9 Reasons Why You Should Be Sleeping Naked, According to Science

We all know how important sleep is for our overall health and well-being. After all, nothing feels better than waking up refreshed after a good night’s sleep. However, have you ever considered the idea of sleeping naked? While not everyone may be comfortable with the idea, there are actually several benefits to sleeping in your birthday suit. Let’s explore why you might want to consider sleeping au natural – according to science.

The Importance of Sleep

Before we dive into the benefits of sleeping naked, let’s first discuss the importance of sleep in general. Adequate sleep has been linked to a lower risk of diabetes, heart disease, high blood pressure, and much more. The American Academy of Sleep Medicine recommends seven to nine hours a night for adults. According to their findings, consistently getting less than six hours per night can lead to an increased mortality rate by 15% or more. (1, 2) Maintaining a good night’s sleep will also help you manage your weight. The reason for this is that sleep helps to regulate hormones and blood sugar levels. When we get enough sleep, our bodies are able to function properly without relying on extra energy stores. This means you’ll have more energy throughout the day and be less likely to overeat. (3)

On the other hand, poor sleep has been linked to depression and even an increased risk of self-harm

The recommended amount of sleep for adults is 7-9 hours per night. Sleep is not just a way to rest your body and mind but also to reset your circadian rhythm. This helps you manage stress and feel more balanced throughout the day. (4) If you’re feeling like sleep is the last thing on your mind, and you need the motivation to get it done, we have some tips you can try.

Now that we understand sleep’s importance, let’s explore the benefits of sleeping naked. Here are nine reasons why you should consider ditching your pajamas:

1. Improved Sleep Quality

As already mentioned, one factor that influences sleep quality is the room’s temperature. If you are too warm, you won’t sleep well. Sleeping naked can help regulate your body temperature, leading to deeper and more restful sleep. (5)

2. Skin-to-skin contact

If you sleep with a partner, then sleeping naked can actually benefit your relationship and your health. Skin-to-skin contact with your partner can release oxytocin, the “love hormone,” which can reduce stress and anxiety. Not only will this benefit your relationship, but it will ultimately help you to sleep better. (6)

3. Better for Your Lady Parts

Sleeping without underwear can reduce the risk of yeast infections and other vaginal irritations for women. This is because bacteria that cause yeast infection prefer a warm, moist environment. Sleeping naked allows you to “air out” your nether regions, if you will, and discourage bacteria from overgrowing. (7)

4. Improved Sperm Quality

Research shows that wearing tight-fitting underwear can affect sperm count. For men, sleeping naked can help regulate testicular temperature, leading to improved sperm quality. It also gives your parts a chance to be free of the confines of underwear for (ideally) seven to nine hours each night. (8)

5. Better for Your Skin

Sleeping naked can help your skin breathe and reduce the risk of skin irritations. Also, because sleeping naked can actually help you to sleep better, it promotes skin health and repair. Sleeping well promotes wound healing, and your skin looks fresh and rested each day. (9)

6. Reduced Stress and Anxiety

We’ve already mentioned that getting a good night’s sleep decreases stress and improves mental health. Sleeping naked promotes a better night’s sleep – you only have to lose the PJs! (10)

7. Prevent Weight Gain

A study that followed over 21,000 people for three years and found a possible link between inadequate sleep and weight gain. The results show that getting less than 5 hours each night can make you more likely to pack on the extra pounds. Sleeping naked keeps your body cooler and helps you sleep better, for longer. Another smaller study found that keeping your body cooler at night helps to burn more calories while you sleep. (11, 12)

8. May Lower Risk of Heart Disease and Type 2 Diabetes

A study published in 2010 followed 1,455 people over six years and found an association between lower sleep duration and increased risk of diabetes. This, in turn, increases your risk of developing heart disease. Sleeping naked helps you fall asleep, stay asleep, and get higher quality sleep, again largely due to body temperature regulation. (13)

9. Fall asleep faster

We have all had those nights when we lie there, staring at the ceiling, wondering when sleep will finally come. Again, sleeping in the nude helps to keep you cooler, which can help you fall asleep faster. When your body wants to sleep, as part of your circadian rhythm, your body lowers its temperature. This signals that it is time for sleep. Keep yourself cooler by taking off the unnecessary layer of clothing, and you can get to dreamland faster.

Getting adequate quality sleep is the ultimate goal; sleeping naked can help you get there. However, we understand that not everyone may be comfortable sleeping this way. If you’re not used to sleeping naked, start by taking off one layer at a time and ease into it. At the very least, sleeping in light, loose-fitting pajamas instead of a tight top or fitted underwear will go a long way. At the end of the day, the most important thing is getting the sleep your body needs to function at its best.
