Vests made of graphene heating materials will not only emit heat to make your body feel warm after being electrified, but the core of graphene heating materials is to emit heat through far infrared rays, so if worn on the body, the far infrared rays generated by graphene heating materials can also promote the blood circulation and metabolism of the body.
Simply put, sitting in the office for a long time will lead to poor blood circulation, which will lead to blood vessel blockage, backache and so on. Therefore, the physical therapy function of the fever vest can just eliminate these symptoms of the body.
This is some explanation according to the product characteristics, I hope it will help you!
