As frustrating as they can be, allergic hypersensitivities are just another one of the multiple ways your body protects you from threats. Metal allergies–especially from nickel, cobalt, chromium, and zinc–are caused when molecules of metal are picked up by the skin and the immune system views these foreign objects as threats. Aside from jewelry, an allergic reaction to metal can also be triggered by other everyday things like watches, coins, and sometimes even cosmetic products.
Metal sensitivity is definitely not an uncommon occurrence, as it is said that 10 to 15% of the population experience symptoms of various kinds, some more chronic than others. Exposure for prolonged periods to these metals when sensitive can cause more severe reactions like inflammation or muscle pains. It may even develop into wedding ring dermatitis if not paid attention to properly. Identifying these metal sensitivities is important, because the last thing you want is a lifelong wedding band that gives you rashes and hives.
