Back to routine: getting your hydration back on track after the holidays
by AUA Hydrate
After the holidays, the body has to reset on several fronts at once: sport starts again, the office calls, days get shorter — and often, summer's last real heat is still hanging around. That combination is exactly why the return so often comes with fatigue, soreness that lingers, and headaches that feel out of place.
🎒 The essentials
- After a break, the body has lost part of its adaptation to effort — including how it manages sweating.
- Restarting sport in the last of the summer heat stacks two sources of electrolyte loss at once.
- The change in routine (office, commute, new hours) also changes when and how you think about hydration.
Why the return to routine throws off your hydration
On holiday, hydration often follows a spontaneous rhythm: you drink when thirsty, you're outdoors, you sweat differently. The return to routine breaks that rhythm all at once — a new schedule, sport picking back up, days spent indoors followed by an evening workout.
The result: you forget to drink during office hours, then arrive at your session already running a small deficit. That's exactly the combination behind the fatigue and cramps many people wrongly blame on the "return" itself.
Getting back into sport without starting from zero
After several weeks off, or training irregularly, the body has lost part of its adaptation: it sweats differently, regulates temperature less efficiently, and its need for sodium and magnesium stays high even while training intensity itself only ramps up slowly.
The before/during/after protocol detailed in Electrolytes and sport applies especially well to the first weeks back, when the body is working harder than it looks.
Signs to watch for as you get back into it
- Soreness that lasts more than 3-4 days, beyond normal muscular adaptation.
- Fatigue that doesn't lift despite a decent night's sleep — often a sign of a deficit building up over the day.
- Cramps at the end of a session, even one shorter than what you did before the holidays.
- A late-afternoon headache, classic when your daily rhythm changes faster than your drinking habits.
A simple routine for getting back into it
- A stick on waking. Before your coffee, one stick of AUA Hydrate in 500 ml sets the base for the day ahead.
- A fixed reminder at the office. The new schedule is exactly the moment to anchor a new habit — for instance, systematically in the early afternoon.
- Before training, not just after. Getting back into it often means setting off 30 minutes before the session rather than making up for it once you're home.
- No added sugar. Also fine for everyday use, unlike sweeter drinks better kept for intense effort.
💡 The AUA tip: use the change in routine to anchor a fixed moment in your day rather than relying on thirst — the full calendar of good moments is in When to take electrolytes.
