To get better sleep, it’s really important to have the right temperature in your room. Dr. Kelvas says that if your room is too hot or too cold, it can mess with your hormones, which makes it hard to sleep well. The Sleep Foundation suggests keeping your room temperature between 60 °F (15.5 °C) and 68 °F (20 °C) to help your body stay comfortable while you sleep.
Temperature is really important for how we sleep. Around two hours before we go to bed, our body temperature begins to lower, which tells us it’s time to sleep. Dr. Valerie Cacho explains that having a cool room can boost the production of melatonin, the hormone that helps us fall asleep. However, if the room is too warm, it can hurt our REM sleep, where we dream, and slow-wave sleep (SWS), which is essential for our bodies to recover, by making us wake up more often and interrupting our sleep.
