Snoozing without clothes can improve sleep by helping you stay cool. It may also offer additional health perks, such as supporting reproductive wellbeing.
Going to bed without pajamas might not be the first health tip that comes to mind, yet some advantages are worth considering. Since it’s simple to try, you might consider shedding some layers and catching your z’s — for your wellbeing, that is.
It turns out there are multiple upsides to sleeping nude. You may recognize a few of these, and others could be pleasantly surprising.
1. Fall asleep quicker
Your core temperature plays a key role in how easily you drift off. It’s part of your circadian rhythm, the internal timing system that signals when it’s time to sleep.
Lowering your body heat tells your system it’s bedtime, so sleeping without clothing — allowing your temperature to drop — can help you nod off faster.
2. Improved sleep quality
Not only does cooling your body help you fall asleep sooner, but it also enhances overall sleep quality. The recommended bedroom temperature is roughly 60–67°F (15–19°C).
An earlier 2012 study from the National Institutes of Health found that room temperature is among the most critical factors for getting restorative sleep.
If the room is too warm or too cold, you can disrupt REM sleep — the dreaming phase that refreshes the brain and body. Sleeping naked is one way to remain cool under the covers.
3. Supports skin health
Because sleeping without clothes can increase sleep quality, it can also benefit your skin. A small 2018 study examined whether inadequate sleep impaired the skin’s ability to heal minor wounds.
Participants were split into three groups: those who got adequate sleep, those who were sleep-deprived, and those who were sleep-deprived but received extra nutrients.
The well-rested group healed faster than the other two. The additional nutrition didn’t significantly speed up wound recovery.
That suggests sufficient sleep helps skin repair and stay healthy — so if sleeping nude aids that, it’s an added benefit.
4. Reduces stress and anxiety
Another reason to try sleeping nude is that it may help lower stress and anxiety. Poor sleep is well known to worsen stress levels. A large 2020 study indicates sleep problems can contribute to prolonged depressive symptoms and suicidal thoughts in people with depression.
While anxiety and stress can trigger insomnia, improving sleep quality and obtaining enough rest may help alleviate these issues.
5. Helps prevent weight gain
Poor sleep can have many negative health consequences.
A 2022 review found that people sleeping seven hours or fewer per night are more prone to gaining weight.
Another potential way sleeping nude could support a healthy weight is by keeping your body cooler at night, which may boost calorie burning. A small 2014 study of five men showed that exposure to cooler temperatures, about 66°F (19°C), increased brown fat activity.
6. Lowers risk of heart disease and type 2 diabetes
Insufficient sleep raises the risk of developing type 2 diabetes, according to a 2016 review. Type 2 diabetes, in turn, elevates heart disease risk.
By enabling you to fall asleep more quickly and remain asleep, sleeping nude could influence these long-term health outcomes.
7. Promotes vaginal health
Sleeping naked can also support vaginal health and reduce the likelihood of yeast infections. Tight or sweaty underwear can promote yeast growth because it thrives in warm, moist environments.
No matter what you wear during the day, going without clothes at night is an easy way to let the area breathe and stay healthy.
8. Enhances male fertility
Men can gain advantages from sleeping without clothes as well. A 2018 study of 656 men found an association between tight underwear and lower sperm counts. Men who wore boxers had greater sperm concentration and total sperm count than those who chose tight undergarments.
Sleeping nude helps keep the testicles cooler, which supports optimal conditions for sperm health.
9. Boosts self-esteem
Sleeping nude can also help you connect with your body and raise self-esteem.
A 2021 study links time spent unclothed to increased body appreciation, which is a positive step toward self-acceptance.
10. Strengthens your relationship
While sexual activity can benefit relationships, sharing a bed naked with your partner has its own rewards. A 2015 study found that skin-to-skin contact between adults prompts oxytocin release, a hormone important for bonding between partners.
Even better: touching your partner benefits both your relationship and your health — and sleeping nude is a simple way to gain both advantages.
The takeaway
If sleeping entirely without clothes doesn’t feel right, reducing the number of layers you wear — or simply skipping your bra or underwear — is an easy way to enjoy many of these benefits.
The key is prioritizing sufficient, high-quality sleep.
