Maybe your Vitamin D3 levels aren’t meant to stay sky high all year
Maybe, just maybe, life is built on seasonal duality, not perpetual summer
Even at the equator, there’s no such thing as true perpetual summer, it’s just a different kind of rhythm. The sun might rise and set at nearly the same time year-round, but rainfall patterns, food availability, humidity, and cloud cover create their own seasonal cues that living systems have adapted to
Equatorial populations still experience cycles, they’re just less about temperature and more about rain, light diffusion, and ecological shifts. The body still syncs to these environmental rhythms
So the idea of keeping D3 status or any biological marker “locked in” year-round is ahistorical and biologically tone deaf
Even nature’s most stable environments pulse
Modern thinking treats health like a thermostat. Pick an “optimal” number and lock it in
What they fail to understand is that biology is rhythmic. Vitamin D3 levels naturally rise with abundant UV-B in summer and decline through winter, mirroring changes in light, temperature, food availability, and circadian gene expression, so forth
Forcing levels to remain elevated year-round through supplements or artificial UV ignores this deeper rhythm and turns you into a neurotic pain in the ass
Winter is a different operating mode
Just like trees shed their leaves, your physiology shifts gears.. altering hormone cascades, immune tone, and metabolic priorities. Flattening these seasonal waves may feel optimized on paper, but it often clashes with how humans actually evolved to function
The point? Health isn’t about constant abundance, it’s about respecting the ebb and flow
