Q: What Are Night Sweats?

Medically termed "sleep hyperhidrosis," night sweats are similar to hot flashes, but are chiefly characterized by excessive or abnormal sweating during sleep. The hormonal imbalance that occurs during menopause triggers increased heart rate, blood flow, and perspiration.

In addition to these effects, night sweats can also negatively affect sleep patterns, causing fatigue and irritability in a woman's daily life. Please read on to learn more about the specific symptoms of night sweats.

Q: What Causes Night Sweats?

Did You Know?

In women with high levels of anxiety, night sweats are five times more likely to occur.

The longer answer: During the menopause transition, the body decreases estrogen production.
