As we age, prioritizing sleep becomes essential for maintaining health and energy. Dr. Kelvas, a sleep expert, highlights the impact of room temperature on our ability to fall and stay asleep. The optimal temperature for quality sleep ranges between 60°F (15.5°C) and 68°F (20°C). Temperature plays a crucial role in regulating the body’s sleep cycle. A cooler room encourages melatonin production, helping us fall asleep faster and spend more time in deep sleep phases like REM. It also supports brown fat activation, which boosts metabolism and lowers the risk of conditions such as type 2 diabetes and Alzheimer’s. Even without a thermostat, you can enhance your sleep by taking a warm bath before bed, which helps lower your internal temperature.
