 Psoriasis is a condition characterized by scaly, red and raised patches on the skin, especially on the elbows, knees and scalp. Psoriasis often causes itching, burning and stinging in affected areas. Scientists do not know what exactly causes psoriasis. They believe that genetics and the immune system are contributory factors to the development of psoriasis. In common and layman terms, the life cycle of skin cells increases, causing the buildup of excess skin cells to form the red patches and scales. Psoriasis tends to go through cycles, flaring for a few weeks or months, then subsiding for a while. It can be triggered by infections, skin injuries and heavy alcohol consumption. Other triggers include vitamin D deficiency, stress, emotional trauma, certain medications and smoking. Misinformation about psoriasis can contribute to misunderstanding and confusion. Let's clarify seven common misconceptions about psoriasis. 1. Psoriasis is not contagious. It's an autoimmune condition that occurs due to an overactive immune system, not from any contagious factor. 2. Psoriasis is not just a skin condition. It is an autoimmune disease that affects the skin, but it can also have systemic implications, potentially affecting joints, nails and other organs. 3. Psoriasis is not caused by poor hygiene. It is a complex condition influenced by genetic and immune system factors, not by cleanliness. 4. There is no known cure for psoriasis, but the condition can be managed effectively through various treatment options to control symptoms and improve quality of life. 5. Psoriasis does not only affect older people. It can develop at any age, from infancy to old age. It is not limited to any specific age group. 6. Psoriasis is not primarily a cosmetic concern. It can, in fact, cause significant physical discomfort, including itching, pain and inflammation. It can also impact mental and emotional well-being due to its visible nature. 7. Sun exposure cannot cure psoriasis, but it may improve psoriasis symptoms for some individuals. Sun exposure should be approached with caution, as excessive exposure can worsen the condition and increase the risk of skin damage. If you think you may suffer from psoriasis, remember, when it comes to any health issues, it is always paramount to consult medical professionals to get information that applies specifically to the individual involved.
