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.

should be interesting to see what happens when humans get between Mars and Earth and they have no magnetic field around.

Maybe my menstruation influences the moon instead of the other way around?

A deeper connection to women would help here... thankfully more people are studying the wisdom of the natural hormone menstrual cycle.

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!

"Orient" is not a verb, please stop treating it as such. "Orientate" is the correct term, you are obviously aware of this as you said "orientated". Please stop mangling the English language. Thank you.

Oh, when they do it it's called an underwater snowstorm. When I do it, my wife tells me to sleep on the couch.

Not a myth. I've worked in call centers for 14 years and people get crazy during a full moon. I know people in the medical care field and they say their patients are whacky too.

What about hair growing faster or slower depending on the moon phase of the time it was last cut?
That one is a pretty popular myth here in Italy

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 *

Grunion runs are affected by the moon. The grunion swawn only at the highest tides which are conteolk by the the moon. During the highest tide they run or in other words spawn. The eggs remain in the sand until the next high tide when they hatch.

Sorry to be pedantic, but these are MOON FACTS not FULL MOON FACTS. Bad title.

I doubt the menstruation study took into account the widespread and common use of contraception. It would be harder to get a large number of women not using contraceptives. That would be the study I would read.

Circuluniary rhythms could explain why women's periods on average are on a 29 day cycle when the moon is also on a 29 day cycle. Obviously not every women get's their period on the full moon and not every woman has a 29 day menstrual cycle, it's just the average. But if you remove a woman's sense of time (take away all natural time tellers, clocks, sunlight, etc) her period will be thrown off so your natural body clock could use the phases of the moon to know when to do menstrual stuff. I don't know about the chimpanzees, maybe they just don't notice the moon or count in days instead.

Ok, so you start out by saying a full moon doesn't affect people's behavior, and then immediately state it affects both the quality and quantity of sleep....which would directly affect human behavior. Am I missing something?

"Research actually has not found any connection". So does that mean it is definitely a myth? If you cannot prove something, does that automatically disprove it? You are implying that lack of evidence is evidence of nihility. Or does it mean that the research method is weak?

More babies are born under the full moon. Ask any experienced nurse in labor and delivery.

there is always a different outcome between science tests and practical real world. You are more likely to get people acting crazy on a full moon. Control ab tests will always alter the outcome

If women did not have all the chemicals running through it, you would find a greater correlation with the moon cycle.
Not that everyone will start and stop their cycle on the same day; but you can correlate a daughter's cycle from their mother's cycle.

This got me wondering about why scorpions would glow under UV light if it was something that put them in greater danger of predation. You'd think that natural selection would weed out this trait. Is there a metabolic reason for this trait? Is there something that is either beneficial or so necessary that it's let this trait survive?
SlyPearTree - 4 kun oldin
Their predators do not see in UV, at least I don't think so.

If you watch the moon cycle you will bleed on the full moon. This is pretty well know in celtic communities to reduce period pain and shorten the days as drastic as 4 dsys less. You do not need to do anything other than be aware of the moons current phase. Nearly everyone I have ever challengeed to try this alignment do agree in the effects.

What about the belief that full-term pregnant women are more likely to go into labour on the full moon? I've heard some midwives say that's not true, but that there is a spike in women being admitted to labour units when there is a thunder storm. Thoughts?

Internal worms and parasites in the human body could be affected by the moons place in orbit. Causing them to release hormones in the body that could cause a disruption in the human hormones. This would cause erratic behavior if there was a over abundance of worms and parasites.
