Climate Effects on Health

Climate change, together with other natural and human-made health stressors, influences human health and disease in numerous ways.

In the U.S., public health can be affected by disruptions of physical, biological, and ecological systems, including disturbances originating here and elsewhere. The health effects of these disruptions include increased respiratory and cardiovascular disease, injuries and premature deaths related to extreme weather events, changes in the prevalence and geographical distribution of food- and water-borne illnesses and other infectious diseases, and threats to mental health.

This webpage, developed by the Centers for Disease Control and Prevention, is dedicated to providing information and tools on the health effects of climate change.

The webpage is organized by Regional Health Impacts and by National Health Topics which include:

  • Air Pollution
  • Allergens and Pollen
  • Diseases Carried by Vectors
  • Food and Waterborne Diarrheal Disease
  • Food Security
  • Mental Health and Stress-Related Disorders
  • Floods
  • Temperature Extremes
  • Wildfires
