When temperatures rise above 30 degrees, immediate concerns focus on surviving the hottest part of the day. However, experts caution that the danger persists even after a heat wave subsides, as the body can sustain severe complications even as temperatures return to normal. Prolonged exposure to extreme heat can lead to fatal outcomes, paralysis, or death within a week.
Several groups are at heightened risk during these periods, including the elderly, individuals with chronic illnesses, pregnant women, young children, and outdoor workers. Nevertheless, even healthy individuals can be negatively affected by sustained heat exposure. During a heat wave, the body attempts to overcompensate by lowering its normal core temperature.
This process results in significant losses of both water and essential electrolytes. To manage this fluid loss, the heart must pump with increased effort. This added strain on the cardiovascular system can lead to critical and potentially fatal consequences.
Therefore, awareness of the risks extends beyond the peak heat of the day and requires vigilance until normal conditions are fully restored.
