Heat Triggers Physiological and Psychological Responses, Experts Explain

Psychologists and physiologists have detailed how high temperatures affect the body and mind, linking heat to increased irritability and aggression.

• Dr. Craig Sawchuk of Mayo Clinic said the body responds to heat by dilating blood vessels and sweating, which can cause dehydration and impair concentration.
• Clinical psychologist Susan Albers noted that rates of road rage, violent incidents, and emergency visits for psychological issues rise on hot days.
• Kim Meidenbauer, psychology professor at Washington State University, stated that physical discomfort from heat and sleep disruption reduce people's tolerance for stress.
