Hot flashes are a common symptom of menopause, affecting more than 75% of women. They are characterised by a sudden feeling of intense heat in the upper body, particularly the face, neck and chest, and can be accompanied by sweating, flushing, and an increased heart rate. While hot flashes themselves are not dangerous, they can be a sign of low estrogen levels, which is associated with negative health impacts such as lower bone density and increased risk of cardiovascular events. There is some evidence to suggest that hot flashes may be linked to a reduced blood flow to the brain, but the exact mechanisms are not yet fully understood.

What You'll Learn
Hot flashes are a common symptom of menopause
Hot flashes are caused by changing hormone levels, specifically the decrease in estrogen levels, which causes the body's thermostat (hypothalamus) to become more sensitive to slight changes in body temperature. This triggers a chain of events to cool the body down. Hot flashes are more common in people assigned female at birth (AFAB) who are in perimenopause or menopause, affecting more than two-thirds of AFAB individuals in North America. They can also affect those whose ovaries do not release enough estrogen due to chemotherapy or hysterectomy.
The frequency and intensity of hot flashes vary among individuals, and they can last for years, with a median duration of seven years. Some lifestyle changes that may help manage hot flashes include avoiding triggers such as hot weather and heated rooms, dressing in layers, staying in cool environments, and practising mind-body therapies such as mindfulness meditation.

Hot flashes are caused by a drop in estrogen
Hot flashes are the most common symptom of the menopausal transition and postmenopausal period. They are caused by a drop in estrogen secretion as women go through menopause. Estrogen is produced by the ovarian follicles, and these structures also contain immature eggs. Women are born with a limited number of follicles, which decline over a woman's life.
During a hot flash, there is a sudden feeling of warmth in the upper body, usually most intense over the face, neck, and chest. The skin might redden, and a hot flash can also cause sweating. If you lose too much body heat, you might feel chilled afterward. Night sweats are hot flashes that happen at night, and they may disrupt sleep.
Hot flashes are caused by the decline in estrogen secretion as women go through menopause. When estrogen levels decrease, the body's thermostat, the hypothalamus, becomes more sensitive to slight changes in body temperature. When the hypothalamus thinks the body is too warm, it starts a chain of events—a hot flash—to cool the body down.
The frequency and intensity of hot flashes vary among women. A single episode may last a minute or two, or as long as five minutes. Hot flashes may be mild or so intense that they disrupt daily activities. They can happen at any time of day or night.
Hot flashes are not just a female experience. Men also experience changes in reproductive function as they age, and a gradual decrease in testosterone can lead to hot flashes. Additionally, men with prostate cancer may experience severe hot flashes as a result of treatments that deplete testosterone production.

Hot flashes can last from 30 seconds to an hour
Hot flashes are the most common symptom of perimenopause and menopause, which is when a person's ovaries stop releasing eggs and their period stops. They can also affect those whose ovaries do not release enough estrogen due to chemotherapy or a hysterectomy.
Hot flashes can last anywhere from 30 seconds to an hour, with an average duration of 1-5 minutes. They can be mild, moderate, or severe, and can occur several times an hour. They can be very uncomfortable and disruptive, causing people to wake up at night and lose sleep. The frequency and intensity of hot flashes vary among individuals, and they can happen at any time of day or night.
During a hot flash, a person experiences a sudden rush of heat in the upper body, including the chest, neck, and face. The heart rate also tends to increase, intensifying the sensation of heat. Blood vessels in the upper body expand, allowing more blood flow to the area, which can cause blotchy patches on the skin, or flushing. After a hot flash, the body may attempt to cool itself by sweating, causing the person to feel cold or shiver.
Hot flashes are caused by fluctuating hormone levels, particularly a drop in estrogen, which changes how the brain perceives temperature. The hypothalamus, or the body's internal thermostat, becomes more sensitive to slight changes in body temperature and triggers a hot flash to cool the body down.
While hot flashes themselves are not dangerous, they can be a sign of low estrogen in the body, which is associated with negative health impacts such as lower bone density and increased risk of cardiovascular events.

Hot flashes can be mitigated with lifestyle changes
Hot flashes are a common symptom of menopause, causing a sudden flare of heat, sweating, and flushed skin. While they are a natural part of aging, they can be disruptive to daily life and cause discomfort.
Additionally, making small changes to your daily routine can help manage hot flashes. Maintaining a healthy body weight, exercising regularly, and practicing mind-body therapies such as mindfulness meditation or cognitive behavioral therapy (CBT) can help reduce the impact of hot flashes. It is also beneficial to keep your environment cool by using fans or air conditioning, drinking cold beverages, and dressing in layers that can be easily removed when a hot flash occurs.
If these lifestyle changes are not sufficient, there are other treatment options available, including prescription medications and hormone replacement therapy (HRT). It is important to consult with a healthcare provider to determine the best course of action for managing hot flashes.

Hot flashes can be treated with hormone replacement therapy
Hot flashes are the most common symptom of perimenopause and menopause, which is when the ovaries stop releasing eggs and periods stop. They can also affect those whose ovaries do not release enough estrogen due to chemotherapy or a hysterectomy.
Hot flashes are a sudden sensation of heat, usually in the face, neck, and chest, and can be accompanied by sweating, anxiety, and nausea. They can last anywhere from 30 seconds to five minutes and can occur several times an hour.
The benefits of HRT include relieving uncomfortable menopause symptoms, improving mood and sleep, reducing the risk of osteoporosis and colon cancer, and lowering the risk of diabetes. However, there are also risks associated with HRT, including an increased risk of uterine cancer (if not taking progestin), heart disease (if started more than 10 years after menopause), blood clots, stroke, gallbladder disease, and breast cancer with long-term use.
It is important to discuss the risks and benefits of HRT with a healthcare provider to determine if it is the right treatment option for you.
