Believe it or not, there is an ideal temperature for sleeping at night — here, the experts weigh in. Sleeping in a cool, dark space helps support natural sleep cycles. If you find yourself tossing and turning at night more than usual, your room temperature may be to blame. As it happens, the mechanisms in our bodies that regulate sleep are widely affected by temperature, so any fluctuations — hot or cold — can make sleep more challenging. That said, experts agree that sleeping in a dark, cool environment lends itself to high-quality sleep. If your environment is too warm or too cold, it can disrupt this process, causing you to wake up or shift into lighter sleep stages. While we can’t control internal mechanisms that affect our body temperature, like the circadian rhythm, we can adjust external factors such as room temperature, bedding and fabric types to improve our sleep quality. sleep and body temperature are intricately linked and impact each other. All humans operate on a 24-hour circadian cycle that affects everything in our body, from digestion to metabolism to sleeping. Skin temperature rises a bit, pulling blood from your core and then cooling it to promote deeper, more restful sleep A room that’s too hot can make it difficult for your body to reach the ideal cool-temperature stage to fall asleep and can also jolt the body out of deep sleep stages. Older adults and young infants may be especially affected because they have more trouble regulating their internal body temperatures. Additionally, anyone going through hormonal changes, such as with perimenopause and menopause, may also have trouble staying cool, so a room that’s too hot can further impact sleep. lightly colder temperatures are necessary for the body to sleep, a room that is too cold can also interrupt sleep. Specifically, a too-cold environment can make it difficult to get comfortable, fall asleep and stay asleep.
