Pillar 03 — Hydration
The simplest lever. The most overlooked.
Hydration is the one variable almost everyone underdoes — and one of the cheapest, fastest ways to feel better. Water quality, electrolytes, and the daily habits that keep your cells working.
In this section
Three things to understand.
Most “drink more water” advice stops where the interesting questions start.
01
💧
Daily Hydration Targets
How much water you actually need — by body weight, activity level, and climate. Why “eight glasses a day” is a starting point, not a rule.
02
⚡
Electrolytes & Minerals
Sodium, potassium, magnesium — why drinking water alone isn’t enough, when supplementation matters, and what the sports-drink industry doesn’t want you to know.
03
Dehydration
Dehydration starts long before you feel thirsty. Knowing how to recognise it early — and what to do when it’s serious — is one of the most practical pieces of health knowledge you’ll ever pick up.
📱
Scan your beverages
The SmartBar app scores beverages the same way it scores food. Use it on every drink you buy and watch how quickly your hydration improves.
