Menstrual cramps, or period pain, are normal. While some menstruating women experience no symptoms at all, there are those who have mild to severe pain. According to StatPearls Publishing, one out of ten women experience pain that is so bad that they are unable to carry out their daily activities on one to three days every month.
During such intense times, home remedies and pain medications (prescribed by doctors) may help. A heating pad, or hot water bag, is one of the most common remedies to relieve period pain. It is what women apply to relieve pain in different parts of the body during menstruation. We asked an expert how safe it is to use and safety measures to follow while using it.

Does Heating Pad Help Relieve Period Pain?
Studies suggest that heating pads, patches, or belts can relieve period pain. According to research published in UpToDate, applying heat to the lower abdomen with a heating pad, hot water bottle, or self-heating patch can significantly reduce pain, often as well as treatment with a Nonsteroidal Anti-Inflammatory Drug (NSAID).
However, it is important to avoid burning the skin with such devices, as they can be very hot. The research article recommends a temperature of approximately 104°F (40°C).
Talking about the benefits of using heat therapy, Dr Danny Laliwala, Consultant—Obstetrics and Gynaecology, Jaslok Hospital & Research Centre, Mumbai, shares, "Heat therapy increases blood flow to the area, relaxes the uterine muscles, and reduces prostaglandins, which cause cramps, which helps relieve the pain temporarily."
She told the OnlyMyHealth team that this action is enhanced along with a painkiller like an NSAID or a smooth muscle relaxant. "It is better to consult your gynaecologist along with an ultrasound of the pelvis before undergoing any such therapy. It is advisable to rule out certain conditions like fibroids, polyps, and adenomyosis," she added.
How Long Should You Use Heating Pads For Menstrual Cramps?
It's recommended to use a heating pad for 15-20 minutes at a time, with a 30-minute break in between, says Dr Laliwala, adding that following this time period helps prevent burns and skin irritation.
