Which of the following is a physiological symptom of stress?

• A. Sleep Pattern Changes
• B. Impatience
• C. Anxiety
• D. Memory Problems

Answer: (A)

When the body responds to stress, some reactions are physical changes in how the body functions. Sleep pattern changes are a physiological symptom because they show the body’s systems—often driven by stress hormones like adrenaline and cortisol and increased sympathetic activity—altering sleep itself, whether that’s trouble falling asleep, staying asleep, or sleeping too much. The other options describe non-physical effects: anxiety is an emotional state, impatience is a behavior, and memory problems are cognitive. So sleep pattern changes best represent a physiological sign of stress.
