1) It's hot for any skin color, compared to most anywhere else in the country. Not everyone enjoys staying indoors for half the year (I have lived in TX.) Folks might move from coastal California and then learn that lesson the hard way.
2) If you are a woman, or woman adjacent, then the fact that religious extremists now set reproductive law might affect the desire to live in the state, if one has a choice.
I personally just drank a lot of water for lunch rides (I'd take a gallon for a ride) and electrolytes. Favorite time to ride, trails were empty.
You are basically agreeing that you are stuck indoors for many months of the year, during day time.
Also, this last year, which was many people's introduction to the heat, it was much worse than just a couple months.
