Updated in December 2023

Sleeping naked has several health benefits like improving your sleep quality, stimulating calorie burning, preventing weight gain, preventing yeast infections in women, increasing fertility in men, and even improving a couple's intimacy and connection.

Sleeping naked can help you to replenish energy levels, regulate various bodily functions and maintain optimal hormonal production, as well as eliminate toxins or reduce inflammation. 

If you are not used to sleeping naked, you can start by sleeping in just a t-shirt or underwear. This will help the body get used to changes in body temperature during the night until you feel totally comfortable enough to sleep naked. When sleeping naked, it also important to have comfortable bedding and enough blankets as necessary.

Health benefits

The main benefits of sleeping naked are:

1. Improve sleep quality

To achieve an optimal sleep, the body needs to reduce its core temperature by about half a degree and maintain this temperature throughout the night. Sleeping without clothes facilitates this bodily function and can therefore keep you asleep longer and in deeper phases of sleep. This is helpful for obtaining a restful night's sleep.

This especially ideal during hotter times of the year, as maintaining a colder body temperature will also help you to fall asleep faster.

2. Stimulate calorie burning

Sleeping naked in a colder environment, activates brown fat, which is a good type of fat that helps to keep the body warm, Brown fat that is activated stimulates continuous calorie burning during the day. 

Although this type fat burning alone is not enough to achieve noticeable weight loss, it can be beneficial when combined with a weight loss diet. 

3. Prevent weight gain

Sleeping naked helps you fall asleep faster and improve your sleep quality, which are both factors in preventing weight gain.

Some studies have shown that not getting enough sleep can negatively impact hormone production, leading to lower leptin levels and higher ghrelin levels. These hormones are related to appetite, satiety and hunger.

4. Combat diabetes

When brown fat is active, in addition to burning calories, the body also becomes more sensitive to insulin. This hormone is important for regulating sugar levels and ensuring it does not accumulate in the blood. Therefore, a colder body temperature can play a role in regulating blood sugar levels, preventing the onset of diabetes.

5. Reduce blood pressure

According to several studies, lying naked next to another person and skin-to-skin contact stimulates the body to produce more oxytocin.

This hormone is capable of keeping blood pressure normal, which is optimal for heart health, as well as strengthening the immune system and combating anxiety.

6. Prevent yeast infections

Sleeping naked helps prevent the onset or worsening of yeast infections, especially in women. It helps to keep the genital area less humid and air-dry,  making it difficult for fungus that causes yeast infections (Candida albicans), to multiply and spread. Check-out other home remedies for yeast infections that you can use to help treat and prevent this condition.

7. Prevent skin infections

Sleeping naked also reduces the probability of sweat and moisture from accumulating, particularly between the fingers, toes and groin. Dry skin conditions are beneficial for preventing the growth and spread of different types of fungi which can lead to athlete's foot or groin ringworm.

8. Increase male fertility

Some studies suggest that sleeping naked can increase male fertility, as sleeping in tight clothing increases the temperature of the testicles, which can lead to lower sperm levels

Therefore, sleeping naked can help the testicles to maintain a lower temperature, which can increase sperm production and male fertility.

9. Improve sex life and intimacy

Sleeping naked with your partner can contribute to an increased desire to engage in intimate contact more frequently, which also helps to reduce stress and anxiety, and improve the couple's relationship.

Furthermore, skin-to-skin contact with your partner stimulates the body's production of oxytocin, which helps to improve libido and sexual performance, pleasure sensations, intimate relationships and affection. In men, it can help to better erections and ejaculation.

10. Reduce stress and anxiety

Stress and anxiety are cyclically linked to insomnia and poor sleep quality. Each of these can negatively affect quality of life.

Therefore, sleeping naked can help improve sleep quality and regulate cortisol levels, which can help reduce stress and anxiety.
