Sandfoot said..I'm trying to find ways of keeping cool, sure drinking heaps of water and wearing light clothing, we have small fridges at the plant to put drinks etc, the missus said tennis players have special neck scarves they wear in the heat to cool em down, don't know how a neck scarf will go down at the plant but if it keeps you cool might be worth it.
Cooling around the neck is a biggy for me, I personally just used to leave a wet hand towel in the freezer overnight, chuck it in a mini esky with some ice packs and wrap that around my neck and wipe my forehead when I played tennis in crazy heat. Once that's done you've still got the ice packs to hold on your face and wherever else. You get proper ones that will probably be less mess etc
Places to cool with ice are your wrists, neck, forehead, inner elbows - wherever the blood flow is close to the skin.
Another that might be a good idea for work is a damp bandana, 1 in the fridge and 1 on your head and switch as the one you're using warms up
