HEAT EXHAUSTION AND HEATSTROKE
Heat exhaustion is a milder form of heat-related illness that can develop after several days of
exposure to high temperatures, and inadequate or unbalanced replacement of fluids.
Signs of heat exhaustion include:
• A headache
• Dizziness and confusion
• Loss of appetite and feeling sick
• Excessive sweating and pale, clammy skin
• Cramps in the arms, legs and stomach
• Fast breathing or pulse
• A high temperature of 38C or above
• Being very thirsty
The pulse rate may be slow and weak. If heat exhaustion is untreated, it may progress to heat
stroke. Heat stroke is the most serious heat-related illness.
Look for the following symptoms:
• Feeling unwell after 30 minutes of resting in a cool place and drinking plenty of water
• Not sweating even while feeling too hot
• A high temperature of 40C or above
• Fast breathing or shortness of breath
• Feeling confused
• A fit (seizure)
• Loss of consciousness
