Sounds good about the fridge heat. Hydration is probably the single most important thing whenever your in the heat.

But I never could bring myself to just drink water until I started using a small plastic bottle of water. Maybe it's the fear of dust! but I like to drink water out of a bottle - even if I fill it up from the sink. I hate drinking water from a glass (unless it has ice). I'm actually more likely to drink more water from a bottle.
I have one next to my bed at night. But I drink more water now than I ever did.

I buy those 'pop-ice' sticks by the case for the kids. (only $3.99/100 case!) They eat them all day long and I know I'm keeping them well hydrated.

If the elderly could be encouraged by friends and family to eat more icecream and drink more fluids - that might help lower the incidence of heat stroke.
