Global Heatwave Health Risks and Urban Heat Trends

Overview

Medical experts continue to warn of the severe health impacts caused by rising temperatures. Clinical data indicates that respiratory complaints in emergency and outpatient visits have increased by 20% over the last two years, driven by air pollution, dust, humidity, and prolonged pollen seasons.

Heatwaves place significant strain on the cardiovascular and renal systems. While heat-induced vasodilation can lead to lower blood pressure, extreme heat and humidity can trigger stress responses resulting in sudden hypertension, increasing the risk of stroke and heart attacks. Cardiologist Dr. Cengiz Başar warned that patients should not alter medication dosages without consultation during these fluctuations. Research in ‘The Lancet’ associates rising temperatures and increased atmospheric pressure with higher stroke risks and mortality. Furthermore, experts emphasize that heart attack symptoms in women often differ from men, presenting as dizziness, nausea, shortness of breath, unexplained fatigue, or pain in the back and jaw. Prof. Dr. Hatice Betül Erer also noted the risk of Spontaneous Coronary Artery Dissection (SCAD) in younger women, which can be triggered by pregnancy, breastfeeding, or stress.

Beyond cardiovascular issues, summer activities present additional risks. Physical therapist Giorgos Goudévinos warned that sudden manual labor, such as gardening, can cause spinal injuries, knee damage, or tendonitis. Environmental hazards also include UV radiation, which causes sunburn and DNA damage. To manage heatwave discomfort, sleep specialist Dr. Jérôme Liotier recommends a routine including lukewarm showers before bed and keeping water nearby to prevent thirst-related disruptions. Urban environments exacerbate these risks through the heat island effect, where materials like asphalt and concrete trap heat, preventing nighttime cooling.
