Health Impacts of Flooding

by Kaylee Anderson

An effect of climate change is an increase in the occurrence of floods. Particularly, in Canada flooding is five times more frequent than the occurrence of the next most common natural disaster. In addition to the obvious risk of drowning, toxin and pathogen exposure, and stress increase during flooding. A past study by Nakamura, et al. (2012) revealed an association between acute cardiovascular disease and natural disasters, such as the Japanese tsunami in 2011. Vanasse et al. (2016) examines the effect of flooding on acute cardiovascular disease in Saint-Jean-sur-Richelieu. Continue reading

Climate Change Impacts Human Health






by Kaylee Anderson

Climate change has been found to play a role in many health issues across the globe because of the broad range of its effects on the environment.Franchini et al. (2015) do a current review showing that the increased temperatures, greater frequency of extreme weather events, increased air pollution, decreased safe water, and lower crop yields are only some of the impacts on our planet. The impact on these resources can be correlated which many public health issues. Extreme weather events, such as heat waves, affect several components of health, including, higher morality and greater susceptibility to chronic respiratory and cardiovascular disease and can also exacerbate pre-existing respiratory and cardiovascular diseases. Heat waves are typically associated with drought, contributing greatly to the occurrence of wildfires, and therefore, increases in smoke emissions, which are correlated with increased hospital admissions for respiratory and cardiovascular problems.

Additionally, drought and heat have adverse effects on food production. Many low-income countries are seeing higher death rates of children under 5 due to malnutrition-induced pneumonia. In low-income countries, the drought forces lesser quality of hygiene, which ultimately increases the frequency of diarrheal diseases.

Lastly, the air quality worsens due to particulate matter, which can enter the blood stream and increase premature mortality. Aeroallergens are also more prevalent, which has led to more allergy-related hospitalizations and higher rates of allergic sensitization.

Ultimately, climate change influences a broad range of health issues, including nutrition, infectious diseases, allergies, and cardiovascular disease.
