Impacts of climate change on health

Climate change leads to more frequent and severe extreme weather events such as heatwaves, hurricanes, floods, and wildfires, causing direct injuries, fatalities, and long-term health effects.

Extreme Weather Events

Rising temperatures increase the risk of heat-related illnesses such as heat exhaustion, heatstroke, and dehydration, particularly among vulnerable populations.

Heat-related Illnesses

Climate change exacerbates air pollution, worsening respiratory conditions such as asthma and COPD, and increasing the risk of cardiovascular problems and premature death.

Air Pollution

Changes in temperature and precipitation patterns alter the distribution and behavior of disease-carrying vectors, leading to the spread of vector-borne diseases like malaria, dengue fever, and Lyme disease.

Vector-borne Diseases

Climate-related disruptions to food and water systems contribute to malnutrition, foodborne illnesses, and waterborne diseases, particularly in vulnerable communities with limited access to resources.

Food and Water Insecurity

Climate change exacerbates social and economic inequalities, leading to social disruption, displacement, and conflict. Disrupted communities may experience heightened stress, trauma, and violence, further impacting mental and physical health outcomes.
