Direct sunlight exposure is around 100,000 LUX, cloudy bright is just several thousand (according to MS Copilot). Not so intense, really.
I have had high troponin levels for 20 years as well as Blood Factor V, maybe greeting the sun every morning has been good for me as well as my dog. A thickened heart wall has left me with two gears out of four, but I am still blessed by God and lucky at this point.
