Dh changes when a full moon

Not in a werewolf way and i’m not a woo type of person, but I’ve noticed a few times (going to have to start writing it down) that on the build up
to a full moon, he can be very moody and not nice sometimes and the day after-few days after, he’s back to himself, but much nicer-kinder

It’s happened too many times now to feel like a coincidence

Am I the one going mad?

My DS had epilepsy, and his seizures were more frequent and prolonged at a full moon - I didnt see the connection, just tracked the data for his epilepsy nurse to review, she spotted the connection instantly and said it was common in her experience - told me to buy a diary/calender with a moon cycle to help manage symptoms/future plan. She was spot on, when I back filled the info aligned with moon cycles.

Amazing how we find reasons for men behaving badly!

'AI tells me this is a myth and there is no such data'

I bet that was Claude. He can be a bit unreliable at certain times, he says it's not his fault but due to the spring tides. We all avoid him in the canteen around these times.

I have heard (although never found evidence as such) that’s where the term Lunacy came from.

I’ve always believed it because the moon affects tides due to gravity and humans are full of water 🤷‍♀️

For me though I’ve seen the evidence. And Antonine PO who said about seizure activity increasing over a FM. That’s springing deal with in my job and have seen a correlation.

That is where the term lunacy came from, the theory was that moons 'luna' and tides caused madness.

In the same kind of eras where hysteria was why women were mad. The theory being that the womb (hyster) was wandering around the body making women mad and you could coax it back into place by putting tempting herbs and other things up the fanny or make it go back into place by eating horrible things that would scare it away from the upper body and back into the lower body.

Hysteria in psychiatry later morphed to mean physical symptoms caused by psychological issues which could be experienced by men or women.

My Great-Grandad was in the 1st WW from 9th September 1914 as already in the army. At the battle of the Somme among other horrors of 4 years in the trenches.

Discharged as medically unfit 6 months after the end of the end of the war due to 'Hysteria aphonia' - he was washing bandages still in France and lost his voice. Had psychotherapy which brought his voice back but with a previously unpresent stammer which resolved with more therapy.

Now we'd call it FND or PTSD, not hysteria.

So all bollocks really in terms of what the Greek medical terms meant.

yeah, but you don't know he's not a werewolf, he could be, Awoooooo

Things that happen to men…?!

Things that can make women more sensitive and less tolerant of our men.

DH could be seen as moody back when I was young but he would characterise it as staying out of my way.

Isit2026yet · 01/08/2026 10:53

@Touristtrainstuffedtothebrim it’s called the lunar effect, while not widely proven by psychologists there are many who've studied it.

Nope, it isn’t me.

I worked with someone who was married to a psychiatric hospital administrator. They always scheduled extra staff at full moon. We are told it's all a myth but if you ask those at the coal face they will tell a different story.

But again, why isn’t there data to back it up?

You mean 'not at all proven' despite being widely studied.

No I mean it as I said it. My mum is a psychologist and there are many papers on the lunar effect.

Squirrel60 · 01/08/2026 11:15

You're not going mad at all!

A lot of men are affected by the moon cycle because of their natural manly hormones, and the same with women with periods and menopause.

That includes teenagers, both male and female, because of hormones.

It can be scary for those going through it and also those who see it in others, but if he's behaviour continues, then gently suggest he see a doctor who might be able to put him on something.

Yeah I call them "pressure headaches", my mother gets them too. They are not like normal headaches.

Bloody sore eh!

Flannelfeet · 01/08/2026 11:18

Millytante · 01/08/2026 01:34

Same here, when the air pressure is altered. Like I’m very tightly wrapped, head to toe, in clingfilm. Same feeling inside my skull.
When significant rain is approaching, my right leg aches to the point of my almost weeping.

(This began in childhood, when all the paediatricians in London my mother dragged me to see asserted that this was ‘growing pains’. Since it was my right leg alone, I was convinced that only that limb would keep growing)

I hate it, its been quite bad this year with the muggy weather.

🤣 I couldn't stop laughing at the vision of one long leg and one short leg.

WerewolfOfLoudon · 01/08/2026 01:49

My inappropriate hair growth is due to PMOS (formerly known as PCOS) but the lack of sleep during the full moon might just make me go howl at it someday. It's not something I have tried yet.

@Flannelfeet I'm with you on the headaches too! I love thunderstorms because of the pressure release they bring. Can you smell incoming snow too by any chance?

@Touristtrainstuffedtothebrim Is he struggling with sleep? It is more common than you would think for the full moon to cause insomnia and the resulting irritability. There have been threads on here about it, obviously it's mostly women's experience. Close friend is a psychiatric nurse and he struggles to sleep at the same time, while dealing with the most volatile cases at work.

Funny you say that, i feel like i get a fizzing in my nose when the snow is on its way.

I must be some sort of weirdo, 😆 🤣

Many papers on the effect reflects the societal belief it exists, it’s not evidence it definitely exists. Data. Data. Data.

What hormones?

What medication would a GP be giving someone who thought the full moon is effecting them?

My friend’s brother, a paramedic for 15 years and a very sensible guy, insists that they get a spike in call-outs when there’s a full moon for things related to MH, brawls, reckless behaviour. etc, and that’s there’s definitely a correlation.

He insists, and yet there is no data. Confirmation bias.

kattyjean · 01/08/2026 11:31

I came into this thread with assumptions and have left it frustrated. It would be very easy to prove the lunar effect, it would be SO easy to demonstrate it with quantitative data if it existed. There is enough incentive in society to want to prove it, and yet it hasn’t been, honestly think people need to use their critical thinking skills a little here. It’s an interesting theory, we want it to be real, but if it was real, the data would stack up. Instead the lunar effect appears to be a stronger demonstration of confirmation bias than anything else.

I guess he could prove it by keeping a record of all call outs for a few months and checking with the moon phases, although he'd also have to allow for times that are known to be busy anyway and the different times of his shift patterns.

I assume long term paramedic call out and A&E records are easily available around the country and even the world already, so if this is true, it should be very easy to prove, actually.

No - things that happen to women that might affect their mood and thus also a) the mood of other people in the house and b) their perception of other people’s behaviour.

Growing up, I could always tell when my mum’s period was due and we would both be a lot more irritable with each other around that time. She was more annoyed with me about little things than she usually would be, and I would respond by sniping back.

Obviously I was also having periods myself for most of those years, but my mum and sister always struggled a lot more with PMS than I did. My dad used to say I was the only one whose cycle he couldn’t have predicted.
