It is too hot outside.

Global warming is real and it is killing us, anyone saying something else can go fuck themselves.

Luckily my home has good isolation, currently all windows and the balcony door are open to let in what little cool air is around.
Later I'll close them and keep it that way.

Sure, the heat inside will rise, but slowly over the course of the day.

Better than letting it all in and dying of a heatstroke.
