Abstract

The purpose of this review was to highlight the concept and understanding of physical stress and to discuss its Psychophysiological mechanisms along with characteristics and major causes. The environmental and physical changes that are responsible for alterations in the homeostasis of the body is simply identified as physical stress. The brain is to interpret experiences as alarming or non-alarming which trigger the physiological and behavioral responses in each situation. We gathered a literature data from different published articles, original research papers & online sources. We hypothesized that the continuous imbalances of physiological mechanism due physical and environmental stimulus can cause physical stress and it is concluded that the major factors of physical stress includes injury, excessive exercise, noise, pregnancy, workload, pressures and temperature with the involvements of psycho-physiological mechanism.
