My family had a birthday party for my mother recently. Even though it's downright chilly here, my oldest sister was wearing a short-sleeved shirt and kept fanning herself. Since I'm 15 years younger than she is, I got a little laugh out of her hot flashes. But it's only a matter of years before my time comes.

While the cause of hot flashes during perimenopause and menopause aren't fully understood, there are several health-related possibilities. Women who smoke are more likely to have hot flashes -- one more reason to quit -- and women who are overweight or obese are also more likely to have hot flashes. In addition, blood glucose levels may play a role in hot flashes.

If you're currently experiencing hot flashes, talk to your doctor. He/she may have nutrition or fitness suggestions that will help, and there are several medications that can help as well. If, like me, hot flashes are only a future possibility -- take action now. Make sure you maintain an appropriate weight and eat healthfully.
