Water is involved in almost everything your body does. It carries nutrients, controls body temperature, cushions joints and helps remove waste. Even mild dehydration can leave you feeling tired, unfocused and irritable.
Here is how hydration supports your health and simple ways to drink enough every day.
Your brain needs water
Being well hydrated helps you think clearly and stay focused. Headaches, low concentration and a foggy feeling can all be early signs that you need to drink more.
Energy and performance
Water helps your muscles and heart work efficiently. When you are dehydrated, everyday activities and exercise can feel harder than they should.
Digestion, kidneys and skin
Good hydration supports healthy digestion, helps your kidneys filter waste and keeps your skin feeling comfortable and supple.
How much should you drink?
Needs vary with your size, activity level, the weather and your health. A practical guide is to drink regularly through the day and check that your urine is pale yellow. Drink more when it is hot or when you exercise.
Water-rich foods count too
Fruit and vegetables such as watermelon, oranges, cucumber and lettuce add to your daily fluid intake while providing valuable vitamins and fibre.
If you have heart or kidney conditions, your clinician may give you specific advice about fluids, so always follow their guidance.
Pay attention to early signs of thirst, such as a dry mouth, tiredness or darker urine, and treat them as a gentle reminder to reach for a drink.
