Why do I need to drink fluid?
- To replace the fluid you lose every day from sweating, breathing and going to the toilet.
- To prevent constipation and to help your kidneys work well.
- To prevent dehydration (your body getting too dry).
How much fluid should I drink?
- Don’t wait until you are thirsty - drink often throughout the day.
- Try to drink at least eight glasses a day.
- Drink more if you are being active or if it is a hot day.
- Drink more if you have been vomiting, have diarrhoea, or have a fever.
What fluid is best?
- Water is best as it is healthy, cheap and easy to get.
- Other fluids include milk, tea, coffee, juice, soup, custard and jelly.
- Flavour a jug of water with lemon juice or slices of fruit and keep it in the fridge.
- Take a bottle of water with you when you go out.
- Have a jug of water and a glass on the table at meal times.
- Homemade icy poles/popsicles are a great way to get more fluids in during hot weather. Try using a mix of fruit juice and water.
- Not drinking enough can make a weak bladder problem worse. Talk to your GP or continence nurse if you are worried.
