Stress and the weather?
In a study published in the January 2001 issue of Archives of Dermatology, researchers measured and compared the impact of psychological stress on the skin in students without psoriasis during three different stress level periods: after winter vacation, during final exams and after spring break. The researchers measured water loss in the students skin during these periods and found that during periods of stress, the skin’s ability to maintain a normal permeability barrier and retain water appears to be reduced.
