Better sleep might be as simple as cooling your bedroom.
Research shows that lowering the temperature by just two degrees can improve sleep quality by 36%.
Here’s why a cooler room works:
✔ Your core body temperature needs to drop at night to signal your brain that it’s time to sleep
✔ It helps you fall asleep faster
✔ You get deeper, more restorative sleep
✔ Heart rate variability can increase by about 7%, which is great for recovery
✔ Over time, it can even activate brown fat, helping your body burn more fat at rest
The ideal bedroom temperature is between 18 and 20 degrees Celsius.
Simple changes like dropping the thermostat or keeping a window open can make a huge difference to your sleep and overall health.
