1. Electrolytes belong in the break, not just water
People who sweat lose minerals. A bouillon upgrade, salted snacks or a simple broth in the staff canteen cost nothing and prevent collapse. Salt is not a luxury. It is prevention.
2. Never run on empty
This is always true in service: in heat it becomes critical. The more movement, the hotter the body. People on reserve don't function anymore: they only survive. Plan breaks before someone breaks.
3. Cool the extremities
Wrists, neck, temples. Cold water on the forearms works faster than cooling a whole room to 20 degrees. A damp cloth helps: but it warms up in 10 minutes and leaves uniforms wet.
4. Eat light
Heavy staff meals at 35 degrees are not a benefit: they are a burden. Water rich fruit and vegetables, less meat, no heavy dishes at midday. The body repays it with performance.
Operators who make sure their team gets through the next weeks notice afterwards how much trust it builds. Heat related absences serve neither you nor your team.
