why do i get hot when i sleep

The main reasons for feeling hot when sleeping include a warm room temperature, heavy or non-breathable bedding and sleepwear, hormonal changes, certain medications, and underlying health conditions. Stress and anxiety can also raise your core body temperature at night, making you feel overheated. Additionally, late-night exercise, spicy foods, and consumption of alcohol or caffeine can increase body heat. Physiologically, the body's thermoregulation process normally lowers core temperature to facilitate sleep, but disruptions to this process can cause overheating. Sleep environments that trap heat, such as memory foam mattresses or thick blankets, can also contribute to feeling too hot during the night. Managing room temperature, choosing breathable fabrics, and reducing stress and certain triggers can help cool down nighttime body heat and improve sleep quality.
