What is the Stress?

Seal(1997) in “What is stress?” says stress is an emotional or physical reaction to demanding events or stimuli. There are many stressors, including disasters, the loss of a job and others. Hans Seyle, who is physiologist from Canada, has proposed that both humans and other animals react to any stressor in three stages, which are called by the general adaptation syndrome. There are three levels that are the alarm reaction, resistance, and exhaustion. The alarm reaction is physical metal response and resistance is adapting or escaping, and exhaustion is the organism breakdown or collapse. He did experiments about the general adaptation syndrome between rats and humans. As a result, the rats couldn’t predict about stress from problems, but humans could predict about stress. However, human could not perfect solve about stress because human’s stress reactions are various; stressors can change from person to person.
