About three in four women struggle with menopause-related hot flashes.

What is a hot flash?

  • Because your ovaries produce less estrogen, the cells in your hypothalamus, the part of your brain that controls temperature, become imbalanced.
  • These cells send a false signal to your body that it is too hot.
  • When your body tries to lower its temperature, the blood vessels near your skin dilate and try to cool you down.
  • This leads to hot flashes and sweats, also known as hot flashes.

If hot flashes occur while you sleep, they are referred to as night sweats.
