What Are Night Sweats?

Night sweats, medically termed "sleep hyperhidrosis," are episodes of nocturnal sweating, which can range from mild to severe.

Common symptoms of night sweats include:

  • Sudden and intense feelings of heat
  • Sweating
  • Irregular heartbeat

  • Insomnia

Women who are suffering from night sweats during menopause may experience both mild and severe episodes, which range in intensity and frequency during the night.

Who Is Affected by Night Sweats?

Many women in their 40s and 50s experience night sweats; however, they can also occur while a woman is still menstruating. The majority of women tend to develop symptoms 2 - 10 years before menopause during a stage known as perimenopause.

Research shows that not all women are affected by night sweats in the same way, and other factors, such as age and race, can influence how likely a woman is to develop night sweats during the menopausal or perimenopausal transition.

Night sweats are often experienced most intensely during perimenopause, the stage prior to menopause. After that, hormone levels even out, and night sweats tend to subside. However, approximately 10% of women continue to experience night sweats during postmenopause.

When Should I See a Doctor?

Although night sweats are a common and normal symptom of menopause or perimenopause, a woman with questions or concerns should talk to her doctor. Though relatively rare, there are more serious causes of night sweats that happen during this time. Some serious symptoms that may warrant a trip to the doctor include:

  • Problems with breathing during sleep
  • Infection or fever
  • Chronic fatigue
  • Persistent coughing
  • Drastic weight loss
