It’s another summer day—and there’s no end in sight from scorching temperatures. Even with the air conditioning on blast, sometimes it’s not enough to beat the heat—especially when it comes to sleep. Your body temperature is intertwined with sleep. In fact, you are the drowsiest as your body temperature falls. This process corresponds with your brain and circadian rhythm—the 24-hour clock that determines when you’re most likely to be awake and asleep. Your body temperature control is different when you’re in REM sleep. When you go through a REM cycle, you have less regulation of your body temperature, which may explain why some people might get sweatier or hotter while sleeping. Getting a good night’s rest starts with the right combination: a cool room and a warm blanket. If the room is too hot, or if your body’s too hot, that could interfere with falling asleep or staying asleep You need to be relaxed and receptive to falling asleep. If you’re uncomfortable—whether that’s too hot, too cold, itchy, or hungry—all those things can interfere with your ability to relax and let sleep happen Avoid taking a hot shower or bath right before bed: Instead, take a shower or bath about two hours before bed to help you feel drowsier. Draw the curtains: Keeping the sunlight out helps keep the room cool—and it creates a dark and relaxing sleep environment. Avoid exercising right before bed: It may take some time to get your body temperature down after a workout on a hot, summer day. Moving your workout earlier in the day can help you get better rest at night.
