Getting enough quality sleep becomes increasingly important as we age. Restful sleep supports overall health, improves energy levels, and helps maintain both physical and mental well-being. One often-overlooked factor that can affect sleep quality is your bedroom temperature.
According to sleep expert Dr. Kelvas, room temperature plays a significant role in how easily we fall asleep and how well we stay asleep throughout the night.
When a room is too hot or too cold, the body has to work harder to regulate its temperature, which can interfere with the natural sleep process. This may make it more difficult to fall asleep and reduce overall sleep quality. According to the Sleep Foundation, the ideal bedroom temperature for most adults is between 60°F and 68°F (15.5°C to 20°C).
How Temperature Affects Sleep
The human body has a thermoregulatory system that helps maintain a stable internal temperature. It uses several mechanisms, including sweating, shivering, and changes in blood flow, to stay within a healthy temperature range.
Body temperature naturally changes throughout the day. In the evening, your core body temperature begins to drop, signaling that it is time to sleep. This decrease helps promote slow-wave (deep) sleep, an important stage for physical recovery and overall health.
A bedroom that is too warm can make it harder to fall asleep and may reduce the amount of deep sleep and REM (rapid eye movement) sleep you get. High humidity can also make sleep less comfortable by reducing the body’s ability to cool itself efficiently.
