Magnets can promote blood circulation, reduce blood viscosity and improve sleep. It can be seen that magnets are good for the human body and have no harm.
But if you want magnets to help treat diseases in the body, then this is uncertain. At present, there are many advertisements and news praising the efficacy of magnets. It can be said responsibly that magnets can only play an auxiliary role and can never cure any diseases. Please don't be fooled.
As mentioned above, if you buy a bra with a magnet, you don't expect to have the effect of breast augmentation, but it can reduce and prevent breast diseases.
