Should I drink energy drinks, soft drinks and coffee instead of water when working in hot conditions?
Coffee and energy drinks cause increased urine output and can make working in the heat more dangerous by causing you to dehydrate more quickly.
You should also not rely solely on soft drinks or caffeinated drinks.
Alcohol should definitely be avoided when working in the heat because it also causes increased urine output – eg if you drink one can of beer, you will lose more than that amount of urine.
The safest thing is to stick to drinking water.
