A room that’s too hot or cold can disrupt your body’s ability to regulate sleep hormones like melatonin, making it harder to fall or stay asleep. Experts recommend keeping your bedroom between **60–68 °F (15.5–20 °C)** for optimal rest.

### **How Temperature Affects the Body**
– **Cooling down:** Your core body temp drops before sleep. A cool room supports this natural process, helping you fall asleep faster.
– **Warming up:** When it’s too cold, your body burns energy to stay warm, which can disturb deep sleep.
– **Sweating and shivering:** Help regulate internal temperature during the night.
– **Feet matter:** Wearing socks can help if you’re cold; sticking feet out of the blanket helps cool down if you’re too warm.

### **Temperature & Sleep Stages**
– A cooler room improves **REM** and **slow-wave sleep**—both essential for memory, recovery, and hormone regulation.
– Too much heat can cause night sweats, restlessness, and reduced sleep quality.
– Humidity can also interfere with thermoregulation and sleep depth.

### **Benefits of a Cool Room**
1. **Better Sleep Quality**: More time in deep and REM sleep, fewer night wakings.
2. **Faster Sleep Onset**: Helps the body cool down naturally and fall asleep quicker.
3. **Weight Management**: Cool temps activate brown fat, which burns more calories.
4. **Lower Disease Risk**: Supports insulin sensitivity, brain detox, and may help prevent conditions like diabetes and Alzheimer’s.

Keeping your room cool isn’t just about comfort—it’s vital for your sleep and overall health.
