Which type of stressor refers to persistent, background factors like noise and pollution?

• A. Major Life Event Stressor
• B. Ambient Stressor
• C. Catastrophic Stressor
• D. Acute Stressor

Answer: (B)

Ongoing environmental pressures act as ambient stressors, representing the persistent background factors in daily life. These are not one-off events but continual conditions that keep the body's stress response activated at a baseline level. Noise, pollution, and crowding steadily contribute to chronic arousal, which can accumulate over time and affect health and well-being through mechanisms like increased cortisol release and higher allostatic load. This differs from acute stressors, which are brief and tied to a specific moment or incident; major life events, which are significant but discrete changes; and catastrophic stressors, which involve large-scale disasters. So, the term that best captures these persistent, background pressures is ambient stressor.
