(DO NOT tumble dry) Information about magnetic therapy. Magnetic therapy is based on the theory that magnets near to the skin will help to increase the blood flow to the affected area. An increased blood flow will mean that there are more healing properties going to that area. This can help to keep the area warm and reduce the pain, but also help to heal the injury and help it to recover more efficiently.
