There is currently no way to prevent hot flashes. Nor is there a method available that will predict when hot flashes will begin or how long they might last. Women can often reduce the frequency or severity of hot flashes by following these general guidelines:

• Exercise regularly. Try to get at least 30 minutes of exercise on most days of the week. In addition to helping maintain a healthy body weight, exercise can also reduce stress, which may cause hot flashes.
  
  
• Maintain a healthy weight. Women should maintain a weight deemed healthy by their physician. Several studies have suggested that a high body mass index may increase a woman’s severity and/or frequency of hot flashes, according to the American College of Obstetricians and Gynecologists (ACOG).
  
  
• Quit smoking. According to the ACOG, women who smoke have more severe and more frequent hot flashes compared to those who never smoked or who were former smokers. Additionally, the more a woman smokes, the greater the reported risk of having hot flashes.
  
  
• Eat a healthy diet. Women should eat plenty of whole-grain products, vegetables, fruits and soy products. Some health experts believe that increasing the number or amount of legumes consumed in the diet can help reduce hot flashes. Common foods that contain soy are tofu, tempeh, miso, soy milk, whole soybeans, texturized vegetable protein and soy powder. Certain products, such as chocolate or caffeinated beverages, may increase hot flashes in some women.
  
  
• Drink in moderation. Women should not have more than one alcoholic drink per day. Wine and other liquor has been known to increase hot flashes in women.
  
  
• Maintain a cool environment (drop thermostat and/or use a fan).
  
  
• Dress appropriately. Women who experience hot flashes may find relief by dressing in layers and wearing natural fabrics, such as cotton or silk that can “breathe” instead of polyester. Since chills may follow hot flashes, it is convenient to have clothing that can be easily added and removed.
  
  
• Practice relaxation techniques. Some women find that yoga, acupuncture and biofeedback help with hot flashes.

Hot flashes may also be reduced by avoiding spicy foods and foods or beverages containing caffeine. Good health and sound lifestyle choices can reduce the likelihood of symptoms. However most women will experience at least some ill effects associated with menopause.
