It’s a disturbing reality: Heart disease kills more women than all cancers combined. In order to bring attention to that important health issue, the American Heart Association (AHA) asks that you wear a red article of clothing on Friday, Feb. 1.

In addition, the AHA is encouraging health groups and organizations to participate in the “America Goes Red Challenge” between now and Feb. 28. If you’re looking for inspiration for your own event, download their free Getting Started Guide, and watch the video of the National Institutes of Health’s National Wear Red Day Flash Mob held in 2012. If you’re ready to suit up in red apparel, visit the AHA Go Red store, whose profits from sales of everything from t-shirts to ties benefit the mission of AHA.

National Go Red Day challenges women to know their risk for heart disease and use the tools that Go Red For Women provides to take action to reduce their personal risk. The initiative was launched in 2004 after it became apparent that – despite the fact that cardiovascular disease claimed the lives of nearly 500,000 American women each year — women were not paying attention to what was considered an “older man’s disease.”

According to the AHA, since the first National Wear Red Day 10 years ago, tremendous strides have been made in the fight against heart disease in women, including:

• 21% fewer women dying from heart disease
• 23% more women aware that it’s their No. 1 health threat
• Publishing of gender-specific results, established differences in symptoms and responses to medications and women-specific guidelines for prevention and treatment
• Legislation to help end gender disparities

The tools and resources available on the Go Red For Women website can be used to formulate a plan for women of all ages, whether they have been diagnosed with heart disease, are caring for someone with heart disease, or want to reduce the risk getting the disease.
