How Climate Change is Impacting Public Health in 2025: Risks
As we move further into 2025, the impacts of climate change are becoming more apparent, and public health is at the forefront of these challenges. From extreme heat waves to shifting disease patterns, climate change is influencing a variety of health risks in ways we may not have anticipated. In this blog, we will explore how climate change is affecting public health.
1. Rising Temperatures and Heat-Related Illnesses by climate change
One of the most immediate health impacts of climate change is the increase in heatwaves, which have become more frequent and intense in recent years. In 2025, these heatwaves are not just uncomfortable; they can be deadly. Extreme heat can cause heat exhaustion, heatstroke, and even death, especially among vulnerable groups like the elderly, children, and people with pre-existing health conditions.
Impact on Public Health:
- Heat-related illnesses: Prolonged exposure to extreme heat can lead to dehydration, organ failure, and heatstroke.
- Worsening cardiovascular conditions: Heat puts additional strain on the heart, making it harder for those with heart conditions to cope.
2. Air Pollution and Respiratory Diseases
The rising temperatures also contribute to worsened air quality. Higher temperatures increase the production of ground-level ozone, a major component of smog. In 2025, this means that asthma, bronchitis, and other respiratory diseases are becoming more common, particularly in urban areas.
Impact on Public Health:
- Increased asthma and COPD: The worsening air quality exacerbates conditions like asthma, COPD (chronic obstructive pulmonary disease), and other respiratory illnesses.
- Higher hospital admissions: More people are being admitted to hospitals for respiratory issues, putting additional strain on healthcare systems.
3. How Climate Change is Spreading Infectious Diseases
馃實 Did you know? Climate change is making it easier for infectious diseases to spread!
馃 Mosquitoes & Ticks on the Move
Warmer temperatures are expanding the habitats of mosquitoes and ticks, allowing them to spread diseases like malaria, dengue fever, and Lyme disease to new regions. 馃實馃毇馃 Stay informed and take precautions!
馃搷 New Areas at Risk
Regions that were once too cold for these diseases may soon experience outbreaks. As global temperatures rise in 2025, more communities could face new health threats.

Impact on Public Health:
- Vector-borne diseases: Warmer temperatures allow mosquitoes and ticks to thrive in areas they previously couldn鈥檛, bringing new disease risks to new regions.
- Healthcare strain: The spread of infectious diseases places added pressure on healthcare systems that are already grappling with climate-related health issues.
4. Mental Health Effects of Climate Change
While the physical health impacts of climate change are often highlighted, the mental health consequences are equally concerning. The stress of living through natural disasters, displacement, and uncertainty about the future is taking a toll on mental health in 2025. Climate anxiety and depression are on the rise, particularly in communities hardest hit by climate-related disasters.
Impact on Public Health:
- Climate anxiety and depression: The ongoing news about climate disasters, coupled with the fear of an uncertain future, is leading to widespread mental health issues.
- Post-traumatic stress disorder (PTSD): People who have experienced climate-induced disasters (like hurricanes, floods, or wildfires) may develop PTSD.
5. Food and Water Security
Changes in precipitation patterns, prolonged droughts, and extreme weather events are all contributing to disruptions in food and water supply chains. In 2025, these disruptions are expected to become more severe, leading to food insecurity, malnutrition, and waterborne diseases. Communities in drought-prone areas are at particular risk.
Impact on Public Health:
- Malnutrition: With unpredictable crop yields and reduced access to nutritious food, many regions face increased rates of malnutrition.
- Waterborne diseases: Droughts and floods can contaminate water sources, leading to an increase in waterborne diseases like cholera.

Heatstroke Deaths in 2024: A Growing Global Crisis
In 2024, heatwaves intensified by climate change led to significant heat-related fatalities worldwide. In India, between March and June, 733 heatstroke deaths were reported across 17 states, with over 40,000 suspected cases.

Conclusion: A Call for Action in 2025
The effects of climate change on public health are clear and worsening as we move further into 2025. From heat-related illnesses to the spread of infectious diseases, the toll on human health is significant. However, there are solutions available to mitigate these effects. Governments, healthcare systems, and individuals must work together to create climate-resilient communities, improve public health infrastructure, and reduce carbon emissions to protect future generations.
As we continue to address the global climate crisis, prioritizing public health is crucial. By taking action now, we can safeguard the health of millions and build a more sustainable, resilient future.
