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.

When your body loses more fluid than you deliver to it, you may experience dehydration. If you are dehydrated, you may feel thirsty, have a dry mouth and become tired. You may also urinate less, and your urine will be a darker colour. With severe dehydration, you will experience a high pulse, confusion and can lose consciousness.

Important to give fluid immediately

A person who is dehydrated must drink something at once. It is best to avoid very sweet drinks and diet drinks, as these can cause diarrhoea, which will make you even more dehydrated.

If you have a stomach upset, it’s good to drink a 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 is available from pharmacies. An oral rehydration solution will contain appropriate amounts of salts and sugar.

Help those particularly vulnerable

Be aware of whether relatives are affected by the fact that it is hot. Bear in mind that children may find it more difficult recognise thirst. They may therefore need help to take on enough fluid during the day. It can also be a good idea to ask older relatives and neighbours if they need help.

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

  • elderly people over the age of 65
  • people who have diseases, such as dementia, heart failure, kidney disease or diabetes
  • small children
  • pregnant women
  • persons with disabilities
