Research also shows your sweat rate increases during deep sleep compared to other sleep stages. During REM, on the other hand, your body's sweat rate decreases and sweating is actually delayed, making you much more sensitive to heat as your body can't regulate its temperature as well.
Skin vasodilatation and sweating in response to a warm environment are, thus, decreased in REM sleep (Kobayashi et al., 2003; Sagot et al., 1987).
