Why Body Temperature Changes While You Sleep

Why I get too hot while sleeping

Do you tend to get too hot while you sleep? The bad news is that it’s just a part of your body’s physical chemistry, so there’s nothing much you can do to change that. But the good news is that there are plenty of ways to alleviate that extra heat you accumulate at night. Find out why your temperature rises at night and how you can deal with it for a better night’s sleep.

Natural Temperature Regulation at Night:  Everyone’s body follows a 24-hour cycle that’s linked to when you wake up and when you go to sleep. Your core temperature actually decreases when you’re in deep sleep, but as your body transitions to the wake phase, your core temp starts to heat up. As you probably know, you sleep well during those deep sleep phases when your body temperature goes down. But as you warm back up, you start to feel more alert and awake. This is the body’s natural way of waking you but, as you’ll see in the next section, it can also cause sleep disturbances.

Getting Too Hot at Night: It’s not only the body temperature warming back up that causes people to get too hot at night, it can also be due to the fact that people want more blankets on when that core temperature is dropping. As a result, they end up feeling too warm when the body is ready to get back to its normal temperature and the excess heat wakes them up.

Combating Excessive Heat at Night: If you feel yourself being woken up by being too hot at night, you may need to create an environment that’s more conducive to sound sleep. Set your thermostat to be warm enough to fall asleep comfortably, but to cool down over the course of the night. Choose breathable pajamas and temperature regulating bedding fabrics from Cool-jams™ to make sure you don’t get overheated. You can also avoid strenuous activity before bed that will make you too hot to fall asleep. With the information and tips listed here, it’s possible to get a better night’s rest that doesn’t include waking up from being too hot or sweaty at night.
