Doctors have discovered that some of our most beloved items might be making us itch. It seems that many of our tech toys—iPads, iPhones, laptops, cell phones, video game controllers—include nickel in their cases.

Luckily, all you have to do is put them in one of those protective cases, and that seems to help most sufferers. If not, consider mittens.
