I am wondering if stress causes a disruption in our perceptions, which then causes us to pick at our skin. When I am stressed, particularly when I am anticipating something, I am often more critical of myself. My perception becomes narrow and cynical to the point where I start picking my looks apart. The skin is an easy target because its constantly changing and experiencing breakouts. When I am feeling happy and preoccupied with thoughts, I overlook my imperfections and am much less interested in them. This year I chose to routinely exercise for 3 months and during that time I noticed that I picked much less than usual. What I also have noticed is that I pick more often during the winter months. Now I don't know if it is lack of vitamin D that causes an increase in skin picking. Wondering if anyone else picks more often during the winter months?
