The problem is, if we're going to experience high temperatures more often, we can't just close down society. It's awful working in this environment, but we all need to be there for eachother. I totally get people are being considerate, but staff in hospitals, unventilated warehouses, fireman, retail staff, builders - the list goes on, all have to turn out.
I'm off my food today, but for me I'd prefer something cold out of the fridge that takes five mins. Whatever you decide, enjoy.
