Your body temperature should drop by 0.5° for you to fall asleep. Sleeping naked helps heat from your core dissipate quickly from your skin, allowing you to sleep sooner. It helps calorie-burning by boosting brown fat levels, improves metabolism, prevents foul body odor, and improves sperm quality. But don’t go bare if you have with sensitive skin, declining muscle mass, or low basal metabolic rate.
Sleeping au naturel, minus a stitch of clothing, isn’t a common choice, but for the many Americans who do (12%) and many more Britons (30%), this is second nature.1 Besides nudists, a lot of mainstream people choose to sleep in the buff, simply because they find it liberating or just more comfortable. But sleeping naked has benefits too. It lets your body achieve the right temperature to sleep well, allows for better air circulation to different parts of your body, and can also improve sperm quality. Don’t believe us? Here’s proof.
You Sleep Faster And Deeper
A good night’s rest depends on more than the comfort of your bed. It is hugely influenced by the ambient temperature, the fabric of your sleepwear, and your bed linen. All of these influence your core body temperature, which in turn regulates your sleep. When you fall asleep, your core body temperature typically drops and the skin temperature goes up as heat is dissipated from your core to the outside.
Going clothing-free could possibly help the process, allowing the heat trapped in your body to escape easily into the environment. In fact, insomniacs often have a higher core body temperature than natural at bedtime because their skin doesn’t lose heat easily.
A group of researchers found that if the skin temperature is kept just 0.4°C higher, people sleep quicker, have the more slow-wave deep sleep, and don’t wake up early.
If you have exercised before sleep, shed your clothes before you drift off. This will lower the exercise-related rise in core body temperature.
If using an air conditioner or heater to keep the temperature right is not always an option, the answer could be as easy as switching what you wear (or don’t wear) to sleep. As one study found, choosing the appropriate sleepwear for the weather is important, and lower temperatures made sleep easier.
According to the National Sleep Foundation, you need to get your body temperature down by half a degree to drop off to sleep. By slipping off your sleepwear, you allow your body to experience a cooler environment and may sleep quicker and deeper.
Deep sleep has many benefits for your body – it keeps the signs of aging at bay, improves your immunity, repairs the body, and helps release growth hormone, which produces proteins and utilizes fats, among other things.
Of course, sleeping naked is not a year-round option in places with a harsh winter, for instance, unless you maintain your home at warmer temperatures.
