Isn't internal body temperature kept constant (or at least the body tries very hard to) irrespective of environment?
- tim333 8y agoThe body tries to keep the core temperature constant around the heart and internal organs and will divert blood there and let your feet get cold. I'm not sure about the brain but in a 40C climate say I doubt your head would get cold inside.
- whatsstolat 8y agoI'm not sure anywhere on earth is 40c at night.
- gpvos 8y agoDepends on where you are. In a land climate, days can be searing hot while nights are freezing cold.
- CydeWeys 8y agoThere's plenty of places in the tropics where it's hot during the day and night for months on end, and yet as far as I know there's no evidence of less REM sleep in the people living there. And even if there weren't, these conditions would be easy to replicate in a laboratory.
