Recognising heat-related illness
Heat can cause illnesses such as heat cramps and heat exhaustion which can lead to the life-threatening condition, heatstroke. Heatstroke is fatal in up to 80% of cases.
Heat can also worsen the condition of someone who already has a medical issue such as heart disease or diabetes. Most reported illness and death is due to the effect of heat on those who are already ill.
