What Causes Night Sweats in Women?

All of the causes listed in a previous section can lead to night sweats in women. The problem usually occurs during times when hormones are changing, such as:

  • menopause, which often causes night sweats and hot flashes
  • pregnancy
  • right after delivery, in which case the doctor may refer to "postpartum night sweats"

What Causes Night Sweats in Men?

The causes are common and can also affect men.

Excessive sweating is a feature of low testosterone or hypogonadism. About 39% of men 45 years and older can experience this drop in testosterone. They might also experience night time sweats as a result. However, there seems to be little evidence to support this idea.

A doctor may suggest hormonal treatment or perform tests to identify the cause of the sweating.


Night sweats are a symptom, not a clinical condition. By taking a complete medical history, your healthcare professional will usually be able to determine if you have night sweats. The patient will be asked to describe the situation, including how often and when they occur, and if there are other associated symptoms. A physical exam along with the medical history can help determine the cause of the night sweats and direct further tests.

Blood tests may be done if the diagnosis is unclear, either to measure hormone levels or to look for signs of other conditions (such as an infection) that could be responsible for night sweats.


To treat night sweats, your doctor will take steps to address its underlying cause. The treatment will depend on your specific diagnosis.

  • If you experience night sweats because of menopause, your doctor may recommend hormone therapy. This treatment can help reduce the number of hot flashes you experience and relieve other signs, and may also prescribe other medications, such as gabapentin, clonidine, or venlafaxine, which are used off-label for night sweats.
  • If an underlying infection is the cause of your night sweats, your doctor may prescribe antibiotics, antiviral medications, or other medications to help treat it.
  • If your night sweats are caused by cancer, your doctor may recommend a combination of chemotherapy drugs, surgery, or other treatments.
  • If your night sweats are related to the medications you are taking, your doctor may adjust your dose or recommend an alternative medication.
  • If alcohol consumption, caffeine consumption, or drug use are the cause of your night sweats, your doctor may recommend that you limit or avoid these substances. In some cases, they may prescribe medication or recommend therapy to help you quit smoking.
  • Your doctor may also recommend that you change your sleeping habits. Removing blankets from your bed, wearing lighter pajamas, or opening a window in your bedroom can help prevent and relieve night sweats. It can also help to use air conditioning or a fan, or find a cooler place to sleep.
