Extreme Heat Linked to Worsening Mental Health Conditions in U.S.
Extreme heat, a visible consequence of climate change, is significantly impacting mental health in the U.S., according to Christopher Drescher, associate professor in the Department of Psychiatry and Health Behavior at the Medical College of Georgia at Augusta University. Prolonged periods of high temperatures can exacerbate existing mental health conditions, increase emotional stress, and heighten risks for vulnerable populations. Drescher explains that heat affects the nervous system, leading to increased activity in the autonomic nervous system. Key impacts include disrupted sleep due to warmer nights, which in turn affects mood, anxiety, and emotional regulation. Dehydration is another immediate effect that can influence mood and overall well-being. Certain psychiatric medications can also decrease a person's tolerance to heat, making individuals on these medications more susceptible to adverse effects.
