Set bedroom temperature to 60-67 degrees F

What to Do

Keep your bedroom between 60-67°F (15.5-19.5°C). Use a programmable thermostat, fan, or open window to maintain this range throughout the night.

Why It Works

Core body temperature must drop 1-3°F to initiate and maintain sleep. A cool room facilitates this natural thermoregulatory process. Sleep efficiency decreases measurably when ambient temperature exceeds 75°F, causing more awakenings and less time in deep sleep.

Tips

• 65°F (18.3°C) is the most commonly cited optimal target
• Wearing socks paradoxically helps by promoting vasodilation and faster core cooling
• If air conditioning is unavailable, a simple fan pointed at the bed surface provides meaningful cooling
• Seasonal bedding adjustments (lighter covers in summer) are often overlooked
