Vulnerable people and people sleeping on the streets are at greater risk of heat-related illnesses in summer, especially as heatwaves become more frequent and intense.

Find out how to keep yourself and others safe during high temperatures.

Heat-related illness

Sweating is the body's way of regulating its temperature. However, if your temperature gets too high, you cannot cool down properly. This results in heat exhaustion.

If your body cannot cool itself down within 30 minutes, it runs the risk of turning into heatstroke. This can be severe and needs to be treated as soon as possible. Exposure to high temperatures, drinking alcohol and overdressing can all contribute to heatstroke.

Signs of heat exhaustion include:

  • Dizziness and confusion
  • Excessive sweating
  • Fast pulse
  • A temperature of 38 degrees or higher
  • Deteriorating response levels

Help someone who is sleeping rough during a heatwave

If you see someone who may be sleeping rough and vulnerable to heat-related illnesses, there are ways you can help. You could hand out items such as:  

  • Sun cream
  • Frozen water bottles
  • Hats and sunglasses
  • Handheld fans
  • Umbrellas
  • Lightweight t-shirts

These can all offer a welcome break from the heat. In London, the London Cool Spaces app highlights where people can access water and shade.

The NHS has four simple steps you can take if you find someone suffering with heat exhaustion.

  1. Move them to a cool place
  2. Lie them down and slightly raise their feet
  3. Give them plenty of water, sports or rehydration drinks
  4. Cool their skin with a spray or sponge

If they don’t cool down within 30 minutes, call 999. If the person becomes unresponsive, put them into the recovery position.
