Soo. many. questions >. <
I'll try to break it down into one long one and three short ones.
1) Wasn't it discovered that it's not necessarily light that triggers that response in our bodies when it comes to sleep and the release of melatonin? A lot of studies suggest this and they measure the effects of sleep and different influences in people who are already conditioned in this way, aligned with the structure and routine of our society. Obviously throwing off somebody's sleep cycle, which happens to align with sunrise or sunset more or less, reeks havoc. There was a study that isolated people from light and time for an extended period of time and they found that people's internal clocks were conditioned closer to 25 hour cycles rather than 24, where every day the people would go to sleep an hour later. Along the line of the same question, weren't circadian rhythms found to just be tuned to a response of something daily that's consistent? Well, what's more powerful and consistent than the effects of daylight/sunrise and darkness/sunset? However, this can be artificially created through other sensory means. Am I getting this wrong?
2) I didn't actually quite get the connection between blue light stimulating our wakefulness and how that's what causes us to sleep in long burst rather than 4 hours at a time. The question here I guess is therefore implied.
3) Also, was it 4 hours sleep, 2 hours awake, and then 4 hours sleep again (then 14 hours awake of course, or something of this sort?
4) Aren't our natural sleep cycles around 1. 5 hours at a time, so it would be closer to 4. 5 hours and perhaps 3 the second time around?
Thanks! A response would really be appreciated, especially if the answers to these are actually well understood at this point. That would be incredible knowledge to attain! :D

Science, poesy and video have never met so well to my knowledge since Karl Sagan. This particular episode almost brought a tear to my eyes because I feel much affected by this phenomenon, causing social jetlags.
I think that spending enough time before a screen should lower the thresholds of receptors, meaning that if we bathe enough in light, we might still be able to follow a biological circadian rythm, providing some accomodations. I prefer, though, the choice of lowering lights wavelengths, for light pollution to science and nature.

Living in a rather dark 1st floor I once did buy a very specific light bulb that made light like in a Greece summer at the nsea at 12 o'clock. This was great. I awaked. However, I had to replace it some weeks later because I did not get tired and did go to bed later and later. It was good and bad.

Although this video has a point it almost implies that light from the fire or candle is good for us when such light is bad for you too in a different way, the light is dim and so you can strain your eyes if your not careful and certain types of candles and fires can give off gases.

LED technology has made huge advances in the last couple of years and incandescents are currently primed for extinction. If anything I hope the lighting designers get the colors right and employ the newer advances in controls to better sync with our bio-circadian rhythms.

To the narrator and the scriptwriter:
Wow! Wow! The last minute of the video, even all of it, just made me realize the impact and art of bringing the words together as a tool to captivate one's heart and mind. :)
I almost fell in love with the narrator. haha

As someone who sleeps for three hours, wakes for an hour, then sleeps for another four or five hours, then wakes again for an hour to sleep for another one or two -- all interrupted by machines and devices -- this is extremely interesting.

I liked the video automatically because, I already know I'm going to like all of ya'lls videos. After I finished watching the video, I'd forgotten I'd already liked it and wanted to like it again. If only I could: )

I'm really enjoying these. The narrator was a good choice. I try not to care about the voice of the narrator but there are some I just can't help but dislike. This narrator has a GREAT voice for narration.

If this is the natural way to sleep until electricity then the undeveloped world without electricity would be sleeping this way. Are they? I don't think so. Is there some reason for that?

Very interesting, it's somewhat scary to think about the lights we see can make a difference in our lives.
It always blows me away how humans have evolved into what we are today.

HA! I read about this somewhere before but when I told people and couldn't find the thing I read again no-one believed me, now I'll just show them this! Thanks Deep look, Great video

I do exactly that, sleeping a few hours, waking up, read a book or watch a video then go back to sleep.
This is our natural rhythm? Maybe my brain knows that.

It's sad that we don't function like this anymore. I'd like to wake up in the middle of the night, do something relaxing for a while and then go back to sleep.

So, I mean, is there anything we can/should do about it? Or do we have no choice but to deal with the ramifications of living in an artificially lit world?

But if phones were invented back then, I'd wake up and start watching you tube and quickly fall back asleep when I hear footsteps outside my door.

Now I'm wondering if I'd sleep better if I put red tissue paper over the lights in my apartment. Eh, guess it's at least worth a try.

I have that 3rd period in my days.
Granted I stay awake between 4 and 13 hours and sleep between 10 and 12 hours, but that's life yo!

I wish our society would make lights that helped us get back into this sleep rhythm I think we will be much more healthy this way.

I recently installed f. lux on my PC. I read about it in an article by a recently retired hockey player who needed to get sleep.

Is that why people wake up in the middle of the night sometimes then go back to sleep? Or is that a different thing?

I was surprised to see that you made a video about night light because I thought it as mostly animals you guys liked.

This was so interesting! I never would have thought modern lighting is disrupting our sleep patterns.
