Sleeping in the cold can burn twice as much calories, researchers say
What winter makes us to feel an extra sleep, this is undeniable, but what we did not know is that extending the time in bed can even send a few pounds though. At least that's what researchers say at the National Institutes of Health of the United States: they claim that to keep the body warm in the cold during sleep, our body ends up speeding up the metabolism. For the study, the participants, all men, slept in temperature controlled rooms and had the same meals for four months, thus ensuring that the calories ingested by all were the same. They also received the same types of bedding and pajamas.
The tests were done in three moments, divided by the room temperature of the participants. One month should be at 18 °, another two months at 23 °, and finally one last month at 27 °. With the analysis, the researchers noted that in the weeks with the lowest temperature, the participants' body adjusted to lose more weight.
The results also show that people who slept naked, covered with a thin duvet, had more chances of losing weight. They noticed that the burning of fat capable of producing heat was twice as great. When they slept at higher temperatures, the result was just the opposite.
Brown fat, which produces 300 times more heat than any organ in the body and burns calories very quickly, is plentiful in babies, but levels drop to almost zero as people become adults.
