6 healthy reasons you should sleep naked

Nixing your pajamas will improve your health and happiness—and even make you live longer. Here's how.

If you regularly sleep sans pajamas, you’re in the minority. The vast majority of us sleep swaddled in some sort of clothing — be it shorts, a tee shirt or a full-on onesie. According to a 2012 national sleep survey by Anna’s Linens, only 8 percent admit to sleeping naked.

But did you know that sleeping naked is actually great for you? Here are 6 ways nixing your pajamas will improve your health and happiness.

Reduce insomnia

As you sleep, your body naturally dips in temperature. It’s beneficial for the body to cool down, and it encourages deeper, more restful sleep. If your body is overheated, wrapped in thick socks and pants, you may not be able to release excess heat, which could rob you of a solid night’s sleep. Studies have shown that insomnia and body temperature are closely related, so take off those clothes if you’re tossing and turning.

Improve metabolism

Reduce excess belly fat by balancing cortisol levels, your stress hormone. Cortisol levels drop between 10pm and 2am, so if you’re not getting enough sleep, you may have excess amounts of stress hormones in the body upon waking that could encourage excess belly fat. Sleeping in the nude/in cooler temperatures has also been shown to lower blood sugar levels with the potential of preventing type II diabetes. Sleeping in a cooler environment encourages the body to transform regular fat into metabolism-boosting brown fat, which is responsible for temperature regulation and improved insulin sensitivity. Participants in the study saw their health improve under these conditions in a matter of weeks — so get out of those ‘jammies already!

Age more slowly

When you sleep well, your body produces melatonin and growth hormone, both of which act as anti-aging agents in the body. Since sleeping in a cool (ahem, nude) environment encourages better, deeper sleep, it isn’t a far stretch to consider that sleeping pajama-less can stave off premature aging. It also encourages healthier skin, since there are no seams or waistbands pushing in and encouraging dryness or wrinkles.

Improve relationships

Skin on skin contact with your significant other increases the amount of oxytocin your body produces. Oxytocin is a powerful hormone that increases bonding and feelings of attachment. Plus, you’re more likely to get frisky if there are no clothes standing in your way, which is also great for relationships!

Happier genitals

Exposing vaginas, naturally damp and warm places, to unobstructed air flow every night can help to reduce the growth of yeast and unwelcome bacteria. For men, testes are meant to be cooler than the rest of the body (which is why they hang outside of the body to begin with!). Testicles that are kept cooler by sleeping in the nude therefore produce healthier sperm with higher sperm counts.

Improve self-esteem

We have a tendency to hide our bodies from ourselves. But, the more you acknowledge and inhabit your beautiful body, the more likely you will be to accept it for what it truly is. In this way, sleeping in the nude can actually improve your self-esteem over time. Embrace yourself, and slide your bare skin in between those crisp sheets. It will feel so good!
