Be Alert with Heat Stroke

To prevent unintended incidents, it is advised that the public be vigilant for the early signs of heatstroke, particularly in children and the elderly.

A heat stroke is defined as a potentially fatal condition marked by a core body temperature that is higher than 40°C and central nervous system dysfunction that causes delirium, convulsions, or coma.

Heat-related illnesses can range in severity from mild to severe as shown in the table below.

Severity Types Definition

Mild Prickly heat Small, raised, itchy rash that appears in places where sweat collects.
Mild Heat cramps Painful muscle spasms that occur due to dehydration and loss of nutrients from excessive sweating. Heat cramps are most common in the abdomen, back, arms, or legs.
Mild Heat syncope Heat syncope is a fainting (syncope) episode or dizziness due to dehydration and lack of acclimatization.
Mild Heat exhaustion Heat exhaustion is the body’s response to an excessive loss of water and salt, usually through excessive sweating.
