My European girlfriend always complains about how badly she sleeps when she’s back home in the summer. Just like Americans, Europeans don’t like hot houses. But it’s the way things are there, so they try to cope.
“The natural fibers in my blankets keep me cool”
”I open my windows at night”
“I take a cold bath or shower when I need to cool off”
”Air conditioning is too expensive”
The irony is that all of their alternatives still accept the premise that it’s uncomfortable without AC on a warm day. They just use different workarounds because that is their culture.
I personally prefer to set a number in my thermostat and always be the perfect temperature. I work outside every day in the summer, so I would rather not deal with being uncomfortable during my personal time. And if I were competing in the biggest competition of my life, I would also prefer to be comfortable.
