In my opinion……It’s the only way to get the benefits of full spectrum sunlight.
An orange tree won’t produce fruit with a tarp over it. Circadian rhythm (body’s block clock), melatonin production, D3, etc. can’t be optimized with clothes and sunscreen let alone your eyes/retinal pathway blocked from the benefits of full spectrum light by glasses.
Sunglasses/sunscreen…they are all shitcoins pushed by centralized medicine and big pharma.
Live with nature the way your ancestors did for thousands of years and your body will thank you in return.
