In winter we prefer to wear many clothes, not only when we go home, but also when we go to sleep!
The latter, according to several surveys, needs to be changed, as there are plenty of reasons that prompt us to sleep naked.
One of them is that because the temperature of the body falls, our sleep becomes deeper, so we gain more energy.
Another research in Australia suggests that the fall in temperature helps to bring real sleep and rest faster!
Finally, the cold environment helps to lose fat, and boost our metabolism, as well.
Do you still sleep in your pyjamas?
