Heat exhaustion does not usually need emergency medical help if you can cool down within 30 minutes. If it turns into heatstroke, it needs to be treated as an emergency. You or someone else have signs of heatstroke, including: still unwell after 30 minutes of resting in a cool place, being cooled and drinking fluids. They should start to cool down and feel better within 30 minutes. Call 999 now if: You or someone else have signs of heatstroke, including: still unwell after 30 minutes of resting in a cool place, being cooled and drinking fluids.

Heat stroke happens when excess heat overwhelms your body’s built-in system for cooling itself.
Excess heat can come from outside your body, this is environmental heat.
Excess heat can also come from inside your body, this is heat your metabolism generates during physical activity.
Normally, your body can get rid of excess heat — primarily through sweating — and restore a normal body temperature.
But if the air around you is very hot or your metabolism generates lots of heat, your body may struggle to keep up.
Babies and children also face an increased risk of heat stroke, they’re vulnerable to extreme heat, even for short periods of time.
Because heat stroke can lead to life-threatening complications, every minute counts when it comes to getting medical care.
