World health day is a global health awareness day, taking place every year on 7th April, under the sponsorship of the World Health Organization (WHO).

The theme of 2024 is My health, my right. Humans have the right to access, clean water, good health services, clean air, good nutrition, quality housing and good working and environmental conditions.

Globally, millions of people’s health is at risk from tragic events of conflicts, disease pandemics and climate change, and this campaign calls on world leaders to ensure the population has access to the appropriate healthcare and living conditions.

Climate change is directly contributing to health emergencies around the world, including:


  • Heatwaves – they can cause exhaustion, dehydration, and strain on our cardiovascular system.


  • Poor air pollution – can cause chronic respiratory conditions and can worsen allergies.


  • Wildfires – can cause poor air quality, and chronic respiratory conditions with smoke inhalation.


  • Floods – can cause dangerous environments around our homes and can contaminate our freshwater sources with diseases like e. Coli and cholera.


  • Tropical storms – can cause physical injuries, environmental damage and negative mental health effects like anxiety, stress, and depression due to the lasting effects.


Addressing climate change can help reduce the impact it has on our physical and mental health. The NHS is the first healthcare provider globally to commit to tackling climate change through more sustainable healthcare.
