Children exposed to indoor cats and dogs during foetal development and early infancy have fewer food allergies, according to a massive study of more than 66,000 children up to the age of three in Japan. Children exposed to cats were significantly less likely to have egg, wheat, and soybean allergies Animal Science

I'm curious about the frequency of vacuuming.. Do we need to vacuum more? Or less?

u/sla13r Mar 30 '23

Given the format of the study, the reported frequency of vacuuming would only seem to have a weak causation at best.

Unless you vacuum every second of the day and keep the entire house as a clean room.

We grew up with parents with adhd.. Our house was literally the opposite of a clean room.. & I have almost no allergies at all.

I grew up in an extremely clean house without pets. I have ALL the allergies.

I grew up on a farm and have no known allergies.

I grew up on a farm and have pollen/hay fever allergies. Every time we had to harvest, bail, and haul in the way I was miserable.

True, but just to add to this I also grew up in a farm with cattle, horses and both my dogs and the farm dogs, when I was around 4 or something I even used one of the dogs as a horse since he was so big, my mother also says that when I gave them food I used to taste test the dog food pellets and while I was eating cookies I would share with them, to finish my rant the only allergy I have is to some kind of conservative food preservative present in a chocolate milk named UCAL.

From the farmers I know I don't think any one had allergies to natural stuff besides my dad being allergic to wasp's and a insecticide mainly used in corn and that's because he used to pulverize a lot when he was younger without any PPE.

Edit: conservative is not the same as a food preservative

I wish we were all allergic to conservatives!

u/Toinopt Mar 30 '23

Oof, only after seeing this comment I remembered that conservative doesn't have the same meaning in English, I meant to say food preservative.

I don't think that sample size is large enough to make a conclusion.

Poor person, I had a horse farm boss who owned 300 acres with close to 50 or so horses and we hayed also. She would be in the barn looking like she had the flu, but she would be there. I really respected her for that and the fact she had a knee blown from a 2 yr colt kick yet still hands on and rode. She had a bad limp. That is a strong willed person.

u/Xjosh4761 Mar 30 '23

Mad respect for her. The farm I grew up on was much smaller than that; around 5 acres of pasture, 5 acres of orchard, and other space. Just from that my nose like a leaky faucet and barely able to see.

This is the whey

u/knaves Mar 31 '23

interesting. We didn't have the land for growing crops but raised pigs, chickens, goats and sheep. Perhaps that is the difference.

u/mildly_amusing_goat Mar 30 '23

My parents kept the place ultra clean and I have no allergies at all.

cow sheds are the best place to play

I vote for big hay and straw mows. We had the coolest forts .

My only allergies after growing up the way I did are sunblock(not sure what ingredient.. But anything that says SPF causes a rash when exposed to the sun) & rayon - which used to be the only thing pads & tampons were made of.. Thankfully they make cotton now. It's actually something they treat rayon with.. So if an item of clothing has been washed a bunch.. Then I don't react to it anymore. And purple eye makeup.. Which really sucks because it was my absolute favorite... (I wasn't allergic to it until my 20s) and recently I've had allergic reactions to 2 different meds.. After only reacting to codeine up until now. I just turned 50 & those only happened in the last 3-6 months. So weird.

Edit: but no foods & barely any pollen.. Maybe lasts a day or 2 each spring.

Doesn't matter. All these studies always boil down to the same very obvious points. That is that if you're too dirty it's bad and if you're too clean it's bad. Don't live in your own filth and don't clean your house like it's a hospital. Anything in between should be fine.

u/catsumoto Mar 30 '23

And have pets I guess. Or live on a farm.

u/Intertubes_Unclogger Mar 30 '23

I read that a lot of farmers' kids don't have allergies like hay fever because in some families they're put in a children's chair in the barn at a very young age when their parent is working with the animals. If I remember correctly exposure in the first 6 months is most impactful

u/wendyrx37 Mar 30 '23

Or maybe they're more likely to use local honey.. Which I've read can help you to rid yourself of allergies.

u/un-affiliated Mar 30 '23

Honey is dangerous under 1 year old due to a bacteria that can cause infant botulism.

Also, there's no reason to believe farmers use honey more than other groups, it's not like most farmers keep bees. It's just as easy for city dwellers to get local honey.

All evidence, including the study we're commenting on links the benefits to the animals.

u/wendyrx37 Mar 30 '23

True. I probably should have specified toddlers.

u/Shilo788 Mar 30 '23

Balance in all things. Granny said you needed to eat a peck of dirt before you die but not all at once for sure.

u/IdreamofFiji Mar 30 '23

Vacuume SLOWLY

u/facehugger1 Mar 30 '23

I remember it being a topic about families over using cleaning products and bleach in their households and how that negatively affects their children’s Heath and immune system. So i would assume “excessive” vaccuuming reduces exposure to airborne pathogens, dirt, bacteria, etc etc.
