Have you noticed that in recent years the number of men letting their mustaches grow out in the fall have significantly increased? Well, that isn’t just a coincidence. Movember is a movement that gained traction in the United States and Canada back in 2007, but has since gained global recognition with more than 5.5 million people participating in 2017. But what really is Movember, other than a time of the year where men’s facial hair seems to become all that more common?

Movember is an annual campaign run by the Movember Foundation that takes place during the month of November. Men are challenged to let their mustaches grow out and start a dialogue about men’s health. The idea behind growing out a mustache is that a change in appearance sparks conversation and conversation is what increases awareness. The men’s health issues that Movember aims to raise awareness for are prostate cancer, testicular cancer, and men’s suicide prevention.

The Movember Foundation is the only global charity dedicated solely to promoting awareness and raising money for men’s health issues. The money that has been raised through the Movember campaign has been put towards innovative, breakthrough research and support programs that enable men to live healthier and longer lives.

Looking for a way to get involved and show your support? You’ve got a few options. Grow a ‘stache of your own and spark conversation about men’s health, host a “Mo-ment” for friends, family and coworkers to raise money and talk about men’s health, or start your own Move for Movember campaign and challenge yourself or a group of people to get up and be active in support of men’s health.

So, when you notice an uptick in the number of mustaches you see in November, know that it isn’t just a random coincidence, but it’s actually a show of unity and support for men’s health awareness and disease prevention.
