Heatstroke is caused by a failure of the thermostat in the brain, which regulates the body temperature. If someone has a high fever or has been exposed to heat for a long time, then their body can become dangerously overheated. Heatstroke can develop with very little warning, causing unresponsiveness within minutes of someone feeling unwell. Your priority is to cool them down as quickly as possible and get them to a hospital.
Other symptoms of heatstroke are:
- Headache, dizziness, and discomfort
- Restlessness and confusion
- Hot flushed and dry skin
- A fast deterioration in the level of response
- A full bounding pulse
What should you do if you think someone has heat stroke?
- Quickly move them to a cool place and remove their outer clothing but ensure you maintain their dignity.
- Then call for an ambulance.
- Wrap them in a cold wet sheet and keep pouring cold water over it until their temperature falls to at least 38°C.
- Once their temperature seems to have gone back to normal, replace the wet sheet with a dry sheet.
