This podcast explores the unsettling effects of extreme heat on mental health, including increased anxiety, suicide rates, violence, and the impact on medication efficacy. It also discusses the relationship between heatwaves and suicide, the potential for a more violent future, finding hope in challenging times, and the urgency of addressing climate change and preparing for extreme weather.
Heatwaves can worsen mental health conditions and contribute to depressive phases, mania, and psychosis.
Hotter temperatures can lead to short-term and long-term increases in violence and aggression.

Heat's Impact on Mental Health
Extreme heat presents challenges for those with psychiatric conditions and the general population. It can exacerbate existing mental health conditions and contribute to depressive phases, mania, and psychosis. Medication effectiveness can be reduced, and increased irritability, anxiety, and stress are common. Heat also poses risks for suicide, with rates increasing as temperatures rise. Sleep disturbances, medication side effects, and poor nutrition further contribute to mental health challenges.
Heat's Impact on Violence
Hotter temperatures can lead to short-term and long-term increases in violence and aggression. Irritability and poor decision-making are common in uncomfortable heat, leading to higher rates of homicide, assault, and sexual violence. The perception of hostility in interactions is heightened, potentially leading to aggressive behavior. Indirect effects, such as food scarcity, economic instability, and environmentally-induced migrations, can also contribute to violence.
The Future Impact of Heat
As global temperatures continue to rise, experts predict a more violent future. Stressors on the economy and increased intergroup hostility may contribute to support for authoritarian regimes and anti-immigrant policies. Poor prenatal and postnatal nutrition resulting from climate impacts can lead to higher rates of criminality. Adapting to extreme heat and addressing climate change urgently are essential to mitigate the mental health and violence risks presented by rising temperatures.
