  • Naked Gardening Day is in May, and World Naked Bike Riding are coming in June, and nude and

  • underwear runs happen all over the world, but all this naked celebration got me pondering

  • the intersection of nudity, health and science. Being naked helps us form a realistic body

  • positive connection to the human form. People who spend time naked have a better body image,

  • don't objectify as quickly, and are more confident and cozy in our skin! But outside of bonus

  • of a realistic self-image; there ARE concrete, scientifically proven benefits to being naked!

  • Firstly, being naked exposes more of your skin to the sunlight, which means more Vitamin

  • D exposure -- which is great -- and it helps your bones absorb calcium, so being naked

  • will help you get strong bones. But you also have to look out for UV radiation, so remember

  • sunscreen.

  • A study from the University of Reading claims if naked, we would have fewer parasites living

  • on our bodies overall. Humans are petri dishes as it is, we're constantly covered in bacteria

  • -- some good some bad. Clothing, like fur, promotes increased bacterial load by giving

  • it a comfy dark place to gather and spread. Since the invention of clothing, scientists

  • can point to specific evolution of lice and other human skin parasites,; though, unlike

  • fur we can swap our outfit when it gets too germy. But, by comparison, research looked

  • at the bacterial load on naked molerats and other hairless non-aquatic species and found

  • lower-than expected levels! So being naked, would likely decrease bacterial load on the

  • skin for humans too!

  • Sleeping nude has been shown to have myriad of scientific benefits. When the human body

  • settles into the sleep cycle, our temperature drops; which is why it's better to sleep in

  • a room that's less than 70 degrees [21C]. Research in the journal Sleep found sleeping

  • with clothes on prevents this natural cooling cycle. That cooling triggers the release of

  • human growth hormone from the brain, restoring skin and regenerating the body -- that regeneration

  • requires energy, which your body gets from fat -- which burns when we cool off during

  • sleep. Get naked, and you'll sleep BETTER because the body won't be fighting to control

  • your temperature. Plus, you decrease stress hormones like cortisol because you'll sleep

  • better overall.

  • Sleeping naked with a partner has some obvious bonuseswink wink; but less-than-obvious

  • is simple skin-to-skin contact during sleep. When skin touches during sleep -- even in

  • a non-sexual way -- the hormone oxytocin is released lowering blood pressure, decreasing

  • inflammation and lowering stress hormones. A study in Japan found sleeping with a bra

  • or girdle constricts the anatomy and can raise body temperature and decrease melatonin. So,

  • sleep naked at least, but that's easy! The rest of the day is a challenge, but there

  • are benefits there too.

  • For instance, though this doesn’t exactly make the case for total nudity, research shows

  • that neckties can be harmful to your health. A study in the British Journal of Ophthalmology

  • asked men to wear and tighten a necktie, while doctors monitored their intraocular pressure

  • -- a moderately tight tie caused physical changes to the eyeball which upped a risk

  • factor for the development of glaucoma! So do ditch the tie. And while you're at it,

  • ditch the tight pants too. The science is iffy, but some doctors claim tight pants for

  • men can inhibit sperm development, and tight clothing for women allow for bacteria to cultivate

  • in the vulva and within the vagina.

  • Hair or fur exists to keep animals warm, AND to protect them from the sun. We don't have

  • the fur, likely because we have one of the best sweat systems around! Sweatier humans

  • needed less body covering, because it interfered with the evaporation of that moisture. Clothing,

  • like artificial fur, interferes with sweatingso in case you didn't get the moral of this

  • little storyGET NAKED MORE.

  • Do you like being naked? Or are you a never-nude? When i get home, the first thing I do is take

  • my pants off. Seriously. Tell us how you feel in the comments. And

  • while were talking about skin, have you ever wondered how your skin is being affected

  • by the sun? You can find out in this video
