I don't, not when it's searing, as I simply can't function in it... When it starts to approach 30°C (as it did here yesterday and is due to again today), you'll see me sitting in the shade outside, hopefully where there's still a cool breeze, with an ice-cold drink, or inside with the curtains drawn, in front of an electric cooling fan!!
Thank goodness we have a stone floor in our lounge, as opposed to a thick wall-to-wall carpet, which helps keep the heat down...
Marco.
