The NHS has issued an urgent heatwave alert, advising the public to “call 999 now” if they observe severe skin symptoms indicative of heatstroke. As temperatures rise across the UK this weekend, recognizing early warning signs of heat-related illness is essential for health and safety.
Heat exhaustion, a common condition during extreme heat, can worsen into heatstroke if not promptly addressed. The NHS notes, “Heat exhaustion does not usually require emergency medical help if you can cool down within 30 minutes.” However, should heat exhaustion escalate into heatstroke, it demands immediate emergency treatment.
A primary symptom to monitor is skin that feels hot to the touch but does not sweat and may look red. The NHS emphasizes that this sign can be harder to detect on brown or black skin, so heightened vigilance is necessary. Immediate medical assistance via 999 should be sought if heatstroke symptoms are present.

If a person remains unwell after 30 minutes of resting in a cool environment with adequate cooling measures and hydration, emergency services should also be contacted. Other critical heatstroke symptoms calling for urgent help include confusion, seizures, loss of consciousness, or difficulty breathing.
While awaiting medical help, the NHS advises placing an unconscious individual in the recovery position to maintain airway safety.
Before heatstroke develops, recognizing the symptoms of heat exhaustion is key. These include heavy sweating, weakness, dizziness, nausea, headache, muscle cramps, and irritability—especially in children.
If heat exhaustion symptoms appear, immediate action can prevent progression: cool the person down, provide fluids, and move them to a cooler place. Follow these four vital steps to aid recovery:
- Move to a shaded or air-conditioned area
- Remove excess clothing
- Apply cool, damp cloths or spray with water
- Encourage slow sipping of water or oral rehydration fluids
Stay with the person until they have fully recovered, which should take around 30 minutes. If symptoms persist or worsen, call 999 without delay.
The NHS highlights that heat exhaustion and heatstroke risks increase sharply during hot weather or physical exertion. To reduce the likelihood of heat-related illness, individuals should:
- Avoid strenuous activity during peak heat
- Drink plenty of fluids regularly
- Wear loose, light clothing
- Seek shade and stay indoors during high temperatures
Following these precautions will help prevent dehydration and enable the body to regulate its temperature effectively, safeguarding health throughout the heatwave.
