If you’ve ever woken up tossing off blankets in a sweat or pulling them back when shivering, you already know how much temperature can affect your sleep. The body’s ability to cool down and stay regulated at night is directly tied to sleep quality — and the wrong environment can leave you restless, groggy, and unrefreshed the next day.
So, what is the best temperature for sleep, and how can you set up your bed to help?
The Science Behind Sleep Temperature
When you fall asleep, your body temperature naturally drops by one to two degrees as part of its circadian rhythm. This cooling signals your brain that it’s time for rest. If your bedroom is too warm or too cold, this process is disrupted, making it harder to reach deep, restorative stages of sleep.
- Too hot: Overheating can cause frequent awakenings, sweating, and difficulty entering deep sleep.
- Too cold: Being chilled forces the body to work harder to maintain core temperature, leading to discomfort and fragmented sleep.
- Just right: Studies suggest the optimal sleep temperature is around 60–67°F (15–19°C) for most adults.
Why Bedding and Mattresses Matter
Even if your thermostat is set correctly, your sleep surface plays a big role in thermal regulation:
- Mattress materials: Foam mattresses often trap heat, while organic latex allows better airflow and resists heat buildup.
- Toppers: A breathable latex topper adds comfort and temperature balance without locking in warmth.
- Bedding: Natural fibers like organic cotton wick away moisture and help regulate body heat, keeping you comfortable in all seasons.
Tips for Sleeping Cooler (Or Warmer) At Night
- Keep your bedroom cool, between 60–67°F.
- Layer breathable bedding you can adjust easily through the night.
- Use an air purifier or fan for better airflow (bonus: white noise for deeper rest).
- Choose pajamas made from cotton, bamboo, or other breathable fabrics instead of synthetics.
- For cold nights, opt for a lightweight wool blanket. It insulates without trapping too much heat.
Finding your “just right” temperature is easier when your sleep surface works with your body instead of against it. At My Green Mattress, every mattress is made with organic latex, cotton, and wool — materials that are naturally breathable, moisture-wicking, and temperature-regulating. Paired with an organic cotton protector and lightweight organic sheets, you’ll create a sleep environment that helps you stay comfortable all night long.
