How does acute stress differ from chronic stress?

Acute stress is characterized as a reaction to specific and immediate threats or challenges, often referred to as "fight or flight" responses. This type of stress occurs in response to events such as a sudden exam, an argument, or an accident, where the individual experiences heightened alertness, increased heart rate, and quickened breathing. It is short-term and typically resolves once the threat or challenge is removed.

On the other hand, chronic stress is ongoing and accumulates over time due to prolonged exposure to stressors such as ongoing work pressures, relationship problems, or financial difficulties. This type of stress can lead to various health issues and can be more debilitating because there is no clear resolution or end to the experience of stress.

The distinction highlighted in the chosen answer emphasizes the nature and duration of the stimuli involved: acute stress is a direct response to specific events, while chronic stress results from persistent circumstances that do not resolve, contributing to a different psychosocial impact.
