alt Hacker NewsI've spent a little bit of time in those types of spaces. I absolutely believe the temperatures referenced, but approaching 100 F with humidity above 95% is likely deadly in a short amount of time. And to then seemingly make jokes about selling tickets to walk into an area where you get physically stuck for mysterious reasons adds to my opinion that some of the report seems hyperbolic.
Check out the heat index page I linked above, or this similar one from OSHA: https://www.ohsa.com.au/services/heat-stress-monitoring/.
Yeah it can be deadly but it is unfortunately quite common.
People adapt to it and can tolerate longer spans in it but it's still super taxing and requires regular breaks if you are doing any amount of serious activity. And of course lots of fans and anything else that can raise the evaporation rate and heat dissipation help.
The jokes ngl sound like the exact type of humor you'd expect from people who work out on the floor. Basically "oh well that's fucking horrifying, I bet we could make some money selling tickets".
