Listen, we love some nice pajamas as much as the next. Don’t even get us started about footie pajamas! But it turns out there are tons of benefits to sleeping in the nude. These include aspects of your health, relationship, appearance, and overall mood. Feel free to take baby steps by starting out with wearing just underwear or just a big shirt. If you’re a free bird, slip into your birthday suit tonight before bed, and see if you notice any of the many benefits.

Leave all your clothes on the floor, it’s good for your health.

Sleeping Naked Helps You Sleep Better

And we could all use a better night’s sleep. The reason behind this is that your body temperature while you sleep is around 96℉, which is two degrees lower than your normal body temperature during the day. Because sleeping in pajamas keeps you warm, it can actually interfere with your body’s ability to drop in temperature in preparation for sleep. If you’re too warm during the night, you’re more likely to wake up sporadically or not be able to get into deep sleep. Also, the fabric of your pajamas can pull on, restrict, or irritate your skin. Sleeping naked, on the other hand, can give one a sense of being free, and can be more comfortable.

Sleeping Naked Can Burn More Calories

Like we talked about above, sleeping naked usually means sleeping cooler, and sleeping cooler can boost metabolism and aid in weight loss. This 2014 National Institute of Health study concluded that sleeping in colder temperatures increases your body’s amount of brown fat, which “burns chemical energy to create heat and help maintain body temperature.” In the study, those that slept in 66° rooms for a month had an increase in brown fat and improved insulin sensitivity. Prolonged exposure to the mild cold also showed significant changes in metabolic hormones like leptin (the energy expenditure hormone) and adiponectin (regulates glucose and fatty acid breakdown). Basically, humans can acclimate to cool temperatures by increasing their brown fat, “which in turn may lead to improvements in glucose metabolism. These changes can be dampened or reversed following exposure to warmer temperatures, though.”

Sleeping Naked Can Reverse Aging

That’s right folks, sleep naked and you’ll wake up as an 18 year old again. Just kidding, but it can help you to look younger. As your body temperature drops while you sleep, your body releases the hormones melatonin and human growth hormone, which can help you to look more rested and youthful. Melatonin works to produce antioxidants that curb free radicals, which are the molecules that cause skin aging. Also, according to this article, human growth hormone can “can reduce wrinkles, tighten saggy skin, decrease body fat, increase lean muscle mass, boost energy,” and more. Now that’s some good beauty sleep.

Sleeping Naked Can Boost Your Mood In The Morning

All signs point to sleeping naked leading to a better night’s sleep. When you sleep better, you perform better during the day. This includes improvements in overall mood, cognitive abilities, decision making, and ability to handle stress. Sleeping naked also creates a sense of comfort and assurance in a lot of people. Even when sleeping alone, sleeping naked can help you become more comfortable in your own skin.

Sweet dreams!

Also, if you sleep next to a partner at night, having more skin-to-skin contact produces more Oxytocin. Oxytocin is nicknamed the love drug. It promotes quality and quantity of orgasms, reduces blood pressure, and can help with anxiety. Who isn’t happier the next day (and the following days) with more of that?

Sleeping Naked Is Good For Your Body

Specifically, your reproductive body parts. When you don’t have any underwear on, air can circulate better around your private areas. This reduces moisture and heat that tends to accumulate in these areas, which, if left to build, can lead to yeast and fungus that causes jock itch and yeast infections. You could even get away with wearing a big flowy shirt, and then go sans panties to still get these benefits.

Also, according to a study by the National Institute of Child Health and Development and Stanford University, men who wear boxers during the day but go nude at bedtime have 25 percent better sperm count from the lack of restriction in their sleep. Is that reason enough to hop into bed naked and get to… sleeping?
