How long can graphene belt be used for lumbar treatment every day?
Graphene is a kind of conductor material, which has very good electrical conductivity and thermal conductivity, and the electric energy conversion rate can reach 99%. Therefore, using graphene as a conductor material can give full play to the far infrared effect. Achieve the effect of eliminating dampness and dispelling cold. It is advisable to use it for 45 to 60 minutes every day, but you must stick to it. To be effective.
