The Science Behind Temperature and a Good Night's Sleep

• Your body cools down naturally before sleep, and even a one-degree difference in temperature helps determine how quickly you fall asleep and how deeply you rest
• Exposing one foot from under the blanket helps your body release heat more efficiently, triggering your brain's sleep signal and promoting faster, deeper sleep
• A large study published in the Journal of Clinical Sleep Medicine found that people with steady 24-hour skin temperature rhythms enjoyed longer, more restorative sleep and better daytime alertness
• Keeping your bedroom cool, dark, and consistent with your body's natural temperature rhythm supports melatonin release and stabilizes your circadian clock
• Simple strategies — like cooling your room, using breathable bedding, and developing a nightly wind-down routine — help you fall asleep faster, stay asleep longer, and wake feeling more refreshed
