What field primarily studies the impacts of environmental factors on health?

The field that primarily studies the impacts of environmental factors on health is Environmental Health. This discipline focuses on understanding how various environmental exposures, such as air and water quality, chemical exposures, and living conditions, affect human health outcomes. Environmental health professionals assess, identify, and mitigate environmental risks to ensure public health safety and promote well-being.

While Public Health does encompass broader topics including health promotion, disease prevention, and health policy, Environmental Health specifically narrows in on the influence of environmental conditions on health. Epidemiology, on the other hand, is primarily concerned with the distribution and determinants of health-related events, focusing on the patterns and causes of diseases in populations, rather than directly assessing and addressing those environmental factors. Environmental Science studies ecosystems and the impacts of human activity on the environment, but does not solely focus on human health impacts as its core concern. Therefore, Environmental Health stands out as the most appropriate answer for this question, highlighting its specialized focus on the intersection of environment and public health.
