Heatwaves directly threaten human health. Excessive heat exposure can lead to heatstroke, a condition where the body overheats and can't cool down, causing organ damage and even death. Heat exhaustion, dehydration, and worsening of pre-existing health conditions like heart disease and respiratory problems are also common.The elderly, children, and those with underlying health conditions are particularly vulnerable. Imagine a frail elderly person living alone in a poorly ventilated apartment during a heatwave. The lack of air conditioning and limited mobility can be a deadly combination. Heatwaves also exacerbate social inequalities, disproportionately impacting low-income communities who may lack access to proper cooling or healthcare facilities.
