That's interesting! Can you provide some links to evidence regarding Vit K2-MK4, its effects on calcium in the bloodstream, and how that inhibits the effects of catecholamines and leads to sleep induction?

Vit K2-MK4 Osteoblasts better than Vit K1 in my experience, ie 50mg of K1 is nowhere near as good as 5mg K2-MK4. Calcium amplifies the effects of the catecholamines which probably explains why tea drinkers prefer hard water. Military also give out tea, during and after a exercise. High Vit A and Vit D can also lead to hypercalcemia which makes you feel good. https://scholar.google.com/ Remember Thomas Pynchon and be…

I was hoping you could provide the specific studies and research you are using to make your claims. Linking to Google Scholar is not sufficient.

This is why OLED lights is the future: http://www.ioledlight.com/ and https://www.oledworks.com/

Doesn't OLED tech (in TVs, screens) also works by having a blue emitter with filters for white/ colors (which is what the article covers) ?

I can relate deeply to this. Spent the last 2 years trying to get treatment for what turned out to be a neurological sleep movement disorder with an insomnia component. Basically I have sometimes ~150 involuntary limb movements/hr during sleep, they sometimes wake me up but even if they don't I wake up exhausted. Things are getting better with medication finally, but yeah I've learned not to bring my sleep issues up…

How did you get that diagnosed?

had a polysomnograph (aka sleep study) done which allowed them to recognize that I was having these movements during my sleep. My wife had always assumed I was just tossing and turning constantly while awake and I obviously had no clue what was going on without that PSG

This sounds naive perhaps but would velcro straps or other gentle arm restraints prevent movement and allow you to sleep better?

The first issue with that is periodic limb movements (or PLMs) by definition can actually range from subtle movements almost like muscle spasms to large limb movements, so constraints would be limited in efficacy for that purpose specifically. This would also surely negatively affect any insomnia, sucks enough waking up at 2am involuntary when I'm not in restraints

That said, my father has a sleep movement disorder as well- but his is more extreme and called REM Behavior Disorder. Basically means he physically acts out his nightmares on a regular basis. His neurologist has been trying to convince him to put barriers on the side of his bed so he doesn't fall out and injure himself but he's been hesitant. sucks getting older.

IKEA sell a Tradfri bulb (304.413.80 in Europe) which has a 2200K colour temperature and 250 lumens output, which I've been using as a bedside lamp for the past year. At the brightest setting it is more than enough to read a book (usually we use it at around 50%), and it dims enough that we use it as a night light for kids. The new EU light labelling requires a spectrum to be posted online. This bulb still has a blue…

That bulb has a poor CRI though. Probably not very important for reading I guess.

What are you trying to achieve? Because I could also add, your omega 3 intake can also be a factor, Omega 3 reduces the number of osteoclasts for the flip side of the bone health and also increase the size of neutrophils which will engulf bacteria which invariable destroy bones and leads to arthritis and rheumatoid arthritis. Growth hormone, either 95% of tryptophan via the kynurenic pathway or nicotinic acid on an empty stomach will increase the number of neutrophils, although medical experts will normally give intravenous growth factor aka growth hormone. Stress hormones like adrenaline will reduce the effectiveness of neutrophils (Left shift iirc) as will a B12 deficiency (neutrophil hyper segmentation). Omega 3 will increase the neutrophil size by just under 40% so that they are large enough to consume yeast cells, which makes me wonder if brewers yeast is potentially harmful. Manganese Ascorbate is also useful because much of the vit C is stored inside the neutrophils, so larger neutrophils mean high levels of Vit C, and the manganese can contribute to MnSOD to neutralise ROS inside the mitochondria and help to repair cartilage in places like knee joints.

Omega 3 also help the serotonin and melatonin in the brain and spinal fluid which also helps with getting to sleep.

When the UK govt were giving cod liver oil and malt to kids in the 50's or 60's, under the pretence of preventing Ricketts, they knew what they were doing to control future GDP and aggression levels.

Considering the Japs are experts in Vit K studies, and prescribe K2-MK4 to post menopausal women who are naturally consuming an iodine and omega 3 rich diet seafood diet and also happen to have some of the longest living females in the world, and some of the highest IQ's in the world, I think looking to them will give you more info than a typical western diet.

Just 150micrograms of T3 (Triiodothyronine - one iodine atom removed by selenium, with 80% of this T4-T3 conversion taking place outside of the thyroid gland) will half the time spent in Intensive care in hospitals. Tyrosine is the main ingredient of T3 (hormone) & T4 )pro-hormone) so your metadata for getting more tyrosine in your diet is when you start to get grey hairs.

Many govts, like the UK Govt are deliberately harming the population with their treatments provided by the health care system and what is taught at med school, which clogs up beds and pushes up house prices with the elderly who dont want to go into nursing homes. A crude example of Maslow's Hierarchy of Needs, an agenda many govt's are now following around the world.

And choline can also reduce stress levels by reducing the CO2 build up in the body and lungs. Choline is used in the alveoli of the lungs to facilitate the gas exchange, its also used in the cell walls and the connection between neurons. The more choline you consume, the better your physical performance and mental ability. Personally I found L-Alpha glycerylphosphorylcholine to be best, but yet to try citicoline which is used in hospitals for brain injuries and costs about £3k a kilo.

Like I said, what you are trying to achieve?

Been a while since I used a MacBook but can't you do Shift+Opt (or just Opt?) Brightness+/- for an incremental change still? Works with volume too.

I love apple devices, but man, these undocumented things make me question whose team their UI people are on. It doesn't feel like they're on my team.

I used to feel this way, but since learning that much of the advanced functionality is unlocked by Opt/Shift/Ctrl or some combo of them + click, I find myself digging that consistency more and more. At this point if I don’t see the option I need, I know 9/10 it’ll show up when I opt+click.

Right but this is a false dichotomy, LEDs are both inherently bad AND put to uses that enhances their detrimental characteristics.

Uh, just no. LED lighting have modes of working that can be bad. You just need to be way more picky and knowledgable with LED lights which is hard for most customers, vs "just buy an incandesent bulb"

Nice "well actually" there. So is the proposal consumers perform their own spectrographic tests before making a purchase or can we just go with "leds are bad" given the overwhelming majority of the products available on the market demonstrate harmful characteristics with no clear way of discerning which are the outliers at time of purchase?

Those “color vision correcting” glasses (e.g. EnChroma) use an optical technology called notch filtering: “EnChroma glasses are spectral notch filters that remove light from two regions of the visible spectrum: from the region near 480 to 490 nm (in the blue–green part of the spectrum) and from the region near 580 to 590 nm (in the orange–yellow part of the spectrum).” https://www.practiceupdate.com/content/the-effec…

I did some digging and notch/bandpass filters are on the expensive side, but you can buy sheets of lowpass filters for a reasonable price: https://www.ocushield.com/products/anti-blue-light-filter-la... I would just form a cylindrical lampshade out of such a sheet and call it a day. My bedroom has a dimmable, multi-colored LED in a cloth lampshade that definitely filters some blue light and it's possible to sleep wit…

Yeah, it looks like off-the-shelf spectral notch filters are aimed at laser laboratories. Around 800 usd per lens so 1600 for my glasses, bit steep. You’d get some pretty awesome looking Doc Ock style goggles out of it, though
