Electromagnetic therapy is harmless and effective, and it consists of passing controlled energy waves through the body to help correct the body’s balance. This alternative treatment can be used to successfully treat a variety of ailments, including depression, arthritis and migraines. But if you’re new to this type of treatment, what can you expect? The treatment is administered by magnets, and these are in contact with your skin, often the same areas that acupuncture targets. The magnet might be in a bracelet, in a band aid or even inside a special mattress pad. As to how long it takes to take effect, it depends on the condition or ailment being targeted; much of the time results aren’t immediate. Although this type of treatment is safe for most people, you shouldn’t undergo the therapy if you are pregnant or use a pacemaker.
