Hydration is boring advice that works

Nobody shares a hydration routine. It is the least interesting advice in wellness and one of the few pieces with genuinely solid evidence behind it. Boring is not the same as wrong.

The symptom you blame on everything else

Mild dehydration reads as fatigue, headache, poor concentration and irritability. All four get attributed to work, sleep or mood. Most people are carrying a mild deficit most of the afternoon and calling it a personality.

Why thirst is a bad signal

Thirst triggers at roughly one to two percent body water loss, by which point the cognitive effects have already started. If you are drinking when thirsty you are running behind by design.

Timing beats volume

Chugging a litre at nine does not carry you to six. The body clears surplus quickly. Small amounts across the day hold a steadier line than the same total taken in two goes.

Electrolytes, briefly

Water alone is fine for most people most of the time. If you sweat heavily or drink a lot of water in a short window, sodium helps the body hold it. A pinch of salt in a glass is enough. The sports drinks are mostly sugar.

A realistic routine

A full glass on waking. One with each meal. One before each coffee. A bottle within reach at the desk. That is roughly two litres without ever thinking about hydration as a project.

Set it up so the default is drinking. Then forget about it, which is exactly what good habits are supposed to let you do.
