National Wear Red Day is an annual awareness event dedicated to heart disease, the leading cause of death in the United States for both men and women. It falls on the first Friday of every February, kicking off American Heart Month. The day is coordinated by the National Heart, Lung, and Blood Institute through its campaign called The Heart Truth, and it’s closely tied to the American Heart Association’s Go Red for Women movement, which launched in 2004.
Why the Focus on Women
Heart disease kills more women each year than all forms of cancer combined, yet for decades it was widely seen as a “man’s disease.” When the Go Red for Women campaign launched in 2004, awareness that heart disease was the number one killer of women was alarmingly low. The campaign grew from a simple awareness effort into an international movement aimed at closing that knowledge gap.
The visibility push has made a measurable difference. Research analyzing internet search trends found that searches for “heart disease in women” spike by an average of 114% each February compared to other months, and searches for “Go Red for Women” itself jump by roughly 494% during the campaign window. That correlation between campaign activity and public interest in women’s heart health is statistically significant, suggesting the red clothing and social media posts translate into people actually looking up information.
Heart disease is the leading killer across most racial and ethnic groups. For Asian American, Pacific Islander, Hispanic, American Indian, and Alaska Native women, it ranks second only to cancer.
Heart Attack Symptoms Women Often Miss
One reason National Wear Red Day emphasizes women is that heart attacks don’t always look the same in women as they do in men. The classic image of someone clutching their chest in severe pain is more typical of men. In women, chest pain or pressure may not be the most prominent symptom at all.
Instead, women more commonly experience sweating, nausea, dizziness, and unusual fatigue. These symptoms can appear while resting or even during sleep, making them easy to dismiss as the flu or simple exhaustion. Shortness of breath, vomiting, back pain, jaw pain, pain in the upper abdomen, and lightheadedness are also common. Because these signs are vague and don’t match the “Hollywood heart attack,” women are more likely to delay seeking help.
How to Participate
The simplest way to mark the day is exactly what the name suggests: wear red. Workplaces, schools, hospitals, and community organizations often coordinate group participation so buildings and social media feeds fill with red on the first Friday in February. Sharing photos with the Go Red for Women hashtag helps amplify the message online.
Beyond the clothing, the day is designed as a prompt to take personal action. That can mean scheduling overdue health screenings, having a conversation with family members about heart disease risk, or donating to heart health organizations. Many local American Heart Association chapters host fundraising walks, educational events, and free screening clinics during Heart Month.
Key Numbers to Know
Part of the campaign’s message is that heart disease is largely preventable when you know and manage a few critical health markers. The American Heart Association’s Go Red for Women initiative recommends tracking these baselines:
- Blood pressure: A reading below 120/80 mm Hg is considered normal for non-pregnant adults.
- Fasting blood sugar: A healthy level is below 100 mg/dL.
- BMI: The recommended range is 18.6 to 24.9.
- Cholesterol: Healthy targets vary by individual, so this one requires a conversation with your doctor about what’s right for your age and risk profile.
These numbers aren’t just abstract lab values. They’re the foundation of what the American Heart Association calls “Life’s Essential 8,” a framework for cardiovascular health built around eight measurable factors: diet quality, physical activity, nicotine exposure, sleep, BMI, blood lipids, blood sugar, and blood pressure. The first four are behaviors you control directly; the last four are health markers influenced by those behaviors and, in some cases, genetics or medication.
The Eight Pillars of Heart Health
The Life’s Essential 8 framework gives a practical roadmap for reducing heart disease risk. On the behavior side, it emphasizes eating a diet rich in fruits, vegetables, whole grains, and lean proteins (modeled after the DASH eating pattern), getting regular moderate or vigorous physical activity each week, avoiding nicotine in any inhaled form, and sleeping an adequate number of hours each night. Sleep was added to the framework relatively recently, reflecting growing evidence that both too little and too much sleep affect cardiovascular risk.
On the health factor side, the framework tracks BMI, cholesterol (specifically non-HDL cholesterol, which captures the harmful types), blood sugar, and blood pressure. Each of these eight components is scored, giving individuals and their doctors a snapshot of overall cardiovascular health rather than focusing on any single number in isolation. The idea is that small improvements across several categories add up to meaningful protection over time.
National Wear Red Day condenses all of this into a single, visible call to action: put on something red, pay attention to your heart, and share the message with someone who might not realize they’re at risk.
