The temperature of bedrooms in Swiss households
Experts recommend a temperature of between 14 and 18 degrees Celsius as the optimum sleeping temperature to support the body's sleep cycle. The body can slightly reduce its core temperature within this temperature range, promoting deep and restful sleep. A temperature that is too high can precipitate restlessness and disrupt the REM sleep cycle, while a temperature that is too low can also be uncomfortable. Furthermore, a more relaxed environment facilitates the release of melatonin, a hormone that regulates the sleep-wake cycle. Maintaining an optimal room temperature can facilitate improved sleep quality and enhance the ease of falling asleep.
