Stressor

Stressor (/ˈstrɛsɔːr/) is a chemical or biological agent, environmental condition, external stimulus or an event that causes stress to an organism. Stressors are capable of producing both physical and psychological stress.

Etymology

The term "stressor" is derived from the word "stress", which originates from the Middle English "destresse", meaning "hardship" or "affliction". The suffix "-or" is used to denote an agent or something that performs a particular action.

Types of Stressors
