Stress (biology)

Stress is an organism’s response to a stressor such as an environmental condition or a stimulus. Stress is a body’s way to react to a challenge. According to the stressful event, the body’s way to response to stress is by the sympathetic nervous system which results in the Fight-or-Flight response. Stress typically describes a negative condition or a positive condition that can have an impact on an organism’s mental and physical well-being.
