Q: What are Night Sweats?
Medically termed "sleep hyperhidrosis," night sweats are the nocturnal version of hot flashes. They are chiefly characterized by excessive or abnormal sweating during sleep. The hormonal imbalance that occurs during menopause provokes the heart to race, the body to heat up, and perspiration to flow.
In addition to these effects, night sweats also have the secondary consequences of interrupting sleep and affecting women's waking life. Please read on to learn more about the specific symptoms of night sweats.
Q: What are the common 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

• Sudden and intense feelings of heat
• Sweating (mild to profuse)
• Heart palpitations and rapid heart beat
• Nausea
• Headaches
• Flushing
• Chills
• Damp to soaking clothes and bedding
• Frequent interruptions of sleep
• Loss of sleep or insomnia |
Q: What causes night sweats?
The short answer: Fluctuating levels of hormones in the body.
The longer answer: During the time of menopause, the body begins to produce less estrogen. 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 cascade of the physiological reactions that menopausal women experience as hot flashes or night sweats. |
In women with high levels of anxiety, night sweats are five times more likely. |
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.
Q: When can women expect to start having night sweats?
Many women in their 40s and 50s develop night sweats, which often begin before the actual cessation of a woman's menstrual cycle. One study found that approximately 19% of women aged 40 to 55 who still had regular periods experienced night sweats. Most women begin to develop symptoms three to ten years before actual menopause, a span of time called perimenopause.
Q: How long will night sweats continue?
Night sweats are often at their most intense during perimenopause. After this, a woman´s body adapts to its new hormone levels and night sweats tend to subside. However, approximately 10% of women continue to experience night sweats after menopause.
Luckily, women can take several measures to reduce the frequency and duration of night sweats. Keep reading to find out how to avoid night sweats and what treatment options are available.
