Chronic stress

response to emotional pressure suffered for a prolonged period of time in which an individual perceives they have little or no control

Chronic stress is stress that happens over a long period of time. It is different than acute stress, which happens over a short period of time and then goes away.

Stress is a normal part of every living thing's daily life. However, when stress becomes chronic, it can damage the body and the mind. When a person (or animal) is stressed, the body reacts in certain ways - for example, by releasing chemicals called corticosteroids.[1][2] If this happens again and again, over a long period of time, it can change the way the brain works.[3][4] These changes can damage working memory[5] spatial memory,[5] and decision-making skills.[6] They can also increase aggression.[7]

Chronic stress can cause (or worsen) many different medical problems. For example, people who have had chronic stress are more likely to get hypertension (high blood pressure) and heart disease.[8]
