About 90 percent of men and 95 percent of women suffer from headaches each year, according to the National Headache Foundation. "Erratic sleep schedules, skipping meals, stress and overstimulation can be triggers," says Dr. Merle Diamond of the highly rated Diamond Headache Clinic in Chicago. Some simple lifestyle adjustments could help prevent the pain in your cranium.

• Give your mind some time to relax. Maintain a regular sleep schedule by going to bed and waking up at the same time each day.
• Your body produces endorphins when you work up a sweat, so exercise can be a powerful protector, says Dr. Juline Bryson of the highly rated Headache Institute in New York City.
• The effects of stress on your body's health are wide-ranging, and headaches are among them. Reduce stress by improving your time management, relaxing and doing yoga or meditation.
• Avoiding certain foods may decrease your chance of headache. Triggers include aged cheese, nuts, citrus, chocolate, and foods with additives like MSG, nitrates and aspartame.
• It's no surprise alcohol can cause headaches. "Never have more than two drinks per night," says Bryson, who recommends drinking two glasses of water per alcoholic beverage.
