I have been observing for quite sometimes now since I started many months ago. Basically, the only reason that is helping the pain most people are suffering is the Anions (negative ions), which helps our cells regeneration rather than degeneration due to old age and wear & tear of our body joints and parts.
However, there is no specify time and what and how it will affect each and everyone of us, as all of us our body constitutions are different. In general, the more you wear, the faster and effective it has on our body. And also not forgetting the methods of wearing, washing the clothing.
There are some effects take months to improve, some take only 1 night to have improvement. It really depends, but I also don't think the seriousness of the illness will affect the improvement. It is just how determine you are to improve your own conditions and how have you use them enough to make your blood flow smoothly throughout your whole body.
Another plus point, there is no risk. It is not consumable thus nothing goes into the body.
