About the Daily Water Intake
Staying hydrated helps energy, joints and concentration. A simple guide is about 30–35 ml of fluid per kilogram of body weight.
Sip through the day rather than all at once, and remember tea, coffee and food all add to your total.
Frequently asked questions
Do tea and coffee count?
Yes — they still hydrate you. Water is just the simplest, no-calorie option.
Can I drink too much?
For most people it’s hard to, but if you have heart or kidney conditions, follow your doctor’s advice on fluids.
