Political polarization and health.

In addition to social determinants of health, such as economic resources, education, access to care and various environmental factors, there is growing evidence that political polarization poses a substantial risk to individual and collective well-being. Here we review the impact of political polarization on public health. We describe the different forms of polarization and how they are connected to health outcomes, highlighting the COVID-19 pandemic as a case study of the health risks of polarization. We then offer strategies for mitigating potential harms associated with polarization, with an emphasis on building social trust. Finally, we propose future research directions on this topic, underscore the need for more work in a global context and encourage greater collaboration between social scientists and medical scientists. We conclude that polarization is a serious-if largely overlooked-determinant of health, whose impacts must be more thoroughly understood and mitigated.
