Can't make vitamin D after September in the UK - sunlight passes through too much ozone due to the angle of the sun. There are other good reasons to stop messing with the clocks. E.g. reduction in stress from body clock changes and fewer road accidents in winter. www.ncbi.nlm.nih.gov/pmc/articles...

Therefore increasing the path length by which solar UVB has to travel through the ozone layer will result in a decrease in the number of UVB photons that reach the earth's surface (Fig. 22).40 This is the explanation for why during the winter when living above and below approximately 33Ā° latitude very little if any vitamin D3 can be produced in the skin from sun exposure. People who live farther North and South often cannot make any vitamin D3 in their skin for up to 6 mo of the year.41 For example in Boston at 42Ā° North essentially no vitamin D3 can be produced in the skin from November through February.

I prefer to think of it as receiving the wonderful, warming gift of photons! Here's a nice description too:

"you can think of photons as the fuzzy quantum objects they are, in which any given photonā€™s absorption and reemission through an atomic excitation is not guaranteed to occur over a certain fixed amount of time; rather, it takes place across a smeared-out, probabilistic range of temporal values."

Consciousness is not a passive sponge. We create experience. There are no red photons.

Yup. With CPUs consuming <20W to do useful work, shooting photons into your eyeballs becomes a non-negligible power draw

drskyskull.bsky.social are you aware of the study suggesting photons can experience negative time and if so, what the fuck?
