The three types of stress are acute stress, episodic acute stress and chronic stress, according to the American Psychological Association. Diverse characteristics, symptoms and treatment methodologies typically occur within these three categories. The cause and duration of symptoms of stress help define the type of stress an individual experiences.
Births, deaths and personal losses comprise major life changes that may lead to stress, according to Mayo Clinic. A physically or emotionally uncomfortable environment may induce stress. Sometimes uninvited guests or unexpected expenses cause stress. Work-related stress includes personality clashes or relentless and urgent demands or deadlines. Social obligations such as meeting strangers or negative family interactions may also cause stress.
