Stress is the response of our body to a challenge or demand. It is the physical, emotional, and mental response to a situation that requires us to adapt or change. Stressor, on the other hand, is the external event or situation that triggers our stress response. It is the cause of stress.

Stress is your hormonal response to a perceived threat, danger, or other stimuli. Stressors are what trigger this reaction. Stress can involve emotional reactions like panic, irritability, or worry. Stressors are the experiences that prompt those feelings.

But do you know what the difference is between "stress" and "stressors?" Stressors are situations that are experienced as a perceived threat to one’s well-being or position in life, especially if the challenge of dealing with it exceeds a person’s perceived available resources.
