The cold temperature helps lose weight, says Harvard scientists.

Harvard scientists discovered how cold temperatures can help to lose weight. Cold temperature increases metabolism and also makes training more comfortable. Losing weight is based on the idea that the body uses more energy than it gets. The cold temperature increases the metabolism of the cells because the body must be warm. 

And otherwise saying low temperatures increase energy use because the body needs more energy to keep its temperature stable. And the idea of loss of weight is that.  The energy use of the body will increase. 

Cold temperature decreases sweating. And that thing makes training like running or gym more comfortable. The idea is that the low temperature is one of the things that help to lose weight. 

So, the person needs more energy than previously. Because the temperature in the body doesn't rise so much. The person can train for longer periods than before. And that makes training more effective. The benefit of the low temperature is also that metabolism of the bacteria is slower. 

That decreases their ability to create poisons and descendants. That means in the room are fewer bacteria and fungi if the temperature is lower than in the warm room.  That keeps the room space more hygienic than the high temperature which makes breathing easier. So low temperature has lots of benefits, from the point of view of heath.
