Not all women who go through menopause have hot flashes. It's not clear why only some women get hot flashes. The following factors increase your risk:

  • Smoking. Women who smoke are more likely to get hot flashes.
  • Obesity. A high body mass index (BMI) is associated with a higher frequency of hot flashes.
  • Physical inactivity. If you don't exercise, you may be more likely to have hot flashes during menopause.
  • Ethnicity. More African-American women report menopausal hot flashes than do women of European descent. Hot flashes are less common in women of Japanese and Chinese descent than in white European women.
