The Mental Toll of Extreme Heat: ASU Researchers Investigate Health Complications

Research has found that extreme heat can slow cognition, impair reaction time and focus, and increase anxiety. Studies have shown that cognitive performance declines as temperatures rise, potentially due to interrupted sleep and reduced activity in the parasympathetic nervous system. Heat has also been linked to decreased productivity in the workplace and poorer performance on standardized tests. Additionally, heat can induce moodiness and irritability by raising cortisol levels and triggering a stress response. Staying well-hydrated is crucial in mitigating the effects of heat on mental wellbeing.
