Experts Link Heat Above 80F to Higher Aggression as Bodies Struggle to Stay Below 99F

3 articles · Updated · The Guardian · Jul 9

Summary

  • Upper-80s and 90s temperatures can raise irritability and aggression, with experts saying hotter days are also tied to more road rage, violence and mental-health ER visits.
  • 97F to 99F is the body’s target core range; to stay there, blood vessels widen, heart rate rises and sweating increases, which can lead to dehydration, fatigue, headaches and trouble focusing.
  • That physical strain can be misread as anger or distress, psychologists said, while poor sleep in hot weather further weakens stress tolerance.
  • 10am to 6pm is the hottest window experts advise avoiding; they recommend cooling breaks, water, fans, electrolyte packs and checking on children, older adults, pregnant people and those on medications that impair cooling.
