Stress (psychology) I INTRODUCTION Stress (psychology), an unpleasant state of emotional and physiological arousal that people experience in situations that they perceive as dangerous or threatening to their well-being.
The word stress means different things to different people.Some people define stress as events or situations that cause them to feel tension, pressure, or negative emotions such as anxiety and anger.Others view stress as the response to these situations.Often people experience stress because of problems at work or in social relationships, such as a poor evaluation by a supervisor or an argument with a friend.Some people may be particularly vulnerable to stress in situations involving the threat of failure or personal humiliation.Also, your heart rate and blood pressure increase, and your immune system and memory are shaper.After you have dealt with the short-term stress, your body returns to normal.If your stress level increases or lasts for a longer time, you might experience other physical or emotional effects: These symptoms may also lead to loss of appetite, overeating and poor sleep, all of which can have serious consequences for your health.Usually these symptoms are minor and may be relieved through coping skills such as learning to relax, removing yourself for a time from the things that stress you out, and exercising.Chronic or long-term stress, however, poses a problem.If you repeatedly face challenges and your body is constantly producing higher levels of hormones, it doesn’t have time to recover.
