Armpits & menstrual cycles

Often a group of women in close contact find their periods synchronized. 35 yrs ago in a study, women wiped armpits with alcohol sponge and then other women were to sniff the sponge. One person was an "earth mother" meaning she didn't bathe. By and by the group, after smelling her armpit odor on the sponges found their cycles synchronizing with hers.

So ladies: have you lived/worked with other women and found your periods synched? Or not?

The study reference is needed for your claim.

Here is a review article.

menstrual synchrony is a myth

So who needs scientific evidence....isn't rumor and old wive's tales more reliable?

Sometimes scinetist have really spare time to loose....

I did not have my periods at the same time as my mum when I lived at home with her and I have not heard of it with my friends and their sisters and mothers either. I do not think it really happens. It could be coincidence but I do not think women start having their periods together just because they live in the same house or they have close contact.

This is a known fact, BUT, the women have to be living together isolated from any other human contact. The thought is that somehow their bodies/cycle align as they recognise there is a threat to reproduction due to no male, or other human interaction.

Really???

Got a REAL REFEREED scientific journal article WITH STATISTICS?

Don't bother with anecdotal reports.

My two daughters and I never aligned, plus my periods start every 27 days between 10-11 am (you can set your watch by my periods) and their periods are 28 days. Due to different cycle lengths, our periods have overlapped at times, but that ISN"T the same as being synchronous.

It's a pain in the butt not to be able to count down four weeks on a calendar to know when it's coming, especially when you're planning something months in advance and you want to be on blood-free days.

Now there are phone apps that will tell you exactly.

I have never exactly synched with another girl I lived with. My sister and I shared a room growing up and ours are a few days apart. My sister starts a few days after me. I had a roomie in college and we were not even close. Then I had a girlfriend for a few years and our periods were close. Now my sister and her girlfriend rent from me. My sister still starts a few days after me and her girlfriend starts about a week or so before me. It's not hard for any of us to tell when another is on. It's like the only time someone wears panties here. At least we don't get bitchy.

It's easy for periods to overlap or to be a few days before or after the other. That always happens because periods are 4-7 days. One person's starts, another person's starts at another time. BIG DEAL. Roughly 20% of fertile women are menstruating at any given time.

Synchrony is when they start out at different times and then after a while overlap exactly.

That doesn't happen.

This is a known fact, ....

I don't believe there are ANY known facts - only those that have been proven.

Pet peeve of mine, but I see assertions like this all over the place.

Do these apps have a probe that requires rectal temps? I hear that is very accurate for determining when menstrual cycles start. Can't you also take a pill like a birth control pill and either alter or skip periods, even for multiple months? I'm very sad that most healthcare professionals don't use rectal temps or enemas anymore. It's a sad sad day

I don't need a temperature to know when my period starts. It's every 27 days between 10 and 11 AM.

The phone apps are calendars for your period. The basal temps are for ovulation.

Seriously, that's ridiculous.

One person was an "earth mother" meaning she didn't bathe. By and by the group, after smelling her armpit odor on the sponges found their cycles synchronizing with hers.

I had to stop laughing before I could reply to this thread. Seriously, they all sniffed some 'Earth Mother's' armpit sweat on a repeated basis so their periods would synch up? 😁 HAHAHAHAHA. 😁

As for the rest of you: do you people not know when you're being trolled?

OP go back to 4chan/b/. Don't worry, a lot of us are right behind you. And well done sir!

I don't think he was mentioning this purely for diagnostic purposes... and on that note I have to agree with him, whole hardonly. Now turn over, hold still, and think of Old Glory. 😁

Doesn't anybody get jokes anymore?? 😃 😃

Yes, I do, but I think he was serious!

Now Susie I'm calling bullshit again. I think you know I was joking. Bad girl

Periods happen to virtually every female for many years of her life. I grew up in close contact with three other females (four of us including myself that would be) and I have worked fairly closely with countless other females over the years. Each of us had periods lasting for probably an average of 5 days. It would then become statistically MUCH more probable to be having my period at the same time as some other female in my circle than it would be to be having my period when no female in my inner circle was having a period at the same time. Did we synchronize exactly? I honestly don't know since normal conversation within my circle of females did not include menstrual cycle period topics with exact talk of when the period started and stopped. Mostly, we just handled the logistics of living with ones period without too much fanfare as I recall, but then periods were relatively easy for me compared with what some women experience if I am to believe the drama they often talk about related to periods. I do recall learning from the school nurse that regular bathing and showering as well as timely changing of feminine napkins were recommended just so one didn't start to stink. I most normally try to avoid stinking and prefer not to continue hanging out with those who do!

My daughter and I didn't sync all that closely when I was having a period. Mine was always rather unpredictable so that was probably what messed it up.

May or May not be true, but I know that me and my daughter often have our periods at the same time..

This has to be one of the silliest threads I've seen on Zity. Who cares? What difference does it make? I suppose if one were a Madame running a whorehouse, and all the girls' periods synchronized, it would make for a week of bad business, LOL!

I don't know anything about synchronized periods although I think someone (probably Susie) said that this is another urban myth and that some periods will start at the same time just by chance. I do know with guys however when we all drink beer at the same time we tend to synchronize burping and farting so there may be something to it after all.

When my daughters were all home they did occasionally sync up maybe four or five times a year, it was always a nightmare.

And Moppy, men don't need beer to burp or fart, you all are natural gas factories. Just sayin..😏

My wife her 3 sisters and mother all started with in a day or 2 of each other when one started they all knew they were going to start any day.
