  • I knew it! About once a month I suddenly have a few nights when I can't really sleep well for no apparent reason. Except for the full moon. I knew it had to be it!

  • 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.

  • they say that you should trim split ends of your hair during full moon because it somehow makes your hair healthier, I think it may be because of the air or something because hair tends to get frizzy when it's low pressure

  • Here is anecdotal evidence for further study of human menstrual cycles and the moon's cycles. I happen to know many women who lived or live in off-the-grid hippie communes with no electricity whatsoever. These were communities with 20 people or so. The women would all menstruate at the same time, and all during the full moon. Perhaps there is something in living with the electromagnetic fields of tech that throws this off (if it isn't a coincidence) or with being able to turn bright lights on at night (which would be retinal influence and not an electromagnetic one) or perhaps there is some combination thereof.

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

  • This presenter has obviously never worked in a hospital emergency ward, as a paramedic, police officer or in a psychiatric ward during a full moon, I remember a high care aged care worker telling me that many of the advanced dementia patients act up during the full moon, the majority of people may feel no lunar effect, but people who work in the mentioned areas most definitely see an effect on a minority of people.

  • The menstrual cycle "mystery" HAS a scientific explanation. Unlike other primates, early humans hunted at night... by moonlight. Well, the men did at least. That means women who were most fertile every time the moon wasn't out had more offspring, passing down those genes. If human's cycles stayed around the length of 37 days, then fertility would align far less often with their greatest opportunities to mate...which happened every 29 days. Our ancestors that had longer cycles got bred out of existence.

  • dude... did you do any research?? your 1st statement couldnt be more wrong! on the full moon they always had an extra nurse scheduled in our emergency room BECUZ there were routinely MORE PATIENTS! ??? OUR BODIES ARE 97% LIQUID?? HOW! could we NOT be affected!!! HELLOOOO!!!!!!

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

  • 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?

  • One thing I would like to know about that research on lunar cycles and menstrual cycles using the data from the app is "were those women on hormones?" Because since I stopped taking the pill I can totally connect my cycle with the moon cycles, it's really amazing.

    MBTHAISMBTHAISMonth ago
  • Yeah? Try working in an emergency room, then talk about it again....

    Eyvonne HammondsEyvonne HammondsMonth ago
  • The reason why the data for that period tracking app didn’t correlate with the moon is because they were all on the pill! Makes no sense to me why you would need an app to track it if that were the case but...well all of us don’t work the same.

  • Try being a police officer during a full moon. Compared to any other day of the year. It hits fan.

  • not leftovers man, the human body has minimum 60% water, and on top of that there is a small magnetic bone at the bridge of the nose called, I believe it is the ethmoid. but it is just pure nature, not leftovers.

  • Only one true thing you need to know about the full moon it marks the middle of the month, if it's a full moon you know it's the 15th.

    Miriam BabiMiriam BabiMonth ago
  • A cow or a heard of cows will always face north or south when resting. Dogs prefer to face north or south while pooping. It has to do with the magnetic poles. I like weird facts... that's why I'm here. Also you can tie a chicken leg bone in a knot by soaking it in vinegar for 24 to 48 hours. I have never tested this so It might take longer or shorter, or it might just dissolve into goop. Thank my dad and his unlimited well of useless information. I'll take his word for it.

  • worst one yet

    Jeff JJeff JMonth ago
  • At no.7 you miss the fact that its know for thousands of years that the moon is realted to our emotions. It means that the moon itself interferes with our brainfunctions. You missed the important fact that people seem to eat more eggs during full moon or the werwolf phenomena were undealt emotions rise up to be unleashed. Our brains is related ti the univrse which includes all our planets in our solar system. Your scinetist not having an answer but making up an excuse makes no sense. Listen to our ancestors. Maybe you will learn something. It is called numeroogy and astrology. GL & HF with your discovery of our true reality. Our ancestors already explained eveything to us to its finest details.

  • So, does the moon make it more difficult to fly for birds/insects when it's overhead thanks to the air pressure, or is it a little simpler due to the gravity? (I mean mechanically)

  • Hank seriously i love your Content and i wish SciShow would get all the german ARD/ ZDF Money (Rundfunkgebühren) Broadcasting of "Free Radio and TV" While whole World understands Digital, and Password Protected services, German LAW dosnt (Internet is still newland) So we still pay more than 8 Billion Euro for crappy content no sensfull guys can watch. Get yourself at least some percents of the cake :D You deserve it

  • Lmfao try working in a mental hospital, nursing home, or prison. Lunar gravitational pull in some way? Anything is possible. I get dizzy right before every full moon without realizing it's about a full moon.....and I mean really dizzy....I have an autoimmune neurological encephalitis....so I know when I'm having a weird dizzy moment....and these are unique.

  • 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!
