Use to take ice packs you freeze to then use to keep your lunch cool in whatever you carry lunches in. Also had a couple hard-plastic small rectangular packs that went into mini coolers that could be frozen …anyway, we’d put them under our Nintendo deck back in the day, to keep it cool, because it’d be summer and back then we didn’t have air conditioning, and a lot of games we played didn’t have saves, so we’d keep that Nintendo deck on for hours & hours and it would run hot like that.
Also, this sucked but it works; put on a bathing suit, while in doors, & get a cold shower, and then surround yourself with some electric fans. Then as soon as you start to feel hot again, go get another cold shower. Again, it sucks, having to constantly get wet, but it was some relief.
Honestly I’d live in my bathtub chin deep in cold water if I ever lose the ability to have AC now, I’m too old to deal with the g.d. heat anymore.
