Nickel is literally found everywhere. Your cellphone? Yes. Kitchen utensils? Yes. Even some of your gold, silver, and diamond high-end jewelry may contain traces of nickel. And of course, the five cent coin is obviously made of nickel too. Since this silvery metal is commonly found in so many household products, the number of people who suffer from nickel allergies increases each year. Someone with such an allergy may experience an itchy, red, and inflamed rash known as dermatitis or eczema after their skin comes in contact with the metal. Earlobes, wrists, and the lower abdomen are typically affected. But in recognition of this increasing sensitivity, many manufacturers now offer nickel-free alternatives for most products, and if you’re unsure whether your brand-new toaster is made of this pesky ingredient, you can buy a nickel test at your local pharmacy and do at-home testing.
