Does anyone knoe how a "wet bulb temperature" is different than the "heat index"?

The terminology seems to have shifted starting just this year, but I don't understand why.

@adam @breadandcircuses

if a person is out in sunlight, wet bulb is a better at measuring the danger a person faces bc it takes in a few more factors, & heat index is calculated in shade.
WBGT <95F is 'unsurvivable'

NWS:
Wet Bulb Globe Temperature (WBGT) is an indicator of heat related stress on the human body at work (or play) in direct sunlight. It [uses] multiple atmospheric variables, including: temperature, (relative) humidity, wind speed, sun angle & cloud cover

@rustoleumlove

Did you mean greater than 95F?

@stillnotahero yes that's why it isays 95F (35C)

"The oft-cited 35C value comes from a 2010 theoretical study. However, research co-authored by Kenney this year found that the real threshold our bodies can tolerate could be far lower. “Our data is actual human subject data and shows that the critical wet-bulb temperature is closer to 31.5C,” he says."
