I'm trying to upload a book that's not on here but apparently I have to provide an isbn or Asin number but the books I'm trying to upload is from the 1950s and has neither 🫪

Can anybody help?

Europe is currently in a heatwave, and I am suffering. I‘m on medication that makes me a lot more sensitive to heat already, but we also don‘t have AC and my room has three outer walls, meaning I am being baked alive.

So far I got through it by just chilling, eating ice cream, and reading a lot (goals) but yesterday I had a lot to do running across town, got no rest, and got myself a giant headache because of heat exhaustion, and my eyes are incredidibly dry because I slept in front of a fan (?), so no more reading😤

So I have two questions:

1. Does anyone who is more used to heat have any advice for cooling down and keeping the body functioning? Neither me nor the infrastructure is prepared for heat, and it is awful☹️
2. Any recommendations for easy, not complicated but interesting audiobooks (or podcasts (this is how you know i‘m desperate)) for me to follow as I wallow?
