Room Temperature

Sleeping in a cooler room significantly improves both sleep depth and duration. A room temperature of approximately 68°F (20°C) is the recommended sleep environment. A bedroom temperature of approximately 68°F (20°C) is recommended for quality sleep. Deep sleep requires a core body temperature drop, which an overly warm room prevents. Rooms that are too warm prevent the body from entering deep sleep stages. A hotter sleeping environment impairs sleep.
