Even though most women in their childbearing years menstruate every month, chances are still a few things about your period that you didn’t know.
Here are ten facts you likely didn’t know when it comes to your monthly menstrual cycle…
1. Girls Are Getting Their Periods Younger
It seems that where the average menstrual age for girls used to be 13 or 14 years old, girls are getting their periods younger. In 2014, the average American female begins menstruation at age 12, which may be caused by a combination of changing diets, environmental stress, and earlier rates of puberty. However, if you’re like me, I was surprised at age 10 by my period; whereas I had friends who waited until the age of 18 to menstruate for the first time.
Current research suggests numerous reasons why girls are now getting their periods younger. According to a 2012 article in Psychology Today, there may be links between early onset of puberty and inattentive or inconsistent parenting. Lower birth weights, exposure to chemicals like bisphenol-A (BPA), and childhood obesity have also been cited as possible causes, and several studies have found clinically significant relationships between early menstruation and lower socioeconomic status.
