Last updated 15 July 2022

Someone with heat exhaustion might have been in the sun or heat for a long time. They might look ashen, have a headache or dizziness and feel sick. 

First aid advice

1. Help them to a cool place and get them to rest.

Heat exhaustion happens when someone loses too much fluid and salt usually from sweating in hot conditions. 

2. Give them plenty to drink

Drinking water will replace lost fluids. If you have them, isotonic sports drinks will help replace salts lost through sweating.

3. Seek medical advice

Even if the person appears to recover fully, you should seek medical advice. If their condition gets worse, call 999 for emergency help.

What is the advice for someone who is pregnant during hot weather?

The advice for dealing with hot weather is the same for someone who is pregnant, but it's important to take extra care during times of extreme heat or a heatwave.

The risk of sunburn is great during pregnancy so it's important to wear sunscreen and avoid the sun when possible. Pregnant women are more prone to swelling in their hands and feet due to fluid retention, which gets worse in hot weather.

Pregnant women should make sure they rest in the shade, and if necessary to cool their hands and feet in cool water. The increased demand on the circulatory system, also means it's even more important to maintain good levels of hydration.

However, they may not be able to do these things for themselves so will need extra help from friends, family or neighbours. Remember to look out for others in hot weather and check if they need assistance with anything to help them stay safe.

Back to questions
