Why Do I Get So Hot When I Sleep? Even in the middle of winter, you may wake up covered in sweat, with your blanket or comforter hanging off the bed. If you’ve been wondering why this occurs, you’re not alone. Interestingly, your body has a unique set of systems that help it regulate throughout the day and while you sleep. Thermoregulation, the process of keeping the body at optimum temperature, is one reason why you may wake up feeling overheated or sweaty. Brain temperature rises during REM sleep, which can affect the temperature of the body and its surroundings.
Other Factors that Cause Hotness During Sleep In addition to the natural body functions that cause a boost in sleeping temperature, there are a variety of other factors that may cause you to feel hot at night. Night sweats and hot flashes are common symptoms among women with menopause, and can occur in men when testosterone levels drop. Additionally, conditions such as fevers can cause you to feel overheated during sleep. Those who engage in rigorous exercise before bed may also experience a significant increase in sleep temperature. If you’re not of menopausal age or have other reasons — i.e. medications that case night sweats — to believe that your sleeping temperature is too high, consider consulting your doctor.
Staying Cool During Sleep The National Sleep Foundation suggests that wearing cooling pajamas that lower your body temperature by just a single degree can help you get a better night’s rest. In the same vein, you can invest in temperature-regulating bedding to help keep your environment cool and to deter symptoms associated with night sweats, hot flashes and overheating during sleep. Cool-jams makes cooling bedding and temperature regulating pajamas for men and women that will help you cool down your sleep space.
