It’s a well known fact that sauna use promotes a deep, restful sleep. A few minutes relaxing in the soothing heat raises core body temperature, which drops upon exiting. With the temperature drop, the body signals the brain to rest, making the transition from awake to sleep easier.
It has to do with the slow decline in endorphins, which facilitates sleep. Sauna bathers worldwide agree that using a sauna before bed results in a more restful, more relaxing sleep.
