Quick answer: The ideal bedroom temperature for sleep is around 60–67 °F (15–19 °C). A cooler room helps your core body temperature drop, which signals your brain it’s time to sleep and supports deeper rest. If you run hot, cooling bedding or a fan helps more than just cranking the thermostat.
Why cooler is better
Falling asleep depends on your core temperature dropping. A warm room fights that process, leading to restlessness and lighter sleep; a cool room works with your biology.
The sweet spot
Most sleep research points to 60–67 °F. Within that, pick what feels comfortable — too cold is as disruptive as too warm.
How to get there
Breathable bedding, good airflow or a fan, and a warm shower an hour before bed (which then drops your temperature) all help you hit the zone. General wellness information, not medical advice.
