About Night Sweats

While night sweats, the nocturnal cousin of hot flashes, can be uncomfortable and disruptive, they don't usually signal a more serious underlying condition. In fact, night sweats are one of the most common companions of menopause, which typically begins in a woman's late 40s to early 50s. Scientific studies suggest that as many as 75% of menopausal women experience night sweats.

Definition of 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 hot flashes, which can affect menopausal women during the waking hours.
Both symptoms have the same basic underlying physiological cause: hormonal imbalance. Menopause-related night sweats and hot flashes usually follow a pattern consistent to the particular woman whether multiple times a night or just once a week.
Oftentimes, night sweats are so intense that they interrupt a woman's sleep, even if they don't wake her up. These sleep disruptions can affect a woman's daily life and increase the likelihood of irritability and increased stress. |

Most women begin to develop symptoms three to ten years before actual menopause, a span of time called perimenopause.

Research shows that not all women are affected the same. Age, race, and other factors can influence how likely a woman is to develop night sweats during menopause.

Race

Studies have found that the prevalence of night sweats varies by racial group. One large study found the 3 in 4 white women experience night flashes.
