Sunlight
A little natural sunlight is best for most people with psoriasis. However, in some cases, sun exposure can make their condition worse. It may cause additional symptoms such as burning and intense itching of the skin area involved.
So don’t forget to apply an SPF-15 sunscreen to protect your skin if you are going to be outside. Taking vitamin D and calcium supplement is also recommended as low sun exposure can make your body run short of these vital minerals and vitamin.
