Climate Change and Health


How does climate change affect human health?

“While climate change is a global process, it has very local impacts that can profoundly affect communities. It can affect people's health and well-being in many ways, some of which are already occurring, by:

  • Increasing the frequency and severity of heat waves, leading to more heat-related illnesses and deaths.

  • Changing the range of disease-carrying insects, such as mosquitoes, ticks, and fleas that transmit West Nile Virus, dengue fever, Lyme disease, and malaria to humans.

  • Increasing exposure to pollen, due to increased plant growing seasons; molds, due to severe storms; and air pollution, due to increased temperature and humidity, all of which can worsen allergies and other lung diseases, such as asthma.

  • Increasing temperatures and causing poor air quality that can affect the heart and worsen cardiovascular disease.

  • Increasing flooding events and sea level rise that can contaminate water with harmful bacteria, viruses, and chemicals, causing foodborne and waterborne illnesses.

  • Increasing the frequency and severity of extreme weather events, in addition to causing injuries, deaths, illnesses, and effects on mental health from damage to property, loss of loved ones, displacement, and chronic stress.

  • Placing added stress on hospital and public health systems, and limiting people's ability to obtain adequate health care during extreme climate events.” (Source: Text from NIEHS Webpage) [Full Report Click Here]
