Strava study: 90.6% of women report mood changes, 86.2% report tiredness/fatigue while on period

With this data I can now track which days of the month each female teammate gets bloody. Thanks.

Well duh!

I'd like to know how the participants were selected. If they simply put up a message, "Looking for people to answer survey about period," I'd think the people responding were way more likely to be people severely impacted by their period.

So I think these numbers could be way high due to how it was set up (but haven't taken the time to read it).

Does rojo know they're forced to teach arabic numbers in AMERICAN schools?

In other news, the sun came up today.

OMG! In ten minutes, read my informative thread about why ALL runners should be ingesting dihydrogen monoxide for health and performance reasons.

Science gal's point is interesting. I've personally never had any symptoms (until I got an IUD, then I started getting cramps), and I probably would not participate.

Also, the average age of participants was 38.3. That's a bit odd, as it's close to perimenopausal. That means close to half the women surveyed were in their 40s?

That said, it's nice to see research on this subject.
