How much water should I actually drink per day?

The NHS recommends drinking 6 to 8 cups or glasses of fluid a day. Water, lower-fat milk, and sugar-free drinks including tea and coffee all count. You may need to drink more if you exercise, the weather is hot, or you are pregnant or breastfeeding.

The "8 glasses" rule is a rough guide, not science. A better approach: check your urine colour. If it is pale straw colour, you are hydrated. If it is dark yellow, drink more. Simple as that. Also remember that food (especially fruit and vegetables) contributes about 20% of your daily water intake.
