But percentages in the stock market seem to be more important to efficiently combat climate change.

With a dry air you can support more than 70º (eg in a Sauna), but with high air humidity, which evite the evaporation cooling by your sweat

You got that flipped.

With dry air, your sweat can evaporate. Evaporation consumes energy, and thus has a cooling effect, making high temperatures more bearable/survivable at low humidity.

With humid air (eg in a sauna) your sweat cannot evaporate because the air is already saturated. This deprives you of the cooling effect, making humid conditions feel much hotter; and making it lethal much faster and at lower temps.

I see the confusion. A sauna is not necessarily humid, traditional Finnish sauna are hot but not high humidity. You're thinking of a steam sauna which is high humidity but lower temperature.

Oh, fair enough. I had no clue that there was even such a thing as a steamless sauna.

Yep.

100f+ degree weather with zero humidity? Sweat evaporates so quickly that with a fan on you or a breeze you can actually feel briefly chilled at times.
