According to the National Psoriasis Foundation, about 10% of the population has the gene that could lead to Psoriasis. Having the gene does not mean you will have the disease. They believe that an external factor or trigger is what will cause the disease in someone that has the gene. Those triggers include but are not limited to: stress; injury to skin; certain Medications; and some infections.

According to the foundation, stress is a common trigger for psoriasis. The good news is that there are things you can do to help relieve stress. One is meditation. There are many types of meditation that you can try. The simplest maybe just sitting quietly for 15 minutes a day with your eyes closed, focusing only on your breathing. Give it a try. It costs nothing, and you have nothing to lose by trying. It may also help you sleep better.
Exercise is the next thing you can do to help you relieve stress. Again, this is a technique you can use without spending any month. Start small, maybe 10 minutes a day and slowly increase it to 60 minutes a day. You do not have to do all the minutes at once. Break it up over the day. Exercise releases endorphins that improve your energy and mood. It can also improve sleep and decrease anxiety.
