Which of the following is NOT a Self-Imposed Stressor?

• A. Drugs
• B. Exhaustion
• C. Hypoglycemia
• D. Altitude

Answer: (D)

Self-imposed stressors are factors you bring on yourself through your actions or choices, which increase the body’s workload and can degrade performance. Drugs, exhaustion, and hypoglycemia fit this idea because they stem from decisions or neglect of self-care that directly affect mental or physical function.

Altitude, on the other hand, is an environmental condition you encounter rather than something you choose to create. It imposes physiological stress (less oxygen, lower pressure, potential hypoxia) regardless of your actions, so it’s not considered a self-imposed stressor. In a UH-60 context, you manage altitude-related stress with proper procedures such as oxygen use and acclimatization, but the stress itself isn’t produced by your own choices.
