Which group of stressors includes environmental factors?

The correct choice identifies physiological stressors as those that encompass environmental factors. This category includes stressors that are directly related to the body and its responses to external stimuli, such as temperature extremes, altitude changes, noise levels, and other physical conditions found in the environment.

These physiological stressors can impact the body's functioning and require adaptations, which is why they are considered in the context of aeromedical concerns. For example, in aviation settings, pilots may encounter shifts in atmospheric pressure, temperature variations, or turbulence, all of which can provoke physiological responses.

In contrast, psychosocial stressors refer to the emotional and social pressures one may experience, cognitive stressors involve mental processes such as decision-making and problem-solving, and genetic stressors pertain to inherited traits or predispositions affecting health. While these other categories certainly affect an individual's overall well-being and performance, they do not specifically include environmental factors, which is the core of physiological stressors.
