Drink more water when working in a hot environment.
Everyone needs to drink more water when working in a hot environment – whether it’s indoors or outdoors and regardless of how active we are.
Don’t wait until you’re thirsty – it’s much better to have frequent smaller drinks of cooled water rather than infrequent large drinks. On hot days, you should drink a small cup (200ml) of cool water every 15 to 20 minutes.
Remember - cool water, not extremely cold, because it can cause stomach cramps.
Workers with medical conditions (eg: on limited fluid intake, taking prescribed fluid or salt pills) must check with their doctor before commencing work in extreme heat.
