Question: What Causes Hot Flashes? What Happens to My Body During a Hot Flash?
Answer: The exact cause of hot flashes is unknown -- they might be caused by decreased estrogen or even a change in another hormone. During a hot flash, the part of your brain that controls body temperature is affected. You might feel a sudden wave of heat move from your chest to your head during a hot flash, your face may turn red, and sweating may occur. Certain things sometimes trigger the onset of hot flashes including:

  • Hot weather
  • Hot or spicy foods
  • Alcohol
  • Caffeine

Avoiding things that trigger your hot flashes can significantly lower the intensity of your hot flashes, as well as the number of hot flashes you experience during menopause and perimenopause.
