Heat waves pose significant risks to human health, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Prolonged exposure to extreme heat can lead to heat exhaustion, heatstroke, and even death if not addressed promptly. High humidity levels exacerbate these risks by reducing the body's ability to cool itself through sweating. Urban areas, often referred to as 'heat islands,' are especially dangerous due to retained heat from concrete and asphalt surfaces. Awareness and preparedness are critical to mitigating these risks.
