Heat Stroke vs Exhaustion: Spotting the Silent Danger
20 Mar
Summary
- Heat exhaustion warns of body struggling with heat due to sweat and salt loss.
- Heat stroke exceeds 40C, potentially causing serious brain effects even mildly.
- Infants, elderly, athletes, and those on medication are at higher risk.
As summer heat intensifies across India, recognizing heat-related illnesses is critical. Heat exhaustion, characterized by heavy sweating and salt loss, serves as an early warning. If left untreated, the body's temperature regulation fails, potentially leading to heat stroke.
Heat stroke occurs when the core body temperature surpasses 40C. Even mild cases can silently affect the brain, causing confusion or irritability, which are often overlooked. Damaged brain proteins can begin to form early in severe heat exposure.
Key differences lie in body temperature and mental state. Heat exhaustion typically remains below 40C with alertness, while heat stroke exceeds this threshold and can cause disorientation. Heat exhaustion is reversible, but heat stroke is a medical emergency requiring immediate attention to prevent permanent injury.
Certain groups, including infants, the elderly, outdoor workers, athletes, and those on specific medications, are more vulnerable. Seeking immediate medical help for signs like confusion or seizures is paramount. Prevention includes regular hydration, avoiding peak heat, and wearing light clothing.
