Yes, as far as I know, the hyperthermia of pure graphene far-infrared energy chamber can greatly enhance human immunity. Mr. Kenji Ishihara, a famous doctor of natural medicine in Japan, has written two famous bestsellers: Body temperature determines life and death and illness comes from cold. The book points out that when the body temperature drops by 65438 0℃, the immunity drops by 30%; On the contrary, if the body temperature rises by 65438 0℃, the immunity will be enhanced by 5-6 times. I recommend you to see their graphene energy room.
