Climate Change - Health (Effects)

Definition:

• Climate change has wide-ranging effects on human health, influencing disease patterns, heat-related illnesses, and mental well-being.

Effects of Climate Change on Health:

Heat-Related Illnesses:

• Rising temperatures can lead to heat exhaustion, heatstroke, and other heat-related illnesses, particularly in vulnerable populations.

Spread of Vector-Borne Diseases:

• Changes in temperature and precipitation can expand the geographic range of disease-carrying vectors like mosquitoes, leading to increased cases of diseases such as malaria, dengue, and Zika virus.

Food and Waterborne Diseases:

• Climate-related extreme weather events can contaminate water sources and disrupt food supply chains, increasing the risk of food and waterborne diseases.

Respiratory Problems:

• Air pollution and allergenic pollen levels can increase with climate change, leading to respiratory issues like asthma and allergies.

Mental Health Impact:

• Extreme weather events, displacement, and uncertainty associated with climate change can contribute to mental health problems, including anxiety and depression.

Increased Vulnerability:

• Vulnerable populations, such as the elderly, children, and those with pre-existing health conditions, are more susceptible to climate-related health risks.

Heat-Related Mortality:

• Prolonged heatwaves can result in excess heat-related deaths, especially in urban areas with inadequate cooling infrastructure.

Climate Change - Health (Effects)

Water Scarcity:

• Lack of access to clean drinking water due to droughts and water stress can lead to dehydration and waterborne diseases.

Displacement and Conflict:

• Climate-induced displacement can disrupt healthcare access and lead to increased health risks for affected populations.

Adaptation and Mitigation:

• Adaptation measures include improving public health infrastructure, early warning systems for heatwaves, and disease surveillance.
• Mitigation efforts focus on reducing greenhouse gas emissions to limit the extent of climate change and its health impacts.

Summary

• Climate change affects human health through heat-related illnesses, the spread of diseases, respiratory problems, mental health impacts, and increased vulnerability.
• Vulnerable populations are at greater risk of climate-related health risks.
• Adaptation and mitigation strategies are essential to protect public health in a changing climate.
