What effect does stress have on people's physical and mental health?

Stress is a psychobiological process, which is characterized by changes in psychological, behavioral and physiological response systems, leading to adaptation. Stress is caused by stressors, events or ideas. These stressors, time or thoughts will threaten, hurt or challenge the body, or will be beyond its coping ability. Stress can promote adaptation to the situation within a certain range, while too long or too much pressure may have adverse effects on physical and mental health. Factors affecting stressor evaluation or coping strategies may reduce adverse effects and promote adaptability, which is the focus of many treatment strategies to prevent or alleviate symptoms caused by stress.
