Heating pads can help relieve menstrual cramps by increasing blood flow to the affected area, relaxing muscles, and reducing pain and discomfort. The heat from the pad can also help to soothe and comfort the area, which can help to alleviate pain and reduce the intensity of cramps. Additionally, heat therapy may stimulate the release of endorphins, which are natural painkillers that can help to further reduce discomfort. Overall, heat therapy can be an effective and non-invasive way to help manage menstrual cramps and provide relief from menstrual-related pain.
