Sure, it feels sexier, but that doesn’t even scratch the surface. Sleeping naked is legitimately good for your health — and, of course, it sexier. Here are all the reasons you should strip down before settling in to the sheets.

1. Your skin and hair will glow

Aside from making you toss and turn all night, being too warm at night also disrupts the release of melatonin and growth hormone — the two main anti-aging hormones. “As your body temperature drops, growth hormone is released and works its regenerative magic,” Natasha Turner, author of The Hormone Diet said. That “regenerative magic” is basically what keeps your skin youthful and hair luminous, all just from sleeping in your ~birthday suit~.

2. You’ll sleep better

So many studies have shown that sleeping in cooler rooms helps you sleep better, so maybe save the cute flannel PJs with scottie dogs on them for pre-bed lounging instead of actual sleep. “Your body temp progressively declines as you sleep, which is a natural tendency of the body, so being too warm with heavy PJs and blankets can disrupt that,” said Lisa Shives, MD, from the National Sleep Foundation’s board of directors. Sleeping naked is like ditching a blanket and keeping your body a bit cooler. Which = better beauty sleep.
3.
It’s better for your vagina

Tight, vag-hugging undies can be a warm, moist breeding ground for the bacteria that causes infections, and letting your vagina air out overnight by sleeping nude can help keep you healthy and clean. As Nicole Prause, an Associate Research Scientist at the University of California Los Angeles, told Medical Daily, sleeping naked reduces the ability of those bacteria to “overwhelm the normal healthy vaginal flora.”

4. Skin-on-skin contact is the best.

If you’re married, or living with your significant other, sleeping naked gives a greater chance of skin-on-skin contact, especially when it comes to cuddling. This kind of contact can also lead to a more active sex life. All of this releases copious amounts of oxytocin, which is the neurotransmitter that helps you feel those good feelings about your significant other.

5. It could lead to better sleep.
Let’s revisit the scenario I described above. There are no drawstrings or clothes getting tangled in sheets. You don’t have to worry about shirts getting twisted. All of these distractions go away when you sleep naked and it may help you get better, deeper sleep. You don’t need science to tell you that better, deeper sleep only helps you be healthier.

6. It can help your skin.

For once your body gets to breathe. Your private parts, armpits, and feet are generally restricted all day and are often covered by multiple layers, even in the summer time. Give those parts a chance to air out and breathe. This can lower the risk of skin diseases, like athlete’s foot, that result from wet, restricted skin.

7. Helps you regulate your cortisol.

Cortisol is a very strange chemical in the body but it can do a lot of damage. When you sleep naked, it helps keep your body temperature at the optimal ranges so your body can better create cortisol. If you sleep overheated your cortisol levels tend to stay high, even after you wake up. This can lead to increased anxiety, cravings for bad food, weight gain, and more terrible things. Sleep naked so you can keep your body temperature down and sleep well so your body can properly produce and regulate cortisol.

8. Balances your melatonin and growth hormone.

Continuing along that same vein, keeping your sleeping environment below 70 degrees (F) every night can help your body regulate its melatonin and growth hormone levels. These chemicals help the body do things like prevent aging and are essential to good health. When you sleep in clothes, your body heats up and prevents effective use of these hormones. In other words, sleeping with clothes on makes you grow old faster.

9. It can keep your sex organs happier.

For men, the cooler sleeping conditions allows your testes to remain at a cooler temperature. This helps keep your sperm healthy and your reproductive systems functioning as normal. For women, the cooler and more airy sleeping conditions can actually help prevent yeast infections. Yeast grows better in warm, moist conditions. When it’s cooler and dryer, the growth of yeast is prevented.

10. Sleeping in the summer is more bearable.

Summertime is a tricky time to get good sleep. If you don’t have air conditioning, then you may find your bedroom a bit stuffy at night. Shedding those bedtime clothes can help the bedroom feel more comfortable. You may even be able to turn the A/C off on those cooler nights, which can save you a few bucks on your electricity bill. Don’t wake up drenched in sweat again because your thermostat is downstairs and the hot air expands up to your bedroom where the thermostat can’t read the warm temperatures.
With these tips in mind, it’s time to start taking off your clothes at night! Of course, there are times where clothes are preferable. If you are ill or it’s cold outside, then you should sleep with clothes on to help you stay warm and prevent further illness. Otherwise, go commando!
