I'm sitting here, in front of my computer,
... wearing a house dress (well, just a loose cotton dress I bought online that is too loosely cut in front so I can't really wear it outside of the house), fan on full bore blowing on me, not oscillating, a bottle of ice in front of it in the hopes that that will cool the air just a little more, another fan on full bore in the next room, this one oscillating and blowing by me every now and then, with a chamois draped around my neck for more cooling, and another towel to daintily dab the sweat from my face, and a water bottle, empty, because I tend to drink all 500ml at once.
And like that, I can concentrate on work.
Yeah, it's hot, but there are some hidden advantages to going no air con! I am COOLER a lot of the time, except for that one time of the day when I feel like I'm going to melt. But most days around that time, I'm at work (air conditioned), and if not, I take a shower, or go shopping (air conditioned) and every evening I have to take the kids to various classes in the car (air conditioned) so I do get to escape it usually, though I end up having to fight with my students over what temperature to set the air conditioner at!
I'm cooler at night, sleeping. I remember when we used to have the air con on to sleep (switching off later) I would always feel hot in the morning. Now I get to enjoy, really enjoy, the cool breezes of morning, and those moments when I actually get to feel COLD and - gasp - have to put my blanket on (my cotton air cell blanket).
But the best thing is not instantly wilting and breaking into a drenching sweat the minute I leave my house - or just the living room. Which means I can get more done around the house but best of all, spending time outdoors is much more pleasant. All I need is shade and a mild breeze and I feel fine. Night events are even better, no sweat (literally) in the cool evening.
