Buy some decent, quiet, pc fans and sew a wrap-around sheet, with holes at the foot end just for the small fans to nestle into. The idea is you lay on the bottom part, the top part is over you with whatever other light blankets, and the fans are by your feet, ideally one for each side with an on/off switch. They blow cool air into the sheets and help evaporate moisture. It’s the same idea as a lot of very expensive machines.
Build a small frame to securely hold the fans, ensure no obstructions, and hold the end of the airflow sheet, put the power supply somewhere far away, and you’ve basically built a $400+ cooling bed.
I feel like the solution to this is more Luigi, tbh.
People would be less selfish if they didn’t feel so hopeless.
