Body piercing is probably causing a steep rise in allergies to nickel across the Western world. Nickel is already the most common cause of contact allergy in several European countries. And exposure to the metal can cause lifelong sensitivity. Sensitized individuals find many belt buckles, wristwatches, glasses frames and jewelry impossible to wear.
COMMENT: I would advise the removal of most metal from the body as it tends to interfere with the body’s normal subtle bioelectrical rhythm. This would, of course, include any metal in the mouth and most all jewelry, especially pierced jewelry.
