Benefits of Sleeping Naked

Potentially Improved Sleep

Our bodies are regulated by our circadian rhythm, which cycles through heating and cooling patterns throughout the day. As we begin to feel tired at the end of the day, our melatonin production increases and our core body temperature decreases. This decrease in body temperature continues throughout the night.

The optimal room temperature for sleep ranges from around 66 to 70 degrees Fahrenheit and is key to sleeping well. Becoming too warm at night interferes with sleep. For this reason, some people believe sleeping nude can help your body achieve a cooler core temperature faster and promote better sleep. Researchers haven’t directly studied the effect sleeping nude has on sleep, however.

If you decide to try sleeping naked, make sure you have comfortable bedding. Like heat, cold can also negatively affect sleep quality. Researchers found that those who slept semi-nude were more susceptible Trusted Source National Center for Biotechnology Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

“Keeping cool at night is a simple way to improve sleep quality. For those who prefer to sleep with a thick and warm comforter, sleeping naked is a good way to counterbalance that extra warmth.”

Vaginal Health

Sleeping naked may help keep Candida yeast from flourishing in the vagina.

The risk of yeast infections is often increased by inadequate air circulation Trusted Source Merck Manual First published in 1899 as a small reference book for physicians and pharmacists, the Manual grew in size and scope to become one of the most widely used comprehensive medical resources for professionals and consumers.

Skin Health

Sleep can impact your skin’s health and appearance. When you are fatigued and not getting enough sleep, your skin is more susceptible to wrinkles, drooping, swelling, and dark circles under your eyes. Delayed or reduced sleep also impacts your skin’s ability to heal wounds, like cuts or blisters.

If sleeping naked helps you sleep better, then it will also improve the health of your skin. More sleep gives your skin time to regenerate and repair any wounds, helping you look and feel your best. That said, no studies have been conducted yet on how sleeping nude affects skin.

Male Fertility

Sleeping naked can help you keep your body temperature cooler. Although research on sleeping naked is needed to draw valid conclusions, past research suggests the cooling associated with sleeping nude might increase sperm health.

Relationships and Self-Esteem
