When I lived in Seattle, my solution was a 2’ square fluorescent panel I got from a gardening supply place called “The Indoor Sun Shop”. I grew up in the South and got real bad seasonal depression up there; it probably saved my life. I paid all of $300 for it. Plus like twenty bucks for a mechanical timer, because I discovered that there were a lot of mornings where I was too depressed and mopey to turn it on myself.…

there was a post a day or two ago about vitamin D3, as well as academic literature finally catching up to medical science vis a vis vitamin D3. I won't cite, but only because i don't have a way to index my personal PDF repository, but the common consensus among people who study such things is that anyone living above the 20th parallel (or below, technically) absolutely must supplement vitamin D3, as even a full day i…

If you are going to supplement D3 over 5000iu, I would recommend getting a 25(OH)D blood test once or twice a year, ideally 2-3 months after each change in dose. Then compare your levels to the levels here and adjust dosage accordingly: https://ods.od.nih.gov/factsheets/vitamind-healthprofessiona...

It may also be worth adjusting dosage between winter and summer months, depending on the amount of outdoor activity you do.

No one in the parent posts has said anything about "literally zero people". The OP made a claim ("invented in 2017"), and this very claim is being criticized. I found perplexing that you interpret the very same words in almost opposite ways.

I cant find it again but I read an article about how brightness goes up with technology and human spend roughly the same proportion of income on light. Kind of disproving the led efficiency is good for the environment argument. Not revolutionary, better to break that pattern.

You contradict yourself.

If humans spend same proportion of income on lumens, and you get more lumens per watt, then you will use less wattage per the same proportion of income. Ergo LEDs are more efficient.

Surely you don't mean the 20th parallel, right? That would include most of the population of the world wouldn't it?

Bright lights give me a headache, especially in midday when it's bright outside. I'll often resort to wearing sunglasses indoors when it gets out of hand.

Perhaps it's a certain kind of light, but I don't get the same kind of headache outside in bright lights. (Although I do find bright days painful.)

yes, 20th does include most of the world population. Humans started out within 20 degrees of the equator for the vast majority of human history, and eventually fanned out, but it takes longer than a couple thousand years to make up for the loss in D3 synthesis.

edit: it could be 25th or 30th, i have a hard time finding a single paper amongst thousands, either way it includes 90% of the population of the US, regardless of what parallel.

How about bitcoin? It's not so much an idea as a piece of software, but being predicted on wasting energy it's going to do a lot of harm. That's an example of this class of game-theory based ideas. I believe that there are other ideas like that, things that set up spirals that are a lot worse than just "destroy energy to make money". Obviously they're not going to be universally compelling, an idea that's dangerous l…

It's not a waste if the product the PoW generates is valued as equal to or greater than the cost of generating the PoW, and the market ensures that is the case, as miners cannot operating at a loss. Where it can be socially harmful is when…

Money laundering is useful but that doesn't mean it's good. A Ponzi scheme can generate wealth but it can't generate value. Wealth without value is maybe not wasteful, but it is harmful.

> Where it can be socially harmful is when energy consumers don't pay for the cost of the negative externalities that the energy they purchase created in its generation, but that applies to all energy usage, not just that used in generating PoW.

Bitcoin alone uses as much power as a medium-sized nation. The increased power usage has caused old fossil-fuel power plants to come back online.

All I've heard is the danger of calcium precipitating out of your blood and causing arterial blockages. Apparently D3 potentiates this so that the concentration of blood-borne calcium doesn't need to be as high for this to begin. I've always been wary of going up to max-dose levels for that reason.

with the way research is going i'd expect to find it's something else in conjunction with D3 that causes that, and not merely D3. like D3 and a high sodium diet, or D3 and .

as mentioned though, i only think that 500-1000iu is not enough for most people. I'm not a doctor though, but it is one avenue of alleviating SAD as well as lethargy and stuff that most people vape/smoke/caffeinate to deal with.

DIY Perks [1] has a good tutorial on how to make a super bright LED panel from LED strips. Quite easily, actually. Been using one of those in my office for the last eight years or so. I use a server PSU for power. I was surprised to see how bright it is when I once went outside while it was on. Not only was my window the brightest in the entire street by far. But it actually illuminated the trees around my window. If…

One doesn't need to make lights out of led strips, shop lights have transitioned to LED. $20 each, https://www.harborfreight.com/5000-lumen-4-ft-led-hanging-sh... 5k lumens, 60w I also came to post the DIY perks video about simulated sunlight, the effect of parallel rays really changes the geometric mood of the room.

It really does help.

Just don't keep working into the night under them, because whoa boy - talk about sleep disruption. Those nice bright lights make it surprisingly easy to work until 6am and not even realize it.

You should take D3 with vitamin K2 (talk with your doctor first if you're on blood-thinning medications) to avoid calcium being dumped into soft tissues (K2 ensures it preferentially goes into bones).

It's a good idea to get your vitamin D status tested yearly and aim to be at least 50 ng/ml (120 nmol/l), but not more than 80 ng/ml (200 nmol/l).

As an example for dosages: I take about 7000 IU of vitamin D3 and 180 mcg of vitamin K2 daily. My levels test at about 180 nmol/l and my blood calcium is normal.
