Last week I and my friends from high-school went to the pool. One of my friend has psoriasis on his back, and when the lifeguard noticed it he asked him to leave the pool because he has skin disease that may spread to the other people swimming in the pool. We told him it is psoriasis and not some fungus, but he told us that psoriasis is also infectious. Is that true? Can psoriasis infect people who come in touch with people with psoriasis? Can I go swimming with him or should be more cautious? A. I’m sorry to hear about your friend’s bad experience. People can be so mean and bad, and it’s even worse when they think they’re right when they behave like that. Your friend can’t make you have psoriasis, no matter how much he’ll touch you, so you can go swimming with him with out any worries. Q. Can I catch pneumonia, if I go outside with wet hair? My Mother used to tell me when I was a kid that if I go outside with wet hair, I will catch pneumonia. Is this true? A. IF YOUR WET WATER REMOVES MORE HEAT FROM THE BODY FASTER THAN WHEN YOUR DRY ALSO CONSIDER THAT HEAT RISES WE LOSE MOST OF THE TOP OF OUR HEADS WHEN YOU ADD WATER YOU DRAMATICLY LOWER YOUR TEMPERATURE ON YOUR HEAD AND ALSO CONSIDER THAT IF YOUR MOVING FROM A COLD PLACE TO A WARM PLACE SEVERAL TIMES A DAY LIKE A FREEZER ON A HOT SUMMER DAY OR INDOORS TO OUT DOORS IN THE WINTER TIME 20 MINUTE INTERVALS I WILL SAY YES YOU CAN CATCH COLD AN GET THE SNIFFLES, COUGH AND OR SORE THROUGHT BUT I DO AGREE THAT YOU WON'T NECISARLY GET PENOMNIA FROM JUST WET HAIR ALONE THERES MANY MORE FACTORS FOR THAT. Q. Are cold sores contagious? My boyfriend has cold sores on his mouth. Can I catch it from him? If so, how can I prevent catching it? A. The virus that causes cold sores is known as the herpes simplex virus (HSV). There are two types of HSV, type I and type II. Cold sores are usually caused by type I. Herpes simplex infections are contagious. You can catch the virus by kissing your boyfriend or having other close contact with his sores or even from having contact with other parts of his skin that appear normal but are in fact shedding the virus. People are most contagious when they have active blister-like sores. Once the blisters have dried and crusted over (within a few days), the risk of contagion is significantly lessened. Therefore, it is best that you don't come in physical contact while he has the cold sores, since he is contagious. However, a person infected with HSV can pass it on to another person even when a cold sore is not present. This is because the virus is sometimes shed in saliva even when sores are not present.
