Sleeping is essential for good health, as we all know. However, according to a new study, sleeping in a colder room can improve health. Sleeping in colder rooms, can subtly transform your brown adipose tissue (considered as a good adipose) into higher consumption of energy and metabolism, even during the day.
Scientists have considered that adults do not have brown adipose, up until now. However, 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, because contrary to the well-known white adipose, it’s metabolically active. Experiments conducted on mice 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 studied the influence of controlled climate conditions in bedrooms in which 5 young men- volunteers slept for several months.The young men lived their normal lives, during the day. In the nighttime however, they slept in the Institute.All of their meals, including lunch were provided for them to guarantee proper calorie intake.They were covered with light sheets.
Researchers kept the temperature at 24°C the first month, since they considered that neutral temperature would not cause body reactions. The following 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). They restored the temperature to 24°C the next month so that all effects from the cold room were abolished. They increased the temperature to 27°C for the last month. 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.
