I am extremely curious if scientists have considered sending someone with an intrinsic circadian rhythm disorder, especially Irregular Sleep-Wake Rhythm Disorder or Non-24-hr Sleep-Wake Disorder, often for whom your PRECIOUS day-night cycle means NOTHING. Ahem. Anyway you end up with people who, if allowed to do so, sleep when they need to regardless of daylight. It's extremely crippling here on earth where you're expected to have a fairly exacting daytime schedule, but possibly perfect for a profession where the name of the game is "sleep well and sleep when you can."
People actually interested in neurology leaving comments: Wow I had no idea that going to space cause such issues. Great video! Everyone else:S A N S. U N D E R T A L E
It kind of amazes me how Undertale has made such a huge impact on the internet community that now almost everyone associates the word "sans" with the funny skeleton dude in the blue jacket instead of the font "comic sans" or the literal French word "sans" meaning "without"
You can tell Hank's really excited about the just the thought of us becoming an interplanetary species, and fair enough! When you remember that we're animals born from the natural process of evolution like very other species, it's pretty mind blowing that nature made one that can actually leave the playing field itself and migrate between entire planets.
Dude, this is SO why aliens have big heads, to protect their brains. I'm not sending any of my grand-nieces and nephews into space until the force shield is created.
It seems like a really bad compounding problem, astronauts arrive on Mars sleep deprived, neurologically compromised, irradiated and confused. The perfect recipe for disaster when its -200 in the shade and hard vacuum outside.
5:47 not sure how accurate that is though. I worked for half a year in night shift and had after a few weeks no problems sleeping by daylight. Same for me colleges, many of them worked for decades only night shifts and they got quite used to it.
this video made me want to go to space way less than i did before. having csf pooling in my cerebellum and making my eyes bulge is the one that i'm feeling particularly strong second hand discomfort over.
Sounds VERY similar to IIH! Idiopathic intracranial hypertension (IIH) happens when high pressure around the brain causes symptoms like vision changes and headaches. “Idiopathic” means the cause isn’t known, “intracranial” means in the skull, and “hypertension” means high pressure. IIH happens when too much cerebrospinal fluid (CSF) - the fluid around the brain and spinal cord - builds up in your skull. This puts extra pressure on your brain and on the nerve in the back of your eye, called the optic nerve.
An LED system that simulates the light at different times of day would be pretty nice to have at home, too. Especially for people who work at home and spend a lot of time in one room.
Once we get there we are going to know how exotic pets feel in a house. There are people who say "how do they survive in the wild if they need so much care?" Send those guys to mars so that they understand
I’ve always wondered if the blue light phenomenon on the human circadian rhythm affects colourblind people as well? Does your eye still detect blue light even if it can’t translate it into the colour blue for your brain, or are those two processes of detection and translation basically the same thing?
It seems like it might be easier to create a large permanent space station near Earth and figure out all these issues using it before we even think about colonizing other planets. (I also just want an actual spaceport to exist.)
People manage to live in the"Land(s) of the Midnight Sun", though it's not for everyone.Does the effect in space have to do with the change of orbit itself ? ( Fluids & such ).
Oooooh. So blue light isn't really _really_ harmful, it simply can mess with your circadian rhythm if you expose yourself to it in the evening. Interesting.
Shielding with high hydrogen content, like water for example? I wonder if storing the water for the mission in tanks around the living quarters would provide any decent shielding. You have to carry it all the way there any way, so it wouldn't be adding that much "extra" weight.
Do you think astronauts with delayed sleep phase disorder would have similar problems with sleeping? Or would they have other issues that would throw them off?
I feel like the shielding problem might be best solved by assembling long-distance spacecraft in orbit or on the moon, so you can get away with having quite heavy vehicles. Assuming, of course, that the magnetic field idea is impractical.
Is the heart the only pump in the body. You take about how fresh fluids is brought into the brain, so are their smaller pumps though out the boys or dose the heart handle all fluids?
@IdkGoodName Vilius Venus has enough atmosphere to protect against solar radiation. It's the acid rain that might be a problem. Ages ago I watched or read something on the dark clouds on Venus. The speculation was that the dark clouds had something to do with life. A TH-cam video on killer Venusian space mold would be cool! Maybe it was an Anton Petrov vid.
I feel like if we used the magnetic field around the ship like how earth has it would act as an emp to the ship and cause unlimited technical issues on the flight but that's for sure the best way to shield
emps are just sudden and extreme changes in a magnetic field causing electrical currents in any conductors. this can be shielded against and any system used to protect a interplanetary ship would produce a static field and wouldn't cause any serious problems.
@@Babarudra Only partly, and only for parts of the year. But on the South Pole there is no difference between "day" and "night" and that conditions lasts for the whole year.
@@bjornmu that's not true. It's the same as the Arctic. Part of the year it's 24 hours of day, part is 24 hours of night, and the rest is transition between the 2.
@@Babarudra On the literal actual South Pole (not the rest of Antarctica) there are no days or nights. In between the summer and winter there's just a single really slow sunset where the sun spins around the horizon as it goes down. The same is true for the North Pole but there aren't research stations at the North Pole because it's not on land
@@oliverwilson11 - There IS 24 hours of dark and light at each pole. I don't know why you think there isn't. But having been stationed at MSAQ (McMurdo), I know first hand what I'm talking about.
So what I am hearing is that I’d be perfect for deep space flight, considering I have absolutely no Circadian rhythm whatsoever. Light has precisely zero effect on whether my body thinks it’s time to be awake or asleep. Growing up, Non-24 (as it is now called) made going to school absolute hell. But now as an adult, it has its benefits.

There is nothing Comical about SANS
Except it can leave you looking like him if it's severe enough
A short enough trip can leave you looking a little funny and make it hard to stand up, so I guess that could be Comic SANS?
@peter *_TIMES NEW ROMAN_*
the joke was sans humor.
Except it's not pronounced the same way... nice try though.
The SANS effect, huh?
So what you're saying is if we go to Mars, we're gonna have a bad time?
what can i say except bruh
This was so deeply clever.
You feel your cerebrospinal fluid crawling down your back
It will take alot of determination
It won't be that bad. We'll just be super BONE-ly.
I could not take this seriously after you said that they named a symptom SANS
Hey, at least they didn't call it "Cosmic Sans"

What did the astronaut's brain say while en route to Mars?
"I thought I was ready, but now I've lost my nerve."
I saw the first four words, I recognised the style of comment, I saw the picture, I saw your name.
I still wasn't ready.
Solitude on Mars is what I've been training for my entire life.
All I need is life support.
I call it "Mom."
"[Astronauts] sleep six hours on average."
Me too, you ain't special.

What will happen to the CSF if the “self-corrected” brain comes back to earth?
Dealing with the problems of SANS fills the scientists with determination.
It seems like a really bad compounding problem, astronauts arrive on Mars sleep deprived, neurologically compromised, irradiated and confused. The perfect recipe for disaster when its -200 in the shade and hard vacuum outside.
LazyLife IFreak I read hard vacuum as ‘hard to vacuum’ but either way it’s not great
Hilariously explains why tons of sci fi horror movies have antagonists who go crazy.
Thanks for this video, this is one side of space travel I hadn't seen covered, especially not SANS . I never even thought about sleep issues either.

I remember hearing about a study that found circadian rythm to deviate only an hour at most in total isolation from sunlight.
An LED system that simulates the light at different times of day would be pretty nice to have at home, too. Especially for people who work at home and spend a lot of time in one room.
Is it just me? Sunsets make me super sleepy but when its night time i feel awake
Same
Stop looking at your screen, and you will sleep easier

You have to be kidding me, now I can't even go to space to get a 26 hour rythm, because of freaking larks? I need to find Lamuella...
Oh, you’ve got SANS? *Looks like you’re gonna have a bad time.*

My brain doesn't want to be on this planet anymore, so, in that sense, yes, it's ready for Mars.
"is your brain ready for Mars?"

Oooooh. So blue light isn't really _really_ harmful, it simply can mess with your circadian rhythm if you expose yourself to it in the evening.
Interesting.
spaceX, you better be taking notes on this, cause you really need to get starship prepared with vital essentials

Yep ready for mars
My brain isn't even ready for mondays, so...
If I had activities to keep me mentally busy time would fly by for me.
"ok Dan we are at Mars."
Me: Huh?? Already?
Do you think astronauts with delayed sleep phase disorder would have similar problems with sleeping? Or would they have other issues that would throw them off?
I volunteer to be the guinea pig for all the necessary test if they are done in the microgravity of space
I'm so excited to witness how we build and manage extraterrestrial colonies.

Or just use Justin Beaver no radiation would want to touch him.
My brain was not even ready for earth.
Better question: Is Mars ready for your brain? Let's disassemble the planet and turn it into a Matrioshka brain host
November Pin is ready for Pre-Order FYI.
3:12
Let's see whether the development of plaque-degrading enzymes will help.
Aubrey DeGrey's SENS Research Foundation for example is exploring this.
yep, the futile search continues for a practical use for space travel.
SANS, messing with us using gravity... of course
It's awesome how fast the human body can adapt. Oh there is no gravity? These bones don't need this calcium then.

Also the radiation has a solution - polyethylene is an excellent radiation shield. The ship walls will be coated with it.

during the mars flight the ship will rotate around its central axis at 7.7rpm, creating mars-like 'gravity'. So no problem.
How will they pass through the impenetrable firmament?
