Just so everyone knows what HOT is --
(Indeed, no one comes to Texas for its lovely Summers...)
I'll tell you something I've been doing, and I've leaned into after learning about it.
I get sun mostly in the early mornings, here in Georgia it doesn't reach over 80 until 9-10am.
The rest of the day I'm either in my home or at my job, until 3-6pm I'm outside in the evening sun.
I keep the temperature in my home cold. I take long cold showers. Turns out, the mitochondria produces internal melanin essentially tanning our insides after prolonged cold exposure. Keeping us healthy while not receiving UV. This is clever design by God to make sure people living in northern regions stay healthy while not receiving any sun at all.
For me the sun is obviously outside and plentiful but out of my personal choice I'm choosing to live this way during the peak UV hours. I have nothing against the sun and would be out there more if not for constant air traffic, living 2 minutes from a military base, and my neighbors' constant construction.
As much as I like the sun I find it undesirable in my current circuмstance.
Whether or not you sunbathe a lot it's beneficial to keep your indoors as cool as possible or take ice cold showers if need be, this would be the healthiest because you're rehydrating your skin.
