Are there any studies that I can read on further about this?

Thanks!

Yes

The temperature should be within a pretty narrow range, and to take it all day you’d want a digital device that continually collects data rather than taking it at different time points. (I’ve also had my fair share of collecting things on a time interval :p) There are definitely factors like movements and heat/cold exposures etc that will make the temperature vary. In the Power of When book, Dr. Breus says if you take a warm shower before bed, blood goes to the periphery so your core temperature drops and it’ll be easier to fall asleep. If you take a cold shower, then all the blood goes to the core and so you are actually warmer. If you really want to know whether your temperature fluctuates per all the hormones that fluctuate, you’d have to be in bedrest not to see the fluctuation from all these factors.

Hello, Daniel. I am not Joe :)

1. A suggestion for checking whether your yellow/amber/orange/red goggles* are blocking blue light: Take a CD out into the sunshine and position it so that you see very clearly the rainbow on the shiny side. Note the blue (and green) area. Put your goggles on and note whether you can detect any blue or not.

* If you are going to bother blocking blue light, might as well get goggles. Glasses are not going to be as effective. You can get goggles with tiny air vents back nearest your ears for comfort.

2. During your morning and mid-day you NEED blue light so you do NOT want to cover screens to block it during that time. Block blue light X hours before bedtime; experiment with timing. One way to make the colored sheet easily removable is to staple the sheet to something (fabric?) about the same size to make a sleeve of the right size for your monitor/screen.

3. F.lux does not block (all) blue light. It is pleasant to use and it changes light properties according to the clock with little (or no?) effect in daytime. If its schedule doesn’t fit your sleep timing, change your location in the program until it works well for you.

While blocking blue light for hours, don’t make the mistake of thinking that just a few seconds of blue light won’t hurt. Those few seconds will reduce the flow/production of melatonin.

The not-for-profit organization Circadian Sleep Disorders Network (CSDN) has a lot of information on its website. Here’s the URL for their infographic; check out the rest of the site as well.

And regarding the red RUBYLITH sheet. Can I put it on a macbook? If yes, what do you do when you actually want to see “normal” colors on the screen in the daytime? Do you keep taking it off and putting it back on?
Is the red RUBYLITH sheet at all necessary if I am using f.lux?

By the way, why do you use f.lux all day? Is there something wrong with blue light during the day?

Thank you for your time

Thanks Joe! :) That was wishful thinking! :D

You bet :)

Cinema isn’t good.

Hope you are doing great! Just a quick (quite stupid) question, but I seriously couldn’t find an answer on the internet, so thought I would ask. I thought you might have an answer. About blue light – does watching a movie in the cinema also exposes you to blue light. It is always said about electronic devices, but I couldn’t find anything about the cinema. If you have any idea, I would appreciate it!

Cheers,

Aleks

edit;
…was was it? (please include units so i can convert in needed and compare with mine).
should of course read
…what was it? (please include units so i can convert in needed and compare with mine).

Thanks for the comment lise,

i’m gonna give it a trial myself…so a few questions if i may;

1. what time do you go to bed…so i can work out how many hours before bed you take your d3. & possibly adjust my timing. tho initially i’ll probably try 3-4 pm anyway.
2. how much d3 are you taking (i currently take 2000 IU daily between 9&10 am).
3. how long did it take before you noticed improvements with your sleep.
4. have you had your d3 level tested, was was it? (please include units so i can convert in needed and compare with mine).

Much Appreciated.
Thanks Again.

Interesting.

My longer comment failed to post, so I’ll leave at that for now.

Great, just had to clarify that. Is it due to the difference between orange vs red in blocking light spectrum?

Different times – red 2 hours b4 bed. Orange after like 5PM.

1) Fine
2) Yes

1. if I wear orange glasses at night (to cover my eyes) but am still exposed to uv and blue lights; is it enough or do I want to find ways to cover the rest of my body as well (basically, im usually in my trouses in front of my pc/tv at night with the red glasses on)?
2. is chewing gum before bad bad for circadian rhythms?
