Acute Stress: This is the most common and it comes from events of the recent past or those anticipated in the near future. These are primarily the daily events of life: The fender bender. Missing the commuter train.  A big mistake at work. Losing cable TV during the Super Bowl. And so on. Today there are also many psychological “threats” to contend with. For example: Moving, divorce, troubles or challenges at work, exams at school.

A form of acute stress is “eustress” which can be defined as a form of positive stress.
