National Wear Red Day, held on the first Friday in February each year, is a day when Americans nationwide wear red to show their support for women's heart disease awareness.
The Heart Truth—is a national awareness campaign for women about heart disease sponsored by the National Heart, Lung, and Blood Institute, part of the National Institutes of Health, U.S. Department of Health and Human Services. Designed to warn women of their #1 health threat, The Heart Truth created and introduced the Red Dress as the national symbol for women and heart disease awareness in 2002 to deliver an urgent wakeup call to American women. The Red Dress reminds women of the need to protect their heart health, and inspires them to take action. National Wear Red Day provides an opportunity for everyone to unite in the national movement to raise awareness of the #1 killer of American women--heart disease--by showing off a favorite red dress, shirt, or tie, or the Red Dress Pin.
