Core body temperature naturally drops at night to initiate sleep. A cool room supports this process.
Cooler temps help you fall asleep faster and spend more time in deep, restorative sleep .
Deep sleep regulates hormones like cortisol (stress) and leptin (appetite) — reducing cravings and stress-related weight gain.
Experts from the National Sleep Foundation recommend a bedroom temperature between 60–67°F (15.5–19.4°C) — the sweet spot for optimal rest and metabolic function.
How to Use This Trick Tonight
Ready to burn more calories and sleep better? Try these simple steps:
✅ Set your thermostat to 60–67°F (15.5–19.4°C)
Start at 67°F and gradually go cooler to see what feels best.
✅ Ditch the heavy blankets
Use lighter bedding so your body can cool down naturally.
✅ Wear light pajamas or sleep in the buff
Let your skin breathe to support natural temperature regulation.
✅ Open a window (if safe)
Fresh, cool air can enhance the effect — just avoid drafts.
✅ Avoid alcohol before bed
It may make you feel warm but disrupts your body’s ability to regulate temperature.
