What is the average body temperature while sleeping

Your body has an internal thermostat and it aims to maintain your temperature as close to your goal as possible. Each day, your body has plans to adjust your temperature to follow your circadian rhythm by warming you up to start the day and cooling you down for sleep. Yet diet, exercise, hormones, and many other things affect your temperature. As a result, your body is constantly making adjustments to keep it all balanced:. Generally, this means your body temperature is at its lowest a few hours before you wake and its highest an hour or two before bed.

Anything outside of that range indicates that something is challenging your body and preventing it from adjusting. At the surface of your skin, where heat from your blood and cold from the environment are more intermingled, the range is typically much larger. Your skin temperature and core temperature can even change in opposite directions throughout the day. For example, if your core temperature is too high, your body tries to cool itself by pushing blood to the skin so it can shed that excess heat.

But in the case of fever, or after ovulation, both will rise similarly. During the day, your temperature varies as you move, eat, drink, socialize, and change your environment.
