english: Your body needs to drop its core temperature by about two to three degrees Fahrenheit to initiate sleep and then to stay asleep, and it's the reason you will always find it easier to fall asleep in a room that's too cold than too hot.
non_english: Telo treba da spusti temperaturu za oko jedan ili dva stepena Celzijusa da bi se utonulo u san i da bi se san održao, i iz tog razloga će vam uvek biti lakše da zaspite u sobi koja je previše hladna nego u onoj koja je previše topla.
