Amid widespread heatwaves affecting many parts of the Northern Hemisphere, authorities and health experts have issued warnings to protect public health. Heat presents significant health dangers, ranging from symptoms like dizziness and thirst in cases of heat exhaustion to more severe conditions such as heatstroke, which can cause organ damage and even fatalities if left untreated. Experts have highlighted that as temperatures rise due to climate change, the likelihood of heat-related illnesses is expected to increase, particularly affecting vulnerable groups like infants, the elderly, and individuals with pre-existing health conditions such as diabetes or heart disease.

Extreme heat poses risks beyond direct health impacts. When high temperatures combine with humidity, sweating becomes less effective, increasing susceptibility to heat-related illnesses. Intense heat can also promote bacterial growth and water contamination, potentially causing diseases like cholera. Agriculture is at risk too, with heatwaves damaging crops and food security. Climate projections suggest global mortality rates could rise significantly by 2030 due to these risks, emphasizing the need for proactive measures. The timing and location of heatwaves worsen risks; early summer sees higher mortality as people haven’t acclimated, and regions unused to heat, like parts of Europe, face greater vulnerability. Countries have responded by limiting outdoor activities, establishing cooling centers, and advising the public to stay hydrated, avoid strenuous activities in peak heat, and monitor vulnerable groups like the elderly. Immediate medical attention for heatstroke is crucial for safeguarding public health during extreme heat.
