According to a recent study, about 10% of American sleep without any clothes on. But apparently we should ALL be doing it. Here are a few benefits of sleeping in the buff.  

~  It Airs Out Your “Ladies & Gentleman.”  Which is good for both genders 

~  You Sleep Better When You're Naked. "Your body temperature progressively declines as you sleep, which is a natural tendency of the body.  So sleeping with heavy pajamas and blankets can disrupt that."  

Or in other words, sleeping in pajamas or using a lot of blankets can actually make you TOO warm at night, which makes you toss and turn and prevents you from getting enough R.E.M. sleep.  

~  You'll Look Younger.  Being too warm at night also messes with how your body releases certain anti-aging hormones.  

When your temperature DROPS it's a good thing, because more hormones get released that help regenerate skin cells, and keep your hair looking healthy.  

~  You Might Have More Sex.  And no, not ACCIDENTALLY.  Skin-on-skin contact increases certain hormones like oxytocin, which is sometimes referred to as the "love hormone."  

~  You'll Lose Weight.  When you sleep through the night without tossing and turning, it gives your body a chance to lower the amount of cortisol you're getting, which is a stress hormone.  

If you wake up with too MUCH cortisol in your system, it makes you hungrier, which means you're more likely to eat a big, unhealthy breakfast that you don't actually need.
