About Night Sweats

Night sweats, medically termed "sleep hyperhidrosis", are episodes of nighttime sweating, which can range from mild to profuse. Night sweats are similar to the hot flashes that can affect menopausal women during the waking hours.

Oftentimes, night sweats can be so intense that they interrupt a woman's sleep, which can affect many aspects of her daily life. Common symptoms of night sweats include: sudden and intense heat, irregular heartbeat, nausea, flushing, chills, and headaches.

Women with menopause-related night sweats may experience anywhere from mild to severe symptoms of these night sweats, varying in duration, during their usual sleeping hours.

Night sweats are a common complaint of menopausal women, but the cause is not always hormonal. Alcohol consumption not only triggers and aggravates night sweats; it makes the sweat produced more likely to be odorous, too. Cutting back on alcohol in the evening will enable deeper, more restful, sweat-free sleep.


There is a variety of symptoms associated with menopausal night sweats, including excess perspiration, nausea, and irregular heartbeat. The cause of night sweats is thought to be linked with decreased hormone levels. Maintaining a healthy lifestyle is an important first step in managing night sweats. This includes elements such as a balanced diet and exercise.


Causes of Night Sweats

Many women who experience night sweats want to know the reason behind this symptom of menopause. While the exact cause of night sweats is unknown, most experts point to hormonal imbalance as the primary culprit.

Hormonal causes

Graph: Estrogen levels during menopauseDuring menopause, levels of the hormone estrogen become erratic and eventually begin a steady and permanent decline. This change in estrogen levels affects the hypothalamus in the brain, which is responsible for the regulation of body temperature. As a result, the hypothalamus often prompts a series of physiological reactions, which women experience as hot flashes or night sweats.

Other causes

While hormonal imbalance is by far the most common cause of night sweats in menopause, there are also rare medical causes, such as diabetes, anxiety, neurological conditions, sleep apnea, cancer, and thyroid disorder.

Night sweat triggers

Certain factors can intensify night sweats or make them more frequent. Avoiding these triggers can help to alleviate both hot flashes and night sweats.

Environmental Triggers

• Excess bedding

• Close proximity to bed partner
