DEAR DOCTOR K: What can I do to relieve uncomfortable hot flashes?
DEAR READER: Yesterday I discussed new research showing that menopausal hot flashes can last for much longer than the "several years" the textbooks say they are supposed to last. We are beginning to understand why women in menopause (and sometimes for years after) get hot flashes. There is a center in the brain that is constantly measuring the inner temperature of our bodies. For example, body temperature rises on a hot day, or when we exercise. When the brain center thinks the body needs to cool off, it causes little blood vessels near the skin to open wide.
