WHO Highlights Rising Health Risks from Extreme Heat Due to Climate Change
• The World Health Organization (WHO) has released a detailed fact sheet on the growing health risks associated with extreme heat, exacerbated by climate change. According to the report, heat stress is a leading cause of weather-related deaths and can worsen pre-existing conditions such as cardiovascular disease, diabetes, and respiratory illnesses. Vulnerable populations, including the elderly, outdoor workers, and those in low-quality housing, are particularly at risk. The frequency, intensity, and duration of heatwaves are increasing globally, with significant impacts on public health, labor productivity, and essential services. WHO emphasizes that heat-related mortality has risen sharply, with an 85% increase in deaths among people over 65 years old between 2000–2004 and 2017–
• The organization also highlights the need for urgent climate action and public health interventions to mitigate these risks.
Why It's Important?
Extreme heat poses severe risks to human health, particularly for vulnerable groups such as the elderly, children, and individuals with chronic illnesses. Heatwaves can lead to heat exhaustion, heatstroke, and exacerbation of existing health conditions. Urban areas, with their lack of green spaces and heat-retaining infrastructure, are especially susceptible. Additionally, heatwaves can disrupt essential services like healthcare, power, and transportation, further compounding risks. The WHO notes that heat-related deaths are preventable with proper planning and interventions, but awareness among the public and health professionals remains insufficient.
