Summer is starting to wind down and the nights are getting cooler making for less sweaty, uncomfortable sleeping conditions. However, for many people, the sweltering temperatures have nothing to do with whether or not they wake up drenched in sweat.

According to Bustle, 3% of people suffer from night sweats. It is when a person sweats excessively while sleeping regardless of the room temperature. There are several different causes for the condition.

Director of the Sleep & Health Research Program at the University of Arizona College of Medicine, Michael Grandner revealed in an interview with Time magazine that a person's core body temperature drops a couple of hours before bedtime. He explained every person has what is referred to as a "built-in sleep clock", which continues to fall until it is at its lowest point in the middle of the night.

Although the entire process of one's body temperature dropping is entirely normal, night sweats occur when certain factors cause the body’s temperature to rise instead of cooling down. If a person is still drenching their sheets with sweat at night, but the room temperature is cold, they are wearing regular pajamas and are not using blankets; there can be cause for concern.

Medicine is a significant contributor to night sweats. Everything from aspirin to anti-depressants can cause a side effect of sweating too much at night. The reason again is because certain medicines can cause one’s body temperature to increase, which interrupts the cooling process. Hormone imbalance can also cause a person to wake up soaking wet.

Exercising too close to bedtime will leave one's body temperature on the rise at a time it should be cooling down. Anxiety and insomnia will also keep a person's core temp too high, interrupting the process of it lowering at night.

The reason night sweats are concerning is that the body's natural process is interrupted and that means a person is not getting a good night's sleep. When people lack sleep, it affects all aspects of their lives. If you are experiencing night sweats but have taken all sorts of measures to keep cool, you should see a doctor. Too many nights of interrupted sleep are bad for business, so everyone should be wary of how much he or she sweats at night.
