1. Quick warming.

The heat patch provides immediate warmth through internal chemical reactions, such as the reaction between iron powder, activated carbon and other components with oxygen in the air, releasing heat. This heat can offer an instant warm feeling to the body, especially suitable for workers in cold environments, such as sanitation workers and police on duty, as well as people with weaker constitutions, like the elderly, children and pregnant women. In winter, heat patches can effectively alleviate the discomfort caused by cold and prevent the occurrence of diseases like colds.

2. Promote local blood,circulation and relieve pain.

The heat generated by the heat patch can promote local blood circulation, causing the surrounding blood vessels to dilate and the blood flow speed to increase. This effect helps relieve muscle tension and pain caused by cold or fatigue, especially for patients with arthritis, low back pain, and leg pain. The heat patch can play an auxiliary therapeutic role. Applying the heat patch to the painful area, such as the waist or legs, can bring about a significant relief effect.

3. Improve sleep quality.

The warm environment created by the heat patch also helps promote the activity of the parasympathetic nerve, making people feel physically and mentally relaxed, and thereby improving sleep quality. For those who have difficulty falling asleep or wake up easily, applying a heat patch to the soles of the feet or other parts of the body before going to bed can help improve sleep conditions and promote physical and mental health.
