Hydration Habit Score
There is no such thing as a "hydration age". This page does not estimate one. It compares your drinking habits and simple signs, such as urine colour, with NHS guidance of about 6 to 8 cups or glasses of fluid a day.
Before you start
Method : Hydration Habit Score — a custom points score written by this site. Each answer adds or subtracts the points shown in the Methodology table below.
Validation : Unvalidated. The points have never been tested against any laboratory measurement or health outcome, and the result is not an age.
Review : not reviewed by a qualified clinician. Educational only — not a diagnosis or a medical test.
Confusion, fainting, not passing urine for 8 hours or more, or a fast heartbeat with dehydration needs urgent medical help (NHS).
Your answers stay in this browser tab; nothing is sent or stored.
NHS guide: 6 to 8 cups or glasses a day, more in heat or exercise.

Methodology & assumptions
Your score is the sum of the points below. The weights are our own judgement. The old version added made-up years for skin elasticity, lip dryness, electrolytes and climate and gave a "hydration age". Those aren't reliable measures of hydration, so they were removed with the age output.
| Factor | Answer | Points |
|---|---|---|
| Fluid on a typical day (water, milk, tea, coffee) | More than 8 glasses | 0 |
| 6–8 glasses | 0 | |
| 3–5 glasses | +1 | |
| Fewer than 3 | +2 | |
| Usual urine colour | Pale yellow | 0 |
| Dark yellow | +2 | |
| Feeling thirsty or dry-mouthed | Rarely | 0 |
| Sometimes | +1 | |
| Often | +2 | |
| Heat or heavy sweating without drinking more | No | 0 |
| Often | +1 | |
| Sugary drinks | Rarely | 0 |
| Daily | +1 |
Worked examples
Fewer than 3 glasses, dark urine, often thirsty, heat without extra drinks, daily sugary drinks: 2 + 2 + 2 + 1 + 1 = +8 points.
6–8 glasses, pale urine, rarely thirsty, drinks more in heat, rarely sugary drinks: 0 points.
Understanding your result
This counts habits and signs you reported. It is not a hydration measurement and not an age. Fluid needs vary with body size, heat, exercise and health conditions. Health-agency guidance linked below is general and based on populations, not on this score.
