@TwoCables This reply is being written long after your thread was posted, but contains an important health-check heads up for you.

I'm glad you had improvement of the symptoms you described, including frequent heavy night-time urination. But did you know that frequent heavy night-time urination is also a very common symptom of the serious disease diabetes?

Untreated diabetes can cause major problems, including organ failure, if left untreated over a period of years. Diagnosis is simple, you just tell your doctor about your symptoms and say you'd like to be checked for diabetes. You will receive a referral for a urine and blood test.

Whether or not the preservative TBHQ was in fact a contributor to your problems, we don't know. Single subject 'experiments' like yours do nothing to eliminate the placebo effect, and merely skipping your high non-complex-carbohydrate snack before bed may have alone helped lower your blood sugar levels (cf diabetes again!), thereby increasing your chance of better sleep, irrelevant of TBHQ content.

And even should TBHQ be a (resolved) issue, it doesn't mean you don't have diabetes as well.

I looked at the so called "factsheet" about sleep disturbance & insomnia webpage you linked, and see that it's scientific basic is very, very dubious. It quotes apparently reputable sources, but only a handful of them, and only few pages of each at most, certainly not enough to prove that most of the voluminous list of food additives listed on the webpage affect sleep in any way. The anecdotal evidence listed (none of that is even for TBHQ) is not scientific and proves nothing. The word 'fed' in the website address gives the misleading impression that it's some sort of government website. It isn't.

So please get a medical check-up promptly, if you haven't already (from a GP, since they are all trained in scientific medicine, not some self-appointed New Age 'expert). Be sure to tell the doctor about the frequent heavy night-time urination, whether or not it still occurs.

My Windows Insider Build is actually 19645.1

IDK why the driver info shows it like that...

Look,I started up my computer and its warm again! s i g h

It doesn't really matter to me as long as my mattress is comfortable, I sleep just fine.

Agree with you

It seems a bit abstract to me. Probably need to learn more

@fivosrazor1 Thanks for sharing this information. Why the temperature of LED is increased?

@clubare said in i have a problem:

Really strange question.

No it's not. All you said is you don't know how to use certain effects. What the hell do you mean by that?

Good lord, dude. Do you want help or not? I can help you, but you have to meet me halfway here. Don't be so damn vague by only saying you don't know how to use certain effects. Explain what you want to know! Sheesh.

I can't read your mind you know. All I know so far is that you are saying you don't know how to use certain effects. So, what do you mean by that? What do you want to know? Why are you asking? Help me help you.

A lot of people think that sleep and circadian rhythms are nearly the same thing, but this isn't really true. But there are a lot of other circadian systems in the body, and they can become compromised if you spend all your time as if it's the longest day of the year - e.g., melatonin duration in the blood will expand to use 12 hours during the winter (even if you're not sleeping that long), and melatonin is also pretty good at fighting cancer.

There aren't so many places on the planet where people have 16 hours of bright sunlight, and there are none of them that do this year-round.

We think most people are "darkness deprived" - so a healthy pattern of light includes seeing some lower light levels, even when it's not right before bedtime. We also think that lowering the light several hours before bedtime can help people align with their day, but individuals vary a lot in this.

Overall this is an area we are putting a lot of work into right now - both in showing that this idea is the right thing to do, and in making it more flexible.

The main reports are ICNIRP and IEC62471 - they define a blue light hazard spectrum. The landmark papers include Ham 1976. Before that we didn't know that "blue light" would be the most sensitive part of the spectrum for a retina.

Ratnayake did not measure irradiance--that is, they measured total power from a laser, but then the press compared the power in this tiny laser dot as if it had been spread out over a square centimeter. This is just not the same thing! A tiny dot at this power level damages retinal tissue and when it's spread out so it's 10,000x dimmer, it does not.

This looks like a good summary:

@fluxzeta said in How to get to 800K on a mac?:

I have seen posts saying that it is possible to get under 1200K, the lowest setting on the f.lux sliding bar, by pressing alt+shift+page up/page down. However, Macs do not have the page up/page down key, and when I tried using the alternative on a mac for that key (fn+up arrow/down arrow), that did not seem to work. Does anyone know how to get down to 800K on a mac?
It would probably be correct to assume that the Macintosh SE is not of the FDHD kind, since your question merely refers to 800K floppies.

Unfortunately, it is absolutely necessary to create 800K floppy disks on another older Macintosh computer with a (built-in) floppy drive for 800K (and 1.44 MB) disks. This means a pre-1998 computer.
good luck

They are talking about color temperature. 800 Kelvin.

@herf That's quite interesting, I figured it would be more linear. That's really nice to know looking at a 5500 lux sky during the day whether cloudy or blue will be more than enough to shift my schedule.

One more question, do our eyes need to be open to have a light response (I currently think it doesn't matter)? So if I stare at the sky with my eyes closed, will the schedule shift be the same as with them open?

I think this is an obvious one as if you could close your eyes to block out bright light responses then that would be more discussed.

Last question for this topic (so far anyway); What would be the most accessible (easy to purchase either in store or online) most stimulating indoor light that your aware of? Any style, any base etc, as I would like to replace two lights in a ceiling fan if they'll fit (max size is about a 26w cfl, but the socket will handle two 72w halogens).

I really appreciate all this information as I was thinking I needed over 50,000 lux during noon to really get my schedule in check. It's really nice to know that 1,000 lux early in the morning is plenty. On that note, maybe it's not all about schedule shifting. What about the part where not seeing enough bright light during the day affects how sensitive we will be to light after sundown--is 1-10 thousand lux still enough to mitigate those effects?

Have you tried the blue light blocking light bulbs from Harth? www.harthyourhome.com

Today I am sticking to doing light activities that mostly involve laying down and resting. I made sure to get nutrients and protein in my body to help give me energy to get through the rest of the day without having to nap too often. I am spending time today reading, writing, and taking care of myself..
maybe i will see a doctor
