Warmer temperatures are on the way in the UK as the summer progresses, so it is important to be aware of the signs of heat exhaustion.

Heat exhaustion is simply a condition that occurs when your body overheats and symptoms can start suddenly or progress over time.

In the summer months, this is particularly a risk and it is crucial to try and keep cool on very hot days.

Here are all the signs to look out for as well as recommendations on how to help cool someone down if they are suffering from heat exhaustion.

What are the signs of heat exhaustion?

The signs of heat exhaustion that are listed on the NHS website are:

  • tiredness
  • dizziness
  • headache
  • feeling sick or being sick
  • excessive sweating and skin becoming pale and clammy or getting a heat rash, but a change in skin colour can be harder to see on brown and black skin
  • cramps in the arms, legs and stomach
  • fast breathing or heartbeat
  • a high temperature
  • being very thirsty
  • weakness

They add: "The symptoms of heat exhaustion are often the same in adults and children, although children may become irritable too.

"If someone is showing signs of heat exhaustion they need to be cooled down and given fluids."

How to help cool someone down

The NHS recommends moving someone to a cool place if it looks like they are suffering from heat exhaustion.

Additionally, you should remove all unnecessary clothing like a jacket or socks, and get them to drink some cool water, sports drink or rehydration drink.

Finally, cooling their skin by spraying or sponging them with cool water would help as well as fanning them.

They should start to cool down and feel better within 30 minutes, but if not it is important to call 999.

How to prevent heat exhaustion

To help prevent heat exhaustion or heatstroke the NHS says:

  • drink more cold drinks, especially if you're active or exercising
  • wear light-coloured, loose clothing
  • avoid the sun between 11am and 3pm
  • avoid excess alcohol
  • avoid extreme exercise
  • if you're inside on a very hot day, close curtains, close windows if it's hotter outside than in your home and turn off electrical equipment and lights that get hot

This will also prevent dehydration and help your body keep itself cool.
