If anyone is struggling with sleep, I highly recommend episode 1-3 of the Huberman Lab podcast ( https://www.youtube.com/watch?v=H-XfCl-HpRM ), it has literally changed my life. Dr. Huberman is a Neurobiologist at Stanford and explains the science of sleep vs just telling you to not look at bright screens at night. I struggled with sleeping for 20+ years, now I easily wake up early. The biggest game changer: Sunlight…

Podcast looks good. Thanks for sharing. Heads-up for those who care: It's a commercial podcast with sponsors, trojan ads and all, sadly. https://hubermanlab.libsyn.com/rss

I've found his recommendations/sponsors to be extremely useful. They are curated choices in market areas I am unfamiliar with.

What really worked for me is having a full glass of water on my bed stand. Wake up and drink the entire glass. It really works immediately for me.

Where was this study done? Was it done in a place with mostly sunny days, or mostly cloudy and dark?

In the location where this study was done, what kind of lives to these people lead?

Do people living in more relaxed, sunny, quiet, dark-at-night environments sleep better than people who live in cities with constant street noise, much less direct sunlight, and more light pollution at night?

Earlier quoted context omitted.

Incorrect. The RDA and TUL amounts for vitamin D are wrong. 10k IU/day is safe. Dr. Fauci takes 6k IU/day. My levels of 25(OH)D3 are optimal. It takes slightly over what the real average TUL should be because of my mass and apparently poor absorption. Edit: Cortisol levels are fine. I also had a complete HPA/G/T workup by an endocrinologist. The results were unremarkable. I even had testing for pheochromocytoma, alth…

No, even 5000iu/day is too much for some people, as previously discussed on HN at length. https://news.ycombinator.com/item?id=24261948

And no to that too. RDAs try to be one-size-fits-all guesstimates.

For Vitamin D3 in particular:

"The model developed for UL derivation was summarized in 1998 (IOM, 1998), and it acknowledged that the lack of data would affect the ability to derive precise estimates." [0]

Furthermore, an RDA and a UL doesn't work for D3 because the ranges across people don't harmonize to specific "safe" or "adequate" numbers for a given demographic. 1000 IU is too much for some people. [0]

Blood tests trump RDAs. I need over 10k IU per day, but this could cause hypercalcemia, calcification of tissues, and/or calcium kidney stones in other people.

That's interesting. Is there a paper I can read? Quite interested in this stuff. Cheers

My vitamin D level is only optimal when taking an average of 11000 IU / day (D3 + K2). It hasn't improved my sleep quality. As an example, I woke up at 3:30 am this morning and feel like I haven't slept at all.

Maybe your problem doesn't depend on Vitamin D. Have you tried contacting a doctor?

Yeap. Lots of specialists. Many areas are under investigation.

One is activation of the There is a possibility of an autoimmune disease like lupus or MS causing dysautonomia. I also have inappropriate sinus tachycardia and hypertension without obvious causes. All roads point towards the autonomic nervous system.

Another one of these "eggs are good"/"eggs are bad" flip flops that happens every few years. Before this the "science" was that too much vitamin D disrupts sleep. In fact it seems to have disrupted mine. It's 4AM, and I can't sleep even after taking a MJ brownie. I take 2000IUs daily and my values are "normal" now. And yet I've been suffering from insomnia shortly after I started taking this supplement. Who do I beli…

Or it could be that, as with many things concerning the human body, the reality is more complicated than a simple yes/no question.

I needed better sleeping and tried various things. In the end I stopped drinking coffee and tea. For me its now just hot or cold water, sometimes a herbal tea, and an occasional beer or orange juice. First caffeine-free weekend I had terrible headaches, than came weeks of strong urges (I felt I was an addict). In these weeks I just fell asleep on the couch or even at my desk at work. I slept a lot these weeks, during…

Agreed, went caffeine-free almost 3 years ago and feel so much better. Had initial brain fog, and like you described some pretty debilitating headaches and migraines from the caffeine withdrawal, but it passed after a couple weeks.

If you're interested, I found a not-quite-coffee alternative that seems to satisfy my craving. It's a dandelion root substitute, the brand I drink is Dandy Blend. More like instant coffee than a good ground bean coffee but it does the job.

Sucks for me who lives on a place where the first rays of sunlight come at 7:30ish at this point of the year, and 9:45 a few months later...

>The biggest game changer: Sunlight in your eyes within 30 minutes of waking up. I don't think the sun rises for another hour after I wake up for work.

Buy a wake-up light alarm clock. Costs max. 50€ for a base version. Popular here in the Nordics for obvious reasons.

The suggestion is sunlight without sunglasses after waking up. That is extremely bright light hitting your eyes. Wake-up alarm clocks may be helping you, but not as a substitute for whatever is being suggested here.
