During a heat wave, stagnant atmospheric conditions (where air doesn't move much) and poor air quality significantly worsen heat-related illnesses.
Stagnant air traps pollutants, leading to higher concentrations of harmful substances like ozone and particulate matter. When combined with high temperatures, these pollutants can exacerbate respiratory and cardiovascular stress, making it harder for the body to cool itself and increasing the risk of heat exhaustion, heatstroke, and other severe health impacts
