Heatwave Grips Europe, Straining Health Systems

Europe is grappling with an intense heatwave, leading to overwhelmed hospitals and numerous fatalities. Temperatures across the continent have soared, with projections indicating at least 150 million Europeans will experience heat above 35 degrees Celsius. This extreme weather poses significant health risks.

The human body struggles to maintain its core temperature of around 37 degrees Celsius. Initial responses include increased heart rate, sweating, and dilation of blood vessels in the skin. However, when these mechanisms fail, individuals may suffer from lethargy, headaches, fever, and sleep disturbances.

Dehydration is a major concern, as the body loses more fluid than it takes in. This affects blood circulation, reducing oxygen supply to vital organs like the kidneys. Elderly individuals and young children are particularly vulnerable, as they may not feel thirst as acutely or rely on others for hydration.

The most severe heat-related condition is heatstroke, occurring when the body's temperature exceeds 40 degrees Celsius. In such cases, the body conserves fluid and stops sweating, leading to darker urine. While the elderly are most at risk, young people have also sought hospital treatment for heatstroke during this wave. The homeless population faces additional challenges due to their living conditions.

Experts also warn of "tropical nights," where temperatures do not drop below 20 degrees Celsius, preventing the body from adequate cooling over a 24-hour period. Recommendations for coping include drinking plenty of water, staying in cool environments, taking cold showers, using air conditioning, and avoiding strenuous physical activity and alcohol.
