What a fascinating thread.
The discussion strikes a chord. I've been working in an office environment for the last 3 years and my computer use has gone through the roof. Within months I became long sighted and now use reading glasses. Allegedly my lenses have lost their flexibility, but that quickly?
Summit else that's happened which is very eerie, I wake up anytime between 3am and 5am. Regardless of what happened the night before or what time I hit my scratcher. As a chef, morning for me was anytime after 9:30am. Bizarre.
I also used to do a lot of diving, the colour spectrum is very apparent, blue is the last colour to disappear as you sink before it all becomes monotone, just contrast. Flick a torch on and whoa! It's like Disney land down there.
A colleague at work has recently had a couple of melanomas removed, not unusual in NZ with our lack of ozone and 7 minute burn time during peak summer. Thing is, the melanoma started when she was working in Sweden, Kiruna, above the arctic circle. Due to lack of sunlight many public areas have the equivalent of sun bed lights.. Definitely something to consider with light exposure. Sadly, a very high suicide rate up there, too.
I do have a bit of thought on diet, muddy. Carbs get a bad rap but the big issue is processed carbs, GI, and what you eat with them. Sadly, cake is basically refined and partially refined sugar.
See if you can find a copy of Michael Pollan' book, In Defense of Food. It illuminates the huge gaps in our nutritional knowledge very well and can give you a more considered perspective of how to eat rather than categorise specific nutrients and their alleged effects. It's a good place to start the food journey, any hoo.
Thanks for bringing this up, I'm going to look into some better spectacles for work. And get back into diving.
In "blue" water, with no distance perception, your eyes focus on the inside of the mask lens. A whale could swim past and you would be oblivious. I spearfish and eventually learned how to extend the focus of my eyes manually, a bizarre sensation, you can feel the muscles in your eyes working.... Must get back into it!
On another note.... Told you I was fascinated.
Talking about how the spectrum of sun light changes over the course of a day, how it affects us and how plants use it for photosynthesis. I had a conversation recently with a cop who busted an, ahem, commercial grower. This guy had replicated the full spectrum of light for his grow system. The lighting mimicked a natural day but he controlled how long the day was.
Shirley this idea could be used to improve on artificial lighting in our work spaces and homes?
