The biggest issue in the US is wet-bulb temps in the southeast.

For people that aren't aware, wetbulb temps essentially measure how well you can cool yourself down by sweating. Humid air means sweating is less effective since it can't evaporate.

A wetbulb temp of 95°F (35°C) will kill someone in less than a workday if they're not given proper breaks.

A wet bulb temp of 35°C will kill a healthy person sitting still in front of a fan.

Yeah, any wetbulb above 30°C (86 °F) is potentially fatal without lots of rest breaks and water and shade and such. 35°C is unsurvivable - and not something that happens naturally on Earth.

Yet.
