Heat stress impacts workplace attitudes. Which statement best reflects this?

• A. Improved decision making
• B. No effect on mental performance
• C. Affects on attitudes
• D. Increased happiness

Answer: (C)

Heat stress can raise body temperature and cause fatigue, discomfort, and irritability. Those physical strains spill over into mood and how someone feels about their work, coworkers, and safety, shifting workplace attitudes. So describing the impact as affecting attitudes best captures the psychosocial effect of heat in the work environment.

The other ideas don’t fit as well because heat stress usually worsens cognitive performance and mood rather than improving decision making or happiness, and it generally has some effect on mental performance rather than no effect at all.
