Why actually have to sleep in a cool room

Scientists have found that sleep at cool temperature positively affects the body and improves metabolism.

In the body there are two kinds of fat: white and brown. White - the supply of calories. A brown provides heat generation. Brown adipose tissue developed in newborns. It helps them to keep warm, but with age, we lose most of these tissues.

Unlike white fat, which stores a supply of calories, brown fat helps burn calories.

Researchers from the US National Institutes of Health have found that it is possible to raise the level brown fat in the body, if you sleep in a cool roomTemperature-acclimated brown adipose tissue modulates insulin sensitivity in humans..

Scientists conducted an experiment: five healthy participants within four months sleeping in a temperature-controlled. The number of calories consumed by them are also taken into account. The neutral temperature was maintained to 24 ° C during the first month during sleep. The next month it was reduced to 19 ° C, then re-raised to neutral. And last month the temperature was raised to 27 ° C.

It was found that cool temperature significantly affects the body. Just a month sleeping in a cool room reserves of brown fat in the body of participants almost doubled. And this in turn has improved their sensitivity to insulin. This characteristic indicates how well the body metabolizes glucose. At a reduced sensitivity to insulin increases the risk of developing diabetes.

Also this month, participants burned more calories throughout the day. But as soon as they began to sleep again at elevated temperature, the changes have come to naught. The content of the brown fatty tissue back to the same elevation as before the experiment.

This is great news. After all, it turns out to restart your metabolism, simply to sleep in a cool room.
