Psoriasis is a common skin condition that causes skin redness and irritation. Most people with psoriasis have thick, red skin with flaky, silver-white patches called scales. Psoriasis is very common. Anyone can get it, but it most commonly begins between ages 15 and 35. It is not contagious. You cannot spread it to others. Psoriasis seems to be passed down through families. Doctors think it probably occurs when the body’s immune system mistakes healthy cells for dangerous substances. Usually, skin cells grow deep in the skin and rise to the surface about once a month. In persons with psoriasis, this process is too fast. Dead skin cells build up on the skin’s surface. In general, psoriasis may be severe in people who have a weakened immune system. This may include persons who have AIDS, Autoimmune disorders (such as rheumatoid arthritis) and Cancer chemotherapy. Psoriasis can appear suddenly or slowly. Many times, it goes away and then comes back again and again.
Symptoms include irritated, red, flaky patches of skin, most often seen on the elbows, knees, and middle of the body and red patches may appear anywhere on the body, including the scalp. There is no known way to prevent psoriasis. Keeping the skin clean and moist and avoiding your specific psoriasis triggers may help reduce the number of flare-ups. Doctors recommend daily baths or showers for persons with psoriasis. Apart from that participation in vigorous exercise may reduce the risk of psoriasis by up to 30 per cent. Physical activity has been associated with a decreased risk of disorders characterized by systemic inflammation, including type 2 diabetes, colon cancer, coronary artery disease and breast cancer. Participation in at least 20.9 MET (metabolic equivalent task)-hours per week of vigorous exercise, the equivalent of 105 minutes of running or 180 minutes of swimming or playing tennis, is associated with a 25 per cent to 30 per cent reduced risk of psoriasis compared with not participating in any vigorous exercise.
Further, the most physically active women have a lower multivariate relative risk of psoriasis (0.72) compared with the least active. Walking is not associated with a reduced risk of psoriasis. Among the individual vigorous activities, only running and performing aerobic exercise or calisthenics are associated with a reduced risk of psoriasis. Other vigorous activities, including jogging, playing tennis, swimming and bicycling are not associated with psoriasis risk. In addition to providing other health benefits, participation in vigorous exercise may represent a new preventive measure for women at high risk of developing psoriasis.
