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 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.

They don't though.

If they did, they'd have the data to support it and they don't.

There are plenty of people who think vaginal douches, onions taped on to a body part, prayer, drinking breast milk or drinking their own piss cures cancer.

None of it backed up by any actual studies.

One of the latest trends is deep cold plunge baths. Loads of people saying it's cured their anxiety or depression. Zero evidence in studies to say that's true.

Cognitive bias and placebo effects are very real. People find the evidence they're looking for and discount the evidence that refutes it. Not even consciously, they just do.

That's why we have stringent studies, often double blind which continually find it's not true.

And before any woo manifesting people say the placebo effect means your mind is so powerful you can cure yourself if you believe you can.

No, that's not what the placebo effect is. .

The placebo effect is that someone can believe they feel better because they had a pill, or an IV or any other intervention. Particularly in conditions that can be influenced by psychological states like anxiety, blood pressure, low mood, and so on.

So in studies for asthma for example. The people receiving a placebo often report feeling they could breathe more easily but their peak flow would say no they weren't, it was just their perception.

Give a type 1 diabetic a placebo instead of insulin and they will be very unwell quickly even if they believed it was insulin.

We used to say when there’s a full moon out there were more arguments in the shop, kids being stroppy, angry adults etc. it is honestly a thing!!!!

TheHonestSnail · 01/08/2026 12:13

And there is SO much data to support other things.

Some crimes go up in the summer. Often violent ones as more people are out and about and drinking. Burglaries increase due to more people out and more windows left open.

Antisocial behaviour with gangs of kids, bikes being ridden up and down, noise complaints etc goes down dramatically in winter months as it's too wet or cold

DV and child abuse increases during school holidays, particularly at Xmas. Because families who usually have space from each other now don't. Alcohol use increases on holiday and at Xmas.

And DC more vulnerable to child criminal exploitation and child sexual exploitation as have more free time out and about or online and don't have the safeguards that may exist at school.

Domestic violence increases during the world cup due to heightened emotions and more alcohol.

NHS deaths increase the 1st week of August when newly resident Drs start their rotation

A and E attendance dips on Xmas day as most people spending time with family and not wanting to spend time in A and E.

Divorce applications, GP appts, MH referrals including alcohol and drug services spike in January as people making new choices in a new year, often after a shittier Xmas that made obvious problems they ignored the rest of the year. Or just thinking something they put off for months, they should get looked at now in the new year.

Alllllllll these things can be evidenced by actual data.

There is zero to support the ancient belief that the full moon changes people.

Yet you'll still have people saying 'well it's definitely true ime'.

It isn't.

VikingLady · 01/08/2026 12:29

He’s suffering from tides!

More seriously, I have known several midwives who say the moon cycle affects birthing, although I no longer remember exactly how. Are there any midwives on here who could chime in?

These days almost all of my circle have kids with SEN. A significant proportion say their children don’t sleep well when it’s the full moon which directly affects their behaviour on subsequent days. And yes, they mostly have black out blinds.

Om83 · 01/08/2026 12:30

Not behaviour exactly but just wanted to add that when I gave birth to my DS it was a full moon and the hospital said it’s always busier/less beds every full moon with ladies going into labour because of that- so much that they actually rota it in to have more staff on shift!

MeridianB · 01/08/2026 12:45

If he’s a Cancer or other water sign I totally buy this - once had a boss who was so changeable around moon phases we used to put them on a whiteboard and use them to help plan for requests such as more funding or staff. 🌓🌕🌒🌛

Loulou4022 · 01/08/2026 12:53

Yep I believe it’s a thing! One of my friends partners is like this! The kids at school their behaviour is worse around the full moon too! Throw in a windy day and wet play as well and it’s hell on earth!!

Bakeittillyoumakeit · 01/08/2026 13:17

Could be worse OP, he could turn into a werewolf on a full moon.

kattyjean · 01/08/2026 00:12

Is there anything other than anecdotes though? It really interests me but I can’t find anything concrete and it doesn’t seem like the kind of thing that would be hard to evidence in MH, police and medical settings.

If there's no money to be made from it, who is going to fund the research? It's usually drug companies doing the research. Just because there's been no research to say it's true, doesn't mean it isn't.

OP the word "lunatic" exists for a reason. Luna = of the moon.

DollyPumpkin · 01/08/2026 15:21

People are absolutely affected by the moon it’s where the word lunatic comes from. I work dealing with anti social behaviour and its definitely busier when it’s a full moon!

clearlyy · 01/08/2026 15:23

i definitely believe the moon affects everything. If it affects the tides it affects us too.

sweatybettytoday · 01/08/2026 15:29

I was a medical scientist. (Ie worked in the lab) overdoses def went up during a full moon and so we’d put more reagent onto the machines to test for it. Most emergency services staff would probably agree that behaviours change too

pinkandwhiteroses · 01/08/2026 15:32

I work with animals and the full moon definitely impacts their behaviour. Just as they're often impacted by the air pressure before a storm, for example.

It's definitely a "thing" to be impacted by your environment.

I don't follow your logic

Do you think the tides only change once a month at full moon?

If your logic were correct, there would be few or no studies on this, but it's not that the studies haven't been done! They have been done, across anthropology, sociological, criminology, psychiatry etc, and they overwhelmingly show no evidenced link between higher crime, higher violence, higher psychiatric admissions and the other correlations claimed by superstition and folk belief.

Lolalady · 01/08/2026 18:02

My late dear dad spent the last 4 years in care. The carers told me that a lot of the residents became difficult at full moon. There is also a condition known as sun downing - people with dementia become unsettled at sunset.

Single50something · 01/08/2026 18:05

My mum is bipolar and a colleague noticed that her difficult episodes happened around full moons. Id not realised but now do...and if she is going to be difficult with me, it does tend to be full moons. Eg.at moment...
The term lunatic obv comes from the moon affecting people
A policeman friend said the police notice it

Thisismynewname23 · 01/08/2026 18:25

This is absolutely a thing, o noticed it in my teenager and when talking about it to a friend who is a policeman he said the cells will be full on a full moon brings the crazy’s out, other friend who is a teacher said she can absolutely tell when it’s about to be a full moon all the kids especially sen are affected in her experience

There is loads of research on the topic, spanning decades. It just doesn't support the claims of moon-induced behavioral changes.

Multiple large-scale medical reviews and emergency room data analyses confirm that lunar phases do not change admission rates.

Large studies have shown no statistical pattern connecting lunar phases to total crime volume.

It's a superstition.

Yes, and some enormous meta-analyses, collating the results of many studies.

Holdinguphalfthesky · 01/08/2026 18:51

I think the moon affects behaviour (teacher here too) and so does windy weather. I was really emotional on Wednesday, quite unlike me, and it was full moon then. Just one small example.

My Uncle (donkeys years ago) was described as Moonie because he changed and became more moody and aggressive with the full moon - I seem to remember as a child it was a ‘known thing’ for people, mainly men, to be moonie.

No, things that happen to women that make behaviours in others less tolerable and more annoying than they would be at other times.

I hate to say it but maybe it's not him, it's you? Grin

Oh god yes, before I went on HRT I was convinced I would need to divorce my husband, I hated him.

Ozcams Razor op.
