1. You’ll sleep better
Shedding your threads before tucking in will help you snooze
more soundly, says Men’s Health sleep advisor W. Christopher Winter, M.D. Your
body temperature declines as you doze and climbs before you wake up, but
clothing can interfere with this natural fluctuation, Dr. Winter says. The
extra insulation can make you too hot as your temperature drops, leading to
tossing and turning and waking up sweaty in the middle of the night. Nix the
PJs and allow your body temperature to ebb and flow uninterrupted, Dr. Winter
says.
2. You’ll ignite your metabolism
Staying cool throughout the night may help rev your
metabolism, according to a 2014 study in the journal Diabetes. Researchers
found that when people slept in a chilly room, they produced double the volume
of brown fat—a healthy fat stored in your neck that burns calories to generate
body heat—compared to when they slept in a warmer room. Keeping your body
temperature lower by sleeping nude could produce the same effect, says study
author Francesco S. Celi, M.D.
3. You’ll protect your testicles
Sleeping in your underwear increases the odds that you’ll
get an infection in the worst possible place, says Brian Steixner, M.D., a
urologist based in Atlantic City, N.J. Your drawers keep heat and moisture
in—and bacteria thrive in warm, moist environments, says Dr. Steixner. More
bacteria makes for a higher likelihood that any chaffed or irritated skin down
there becomes infected, he says. Skip your skivvies to keep your balls cleaner,
drier, and healthier.
4. You’ll nurture your sperm
Your scrotum needs to be just the right temperature in order
to optimize sperm production, says Dr. Steixner. That perfect temperature: 95
to 96 degrees, just slightly cooler than the rest of your body. When your
testicles are too warm, your sperm quality suffers, according to a Finnish
study that tested the semen of men who used saunas. Even tight underwear can be
enough to raise your sack’s temperature above the optimum level, Dr. Steixner
says. So for the sake of your future children, consider going naked.
5. You’ll get closer to your partner
Skin-on-skin contact with another person triggers the
release of the hormone oxytocin in your brain, according to Swedish
researchers. The chemical reduces stress, makes you feel more connected to your
partner, and increases your sex drive, the scientists say. And let’s state the
obvious: Brushing up against each other naked in bed often leads to good
things.
