How to to Clean Our Indoor Air Properly Against COVID-19 | Time

*Outdoors is better than indoors

*Indoors requires either greater ventilation or scrubbing of the air (filtration)

*Most buildings have poor ventilation, and cold or hot weather mat require less ventilation

*In those cases, you need to scrub (filter) the air alongside ventilation

*Air duct filtration/UV may have limited value

*Much better to filter "in the room where it happens" using portable filters and Upper-room germicidal UV (GUV) fixtures (not personal UV scrubbers)

*Upper room germicidal is most cost effective for schools and businesses

*Ionization ineffective and causes irritants

TLDR: Mechanical ventilation, upper room UV, and portable room air cleaners

"Outdoors, dilution of any aerosols is infinite—though the time it takes to dilute clouds of aerosol, depends on air movement. Think, for example, of how a cloud of cigarette smoke outdoors lingers or dissipates depending on whether there’s a breeze or not.

Indoors, however, aerosols almost always linger longer than outdoors—often long enough to be inhaled by someone sharing the same space. Put another way, if you breath in an indoor setting where other people are also breathing, you will almost surely breath in some amount of air that has been recently exhaled by someone else. That recycled air—the so-called rebreathed air fraction—estimated by room carbon dioxide measurements, is a good predictor of the risk of infection, given an infectious person generating infectious aerosol in the same room....

Think About Ventilation

Ventilation, natural or mechanical, is the main way that the risk of airborne infection indoors is reduced. For hospital airborne infection isolation and procedure rooms, the U.S. Centers for Disease Control and Prevention (CDC) recommends 6 to 12 room air changes per hour (ACH) with infection-free outdoor air, or air that has been filtered or otherwise decontaminated. One ACH occurs when a volume of air equal to that of the room enters and leaves over a period of one hour. As fresh air enters and mixes with contaminated room air, not all the contaminated air is removed by one air change. Under well-mixed conditions, one air change removes approximately 63% of room air contaminants, and a second air change removes about 63% of what remains, and so on.

But under real world conditions, the protection achieved by ventilation also depends on the amount of contaminant (virus in this case) being added over time, i.e. by an infected person, and on the contagiousness of the infection. The greater the infectiousness of the virus, greater the infection-free ventilation needed to keep concentrations low.

For Omicron, for example, 6-12 ACH ventilation, or equivalent air disinfection, may not be enough to prevent transmission. Unfortunately, not all transmission is preventable by air disinfection—for example, transmission at very close range where there is no time to remove or inactivate viruses generated by one person before they are inhaled by someone else.....

Many residential and older buildings without mechanical ventilation may have about one ACH or less due to air leakage around doors and windows—but when windows are open, depending on building design, orientation, and outside weather conditions, may enjoy significantly higher ACHs. For economical heating and cooling, however, windows are normally closed, especially in larger mechanically ventilated buildings, by design, or closed by occupants in response to outside temperatures. Automated mechanical ventilation systems often bring in a minimum amount of outside air under very cold or hot outside conditions, resulting in most air being recirculated within the building, thereby recirculating air contaminants rather than removing them...

....because mechanical ventilation may not be sufficient to reduce the risk of infection, mechanical ventilation in public buildings should be supplemented by other methods of air disinfection. For current and future viral pathogens like SARS-CoV-19, relatively high levels of “equivalent” ventilation by supplemental air disinfection will be needed.....

....the value of high-efficiency filters or germicidal UV in recirculating ventilation ducts for preventing spread is speculative and limited at best....

A more effective air disinfection strategy is to rapidly decontaminate the air within the room where person-to-person transmission occurs.

“In the room where it happened” is a song from the Hamilton musical, but it could also be a guide to the application of air-disinfection technology....

....a small UV air disinfecting device designed to be worn around the neck cannot possibly move enough air to reduce aerosol transmission. Or, another example, small boxes with UV sources designed to decontaminate cell phones are likely no better than an occasional wipe down with alcohol. Equally irrational are GUV wands because delivering an effective germicidal dose is unpredictable when waving a wand over a surface, and they must be low power to avoid accidental direct over-exposure of eyes or skin. At an even larger scale, GUV portals have been marketed and used in building entrances or exits to “disinfect” people walking through them. This makes no sense not only because no significant decontamination of skin or clothing is possible, but respiratory virus resides in the human respiratory tract, and cannot be eliminated from the outside."

Advantages of UVGI in HVAC System

The outdoor air is polluted and is home to a number of harmful microorganisms. That’s why efforts have been made by the government and many other agencies to reduce the outdoor air pollution. However, most of the people are unaware that the indoor air can also be polluted and can contain microorganisms.

The Heating, Ventilation and Air Conditioning (HVAC) systems installed in residential and commercial buildings provides heating and cooling within the enclosed area. Shopping malls, offices, restaurants, airports, hospitals and other enclosed public places install HVAC systems. In such areas, there is no inlet of fresh air. The same air is circulated in the indoor environment again and again. Microorganisms grow and replicate as the air becomes stale. These organisms then infect a healthy person who is present in the enclosed premises.

Now-a-days many companies install air purifiers that clean indoor air. Many new technologies have come up in the recent past. UVGI is one such technology that completely kills all the microorganisms present in the air. UV air disinfection systems use the UVGI technology that not only purifies the indoor air but also removes harmful micro-organisms. Ultraviolet air sanitizing systems use ultra-violet rays to kill microorganisms.

UVHeal SafeAir is one such disinfectant system that purifies and disinfects indoor air effectively. Being modular in design, it can be easily installed into the existing or new HVAC disinfectant systems. This makes the whole process of installation stress-free. As UV light is used to kill the microorganisms, and no chemicals are used thus there are no by-products produced during the operations of this system. The UV light disrupts the DNA and RNA of the pathogens which kills them and disrupts their reproduction.

UVHeal SafeAir is easy to install, requires low maintenance and has low operating costs. Places like shopping malls, cinema halls, airports, etc. which have high footfall use UVHeal to disinfect indoor air. UV Heal can be controlled using a mobile app. These features make UVHeal SafeAir the best commercial air filter system. For More Information www.uvhealsafeair.com

Sun

Harringrove April prompt 15, Sun. After the Mindflayer, Billy’s kinda weird, but Steve figures that makes sense.

Steve took the kids to pick each other up, sometimes, and sometimes, Max was at the hospital, to see Billy. In Steve’s head, Billy nearly dying to save Eleven kind of...balanced out beating Steve’s head in. Didn’t mean Steve liked the guy, but he thought...well, Steve Harrington had been no kinda prize until he started fighting for kids, and maybe Billy had changed, at least a little.

Also, it was hilarious, because post-Mindflayer Billy Hargrove didn’t give a shit. Steve had thought he hadn’t before, but then he saw a nurse outside, trying to get Billy to go back in—or at least put his clothes back on—and Billy just leaning against the side of the building by the dumpsters, naked in the sun. She saw Max, and sighed with relief, heading inside.

Before, Billy had cared too much, Steve realized—about what Steve was doing, about who ruled the school—but he only cared about the sun, anymore.

That, and probably annoying his sister, some, because when she leaned around the corner of the building and yelled, “Billy Hargrove, put your damn pants on,” he leaned his head back, eyes still closed, and replied, “Don’t look over here and you won’t see anything you don’t like, Maxine.”

“You better have left your bandages alone,” she shouted, and he laughed, then grimaced, wincing.

“You better stop bossing me around,” he yelled back.

“You’re gonna freeze your ass cheeks off,” she hollered, her hands firmly over her eyes as she meandered hesitantly towards his voice.

“Don’t fucking come over here,” Billy groaned, bracing himself against the wall to look over, but one of his knees bent, and his legs both collapsed. He landed with a soft “—oop.”

“...can I look?” Max asked, stopping.

“No, don’t,” he muttered, trying to push himself back up, and Steve took a step forward automatically, grimacing.

“You are such a pain in the ass,” Max told him, putting her hands on her hips. “I’m gonna get you a wheelchair.”

“The sun’s only over here for like fifteen more minutes,” Billy hissed at her, squirming until he could lean back against the building, at least. “Lemme alone.”

“I can hear you shivering,” she snarled back. “You’re probably getting dirt under all your bandages. I’m getting a wheelchair.”

“Get the wheelchair,” Steve told her, and Billy twitched, but he didn’t open his eyes. “Once he’s in the shade, we can throw a blanket on him, and push him in the sun again.”

“...fine,” Max growled, and stomped off.

“...y’know if you leave a bottle of water in the sun for six hours, it disinfects it,” Billy said softly. “The UV rays.”

“...okay,” Steve said, keeping an eye out for anyone he needed to prevent walking around the edge of the building. Billy mumbled something, and Steve wandered closer, trying not to notice how thin his shoulders looked, or the irritated red skin peeking out from under his bandages. “...what’s that?”

“It doesn’t like the sun,” Billy whispered. “Can’t take the UV.”

“...you know it’s gone, right,” Steve told him, and Billy snorted a laugh, his knuckles whitening as he gripped at the scrubby grass.

“Mmm,” Billy said, and Steve crouched to grab his hand.

“Come on,” he said, “I’ll help you stand up.”

Billy laughed. “You’re gonna see shit and wish you hadn’t, Harringto—fuck,” he gasped, as Steve slid an arm around him, and slowly stood. “You’re warm, fuck,” Billy muttered, staggering, and shivering harder.

“We showered together,” Steve reminded him, trying to hold Billy so he faced the sun, but not touch him anywhere weird. “I’ve seen it all. I mean, you didn’t look as shitty, then.”

Billy laughed again, then took a few shuddery breaths, touching his bandages. “...fffuck,” he breathed. “I’m hot as...hell, Harrington,” he gasped, his whole face screwed up with pain. “Just...got no taste.”

“Yeah, that’s right,” Steve played along. “The stubble really helps. And the goosebumps, can’t forget those.”

“Shit,” Billy breathed, pulling him a couple of inches further into the sun. “...yeah. I gotta...hide back here,” he said, coughing, and groaning. “My public keeps wanting autographs.”

“...what about a tanning bed,” Steve asked, watching the last sliver of sun slide behind the laurels that shielded the dumpsters. “Surround you with the same thing, right?”

Billy’s breath caught. “...they’re not gonna let me out,” he whispered, curling a little against Steve’s shoulder, worn out. “I can’t get to one.”

“I will talk to your doctor, okay,” Steve told him. “Would you lie down and sleep, after? If we get you in one? Surrounded by the what, the UV light?”

Billy gripped his arms, and nodded, swallowing. “Y-yeah. I—I just need to—”

“Okay,” Steve nodded, as Max pushed the wheelchair around the corner.

Billy draped himself over the chair like a throne, and Max groaned at the drama, but tucked a blanket around him with annoyingly thorough pokes. Billy grumbled, batting at her hand.

Once Steve wheeled him into the room, Billy lolled his head back and hollered, “Max! You were so right, I’m dying, I need water.”

“Like a plant,” Steve said. “He needs to be watered. I kinda have to take a piss—”

“Sounds like you two can work that out,” Max said, wrinkling her nose, but running off.

“You piss on me and I’ll tear your dick off—” Billy started, then trailed off, watching her go. “Check my back,” he whispered, yanking at the blanket, and Steve grabbed his hands.

“Get in the bed,” he whispered back. “I can’t see anything with you in the chair. I’ll check.” Billy’s shoulders were bony in his hands, and Steve bit his lips, helping him back onto the hospital bed.

“...don’t get fresh, now,” Billy grunted, shaking with exhaustion as he flopped too far down on the bed, his feet hanging over the edge, but too tired to move.

“I would never,” Steve told him, snorting a laugh. “Lemme scoot you up—”

“Just look,” Billy hissed, clenching his fists, and Steve kept his sigh silent, and yanked back the blanket.

There were still a bunch of bandages down Billy’s back, and Steve grimaced, trying not to stare at a dude’s naked ass. “”You’re fine,” he sighed, and Billy slammed his hand against the mattress so hard the bed rolled a little.

“You didn’t fucking look—”

“I did,” Steve hissed back, and Billy shook his head, wrapping his arms around his pillow and his face.

“Look harder,” he whispered hoarsely. “Everything hurts, there’s something there this time—”

Steve rubbed his face, and then, grimacing, reached out and touched Billy’s shoulder. Billy gave a full-body shudder, flinching away. “—the fuck,” he gasped, sounding strained, but Steve just set his jaw and ran his fingertips down the back of Billy’s arm.

“I’m looking. There’s nothing.”

Billy stayed still, for once, letting Steve run his fingers down the whole length of his body as Steve’s face flamed. When Steve finished running his fingers down Billy’s sides and along his legs and feet, he stuck his arms out behind him, and Steve carefully inspected his hands and forearms for black veins.

“Back here,” Billy said, grabbing his hair off his neck, and Steve leaned in to inspect the back of Billy’s neck, and behind his ears, listening to the panting, snuffly breaths he was taking into the pillow.

“You’re clear,” Steve said, and Billy finally relaxed, swallowing hard.

“...fuck,” he muttered, between slow, shaky breaths. “Shit. I thought—”

“Try to get some sleep,” Steve told him, sighing. “You’re fine.”

“I’m so fine,” Billy muttered into his arms, huffing a laugh.

Steve thought about telling someone that “looking” with fingertips worked, but he couldn’t see Max wanting to try it, or Billy letting her.

“...you want me to come look tomorrow?” Steve asked, resignedly, and Billy went really still. “...I can check for you if you’ll feel better.”

“...you just wanna get your hands on my ass,” Billy whispered finally, his voice cracking.

“That’s definitely it,” Steve snorted, pulling the blanket back over him, and tucking it in. “Stay under there, it didn’t like warm either, right.”

When Max came back in, she had a tray of food, and started bickering with Billy over the applesauce on it, so Steve left. As he opened the door, Billy called out “Tomorrow?”

“Tomorrow,” Steve agreed.

He tried to find Billy’d doctor to ask him about a tanning bed, and then the nurse on duty, but she must have thought Billy wanted a tan, because she rolled her eyes. “That kid is gonna die of vanity,” she said, and Steve laughed uncomfortably.

When he’d been at the grocery store, they had cactuses. He drove over there and wandered around until he found a lady holding flowers, and grilled her on how to make somewhere warm and sunny enough for a cactus. After writing a lot on his hand about grow lamps and minimum temperatures, he turned away, and she said “...you aren’t gonna buy a cactus?”, so he did. He picked out an especially spiky one to call Billy, and a shorter wooly one that looked like it was crouching to lunge, and called that one Max with great satisfaction.

The hardware store didn’t have grow lamps, so he ordered two, and bought some bulbs. When he got home, he put Billy and Max into the window, and carefully watered them, then frowned at them through the evening, half expecting them to wither and die.

The next day, Billy was waiting for him after work, his hands shaking a little, but he looked less exhausted.

“You get some sleep, finally?” Steve asked, pulling Billy’s hair away from his ears to check, and then lifting it off his neck.

“Don’t get distracted,” Billy muttered.

“Yeah, yeah, I gotta appreciate the sights, right,” Steve sighed, and Billy laughed, relaxing already under Steve’s careful fingers.

“What about under the bandage,” Billy whispered, when Steve’s fingers grazed his ribs. “Where it went through me.”

“Doesn’t the nurse change that out every day,” Steve asked, having seen it, and Billy’s fingers clenched around the edges of the mattress.

“She’s not looking, she thinks I’m nuts,” he growled, and Steve grimaced, lifting the edges to look underneath.

“I think they’ll throw me out if I mess with your bandages. How about you have Max watch?”

“...she doesn’t wanna see that,” Billy muttered, and Steve rolled his eyes, thinking ‘because I do, right.’

“She wants to make sure you’re safe too,” he told Billy, who was silent.

“His room at home doesn’t get any sun at all,” Max said, when she showed up, and Steve frowned at the man huddled under the blankets. “He’s gonna get arrested for flashing the neighbors. And probably, like, skin cancer on his dick.”

Both options seemed likely.

“When are they releasing him?” Steve asked, cocking his head thoughtfully, and Max winced, blowing through her cheeks.

“We don’t know. He keeps talking about how he could stay longer if he fell down the stairs,” she said, smiling grimly.

“...what the fuck,” Steve said, staring at her, and his vague thoughts of Billy coming to visit began to take shape.

“What?! No!” Robin said, when he mentioned the idea of inviting the man who’d given him a concussion to live in his house.

“He’s changed,” Steve said lamely. “And he’s got no strength in his arms,” he pointed out, with more certainty. “He’s not gonna be hitting anybody.”

“We can always fling him off your balcony,” she said, considering.

He broached it to Billy the next day, as he ran his fingertips down the warm, goose pimply skin of Billy’s thighs. “You should come to my apartment,” he said, and Billy’s foot twitched.

“...the hell would I wanna go visiting anywhere,” he asked. “Don’t get distracted—”

“I’m not, look, I’m stopping here, I’ll restart in the right spot,” Steve said, resting his whole hand on Billy’s thigh just below his ass. He shivered. “I’m saying come stay with me, okay.”

After a long pause, Billy lifted his head from the pillow. “...what,” he croaked.

“Come stay with me.”

“...are you fucking serious,” Billy shot back, glaring over his shoulder. “Don’t fuck with me, Harrington—”

“I’m not,” Steve sighed, rolling his eyes. “My apartment faces south, man, sunny all day.” Billy’s breath caught. “Think about it,” Steve told him, bending to carefully check Billy’s legs for the black veins of the Mindflayer.

That night, Steve’s phone rang. “Were you serious?” Billy said, with no preamble. “I can come stay with you?”

“Yeah,” Steve said, winding the cord around his finger, his cheeks irrationally flushed. It was just Billy, he told himself, glancing around the apartment and wishing it was nicer. The carpet looked older than Steve was, he thought in dismay.

“For how long,” Billy said softly, like there had to be a catch, and Steve shrugged.

“Doesn’t matter, Hargrove, jesus. I can’t let you go home.”

“...the hell did Max tell you,” Billy hissed, and Steve blinked.

“She said your room had no sun.”

Billy started laughing—Steve hoped the noise was laughing, anyway, at least mostly—and then hung up.

The day Billy was released, Steve took him straight to a tanning salon, and he emerged half-asleep from the tanning bed, so sleepy and quiet he didn’t even resist Steve carrying him back out to the car.

He did have a lot to say about getting piggy-backed up the stairs to Steve’s apartment, like “Giddyup”, “Yee-haw”, “You just want me wrapped aorund you,” and “What the shit, Harrington, three stories, I’m gonna be trapped up here like fucking Rapunzel.”

“Didn’t a king put her in a tower to weave gold,” Steve asked, panting, and Billy laughed against his shoulder.

“That was Rumpelstitzkin. Wrong story. Rapunzel, a witch did it. They traded her for salad.”

“They fucking what,” Steve said, staggering to a stop on the stairs, and Billy burst out laughing.

“Keep walking, your majesty. Don’t drop me.”

Steve reached and flicked the lights on, and then carried Billy inside. His mom had gotten rid of his kid’s bed, so he’d just hauled his queen size out to the front room, in front of the windows, and he lowered Billy next to it, turning to grab him as he stumbled, looking around.

“...there’re cactuses growing on your windowsill,” Billy pointed out, and Steve nodded.

“It’s so sunny in here cactuses grow,” Steve informed him proudly. “I thought that one looked like you—”

“Sturdy?” Billy suggested, smirking. “Prickly?”

“Pain in my ass,” Steve told him. “Here, sit down before you fall down. Okay, these lamps?” he pointed, walking over, “—sun lamps, okay. They’ll keep it sunny year-round—”

“...why do you care if it’s sunny year-round,” Billy asked flatly, and Steve blinked over at him. “I already don’t know how I’m gonna pay you back for this,” Billy gritted out. “The fuck do you mean year-round.”

Steve bit his lips together, thinking how weird and pathetic it was that he’d been so excited to have Billy come he’d lost sleep, bought grow lamps and cacti, and scrubbed his whole fridge out that morning at three, after it occurred to him, lying awake, that he hadn’t since he moved in. He walked into the kitchen, and started getting out the chicken soup fixings he’d been assured Billy could eat. “...I put a plastic lawn chair in the shower for when you can take showers,” he said, and heard his bed creak. He looked over to see Billy standing, gripping the headboard, but then he sat again, swearing.

“Harrington,” he hissed.

Steve told him about the hours he kept, and the plan with Max to bring Billy’s things, and Billy muttered darkly, and eventually complimented Steve’s soup like he was mad to admit it was good.

That night, he squirmed next to Steve, slowly, because he couldn’t move fast, his breathing catching, then evening out, then gasping again.

“...you need anything?” Steve asked finally, and Billy was silent for a long time, like he was holding his breath.

“Maybe I should shave my head,” he said, casually, out of the blue, and Steve couldn’t help it, he snorted a laugh, dissolving into snickers.

“What?!” he hissed, still giggling.

“Can’t check under my hair,” Billy said, nearly inaudibly, and Steve groaned, then scooted closer, and reached up to find Billy’s shoulder in the dark.

He slid his hand up and through Billy’s curls. “S’warm, right?”

“...yeah,” Billy breathed.

“Doesn’t like warm,” Steve whispered back, sliding his fingers through every inch of Billy’s hair, slowly, so heat could build. “If this feels bad, we’ll know, right?”

“......yeah,” Billy said, after an even longer pause.

“...so does it?” Steve asked, after a while, and Billy didn’t answer. Steve suspected he’d fallen asleep, but he made sure to finish.

While Steve got ready for work, Billy was arranging himself in the bed, centered in the windows with his naked ass hanging out. He sighed contentedly, and Steve groaned.

“Tell me you put sunscreen on,” he said, and Billy glared over.

“I can’t put a shirt on, Harrington. It’s fine—”

“You’re gonna be pissed if you get sunburned,” Steve told him, grabbing the sunscreen he’d bought for the time he took the Party camping, before they were too old for fun. Billy stared at him, but Steve had had girlfriends, and he was a good babysitter, so he was an expert at warming sunscreen just enough, and not letting his fingers linger anywhere they weren’t supposed to be.

Billy lay stiff as taxidermy as Steve rubbed sunscreen into his shoulders and arms, and then down his back—and then paused, because usually there was swimsuit there, and Billy cracked up the hardest Steve had ever heard him laugh. He ever kicked his foot a little, snickering at Steve’s bad life choices.

Steve slapped a lotion-gooey hand on Billy’s ass, defiantly, and Billy yelped, laughing harder, and curling a little on his side, so Steve had to shove him on his face again to get him around the side of his butt.

“What are you doing,” Billy groaned into his pillow, cackling as Steve got his thighs and down the backs of his knees.

“I just don’t wanna find you burned to ashes, like a vampire,” Steve said, blushing harder than ever, and then patted the calf of Billy’s leg. “Flip over.”

“...I’ll get the front,” Billy said, still sniggering. “I promise. I swear, Harrington—”

“...you better,” Steve said, a little relieved, and a lot disappointed. He shook his head hard, and left the sunscreen where Billy could get it.

When he glanced back, Billy’s whole body was much redder than Steve’s squeamish lotioning could explain.

That night when he got home from work, he brought a pizza. Billy eyed it doubtfully, but accepted the offered plate. He stayed on the bed, watching Steve watch TV, until Steve waved him over, making a face.

“D’you need help getting off the bed, or something?” he asked, and Billy shook his head, narrowing his eyes.

“Not gonna risk it,” he said. “You felt me up too good this morning. Might get ideas.”

Steve threw an olive at him, and Billy popped it in his mouth. Steve watched him lick the drooping tip of the pizza into his mouth, and the grease shining on his lips. Steve cleared his throat, and fixed his eyes on the TV screen.

“So if I’m the spiky one,” Billy said, pausing halfway through the pizza slice to lay back on the bed, “—who’s the other one? You got two cactuses in your life?”

“Max,” Steve told him absently. “I was asking the lady at the store how to keep it sunny enough for a cactus in here, and so she thought I’d buy some, y’know.”

“...I guess when you start bringing a girl around, you’ll get something pretty,” Billy said, not any particular way, and Steve realized he’d been listening closely for tone.

“Cactuses have flowers,” Steve told him, and Billy pushed himself up again, watching Steve’s face.

Steve didn’t know what to do with that, except stick his tongue out, or something, so he stuffed the whole rest of the pizza slice in his mouth, and chewed.

Billy could mostly take care of himself, except for being a little crazy. Steve asked Dustin what it was called if something couldn’t live without sunlight, and Dustin said photosynthesis, so that was what Steve told his neighbors Billy had. He jerked awake nearly every night no matter how long he baked himself the night before, breathing shakily. Sometimes, it worked for Steve to slide a hand over and touch his shoulder, and then smooth his hand over Billy’s skin, reminding him the Mindflayer didn’t like it warm.

“You could just look, and we could go back to sleep,” Billy mumbled, but he scooted closer as Steve smoothed a hand along his ribs, and down his hip.

“Too sleepy, no lights,” Steve groaned, flopping half on top of him, and Billy laughed until they were both awake.

Once, he tried to escape Steve, who scrambled the other way, thudded to the floor with a loud crash at 3am, and woke the neighbors, who yelled up through the floor asking if they were okay.

Billy and Steve snickered in horror over that one, and Steve tried to sleep on the couch, that night, despite Billy’s continual whispers of “You know you’d rather get some, Harrington. Get back over here. I’m lonely, Harrington. Put your hands on me, Harrington.” He started singing it, softly, then louder, like their neighbors weren’t tortured enough, and finally Steve groaned, laughing, and tromped back over to crawl into bed.

“You want my hands on you, huh,” Steve whispered, daring to scoot close and slide a hand around Billy’s waist, pulling their whole bodies against each other. “...warm enough?” he asked, and Billy nodded, frozen stiff like a board against his chest.

“...what were you dreaming?” Steve whispered, against Billy’s ear, because usually Billy curled into his warmth, edging towards him even asleep, until they were a mess of arms and legs and their skin stuck together a little with sweat.

Billy took a slow breath, then let it out. Steve waited, but he just kept...breathing, until Steve finally grunted unhappily against his neck, and snuggled closer. They didn’t get much sleep, that night, since Billy kept twitching awake, and finally Steve got up and turned on the sun lamps, and yanked off the blanket to run his hand up and down Billy’s lower back.

“...d’you wanna kiss me,” Billy finally said, flatly, like he was mad, and Steve froze.

He thought about the way Billy knew exactly how to make Max mad—but teased her about something else, instead, after listening to her scream as he went down at the mall. The shine of the pizza grease on Billy’s lips, and how pink they’d been, after he licked them. How he sat up a little every time Steve walked in the room, like Steve Harrington was someone to get excited about.

“...you don’t, do you,” Billy said, even more firmly, his hands clenched on Steve’s, around his waist. “Fuck. Forget it.”

“What the hell, no, I’m not forgetting it,” Steve hissed, and Billy laughed, less happily, this time.

“Yeah,” he whispered. “That’s what I was dreaming about.”

“What if—what if I do. Want to,” Steve mumbled, feeling like a moron, and Billy went all stiff and uncomfortable in his arms again.

“Make up your mind, Harrington,” he growled, and Steve sat up, so Billy fell on his back with a sputtered “Fuck!”

Steve licked his lips, staring down at Billy’s glowering face and set jaw, going golden in the first, early rays of the sun. He leaned in for a kiss.

The UV light terminates microorganisms that are present in the indoor AC air. This UVC disinfection system is very effective in enclosed areas that use centralized AC systems. Enclosed places like hospitals are filled with bacteria and viruses. Thus continuous disinfection is essential to maintain a clean and safe environment. UV Light Disinfection in Hospitals is a must as it destroys the DNA and RNA of the microorganisms and stops them from replicating. For More www.uvhealsafeair.com/air-disinfection-in-hospitals.html

AÇIK HAVA VE GÜN IŞIĞI

Prof. Dr. Canan Karatay 07.03.2021

Gün ışığında dolaşmanın ve temiz hava solumanın SARS-CoV-2, COVİD-19 grip infeksiyonunu engelleme ve önlemede son derece önemli iki faktor olduğunu bir kez daha belirtmek istiyorum. Gene tarihten ve yaşananlardan ders almamız gerekiyor.

Şöyle ki bir örnek verecek olursak, 1918 İspanyol gribi salgınında, açık havaya yerleştirilen hastaların, ölüm oranlarının, kapalı hastahane koğuşlarında yatanlara oranla daha düşük olduğu bildirilmiştir [1]. Bir çok çalışmada da, doğal olarak havalandırılan koğuşlarda, açık havaya kapalı ve mekanik olarak havalandırılan modern hastahane koğuşlarına oranla temiz hava değişiminin oldukça düşük olduğu gösterilmiştir [2].

Temiz hava değişimi kapalı bir mekan ya da bir oda içine, ne sıklıkla taze, temiz havanın girdiğini gösterir. Örnekleyecek olursak, bir pencerenin açılmasıyla kapalı mekan ya da oda içine, bir saat içinde %69 oranında temiz hava girmektedir. Mekanik ventilasyon ile saat başı hava değişiminde ise bu oran

%12 dolaylarında olup çok düşük bir değerdir.

Kapalı ortamlarda, solunan havada virüsün yoğunluk oranı, ya da konsantrasyonu artmakta ve infeksiyon yapma olasılığı kat kat yükselmektedir. Aynı şekilde SARS-CoV-2, COVİD-19 grip infeksiyonu ve tüm kış grip infeksiyonlarının da, kış aylarında soğuk algınlıklarının artması kapalı ortamlarda, havasız kapalı ve kalabalık olarak yaşandığından kaynaklanmaktadır.

Bu nedenle hastahanelerde olduğu kadar, gerek evlerde, gerek kapalı olan yaşam ve çalışma ortamlarına açık ve temiz havanın girmesi, ve saydığımız bu kapalı mekanların sık sık havalandırılması son derece önem kazanmaktadır. Almanya, Kanada ve ABD’de yapılan araştırmalar, bir kişinin hayatının yarısının ev içi havasını solumakla geçtiğini göstermiştir [3].

Akıllı binalarda maalesef pencereler açılamamaktadır. Bu nedenle, başta SARS-CoV-2, COVİD-19 virüs gribi olmak üzere tüm kış gribi ve infeksiyon hastalıkları sıklıkla görülmektedir.

Temiz Hava solumanın faydaları uzun senelerden beri bilinmektedir ve bir çok çalışama ile gösterilmiştir. 1894 yılında Londra’da yayınlanmış olan bir çalışmada, temiz havaya maruz kalan tüberküloz mikrobunun, hastalık yapma gücünün çok zayıfladığı bildirilmiştir[4].

Temiz hava solumanın antimikrobik olan önemli etkilerini bir kaç faktörle özetlemek mümkündür. Güneşli açık havada yürümek ile, bir kere güneşin UVB ışınlarına maruz kalmaktayız. Açık havada virüs yoğunluğu, konsantrasyonu azaldığı gibi, hastalık yapma gücü de zayıflamaktadır. İşte bu nedenle dışarıda açık havada bol bol yürümek viral infeksiyonların riskini azaltmaktadır. Maskenin bir faydası bu bağlamda yoktur.

Temiz havanın antimikrobik etkisine, 1960 yıllarında, ‘OPEN AIR FACTOR- OAF’ denilmesinin nedeni budur[5]. Açık temiz havanın İNFLUENZA virüslerini yok ettiği, ben İngilterede çalıştığım, 1972 yıllarında, Hijyen Tıp Dergisinde yayınlanmıştı.[6]. Temiz havanın antimikrobik etkisinin temel nedeni olarak, gün ışığı ile havada bulunan ozon partiküllerinin etkileşim sonucu ortaya çıkan hidroksil radikalleri diye adlandırılan kimyasal ögelerin olduğu açıklanmıştır[7].

SÖZÜN ÖZÜ:

GÜN IŞIĞI ve AÇIK TEMİZ HAVA içinde bulunan bileşenler, asırlardan beri, hastalık yapan mikro organizmaları azaltarak, yok ederek insanları bakteri, virüs ve mantar infeksiyonlarının neden olduğu öldürücü infeksiyonlardan kollamak ve korumaktadır. Bu faktörler mevcut olmasa idi insanlar ve hayvanların tümünün hayatta kalabilmeleri mümkün olamazdı. Dünyada canlı yaşam imkansız olurdu. Yabani hayvanlara da maske takalım mı, ne dersiniz?

SARS-CoV-2, COVİD-19 salgınına karşı, tarihten alınacak oldukça önemli derslerin var olduğu bir gerçektir.

O halde, SARS-CoV-2, COVİD-19 salgınını önlemek amacıyla kitleleri tamamen eve kapanma uygulaması yanlış ve tehlikeli olduğu aşikardır. Evde kapalı ortamlarda virüsün tehlikesi daha da artmaktadır. Açık havada yürümenin yasaklanması, ya da denize girmenin yasaklanması acaba ne kadar doğru bilimsel bir uygulama olmaktadır?

Sağlık Bakanı Sayın Fahrettin Koca’nın da ifade etmiş olduğu gibi, SARS-CoV-2, COVİD-19 virüs grip infeksiyonu evlerde daha büyük risk oluşturmasına ve daha hızlı yayılmasına neden olmuştur. Özellikle 65 yaş üstü sıhhatli gençlerin, sokağa çıkma kısıtlamaları/yasağı bilimsel olmayan, üstelik bir çok hastalık riskinin artmasına neden olan bir uygulamadır.

Daha önce de bir kaç kez açıklamış olduğumuz gibi gün ışığının, cildimizde D VİTAMİNİ yapımını sağlamaktadır. Ancak gün ışığının bilinen bir çok başka önemli faydaları da bulunmaktadır. En başta, gün ışığının Ultra Viyole B yani UVB ve Ultra Viyole C yani UVC, ışınlarının sıhhatimizi koruma açısından son derece önemli yeri vardır. UVB ışınlarının virüslerin büyük çoğunluğunu öldürdüğü senelerden beri bilinen bilimsel bir gerçektir[8] yeni bir buluş değildir. Ultraviyole ışınlarının, ya da kısaca UV ışınlamasının ile, SARS-CoV-2, COVİD-19 virüs salgınıın önlenebileceği anahtar bir uygulama olduğu da açıklanmıştır [9]. UV yani gün ışığının, 1877 yılından beri yüzlerce çalışmada infeksiyonların yayılmasını önlediği NATURE dergisinde yayınlanarak bildirilmiştir [10] [11] [12].

SARS-CoV-2, COVİD-19 infeksiyonu korkusundan, yaygın olarak aşırı miktarda kullanılmakta olan yüzey dezenfektanları son derece sıhhati bozmaktadır. Bu nedenle bir çok kişide çeşitli sağlık sorunları baş göstermeye başlamıştır. Özellikle, okul, TV stüdyoları, hastahene, ve AVM’ler gibi kapalı alanların havasının geceleri UV ışınları ile dezenfekte edilmeleri, yaygın bir şekilde sıhhati bozan kimyasal dezenfektan kullanımı yerine, insan sağlığına zarar vermeyen UV ışınları nın kullanılması tercih edilmelidir [13].

Gün ışığında bulunan Ultra Viyole yani UV ışınlarının her türlü mikrobu yok etmede son derece güçlü olduğu bilinmektedir. Öyleki, terör amacıyla, yani biyoterörizim amaçıyla yayılan her türlü tehlikeli mikrobiyomu öldürme, korunma ve yayılmasını önleme amacıyla UV ışınlarının kullanılması önerilmektedir[14].

UVB ve UVC Ultraviyole ışınlarınıın bütün virüsleri öldürdüğü veya yok ettiği bilinmektedir. UVB ve UVC ışınlarının bu bağlamda, bütün Corona virüslerini ve de en yeni olan SARS-CoV-2 virüsünü ayırt etmeyeceği ve SARS-CoV-2 virüsünü yok edeceği aşikardır. ABD COLUMBİA Universitesi araştırmacılarından Biyofizik Profesörü, PhD David Brenner kış gribine neden olan bütün mevsimsel TÜM CORONA VİRÜSLERİNİ ki buna SARS-CoV-2 virüsü de dahildir, % 99, oranında yok ettiğini ve insanlara zarar vermediğini bildirmiştir.

“Far-UVC light doesn’t really discriminate between coronavirus types, so we expected that it would kill SARS-CoV-2 in just the same way: since SARS-CoV-2 is largely spread via droplets and aerosols that are coughed and sneezed into the air, it’s important to have a tool that can safely inactivate the virus while it’s in the air, particularly while people are around. Because it’s safe to use in occupied spaces like hospitals, buses, planes, trains, train stations, schools, restaurants, offices, theatres, gyms, and anywhere that people gather indoors, far-UVC light could be used in combination with other measures, like wearing face masks and washing hands, to limit the transmission of SARS-CoV-2 and other viruses.”

SONUÇ:

Evlerde kapalı ortamlard YAŞAMAK değil, kalabalıktan uzak maske takmadan, açık havada yürümek, kalabalıktan UZAK OLARAK maske takmadan, gün ışığında, ormanda yürümek, kalabalıktan UZAK OLARAK maske takmadan, deniz kenarında yürümek ve de denizde yüzmek SARS CoV-2, COVİD-19 virüsünü de zayıflatmakta, çoğalmasını engellemekte ve yayılmasını önlemektedir. Kalabalıktan uzak kaldıkça, açık havada fizik aktivite sırasında maske takmak, hipoksiye neden olduğu için sakıncalı ve tehlikelidir.
