I don't remember the exact threshold (It is definitely the case, over 98 degrees Fahrenheit -Body temperature, but that seems high), where moving air no longer cools you. I think that humidity can bring that threshold waaaayyyy down.

I used to live in Maryland. The summers there are brutal. On hot days, rolling down the window is like having a hair dryer pointed at your face.

I was talking with a friend of mine in Delhi, a couple of weeks back, when they were having the heat wave.

It's no joke. People are dropping dead at their workstations.
