“We found that night sweats are associated with a state of arousal, and some of the things that cause people to have night sweats include [antidepressants] or blood pressure medications, alcohol, or eating too close to bed,” says Mold. ” Tell. Each may interfere with the body’s natural metabolic or temperature control mechanisms, thereby disrupting or reducing sleep, their research suggests.

Intense exercise too close to bed can “throw off” the body’s thermoregulatory processes, says Michael Grandner, MD, professor and director of the Sleep and Health Research Program at the University of Arizona School of Medicine. He explained that a person’s body temperature naturally drops before sleep, which promotes sleep. Eating or exercising too close to bed can speed up your metabolism, which increases heat production and hinders the body’s natural cooling.
But what about those sudden heat waves on those nights when you just can’t sleep? It can be caused by everything from an overactive brain to your favorite bedding or clothing. “Night sweats are often caused by pajamas, mattresses, and sheets that don’t breathe well,” says Grandner.
Grandner explains that your body’s built-in sleep clock lowers your core temperature an hour or two before bedtime, and once you fall asleep, it will continue to drop slowly until it reaches . Doesn’t reach low point around 3am. Anything that disrupts normal temperature development can disturb your sleep. If you’re nice and cool when you go to bed, wearing thick pajamas or an extra-warm blanket can trap heat, disrupting your body’s natural drop in temperature and keeping you awake.
There is also some evidence linking insomnia to higher levels of stimulation of the autonomic nervous system, including faster heart rate, higher metabolism and increased body temperature. While the research is a bit grainy, it suggests that an overactive and agitated mind — associated with worries or thoughts about the day ahead — can lead to the release of the stress hormone cortisol, which is responsible for some of the heat-producing substances. Can increase internal functions.

This may explain why, on sleepless nights, you throw back the covers and move the pillows in search of quiet rest.
To prevent sweating, replace your existing bedding with blankets and sheets that breathe well and keep cool. Untreated cotton is always a good, affordable option. Grandner also says that many foam mattresses trap heat; Be sure to choose a mattress (and a mattress pad or base) that will help promote cool sleep.
Sleeping with one leg outside the covers can also help. “The bottom of the foot has an important temperature-sensing function and can help the body retain coolness even under warm blankets,” says Grandner. The same happens with your neck, so try to keep your neck and head away from the blanket. (Several studies show that cooling your head at night, either with a cooling cap or by turning down the thermostat, can combat insomnia.)
If you think your night sweats are due to medications or menopause, tell your doctor. He may be able to change your medicine to prevent your symptoms. For hot flashes related to menopause, says Joffe, there are drug treatments—both hormonal and not—that can help.
