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.

Night sweats can produce a host of symptoms. While every woman experiences night sweats differently, the following are the most common symptoms of night sweats.

Common Symptoms of Night Sweats

  • Heart palpitations and rapid heartbeat
  • Nausea

  • Flushing

Q: What Causes Night Sweats?

The short answer: Fluctuating hormone levels in the body.

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. This can provoke the hypothalamus - the part of the brain that regulates body temperature - to perceive that the body is "too hot." In response, it launches a series of the physiological reactions to down, such as sweating and flushing.

Additionally, some medical conditions can cause night sweats. A woman who experiences night sweats accompanied by other unexplained symptoms may wish to speak with her doctor.
