What triggers the flight or fight response?

The flight or fight response is a physiological reaction that occurs in response to a perceived threat or alarming stressor. This instinctual reaction is part of the body’s natural defense system, initiating a cascade of hormonal changes that prepare an individual to either confront the danger or flee from it. When the brain perceives a threat, it activates the autonomic nervous system and prompts the adrenal glands to release adrenaline and other stress hormones. These hormones increase heart rate, enhance energy production, and redirect blood flow to muscles, among other changes, all aimed at improving the chance of survival in a threatening situation.

In contrast, positive social interactions, relaxation techniques, and routine daily activities generally promote feelings of safety and stability, inhibiting the activation of the flight or fight response. Therefore, it is specifically alarming stressors that trigger this instinctual response, marking the correct choice.
