Or you can just get a sweatter and let the house get cold. So long as the pipes don't freeze, a furnace can easily be run less without a substantial reduction in comfort. On the other hand when it's hot, there is only so nude you can get.
Unfortunately our secret weapon for handling heat has a weakness: humidity.
Sweating just not good enough for me, even when it's dry. I can cope with it, it's not like being hot would kill me (within reason and if I stay hydrated), but it has a serious impact on my performance. When it's hot my brain gets foggy and my thoughts slow. Maybe I could still operate at a caveman level of performance in that sort of weather, but I couldn't do my job.
