What Is the Best Bedroom Temperature for Sleep?
Temperature plays a crucial role in how well you sleep. Whether you’re dealing with a summer heat wave or a chilly winter night, the temperature of your bedroom can make a significant difference in your sleep quality. Fortunately, there are several strategies you can use to create the ideal sleep environment, from adjusting your thermostat to choosing the right bedding and pajamas. Finding your comfort zone can help you achieve a restful night’s sleep.
Why Bedroom Temperature Matters for Sleep
Your body’s core temperature naturally drops as you prepare for REM sleep. Lowering your bedroom temperature can support this process and help you fall asleep faster. While preferences vary, most adults sleep best when the bedroom temperature is between 60 and 67 degrees Fahrenheit.
Effects of Temperature on Sleep Quality
- Too Warm: When your room is too hot, your body must work harder to cool down. This can delay sleep onset, cause night sweats, and disrupt melatonin production, all of which reduce sleep quality and interfere with restful REM cycles.
- Too Cold: If your bedroom is too cold, your body expends energy to stay warm, making it harder to fall asleep and maintain deep, restorative sleep. This can impact both bodily recovery and brain health.
Research on Optimal Bedroom Temperature
Studies in 2026 continue to confirm that keeping your sleeping environment within an optimal temperature range is one of the most effective ways to improve sleep quality. Temperature regulation is considered a fundamental sleep hygiene practice, along with maintaining a regular bedtime routine and avoiding caffeine or spicy foods before bed.
Common Causes of Overheating at Night
- Hot or heavy bedding
- Poor air circulation
- Overactive sweat glands
- High room humidity
Research shows that overheating during sleep can lead to more frequent awakenings, longer time to fall asleep, and reduced overall sleep quality.
Tips for Maintaining the Best Bedroom Temperature
- Use a fan or open windows to improve air circulation and keep the room cool.
- Wear loose, breathable pajamas and choose lightweight, moisture-wicking bedding.
- Consider a dehumidifier to lower humidity, but avoid overuse as it may affect respiratory health. Learn more about using dehumidifiers.
- If you continue to have trouble sleeping, consult your physician for additional support. Find more sleep advice here.

- Avoid caffeine and spicy foods in the evening.
- Choose bedding and pajamas that promote airflow and comfort. Explore bedding options.
