Some women even develop insomnia. Others have experienced that caffeine, alcohol, hot drinks, spicy foods, and stressful or frightening events can sometimes trigger a hot flash. However, avoiding these triggers will not necessarily prevent all episodes. Hot flashes appear to be a direct result of decreasing estrogen levels. In response to falling estrogen levels, your glands release higher amounts of other hormones that affect the brain's thermostat, causing body temperatures to fluctuate.
Hormone therapy relieves the discomfort of hot flashes in most cases.
Some women claim that vitamin E offers minor relief, although there has never been a study to confirm it. Dress in layers so you can remove them at the first sign of a flash. Drink a glass of cold water or juice at the onset of a flash. At night keep a thermos of ice water or an ice pack by your bed. These changes can make sexual intercourse uncomfortable or painful.
