Psychosocial risk is an ergonomic aggravator for the skeletal muscle system. The work shows how stress and exhaustion influence the outcome of a work. The week of March 9-15, 2020 was especially intense for me. The outbreak of cases of SARS-CoV-2 (Coronavirus or COVID-19) meant that during the 12th and 13th of March could not stop work activity, having started early morning with telephone calls, visits and managements until past the afternoon and beyond. Since then, the work has been intense until mid-May, affecting this situation on a psychological level.Stress has a physical effect on the tension in the muscles of the face, neck and back as a preparation for reacting to a stimulus that is dangerous and relaxes once it has passed. In the case of chronic muscles, it is constantly tense, which causes a decrease in blood flow to the muscles, thus reducing the supply of oxygen and nutrients, generating a greater accumulation of toxic waste and lactic acid. which entails a limitation of movement. Stress is involved in coordinating muscle groups while maintaining posture and balance during movement. This process involves headaches, chronic pain, contractures … so manual dexterity is also affected.
