Travel days, flights and the arrival reset

Living here means flying. Long-haul, layovers, the red-eye home — and at the other end, often, a wall of heat at arrivals. A travel day quietly dries you out, and the fix is simpler than the wellness internet makes it sound.

Why flying dries you out.

Aircraft cabin air is very dry, and over a long flight it steadily pulls moisture from you. Add the coffee, the wine and a routine that has gone sideways, and you tend to land having drunk far less water than a normal day.

The arrival into heat.

Step off into a 40°C summer and the climate stacks its own demand on top of the flight. Pushing through it is the usual move. Rehydrating properly on arrival is the better one.

A travel routine that works.

Sachets travel light, so a couple in your bag is easy. Fill a bottle once you are through security, take one before or during the flight and one on arrival, and sip rather than chug. Plain water for the short hops; an electrolyte sachet for the long, drying ones.

General guidance, not medical advice — if you are managing a health condition or a long-haul with specific needs, check with your doctor.

Why electrolytes, not just water, on a big travel day.

A long travel day into the heat is hours of fluid loss — dry cabin air on the way, sweat once you land. Water replaces the volume; an electrolyte sachet puts back the minerals you lose in the warm part. For a short hop in mild weather, water alone is plenty.
