Fan your bedroom and mind with a cool, calm environment
Your core body temperature naturally falls at night, signaling tissues to repair, hormones to replenish, and the deepest sleep cycles to begin. Keep your room too warm and you’re forcing your body to run uphill on its own thermostat—a recipe for wakeful tossing and groggy mornings.
Scientists have linked cooler bedroom environments to less wakefulness and up to 75 percent more time in deep, delta-wave sleep. Lower temperatures help your skin moderate heat loss, dilate blood vessels and move warm blood away from your core. That gentle evening cooldown matches your circadian drop and encourages regenerative rest.
When the thermostat hangs above 70 °F, your system may spend its nights in futile efforts to turn down internal heat. By customizing your environment with breathable linens, a fan or a slight open-window breeze, you respect your physiology—unlocking lower stress, improved immunity and more refreshing days. Don’t sweat your sleep; cool it.
This evening reset your bedroom to 65 °F and swap your heavy covers for lighter sheets. Take a warm bath about 90 minutes before bed—notice how your skin cools afterward—and slide into breathable sleepwear. Experience the calm return of quality deep sleep when you make cool your bedroom’s new normal.
What You'll Achieve
By optimizing your nightly thermal environment, you’ll accelerate the body’s renewal systems, reduce night wakings, and wake up less stiff, less inflamed and more energized.
Turn down the thermostat for better rest
Set bedroom temperature to 60–68°F
Use a smart thermostat or simple wall dial to keep nights cooler. A 5–10°F drop from daytime settings signals your body to begin its temperature-lowering process and slip into deep, healing sleep.
Create a bedtime cooling routine
Try a warm bath 1½ hours before bed to trigger a subsequent core temperature drop. Follow with lightweight pajamas or no socks, and let your body thermoregulate naturally as you drift off.
Use cooling sleep accessories
Consider a breathable mattress pad or moisture-wicking sheets made of bamboo or linen. These surfaces help draw heat away and prevent nighttime overheating.
