The debate over whether or not mobile phones can damage your brain is far from over, with experts on both sides of the argument failing to come to any kind of agreement. But there may be other dangers involved, especially if you're the type of person who lives on your mobile.
Nickel is a common cause of contact allergy - that is, an allergy to a substance that you touch (as opposed to something you breathe in or eat). Experts reckon 17 of men.
And it's not just mobiles that cause the problem. Metal jewellery that's not made from silver, gold or platinum, for instance, or watches or glasses frames can all contain nickel. And while things such as keys, coins and paper clips contain nickel too, they don't usually trigger an allergy because any contact you have with them is usually brief.
Using a cover on your phone, using earphones or switching to a phone that has no metal parts on its surface could help if you do develop a problem.
Is there no end to the substances that cause allergies? Hair dye, for instance, can be extremely dangerous if you develop an allergy to it.
