One contributing factor to stress reactions is the physical factor. Which option is associated with this factor?

• A. Sleep deprivation
• B. Worries about others
• C. Noise exposure
• D. Hunger or thirst

Answer: (B)

Stress reactions can be amplified by physical factors—conditions the body itself experiences. Sleep deprivation is a clear example because not getting enough rest directly alters brain function, hormonal balance, and overall arousal, making stress harder to manage. Worries about others is a psychological stressor, not a physical one. Hunger or thirst and noise exposure are also physical factors, but sleep deprivation most directly demonstrates how a lack of rest heightens stress responses.
