Answer :
False :) Sleeping in a colder room is good for your health. When it's cold and your body is trying to regulate itself, you'll sleep better.
The statement is False.
It is said that optimal temperature for sleep is around 60-67 degrees Fahrenheit. It is recommended to keep a cool room temperature than a warm one. This is related to the concept of thermoregulation, which is a human’s ability to manage her or his body temperature despite the changing temperature of its surrounding. It is better to sleep in a cool room, because our body prefers it that way.
