Today, Friday, Feb. 3, marks National Wear Red Day, a day when the eye-catching color can be used to increase awareness of heart disease in women. This year’s celebration marks 15 years of the designated day, which signifies the fight against heart disease as the No. 1 killer in women. According to Mayo Clinic, many forms of heart disease can be prevented or treated with healthy lifestyle choices. In addition, knowing heart disease symptoms and when to seek emergency medical care can save lives, which is something everyone can advocate.
