Beating the Heat: Recognising and Responding to Heat Related Illnesses

As temperatures rise across the United Kingdom, both outdoor workers and the general public face an increased risk of severe temperature exposure. Understanding the clinical distinction between a mild heat illness and a life threatening emergency is a fundamental first aid skill.
For safety managers and individuals alike, recognising the early warning signs can prevent minor discomfort from escalating into a catastrophic medical event.
Distinguishing Heat Exhaustion from Heatstroke
Heat exhaustion is a systemic reaction to prolonged exposure to high temperatures and inadequate fluid replacement. It is a serious condition but is generally reversible with prompt intervention. The clinical presentation of heat exhaustion includes heavy sweating, profound weakness, dizziness, nausea, and skin that feels cool and clammy to the touch.
"Heat exhaustion acts as the body's final warning system. If the warning signs are ignored and the core temperature continues to rise, the body's cooling mechanisms will fail completely, resulting in heatstroke."
Heatstroke is a severe medical emergency that requires immediate intervention from emergency services. When a casualty develops heatstroke, they stop sweating entirely. Their skin becomes hot and visibly red, and their core body temperature spikes to dangerous levels. The casualty may exhibit profound confusion, slurred speech, and loss of consciousness, and they may experience seizures.
Immediate Action and Clinical Response
The initial response to heat exhaustion focuses on rapid cooling and controlled rehydration. You must move the casualty into a shaded or air conditioned environment immediately. Encourage them to drink cool water or specific oral rehydration solutions slowly. Do not allow them to consume beverages quickly, as this can induce vomiting.
You should actively cool the skin by applying wet towels to the back of the neck, under the arms, and on the forehead.
Clinical Alert: If a casualty demonstrates any signs of confusion, stops sweating, or loses consciousness, you must suspect heatstroke. Call emergency services immediately. While awaiting paramedics, aggressively cool the casualty using cold water or wrapped ice packs applied to major pulse points.
