Growing up in Northern Sweden, I spend most of my summers inside, and having a hard time sleeping.
I've just realized living in Arizona is leading to the same pattern.
The reasons are different though.
Sweden was the mosquitoes, and the sun bouncing on the horizon around 1am, and shining really brightly through my 2nd story window at 3am! Never actually getting dark.
Arizona is because it's extremely hot. 🥵
