Dehydration

In case of dehydration, the body needs to ingest more fluid immediately. Occasionally, hospital treatment with a drip is required. The condition is most common among young children, older people or people who have exerted a lot of physical effort when it is extremely hot.

If your body loses more fluid than you take in, you may become dehydrated. If you are dehydrated, you may feel thirsty, have a dry mouth and feel tired. You may also urinate less and your urine will be darker in colour. If you are severely dehydrated, you will have a fast pulse, be confused and may lose consciousness.

The importance of giving fluids immediately

A person who is dehydrated needs to drink immediately. It is best to avoid very sweet drinks and diet drinks, as these can cause diarrhoea, which makes you even more dehydrated.

If you have an upset stomach, it's good to drink little and often, although it can be difficult to drink between bouts of vomiting. You can try water or tea, or a special oral rehydration solution that can be bought from a pharmacy. An oral rehydration solution contains appropriate amounts of salts and sugar.

Helping the most vulnerable

Check if any of your loved ones are affected by the heat. Remember that children may have a harder time recognising thirst. They may need help to stay hydrated throughout the day. It may also be a good idea to ask older relatives and neighbours if they need help.

People who are particularly affected when temperatures rise in the summer are:

  • People older than 65 years
  • People with conditions such as dementia, heart failure, kidney disease or diabetes
  • young children
  • pregnant women
  • people with disabilities
