The Psychological Toll of Heat: The Effects of Temperature on Mental Health in Mexico Climate Health — with Antonia Vazquez — Draft

High temperatures worsen mental health, yet evidence from low- and middle-income countries is limited. Using nationwide administrative and survey data from Mexico, we estimate the effects of heat on self-reported well-being, mental illness emergency visits, and suicide. Comparing hotter and cooler weeks within locations, one extra day above 30°C (86°F) increases suicides by 3.2% and emergency visits by 2.4%, while lowering well-being. Effects are larger than in the U.S. but smaller where psychiatrist access is higher. Women’s visits rise more, whereas suicide effects concentrate among men, underscoring mental health as a critical and unevenly protected dimension of climate-related harm.

I provide evidence on the detrimental effect of in utero exposure to heat and humidity on children’s health at birth in Mexico. Effects are larger when accounting for humidity, and mitigated by air conditioning adoption.
