Extreme heat and dry conditions can cause you to dehydrate and your body to overheat.
It’s important to eat a balanced diet to help your body replace any salt you lose by sweating. Aim to drink 6 – 8 glasses of liquid a day, and more if it’s hot.
You may also need to be careful if you’re taking some types of medication that affect water retention. Speak to your GP if you’re concerned.
Watch out for certain signs – particularly for muscle cramps in your arms, legs or stomach, mild confusion, weakness or sleep problems. If you have any of these, rest in a cool place and drink plenty of fluids. Seek medical advice if your symptoms persist or worsen.
