You Sleep During the Night in a Cold Room? Here is What can Happen to You!

Sleeping is essential for good health, as we all know. But, a new study has shown that sleeping in a colder room can improve health. Colder sleeping rooms can subtly transform your brown adipose tissue (considered as a good adipose) into higher consumption of energy and metabolism, even during the day.

Until recently, scientists have considered that adults do not have brown adipose, but during the last couple of years, a very small amount in the size of a teaspoon, has been found in the neck and the upper part of the back in many adults. This is a very important brown adipose, and contrary to the well known white adipose, it is metabolically active. Mice experiments have shown that sugar needs to be out of the bloodstream so that calories can be burnt and inside temperature of the body is maintained.

Apparently, a similar process occurs in people, as well. A new study, published by the American Diabetes Association in July, in collaboration with the National Institute for Health, has researched the influence of controlled climate conditions in bedrooms in which 5 young men- volunteers slept for several months. During the day, the young men lived their normal lives, but it the nighttime they slept in the Institute. All meals, including lunch were provided for them so that proper intake of calories is guaranteed. They were covered with light sheets.

During the first month, researchers have kept a temperature of 24°C, since they considered that neutral temperature would not cause body reactions. The next month, they lowered the temperature to 19°C, which they considered that it would stimulate, in smaller amounts, the brown adipose tissue (but it will not cause trembling, which is a usual reaction of lower temperatures). The next month, the temperature was restored to 24°C so that all effects from the cold room were abolished. At the end of the last month they increased the temperature to 27°C.  Blood sugar, insulin level and intake of calories were tracked during the experiment, and also after each month, the amount of brown adipose was measured.
