Step-by-step explanation:
Stress is an unavoidable part of life that can be brought on by both positive and negative events. It is a normal aspect of life and can be caused by experiences that require significant changes in a person's normal routines, whether these events are desirable or undesirable. These experiences, known as stressors, can be short-lived or persist over an extended period of time. They can include major traumatic events, significant life changes, daily hassles, and even close relationships with friends and family. The amount of resulting change in daily life can cause stress, and this stress can have physiological, cognitive, and behavioral responses. Although stress can be positive at times, it can also have negative health implications, contributing to the onset and progression of a variety of physical illnesses and diseases.
