Things you may want to try at home include:

• Exercise. Studies have found that physical activity may ease the pain of menstrual cramps.
• Heat. Soaking in a hot bath or using a heating pad, hot water bottle or heat patch on your lower abdomen may ease menstrual cramps. Applying heat may be just as effective as over-the-counter pain medication for relieving menstrual cramps.
• Dietary supplements. A number of studies have indicated that vitamin E, omega-3 fatty acids, vitamin B-1 (thiamine), vitamin B-6 and magnesium supplements may effectively reduce menstrual cramps.
• Avoiding alcohol and tobacco. These substances can make menstrual cramps worse.
• Reducing stress. Psychological stress may increase your risk of menstrual cramps and their severity.
