You probably know that we spend about a third of our lives sleeping. You also know that sleep—its duration and quality—is crucial for the body's regeneration processes.
But did you know about the benefits of sleeping naked?
Sleeping naked is particularly popular during the summer months when hot weather makes it difficult to maintain an optimal bedroom temperature.
Sleeping without clothes significantly improves sleep quality. The absence of clothing in bed helps the body relax more, making it easier to fall asleep.
It’s no surprise—after an entire day of wearing tight underwear and fitted clothing that cause excessive sweating, our skin needs a break. At least at night, we should allow our bodies to rest properly.
How does what we wear to bed affect our sleep?
A recent study conducted by the National Sleep Foundation revealed that the percentage of people who sleep without underwear is:
🇬🇧 30% of Britons
🇨🇦 14% of Canadians
🇲🇽 12% of Mexicans
🇩🇪 9% of Germans
🇵🇱 13% of Poles
Meanwhile, an ABC News telephone survey found that 22% of Americans sleep naked, with men being twice as likely to do so as women.
In Lithuania, it is estimated that around 10% of people sleep naked.
So, is sleeping naked actually healthy?
It is well known that the optimal bedroom temperature for quality sleep is between 18 and 20°C. Temperatures that are either too low or too high can negatively affect sleep quality.
For this reason, some believe that sleeping naked helps the body cool down faster, ensuring better sleep—especially in hot weather.
Sleeping naked may slightly lower skin temperature without changing the overall bedroom temperature. Additionally, it can improve circulation—but the benefits of sleeping naked don’t stop there.
The Benefits of Sleeping Naked
There are many theories confirming that sleeping without clothes is beneficial for health. Sleeping naked:
✔️ Increases growth hormone and oxytocin (the love hormone) levels
✔️ Helps maintain intimate hygiene
✔️ Aids in hormone regulation
✔️ Allows better airflow to the skin
✔️ Prevents overheating, helping the body stay cooler, which in turn boosts metabolism during sleep

The Benefits and Considerations of Sleeping Naked
Sleeping naked provides a feeling of lightness and freedom, positively affecting overall well-being.
Preventing Intimate Infections
It is a fact that sleeping naked significantly reduces the risk of intimate infections, particularly for women. Without underwear, bacteria growth is minimized, creating a healthier environment.
For women, sleeping naked helps prevent vaginal yeast infections, also known as thrush. Excess yeast growth leads to inflammation, itching, and discomfort, and is often worsened by poor air circulation caused by tight-fitting underwear. Choosing to sleep without restrictive clothing can improve vaginal health and hygiene.
Men’s Health and Sleeping Naked
Studies indicate that tight underwear can raise testicular temperature, reducing sperm count. This directly affects male fertility, as higher temperatures decrease sperm motility and overall sperm health. Sleeping naked allows better air circulation and can support reproductive health.
Sleeping Naked and Relationship Benefits
Sharing a bed with your partner without clothing can strengthen intimacy and increase emotional closeness. Skin-to-skin contact boosts oxytocin (the "love hormone"), which reduces stress, strengthens relationships, and improves mood.
Additionally, sleeping naked helps lower cortisol levels (the stress hormone), making couples feel more relaxed and connected. The release of endorphins (happiness hormones) further contributes to stronger emotional bonds between partners.
Deeper Sleep When Sleeping Naked
Researchers at Amsterdam University found that lowering skin temperature improves sleep quality. Sleeping naked is an effective way to naturally cool down the body without adjusting room temperature.
Tight clothing and pajamas restrict movement, whereas sleeping freely allows for better sleep depth and quality.
Hygiene Tips for Sleeping Naked
- Wash bed linens more frequently – since your skin is in direct contact with sheets, they need to be cleaned often to maintain hygiene.
- Choose high-quality bedding – breathable materials like organic cotton improve sleep comfort.
- Adjust bedding according to the season – lightweight sheets for summer, warmer blankets for winter.
Fun Fact: Sleeping Naked May Aid Weight Loss
While sleeping naked alone won’t make you lose weight, it can support metabolic processes. Scientists at the National Institutes of Health found that sleeping in a cooler environment increases metabolism and helps prevent diabetes progression.
Additionally, cortisol levels play a crucial role. Overheating at night can keep cortisol levels high, which may contribute to weight gain, increased anxiety, and cravings for unhealthy food.
Who Should Avoid Sleeping Naked?
Sleeping naked may not be ideal for everyone. You should avoid it if:
✔️ You have sensitive skin – If you suffer from skin irritation or allergies, soft and breathable pajamas may protect your skin from irritants.
✔️ You sleepwalk – Sleepwalking is most common in children and teenagers, but some adults also experience it. For safety, wearing pajamas might be a better option.
✔️ Your bedroom is very cold – If your home is cold (especially during winter), wearing warm sleepwear may be a better choice than sleeping naked.
Final Thoughts
There is no universal rule about sleeping naked. Even with its scientifically proven health and sleep benefits, it ultimately comes down to personal preference. If you enjoy it—great! If not, comfort is key.
However, if you do sleep naked, remember to invest in high-quality bedding and wash your linens regularly for the best sleeping experience.
