Water treatments for headaches use a combination of heat and cold to draw blood away from the affected area. Try soaking your feet and ankles in a hot foot bath while applying an ice pack or a cold cloth to the forehead and temples, says Tori Hudson, N.D., a naturopathic physician and professor at the National College of Naturopathic Medicine in Portland, Oregon. When you use an ice pack, many experts suggest wrapping it in a plastic bag and placing it over a towel on the skin. Also, they advise limiting your cold treatment to 20 minutes, since prolonged exposure could damage the skin. This treatment is very effective for tension and sinus headaches and can be used as needed, says Dr. Hudson.
