Water supports temperature control, digestion, joints and more. But there is no single amount that suits everyone.
What affects your needs
Climate, physical activity, body size, pregnancy, breastfeeding and some health conditions all change how much fluid you need. Food contributes too, especially fruits and vegetables.
A practical guide
Official guidance, such as the NHS’s, often suggests around six to eight glasses of fluid a day for many adults, including water, milk, tea and coffee. Pale yellow urine is a handy sign you are well hydrated, while dark urine may suggest you need more.
Easy habits
- Keep a refillable bottle nearby.
- Drink a glass with each meal.
- Drink more in hot weather and when exercising.
Good to know: Some medical conditions, such as kidney or heart disease, require fluid limits. Follow your doctor’s advice.
