Hydration for heat work

Start before you're thirsty

In heat, thirst lags behind loss. The pattern that works on real sites: drink on a schedule — a cup or so every 15–20 minutes during heavy work in high heat, up to about a litre an hour — rather than waiting for a break and drinking a lot at once.

When electrolytes join in

Guidance from occupational health bodies is consistent on the trigger: for jobs lasting more than about two hours, or with prolonged heavy sweating, water alone should be supplemented with electrolytes. That's the shift our Crew pack was dosed for: 650mg of sodium a serving, sugar-free.

Why sugar-free matters at work

A sugary sports drink every hour adds up to hundreds of extra calories and a sugar crash by mid-afternoon — and for workers managing blood sugar, it's a real problem, not a preference. Sugar-free, properly dosed, is the right default for a crew.

Set the station up to be used

Shade, a cooler people pass on the way to the work — not away from it — cups or bottles that are actually clean, and freezer pops for the hottest part of the day. Hydration programmes fail on logistics far more often than on formulation. Our For Work page covers how we supply crews.
