I'm glad that 100 F summers for most of my life were normal and not the result of a heat wave, or I would probably be skating with a cane about now.

It's kinda useless to raise this point unless we can think of some action to do about it.

Should people avoid the sun? Probably not. Sunlight is proven to have a lot benefit in regulating mood and biological clock.

Should people wear sunscream. Maybe yes, maybe no. I'm not sure. I myself prefer sunlight touch my skin. So unless the UV rate is too high, I won't put on sunscreen.

What are the actions that normal everyday ppl can take in your opinion?

stay hydrated with water and electolytes

take breaks in the shade when exerting oneself outside

wear wide brimmed hats

dress in layers, with light colored clothing
