Hot flashes are common during menopause, as well as in perimenopause, which is the stage before menstruation stops.
A 2015 study found that
Neither hot flashes nor menopause is dangerous or a symptom of an illness. The sudden rush of heat during a hot flash can be unpleasant, though.
In this article, learn more about how a hot flash feels and what to expect.
Hot flashes cause a sudden sensation of heat in the upper body. A person might experience symptoms in the chest, arms, neck, or face.
The heart rate also tends to increase during a hot flash, intensifying the sensation of heat. Most hot flashes last between
The frequency of hot flashes varies significantly among individuals. For instance, they can happen many times an hour, a few times a day, or less than once a week. Some people find that their hot flashes follow a predictable pattern.
During a hot flash, blood vessels in the upper body expand, allowing more blood flow to the area. This increased blood flow can cause blotchy patches on the skin, or flushing.
After a hot flash, as the body attempts to cool itself, a person may experience sweating that causes them to feel cold or shiver.
However, some people experience early menopause in their 30s. Others may continue menstruating into their late 50s or even early 60s.
Age is generally a good predictor of menopause, though, and it can help with determining whether a sudden feeling of heat is a hot flash or something else.
Even when menopause is the culprit, it is important to see a doctor when symptoms appear very early.
Some other symptoms of menopause include:
- Period changes: Menopause is when a person goes
12 monthswithout a period. During perimenopause, it is common to experience changes in periods. Periods may get lighter, irregular, closer together, or less frequent.
- Physical changes: Many people notice that their weight distribution changes during perimenopause and when they stop menstruating. Their waist might expand, and they may have more difficulty maintaining muscle mass.
- Aches and pains: Some people report headaches, muscle pains, or muscle spasms.
- Mood changes: Fluctuating hormone levels can affect a person’s mental health and mood. Some people also feel emotional about the transition to menopause. People might feel excited to begin a new chapter or sad to reach this natural transition — or both at the same time. Additional stresses, such as aging parents, a history of depression, or fatigue from sleep loss, can also contribute to mood changes.
- Sex life changes: Vaginal dryness is common during menopause. Some people report that sex becomes more uncomfortable, which may be due to dryness and thinning skin. A person’s attitudes about sex might also change.
- Heart health and vascular changes: Blood pressure may go up during menopause. Some people also report having a racing heart.
- Bladder issues: Some women experience an increase in bladder infections or pain. Others may have to manage incontinence or leaks.
- Sleep problems: Hot flashes can make sleep difficult, causing night sweats and other symptoms. Even without hot flashes, many people experience changes in sleep leading up to menopause. Some have insomnia, nightmares, or other sleep disturbances.
Certain lifestyle changes can ease hot flashes and some other menopause symptoms. A person can try:
- limiting alcohol, spicy food, and caffeine if these make symptoms worse
- using a portable fan or water mister when hot flash symptoms appear
- dressing in layers so that it is easier to remove clothing and cool off
- quitting smoking, if applicable
- practicing meditation, mindfulness, and other mind-body interventions, which can ease stress and may help with hot flashes
- breathing slowly and deeply during a hot flash
Paroxetine (Paxil), a type of antidepressant, may help relieve hot flashes in cases where lifestyle changes are ineffective, or a person wants to avoid taking hormonal medications.
Most people take the drug at lower dosages than they would for depression. However, when someone experiences depression along with menopause, a doctor may recommend a higher dosage.
The safest strategy is to take hormones at the lowest effective dosage and for the shortest possible time.
Hot flashes are a sudden feeling of heat in the upper body, including the chest, arms, neck, and face. They may occur with an increased heart rate and flushing.
Hot flashes can be annoying, stressful, and uncomfortable. However, this common symptom usually fades as a person’s periods disappear, and they enter menopause.
Many home remedies and lifestyle changes can make hot flashes easier to manage. People can also ask a doctor about medications to relieve symptoms.
