What it is
As estrogen falls, the brain's thermostat becomes oversensitive. Tiny rises in body temperature that you never used to notice now trip a full cooling response: flushed skin, sweat, a pounding heart. That is a hot flash.
A night sweat is the same event while you sleep. It can wake you soaked, and the broken sleep often costs more than the flash itself.
About three in four women get them. They usually start in perimenopause, peak around the final period, and last about seven years on average. Treatment can help at any point.

Follow-up
A visit at 8 to 12 weeks checks whether the dose is right.
Questions people ask
- How long do hot flashes last?
- About seven years on average, and for some women more than a decade. Treatment can help at any point.
- What is the most effective treatment for hot flashes?
- Estrogen. It is the most effective treatment for hot flashes and night sweats. Dr. Mueller goes through your history first: breast cancer, blood clots or stroke change the plan.
- Can I treat hot flashes without hormones?
- Yes. Fezolinetant is an FDA-approved non-hormonal pill made for hot flashes. Some low-dose antidepressants also reduce them.
- Do hot flashes mean menopause has started?
- Not by themselves. They usually begin in perimenopause, while periods still come. Menopause means 12 months without a period.
- Are hot flashes dangerous?
- A flash itself is not harmful. But frequent flashes break up sleep and drag down mood, and that is worth treating.
