About Heatstroke

• It occurs when high ambient temperature prevents sweating to regulate body temperature.
  • Ambient means relating to the immediate surroundings.
• Core body temperature rises to 40 degrees Celsius.
• Severe imbalance of salts like sodium and potassium occurs in the body.
• Symptoms include fogginess, drowsiness, coma in severe cases, kidney and liver damage. Heat stroke can lead to death due to organ disruption.
• Immediate Treatment: The priority is to lower core body temperature quickly. Methods include pouring cold water, drinking cold drinks, and ingesting electrolytes.
• High-Risk Groups: Special attention is needed for the elderly, young, and those with comorbidities. It can occur at any age, not limited to specific demographics.

Preventing Heat Stroke

• Avoid direct sunlight, especially from noon to 3 pm. Minimise strenuous activities during these hours.
• Stay hydrated by drinking water regularly. Consume hydrating fluids like lassi, lemon water, ORS, etc.
• Avoid alcohol, tea, coffee, and carbonated drinks as they dehydrate.
• Wear lightweight, light-coloured, loose cotton clothes.
• Lower body temperature by using damp cloths or taking cold baths.

Significance of Humidity and Night-Time Temperatures

• High humidity makes perceived temperatures higher than actual ambient temperature. Sweat doesn’t evaporate effectively in high humidity, reducing the body’s ability to cool down.
• High night temperatures prevent the body from resting and recovering.
• Lower night temperatures allow the body to recover and recoup from heat exposure.
