| Summary/Abstract |
This paper provides the first study to explore the relationship between exposure to ambient temperatures during pregnancy and adolescent mental health in China. The results show that experiencing one more hot day relative to local historical contemporaneous average values during pregnancy significantly increases the likelihood of mental health disorders in adolescence. The impact is larger in the first and second trimesters. Individuals born in the northern region and whose mothers work in agriculture are more vulnerable to high temperatures. Prenatal exposure to hot days is more harmful to the mental health of older adolescents. Additionally, the adverse effects are similar for both men and women and individuals with rural and urban hukou. Biological effects, income effects, and human capital accumulation might be three operative channels of the impact. These findings add to the evidence on the lasting health effects of early life exposure to climatic shocks and call for policy interventions during pregnancy.
