Getting sunlight and vitamin D does a lot of good to human body. Many people express how they often feel low and unwell when they are confined in close quarters for a long time and the best example for this is the Covid-19 pandemic, this is all because they lack vitamin D. But an unexpected condition that may benefit from vitamin D is psoriasis. Psoriasis is an autoimmune disease that causes dry and itchy patches on your skin. A study published in the Medicine suggests that if you don't have enough vitamin D, your body's defense system might act up, which could make psoriasis worse. Vitamin D is really important for keeping your bones strong and your body's defenses working well. It might also help your skin stay healthy. Scientists are looking into whether getting more vitamin D can help people who have psoriasis feel better. Another study published by Skin Pharmacology Physiology suggests that vitamin D is very important for our skin. It controls how skin cells grow, mature, and die, and it keeps your skin's protective barrier strong. It also helps your skin's immune system. If you don't have enough vitamin D, you're more likely to get skin problems like psoriasis and eczema.How Vitamin D Affect Skin Health?Some people with psoriasis have low levels of vitamin D. This could be because they try to stay out of the sun, which is how your body makes vitamin D. It's also possible that having low vitamin D can make your body's defenses go into overdrive, leading to psoriasis. Vitamin D also affects skin cells called keratinocytes, and if you don't have enough vitamin D, these cells might grow too fast, causing the thick, scaly skin that psoriasis is known for.Vitamin Deficiency: Who Is At Risk?People with psoriasis often have low vitamin D levels, but it's not always clear why. It could be because they don't eat enough vitamin D-rich foods, don't get enough sunlight, or have certain health problems. Older people, people who are overweight, babies, and people with dark skin are more likely to have low vitamin D. If you think you might have low vitamin D, your doctor can do a blood test to check. Taking too much vitamin D can be harmful. It can cause you to lose your appetite, pee too much, have heart problems, and have too much calcium in your blood, which can lead to kidney stones. Always talk to your doctor before taking vitamin D supplements.Right now, there's not a lot of proof that other vitamins or supplements can help with psoriasis. Some people believe that taking fish oil, which has omega-3 fatty acids, might help because it can reduce swelling. But there haven't been enough big studies to show if it really works. It's always best to talk to your doctor before trying any new vitamins or supplements for psoriasis
