If you want deep, quality sleep, experts say that sleeping in the nude is exactly what you need to get it.
Not only is sleeping naked more comfortable, but it has also been found to be beneficial for your health and your relationship. Without clothing, your body is able to better regulate the temperature of your skin at night, which keeps you in a deep and peaceful slumber. According to Seeker, one study found that when the skin is cooled slightly it sets the body up for a much deeper sleep.
Why is cooler skin better?
When the body decreases in temperature during sleep, it helps to release the chemicals that tell it when to sleep and when to wake up: this is its design.
Previous studies confirmed that warmer skin in both humans and animals resulted in disrupted sleep cycles and that better quality sleep was achieved in the body’s natural state. It was also found that cooler, more natural body temperatures helped to increase metabolism, boost the immune system, and activate fat loss.
According to Men’s Health, cooling down at night also reduces stress hormones and increases growth hormones, which helps your body stay lean and healthy and helps you to recover quicker from workouts. When sleep is interrupted it leads to higher levels of cortisol, the stress hormone, which results in an increase in appetite and fatigue the next day. This can lead to obesity, high cholesterol, depression, and many undesired health consequences.
How many people sleep naked? 
According to a poll from the National Sleep Foundation, only 17% of Americans sleep naked at night. As much as 52% of Americans sleep partially clothed, while 31% sleep fully clothed. Doctors are recommending a change to our sleeping habits to maximize the benefit of good rest.
Sleeping in the nude has some surprising benefits for your relationship too, helping to keep your emotional and physical bond much stronger. Experts say that skin-to-skin contact between couples at night releases oxytocin in the brain, which is known as ‘the love hormone’. This helps to cultivate a sense of trust while giving both partners a more peaceful, happy night’s sleep. It also helps to lower blood pressure and cortisol, which leads to a calmer and healthier couple.
Out of 1004 Britons, 57% of couples who slept in the nude said that they were happy in their relationships. Only 48% of those who slept in PJ’s, 43% of those who slept in nighties, and 38% of those who slept in onesies said that they were happy.
A Cotton USA poll found that the numbers are increasing, with 4 out of 10 people and more than 45% of those over 55 now sleep in the nude.
Any other health benefits?
The skin breathes better in the nude, which is ultimately important for women.
Dr. Alyssa Dweck, a clinical assistant professor at the Icahn School of Medicine in New York, says: “Women’s private parts are covered up all day by confining clothing and non-breathable fabrics, which cause vaginal irritation and moisture to collect in this area. This area can turn into a breeding ground for bacterial and yeast infections, so letting this region breathe for a few hours at night will keep bacteria at bay.”
This makes skipping the PJ’s an investment in reproductive health, not only for women, but also for men. The male scrotum is slightly cooler than the rest of the body, sitting at 95-96ºF for optimum sperm production. When the testicles become too warm, the quality of the sperm decreases, which was demonstrated in a study examining the quality of semen in regular sauna users. Sleeping naked may just be the best investment in your health and relationship yet!
