldwide. In the most severe cases, it can involve the family group in its emotional and economic sphere. Acne Clearance Cold Laser Therapy in London has been used as an alternative medical procedure option for the treatment of this disease; due to its antibacterial, anti-oedematous and immune system stimulating action.

How Does Cold Laser Therapy In London Work?

During this procedure, different wavelengths and low-level light outputs are applied directly to a target area. Body tissue absorbs light. Usually, red and near-infrared light give rise to reaction, and damaged cells respond with a physiological reaction that promotes regeneration.

Surface tissue is reacted with wavelengths from 600 to 700 nanometers (nm) and in extensive penetration the wavelengths from 780 to 950 nm are used.

Although you will feel the laser device touch your skin, the procedure is painless and non-invasive. There will be no sound, and you will not feel vibrations or heat. Each treatment generally takes only a few minutes.

How Low-Level Laser Therapy in London Works on Skin?

Skin Rejuvenation                                                                  

Acne Clearance Cold Laser Therapy in London is used to stimulate skin rejuvenation. Dermatologists use this therapy for treating various skin problems, including:

·         Acne and Acne Scars

·         Wound Healing

·         Burns

·         Vitiligo

·         Swelling of the skin

·         Dermatitis and Rashes

·         Psoriasis

·         Cold laser therapy is effective in treating difficult-to-heal wounds. 

Helps with Healing

It helps with the healing of burns, skin grafts, infected wounds or amputations. Acne Clearance Cold Laser Therapy in London increases the rate of regeneration of the skin and other tissues. It has also been found in poorly healing wounds, such as foot ulcers. It also improves the impact of burn scars.

Benefits for the Skin

It stimulates follicles and hair growth in people suffering from androgenetic alopecia. It has also been used successfully to treat psoriasis and was found to stimulate collagen formation in the skin and reduce wrinkles by treating them with only light, without the need for adding photosensitive products. The same could be verified to mitigate the damage caused by solar radiation.

Low-Level Laser Therapy is a conservative approach to burn scars. A correlation could be found between scar duration and improvement through LLLT. No adverse effects of Low-Level Laser Therapy have been reported yet. The present study shows that the 400 mW soft laser at 670 nm has a positive, albeit sometimes limited, the effect on gross appearance, pruritus, and pain-related burn scars. Hence, Scar Tissue Removal with Low-Level Laser Therapy in London is very useful.

Is Cold Laser Therapy For You?

The use of Low-Level Laser Therapy is rising in traditional medical practice and as a complementary or alternative therapy. It is approved by the United States Food and Drug Administration (FDA) for several conditions.

Cold laser therapy is considered safe when performed under the care of a qualified physician or professional. On the positive side, it is also non-invasive and painless. It also does not require medication or other preparation.

That said cold laser therapy should not be used on carcinomas or cancerous lesions. It should also be avoided in the thyroid or eyes for home use.

One of the drawbacks of this therapy can be time. While each cold laser therapy session only takes a few minutes, it can take up to a month (with up to four treatments per week) before you can evaluate its effectiveness.

It may not be covered by your insurance either.

Final Words

If you think Acne Clearance with Cold Laser Therapy in London is for you or your practice, please reach out for more information. Laser Medicine will be happy to help you find the perfect treatment for you!

Robot takes contact-free measurements of patients’ vital signs

The research described in this article has been published on a preprint server but has not yet been peer-reviewed by scientific or medical experts.

During the current coronavirus pandemic, one of the riskiest parts of a health care worker’s job is assessing people who have symptoms of Covid-19. Researchers from MIT and Brigham and Women’s Hospital hope to reduce that risk by using robots to remotely measure patients’ vital signs.

The robots, which are controlled by a handheld device, can also carry a tablet that allows doctors to ask patients about their symptoms without being in the same room.

“In robotics, one of our goals is to use automation and robotic technology to remove people from dangerous jobs,” says Henwei Huang, an MIT postdoc. “We thought it should be possible for us to use a robot to remove the health care worker from the risk of directly exposing themselves to the patient.”

Using four cameras mounted on a dog-like robot developed by Boston Dynamics, the researchers have shown that they can measure skin temperature, breathing rate, pulse rate, and blood oxygen saturation in healthy patients, from a distance of 2 meters. They are now making plans to test it in patients with Covid-19 symptoms.

“We are thrilled to have forged this industry-academia partnership in which scientists with engineering and robotics expertise worked with clinical teams at the hospital to bring sophisticated technologies to the bedside,” says Giovanni Traverso, an MIT assistant professor of mechanical engineering, a gastroenterologist at Brigham and Women’s Hospital, and the senior author of the study.

The researchers have posted a paper on their system on the preprint server techRxiv, and have submitted it to a peer-reviewed journal. Huang is one of the lead authors of the study, along with Peter Chai, an assistant professor of emergency medicine at Brigham and Women’s Hospital, and Claas Ehmke, a visiting scholar from ETH Zurich.

Measuring vital signs

When Covid-19 cases began surging in Boston in March, many hospitals, including Brigham and Women’s, set up triage tents outside their emergency departments to evaluate people with Covid-19 symptoms. One major component of this initial evaluation is measuring vital signs, including body temperature.

The MIT and BWH researchers came up with the idea to use robotics to enable contactless monitoring of vital signs, to allow health care workers to minimize their exposure to potentially infectious patients. They decided to use existing computer vision technologies that can measure temperature, breathing rate, pulse, and blood oxygen saturation, and worked to make them mobile.

To achieve that, they used a robot known as Spot, which can walk on four legs, similarly to a dog. Health care workers can maneuver the robot to wherever patients are sitting, using a handheld controller. The researchers mounted four different cameras onto the robot — an infrared camera plus three monochrome cameras that filter different wavelengths of light.

The researchers developed algorithms that allow them to use the infrared camera to measure both elevated skin temperature and breathing rate. For body temperature, the camera measures skin temperature on the face, and the algorithm correlates that temperature with core body temperature. The algorithm also takes into account the ambient temperature and the distance between the camera and the patient, so that measurements can be taken from different distances, under different weather conditions, and still be accurate.

Measurements from the infrared camera can also be used to calculate the patient’s breathing rate. As the patient breathes in and out, wearing a mask, their breath changes the temperature of the mask. Measuring this temperature change allows the researchers to calculate how rapidly the patient is breathing.

The three monochrome cameras each filter a different wavelength of light — 670, 810, and 880 nanometers. These wavelengths allow the researchers to measure the slight color changes that result when hemoglobin in blood cells binds to oxygen and flows through blood vessels. The researchers’ algorithm uses these measurements to calculate both pulse rate and blood oxygen saturation.

“We didn’t really develop new technology to do the measurements,” Huang says. “What we did is integrate them together very specifically for the Covid application, to analyze different vital signs at the same time.”

Continuous monitoring

In this study, the researchers performed the measurements on healthy volunteers, and they are now making plans to test their robotic approach in people who are showing symptoms of Covid-19, in a hospital emergency department.

While in the near term, the researchers plan to focus on triage applications, in the longer term, they envision that the robots could be deployed in patients’ hospital rooms. This would allow the robots to continuously monitor patients and also allow doctors to check on them, via tablet, without having to enter the room. Both applications would require approval from the U.S. Food and Drug Administration.

The research was funded by the MIT Department of Mechanical Engineering and the Karl van Tassel (1925) Career Development Professorship.
