The most important question: Is blood bending easier with the full moon?

Remember. Before electric light, the easiest way to get around at night was to wait until the full moon. Hence why certain cultures plant/harvest based on lunar cycle. It's much more pleasant to do field work on a cool, moonlit, night vs on a hot summer afternoon. So we have developed a propensity to be more active during full moons.

"Took five minutes longer to fall asleep, and slept for twenty fewer minutes" Insomniacs weep into their pillows....

"[The moon] is a cosmic flashlight" might be the second best simile for a celestial body lol, #1 of course is "The Sun is a deadly lazer"

A dung beetle walked into a bar, and said,"Excuse me is this stool taken?".

Myths about the moon? They're all sheer lunacy!

Hank's definition of moonlight: "A cosmic flashlight shining in your window". Another classic.

When I’m ovulating AND it’s the full moon I’m at my most powerful

When I'm menstruating, I like to use the expression, "I'm turning into a werewolf." Since seems to happen during the full moon more often than not. Even if the moon doesn't actually influence my body in that way, it usually is a good indicator of when I need to buy "werewolf protection".

The whole 'epilepsy and moon' thing also appears in the ancient Mesopotamian material, in which the moon-god Nannar-Su'en is considered to be the ruler over epilepsy. When he's in his full light, the epilepsy-demon is not around as much. Pretty cool that that seems to be confirmed by modern science! 😎 Ancient people weren't as stupid as many think

I love how the topics just get more and more random as time goes by.

My first girlfriend turned into the moon...

What about when the moon hits your eye like a big pizza pie?

See 30% less REM sleep will defiantly make me act crazier so...

Me: Oh, finally a video debunking all myths like the moon's influence on surgeries. Hank: Lemme tell you about dung beetles!

The scorpion's ability to glow, sense their own glow, and hide when glowing brightly, may aid in avoiding nocturnal predators that can see UV light - snakes, desert iguanas, tarantulas, rodents, bats, other scorpions...

Yeah its definetly the moon and not me watching SciShow at night that makes me lose sleep.

Any video narrated by Hank is guaranteed to be a good video.

Regarding point one, I just recently wondered about full-moon related insomnia as my kid woke up at 2AM wanting to play. I have I hypothesis - maybe full moon reflects not only visible light but also shorter wavelenghts such as UV? Maybe the excess of UV radiation during the night (most of our UV comes from the sun, so our bodies read UV - day, no UV - night) somehow messes up the synthesis of melatonin or just breaks our circadian rythm? That is actually a quite an interesting topic :)

In my Nursing career I saw more patients pass away on full moon nights than any other moon formations. Anytime we had someone transfered to palliative care we always asked "is it a full moon", it was not being insensitive, it was to schedule a nurse to sit with the patient on Palliative care 24-7. It was not a wanted situation. But a known statistical occurance.

Please make one of these for "mercury is in retrograde"

When we have phones lights indoors and on the streets, its unreasonable to expect that moonlight would still be effective at synchronizing menstruation. If there is a correlation between periods and the full moon, you aren't going to see it by app statistics, you have to study a population that has little to no artificial light, especially at night where the only sources of blue light are the moon and artificial light.

Omg😱😱😱 you the guy I watched for 4 years to get my degree from college online!!!!! It was you!!!! Thanks luv your Biology 🧬 videos SAVED ME!!!!!! I PASSED MANY TESTS!!!!! ❤️❤️❤️ I’ll never forget your voice!!!!

The many myths about the moon kinda shows how much we either love or hate our moon. I personally love it.

00:25 I just imagined every ER /ED Doctor and Nurse facepalm....

Truth: Sailor Scouts fight evil by moonlight.

I've worked in a hospital and a homeless shelter. It's definitely more anecdotal than actual evidence, but we always had busier or crazier shifts during full moons.

So the full moon WONT turn me into a giant monkey? #feelsbadman

My Dad used to say, "that guy is so mean, he'd give a tumblebug a marble and send him the wrong way home." A tumblebug was a dung beetle or scarab.

I always think this is an interesting topic to bring up. I know a good number of people who have no belief in unexplained events from things like the moon causing issues all the way to paranormal events. Yet many of them who are in medicine/ems say that while no one can explain it, the oddest and most bizarre shifts they work are on full moons. Most went into their fields initially feeling ‘full moon’ as a cause was myth. Yet they came to find that they do see a correlation. But it always stands out to me when very practical, science-minded professionals admit there’s something that happens during full moons!

I loved this episode - I've always been fascinated by the effects the Moon has on life : ) That study of menstrual cycles from info on Clue has me a little worried though. I actually stopped using Clue because I read they sell your data, so I'm wondering how much consent was involved with the people's whose menstrual data was used?

I know that there have been numerous studies on this that 'confirmed' that this is a myth...but as someone who's worked with the public for over 30 years... The studies are wrong!🤣🤣🤣

I have heard multiple times from people who work in maternity wards that there is an increase in labour and delivery during the full moon.

I was expecting to hear about the infinite tsukoyomi.

Regarding the scorpions - How are we defining, “Wandering a round aimlessly?” Were the scorpions hunting, drinking water, developing close sexual relationships rather than chasing their tails?

I’m a police officer in England, I know it makes no sense but we have many more fights, domestics and mental health issues on night shifts with a full moon.

The moon doesn't make people act crazier.....SciShow has never worked in the healthcare field during a full moon.

We get bloodbending during the full moon what you mean??

It makes sense the Moon would have the same affect on the atmosphere as it has on the oceans. After all, air is a fluid too.

My mum works nights as a nurse in a nursing home. She has told me for years that the residents are more "difficult" when there is a full moon. She put this down to the old myth of the full moon causing madness, but after watching this video I suspect it is just because the residents are not sleeping as well as they do at other times.

Fascinating and informative video! Love having myths dispelled!

The hypothesis about epileptic seizures being more common when it's dark outside should be easy to test by looking at seizure rates in the wintertime versus the summertime in parts of the world close to the polar circle. In Scandinavia for instance, depending on how close to the polar circle you are you get little or no sunlight in the winter, and little or no darkness in the summer. So if the hypothesis is true then epileptic seizures should be more common in the winter in those parts of the world.

This Truths/Myths layout was really fun! Thanks for all your hard work on it!

Sleeping less, and less deeply is a sensible response to cyclical changes in an animal's environment that favor its predators - explains why we usually have trouble getting a full night's sleep during The Purge.

The atmosphere and ocean aren’t the only thing affected by tides. There are also “earth tides” and the actual ground bulges up slightly below a full moon

When I saw the thumbnail to this vid I thought "WereUterus"

I find comfort and coziness sleeping with the full moon shining through my bedroom window.

This KZfaq channel is one of the best around there. I like nearly every video and watch them more then once.

For #1, wouldn't it also make sense to sleep lightly on nights when we're more likely to be found by predators?

#3 "When the moon hits your coral photoreceptor, like a big pizza pie, that's amoré." Doesn't quite have the same ring as the original...

Since about 20-25 years ago I have been doing this, quite passively: when several friends or other people mentioned within a timespan of a few days (or a week) that they had their period, I checked the state of the Moon. The vast majority of times the periods of very different women in very different places happened to occur during Full Moon, or not far before that nor far later. I checked this out probably hundreds of times. It's tempting to consider that I was just checking this when there was full Moon. But it's not the case because it happened in the other direction: I had no idea what stage the Moon was at until I checked it up after finding the "strange coincidence" that several friends of mine living in different cities or countries had their period at the same time, or at least in days pretty close to each other. I can't remember any (or almost any) case in which 3 or 4 of them had their period "synchronised" on new Moon of any other point but relatively close to full Moon. So, maybe others buy your "mere coincidence theory". But I don't. The comparison to chimpanzees seems very tempting when I serves us to "prove us right", apparently. Not when it doesn't. Cheers!

Hank the champ, a great 2020 to you and all of your team! Yes!!

Omg circalunar rhythms is such a cool idea! 🌑🌒🌓🌔🌕🌖🌗🌘

Interesting video. BTW, it's called "Mass Coral Spawning" Hank............... 👍

Well I have long been aware of a good large portion on this subject. Though there's always opportunities to learn more. So yes.. I learned much. I also enjoyed how you broke em down and conveyed contrasts between each. Well done!!

Y'all are sooooo close to 6 million, congratulations that's an amazing accomplishment and I can't wait to see what other cool science I will learn in the next year's 🎉🎉🎉🎉

"... one study suggests ..." The mating call of clickbait science journalism

Soooooo....the full moon doesn't affect behavior, but does affect sleep? Wouldn't less sleep affect behavior?

I like this truth/myth format! I hope you consider doing the same with other topics.

I mean I would be interested to test out my own theory here. Hear me out. Hunters do actually do more hunting with moonlight as it makes it easier to see. Since we have evolved along with the moon since always wouldn't it be reasonable to see if there is a correlation between hightened hunting (aka killer) instinct and the moon? The same would hold true for the hunted, with hightened sense of fear. And we as humans have been both hunters as well as prey. Again it would be interesting to see if remnants of this does affect out state of mind durring lunar phases. Or it's all not. Just a theory.

"When you are having a weird night and strangers are acting stranger than normal" LoL

Vegeta: THE BLUTZ WAVES

*"When the light is right, IT'S SPAWNING TIME!"* At 4.38 I just can not get over how HAPPY Hank looks when he announces it! 😂😂😂😂😂😂😂😂😂😂

They say sailor scouts fight evil best during moonlight, and succeed most often at winning love in daylight.

no one: thumbnail: _MOON _*_O V A R I E S_*

My doctor gets more patients during the full moon. And our emergency department always plans for extra staff during the full moon. So there.

By my experience, yes, a full moon does sometimes make mating easier.

I love you guys, thank you so much for the videos

ER’s and paramedics deal with “crazier” situations and don’t have a comment saying “I’m a nurse and I don’t see anything crazy” lol

I'm a romantic, and I love full moons. The best time for a midnight stroll. The lunar rhythms would explain why the elderly tended to go nuts at the senior home I worked at. Thank you for the knowledge!

Only with the speed of 1.75 can one not get bored with SciShow's videos

Question regarding 1 - Humans get less sleep. What else - besides visible light - does the moon reflect with the same cyclic variation which might affect humans (and other animals), but cannot be controlled/blocked as easily as visible light?

There was once a boy in year 8 who I heard comfort his friend by saying “don’t worry about it man. It’s the 18th, all the girls are on their period”

Whoa that outfit. I like the change up. There is such a thing as “low tide rain” in some culture language.

I’m surprised y’all didn’t mention babies being born on the full moon. I’ve always heard that it’s much more common by my nursing friends, I’m not sure if studies support that however.

For whatever reason.. i often get a headache during a full moon, or i feel very strange and awkward. Its a real thing, even if people claim its a myth. I often don't even know its a full moon until i check outside. So it ain't like i saw it, and i thought.. oh it will make me feel bad and then it does cuz i think about it. It happens even if i'm not aware of it.

Also makes "tides" inutero. When I worked in OB we were always slammed every full moon.

The word “moon” DOES NOT COME FROM Latin, it comes from Proto-Germanic, and shares a Proto-Indo-European ancestor with the Latin word mens (i.e. the words are COGNATE).

Hank's shirt goes too well with the topic of this video. Palm trees in moonlight pattern FTW.

Thanks for another awesome video!

All I know is when I see a full moon my first thought is... _"do ANY plumbers own belts?"_

It's funny that this video got posted because my D&D yesterday involved werewolves and the coincidence amuses me

This is going to be a different topic. I've been a subscriber of this channel for over 5 years and I plead to SciShow that if you can make a video about what's happening in Puerto Rico with all the eartquakes, please please please make one explaining in depth of everything that's happening. There has been a lot of misinformation to the public of what's really going on, and a video of you guys can clear a lot of those myths and straight up lies. I saw the "Megaquake" video a couple of months ago and I found it to be very insightfull. It's been 2 weeks on non stop quakes ranging from 3.00 to 5.50 including 2 that were 6.00+. Like i said, I've been a sub for over 5 years and love how all of you explaing your videos. Keep doing a great job SciShow. Hopefully i'll ser a video in the coming weeks about this topic.

Finally another great video!

The power of the moon? Sailor Moon had us thinking otherwise

about the 1st one humans probably sleep less on full moon due to the fact visibility isnt hindered, would make predators more active and may have cause a evolution adaptation to stay light on your toes during a full moon

The indigenous people that I lived with while volunteering with the Peace Corps told me that you have to plant and harvest crops according to the moon's phases. I have always been curious to know if this has any scientific validity.

My grandmother didn’t believe in the full moon making people crazy until she started working in a nursing home with people with Alzheimer’s & dementia. After that she believed in it for the rest of her life. My aunt is nurse & works in the maternity ward & she says there is so many more births during the full moon. & my mom is a pharmacy technician & she worked in a hospital for 19 years & saw first hand how much more crazy people got during the full moon. Now she works at a Sam’s Club pharmacy & she says costumers get crazier during the full moon. The stories she has omg 😳 so, sorry, but I whole heartedly believe there is a correlation between the full moon & peoples behavior. I also have 2 other family members (a cousin & uncle) who are nurses so I know so many people that have seen the effects of the full moon on people to not believe it. It’s crazy. Also if people aren’t getting as much sleep as usual, it’s not that surprising that people would act crazier during full moons. Also my other grandmother recently passed away 2 months ago. She had dementia & I just looked up the moon cycles from that time. There was a full moon when she started getting sicker. She had a big scare on Monday November 11th & I know this cause that was exactly 2 weeks before she died. The last time I saw her was actually during a full moon on Tuesday November 12th (I know cause I rushed to see her the next day after the scare) & she was acting very strange to say the least. I know part of it was all the drugs she was on but I’d never seen her act that strange before, even when she was on drugs before. She was saying the strangest things & my uncle was there with me by coincidence (I got out of school the same time he got off work & showed up at the same time) & even he didn’t know wtf she was talking about. I can’t even describe it. It was like she was in this other world where she had been taken hostage?...& tied up?....& held down?... & dragged out?...I have no idea. & she was saying she hadn’t slept it days (she’d been asleep all day the day before because of the scare so the hospice nurses gave her a bunch of morphine to knock her out so they could work on trying to save her) & she did NOT want to eat, she was adamant on going to bed (it was like 4:30pm) to the point she was starting to get angry (her familiar angry voice that I hadn’t heard since before the dementia was coming out). Now I’d heard her say “i haven’t slept in days” before & knew it wasnt true cause usually all she did during my visits was sleep. But I’d never seen her so adamant about going to bed RIGHT NOW & refusing to eat like that & about to throw a fit (my uncle & I left before it got ugly 😬) It was scary & so sad to for me & my uncle to see. My uncle & I just kept looking at each other like “what is happening???” & I hadn’t seen her that talkative in years. Usually all she did was sleep. She actually passed away on Monday November 25th & Tuesday November 26th was a new moon so 👀 idk it’s all so strange.

"Glow like your shoelaces under a blacklight" What have you been doing with your laces?

I've seen and heard strange things, but I've heard Stranger Things...

This channel cracks me up. Such inept Science it brings me to a crying laugh. Going to get whiplash from shaking my head.

Great episode. Very interesting stuff

Literally says dung beetles can find their way by the Fricking vibrations of polarization of sunlight. Proceeds with this isn't that impressive.

Work in an ER on a full moon. Makes you question it!

I always seem to get my period🩸 when the moon is full.

hank: do full moons trigger seizures? me: * slight panic * video: myth me: * relieved * hank: but they do happen more often on the last quarter and darker nights and are somehow linked to lunar cycles me: * back to slight panic *

That shirt... 👍🏻

That thumbnail was weird when I first looked at it I thought it was a tree of some sorts but I get I now

Cool episode!

Really good episode!!
