>how most people aren’t getting enough
What are you basing this on? What counts as 'enough'? And how are you tracking light exposure?

So we built a free app that uses your Apple Watch or iPhone to automatically track your light exposure throughout the day.
It tells you if you’re getting enough, shows you how consistent you are, and rewards habits that support hormone balance.
It's in beta on TestFlight, let me know what you think!

Moreover, sun exposure is not by definition 'healthy'. Spending two hours in the sun at noon in the middle of summer does more harm than good.

Not surprised there because people who spend more time outdoors will typically be participating in physical activity at the same time, while people who avoid sun exposure will typically be seated while participating in sedentary activities.
If we want to see if sun exposure is the sole reason for longevity, we will have to force the subjects to sit on a couch outside.
Claiming that not getting sunlight is the same as smoking is pure garbage.
So you're throwing out a whole study because it didn't cover a specific confounding variable you thought of, than stating a claim with no evidence backing it up?
That's pure garbage.
They specifically call this out in the abstract.
