Hydration basics
Why staying hydrated matters for an active life, and simple, sensible habits to drink enough through the day.
Overview
Staying reasonably hydrated helps you feel and perform better day to day, and it matters more when you are active and losing fluid through sweat. The good news is that for most people it is straightforward: drink regularly across the day, have water easily to hand, and drink a little more around exercise and in hot weather. You do not need to overthink it or track every millilitre.
Thirst is a useful guide for most people, and pale-coloured urine is a rough sign of being well hydrated. Needs vary with body size, activity, heat and individual factors, so treat any general advice as a starting point rather than a rule. This page is educational; for specific medical or hydration needs, or if a condition or medication affects your fluids, ask a qualified professional.

How much water should I drink?
It varies from person to person with body size, activity and climate, so there is no single number that fits everyone.
