A wet bulb temperature of 88F or above means sweating no longer works. It's not a sustainable living condition, and without external ways to cool off, it will eventually lead to heat stroke and death in even healthy people. It's slow cooking for the human body, if you will.

Here's some of tomorrow's forecast.

Dear JJ, you obviously haven't lived in the southeast US for a while? Have you? Or on earth for that matter. SMH

Seems like you don't know the difference between wet bulb and surface temperature. Thanks for your concern, though.

Hi JJ, yes Sir. I most certainly do. Trained weather observer for over 4 decades. How about You Bro? I don't post a resume everywhere.
Good 🌄 morning. Enjoy your heat training. 🔥

So Mr. Trained Weather Observer, are you going to provide anything insightful, or just low tier snark?

Certainly could. What would you like to add. Where should we begin to educate this topic? 🤔 Desert survival takes about three weeks to teach correctly if I remember correctly. Hydration is the #1 issue obviously.
46 chromosome mammals require clothing, and shelter. That is usually where I begin. Physiology of the human body. ♥
I pass you back the talking stick.

So, what's your issue with my parent post that made you come at me? Is it wrong?
