Nua Cramp Comfort Heat Patch 3 is used for providing relief from menstrual cramps. It is a revolutionary self-heating patch designed specifically to help alleviate period pain. This innovative patch is air-activated, meaning it begins to emit soothing heat as soon as it comes into contact with the atmosphere. Each patch is designed to provide effective relief from cramps for up to 8 hours, allowing for a more comfortable and less painful menstrual experience. The key ingredient in the Nua Cramp Comfort Heat Patch is iron powder. When the iron powder oxidises upon exposure to oxygen, it generates heat, delivering gentle warmth directly to the area of discomfort. This is particularly beneficial just before menstruation when uterine muscles tighten to expel the lining, resulting in painful cramps. By applying the heat patch, users can help relax these muscles, promoting the smooth passage of menstrual blood and significantly reducing discomfort. Nua Cramp Comfort Heat Patch is not just about pain relief; it also enhances overall well-being during menstruation, enabling women to go about their daily activities with greater ease and comfort.
