Climate Change and Health

Climate change refers to long-term changes in temperature, precipitation patterns, and other atmospheric conditions on Earth, primarily driven by human activities such as burning fossil fuels, deforestation, and industrial processes. These changes have a profound impact on health, affecting both direct and indirect factors that influence human well-being. As global temperatures rise, they trigger a cascade of environmental changes that have direct and indirect consequences on human health. Below are key points regarding the effects of global warming on health and the strategies for mitigating climate-related health issues.

1. Global Warming and Its Effects on Health

a) Increased Heatwaves

  • Impact on Health: As global temperatures rise, the frequency and intensity of heatwaves increase. These extreme temperatures can lead to dehydration, heatstroke, cardiovascular stress, and exacerbate pre-existing health conditions such as respiratory and cardiovascular diseases.
  • Vulnerable Populations: Elderly individuals, children, low-income groups, and people with pre-existing health conditions are particularly at risk of heat-related illnesses.

b) Changes in Disease Patterns

  • Vector-borne Diseases: Warming temperatures expand the range of disease-carrying insects like mosquitoes and ticks. Diseases like malaria, dengue, Zika virus, and Lyme disease are spreading to new regions, impacting areas that were previously unaffected.
  • Water-borne Diseases: Rising temperatures and altered rainfall patterns can contaminate water sources, leading to the spread of water-borne diseases like cholera, dysentery, and typhoid.

c) Air Quality Deterioration

  • Impact on Respiratory Health: Higher temperatures contribute to the formation of ground-level ozone, a key component of smog, which worsens air quality. This increases the incidence of asthma, bronchitis, and other respiratory diseases, particularly in urban areas.
  • Pollution and Allergens: Climate change also exacerbates the spread of allergens like pollen, contributing to increased allergies and respiratory distress, especially during spring and summer.

d) Extreme Weather Events and Disasters
