For many of us, putting on our pyjamas is an essential part of our bedtime routine, but new studies suggest that sleeping naked may be good for you in a number of ways. One of the more famous fans of this sleeping style was the iconic Marilyn Monroe, but will you be ditching the PJ's and following in this sultry sirens footsteps? Let's take a look at some of the benefits of going nude and how it may help your quality of sleep.
The most commonly cited benefit of sleeping naked is the increased quality of sleep you can achieve. One study found that temperature regulation, specifically overheating, is one reason why many of us have restless nights. By forgoing pyjamas the body can cool down quicker and regulate itself to the lower body temperature your brain requires for a good night's sleep. This natural decline in temperature is caused by the body's circadian rhythm and sleeping in pyjamas can disrupt this natural cooling of your core temperature, and therefore interrupt your sleep cycle. Our sleep expert, Dr Nerina Ramlakhan, also suggest that the ideal temperature for a good sleep is "slightly cool"- so another good reason to take the plunge!
Sleeping in the buff may also be good for those of us looking to shed a few pounds. A 2014 study found that there is a link between an increased metabolism and cooler nighttime temperatures. By sleeping naked, or in a cooler room, your body produces almost double the amount of 'brown' fat - a healthy fat that the body burns to maintain your core temperature - compared to the amount produced when sleeping in a warmer environment. Researchers at the University of Warwick also found that those of us who regularly get less than six hours of sleep are three times more likely to develop diabetes and heart disease, both of which can lead to unwanted weight gain. As sleeping naked can impact the amount of deep sleep we get, it can aid some people in reducing the risks of developing these diseases.
Wearing your birthday suit to bed may also be good for your stress levels. Sleeping naked promotes better quality of sleep, and this in turn lowers your body's cortisol levels, the so-called "stress hormone". As we know, stress levels and sleep go hand in hand, meaning that anything we can do to help each of these is a beneficial for everyone in the long run.
It's not all about physical health benefits though. Sleeping
naked may also be good for your relationship. According to a survey
by Cotton USA, sleeping together naked can lead to happier
relationships. Skin-on-skin contact is also a major factor in this,
as it triggers the brain to produce oxytocin, a chemical which
reduces stress and promotes an increased feeling of connection with
With all of the above in mind, will you be ditching the pyjamas and trying out a nude nights sleep?
