Why do I sometimes get cold sores in my mouth? Are they really related to stress?

Dear George:



It sure sounds scary, but herpes simplex is a very common infection that strikes many people. And chances are it's the main suspect behind those small, really annoying blisters on or around your mouth or nose. This infection is caused by a virus known as herpes simplex type 1, which stays in your system after an initial outbreak and lurks in nerve cells until something triggers another eruption. Sometimes it's tough to pinpoint what that trigger is, but medical experts say sunlight, fever, stress, hormonal changes and foods like nuts, chocolate and certain varieties of grains are among the usual suspects.

While it's polite to share in most social situations, herpes simplex is one thing you'd best keep to yourself. Until your blisters heal, it's very contagious. You can easily spread the virus if you touch things with the same fingers that have touched a cold sore. Though it's not a serious threat to your health in most cases, you can spread the infection to your eyes that way, so be sure to snub the urge to rub.

Sure, it's easy to feel like a sore loser with a mouth full of painful little blisters. But it's also easy to avoid them in the future. Eating a well-balanced diet, getting enough sleep and managing the stress in your life will all empower your mind and immune system to be back in fighting form. If you've already got those blistery blues, be sure to wash your hands frequently and avoid kissing--your loved ones will love you even more if you do.

Signed,

Wendell
