Climate change poses a significant threat to mental health, potentially increasing the rates of mental health adversities and disorders. Therefore, mental health professionals, including psychiatrists, play a crucial role in addressing and mitigating these consequences. The Philippines, as a highly climate-vulnerable nation, serves as an exemplary case highlighting the roles these professionals can undertake in the climate change response, including providing services, engaging in education and training, promoting mental well-being, and conducting surveillance and research, such as studies exploring the causal relationship between mental health outcomes and climate change.
