According to many sleep experts, 62% of American bedrooms have at least one sleeper who runs hot. It's a common issue that is due to many factors, including the type of mattress you have, room temperature, bedding and sleepwear fabrics, your partner's sleeping habits, and how close to bedtime you exercise or eat. Whether you experience any or all of these factors, the latest mattress innovations can help you reach the "Goldilocks state" – that "just right" sleep temperature. If you're having trouble achieving "just right," it may be time to invest in a mattress that's specially designed to cool your body down, not just when you get into bed, but throughout the night, so you wake up feeling totally rested and refreshed. Ideally, cool, dark and quiet are the three magic room factors that promote a better night's sleep. And, naturally, a "just right" mattress. Optimal Body Temperature || Just as your car reacts unfavorably when it overheats, the same is true of your body. This, in turn, can adversely affect your sleep, causing you to toss and turn. Experts have determined the best bedroom temperature for most adults is between 60 and 72 degrees Fahrenheit, and, in general, the cooler end of the range is ideal. Sleeping in a cooler room generally helps you fall asleep faster, promotes faster metabolism, and helps regulate hormone systems – especially significant for women at or reaching menopause. Cooling Mattresses || If your mattress is contributing to your overheating tendencies, consider switching to a mattress with cooling technology. The latest models, through a special combination of breathable, ventilating materials, can help you sleep up to eight degrees cooler than a regular mattress. In essence, these cooling mattresses help regulate your body temperature throughout the night, so you don't wake up hot halfway through your sleep cycle. Sleep Accessories || In addition to your mattress, other factors affect your sleep temperature and overall sleep quality, starting with your pillow. Going beyond firm or plush, you may want to consider a cooling pillow that's cool to the touch and retains less heat than a regular pillow. You may also want to try other temperature-regulating accessories, such as pillow protectors that control moisture while you sleep. You should also wear 100% natural fibers like cotton for sleeping, since synthetics and blends are less breathable and can overheat the body.
