Use a Heat Patch
Placing a heated patch or wrap on your abdomen helps relax the muscles of your uterus [1]. These muscles are responsible for the cramps. Heated pads also help increase blood circulation in the abdomen, and as a result, reduce pain.
Research shows that heating pads are more effective than acetaminophen (Tylenol) [2] in reducing period cramps. You can purchase abdominal heat patches at any drugstore close to you. They are easy to use. All you have to do is peel and stick them on your abdomen. Electric heating pads and hot water bottles are not as effective and comfortable as patches, but they are good choices especially if you don’t have to move around a lot.
