Heart disease remains the leading cause of death in the United States, yet it is also one of the most preventable. Each year, Heart Health Month serves as an essential reminder that cardiovascular health plays a critical role not only in longevity but also in brain health, cognitive function, and healthy aging.
The heart continuously works to deliver oxygen and nutrients throughout the body. When the cardiovascular system is supported, every organ benefits — including the brain.
Why Heart Health Matters
According to the Centers for Disease Control and Prevention (CDC), heart disease accounts for 1 in every 5 deaths in the United States. Many of the conditions that increase risk develop gradually and often without noticeable symptoms, making prevention and early awareness essential.
Key risk factors for heart disease include:
- High blood pressure
- High cholesterol
- Diabetes
- Smoking
- Physical inactivity
- Poor nutrition
- Excess body weight
- Chronic stress
Many of these risk factors are modifiable, meaning that lifestyle changes and routine medical care can significantly reduce risk over time.
The Heart and the Rest of the Body
Heart health does not exist in isolation. The cardiovascular system supports every organ, including the brain, by ensuring steady blood flow and oxygen delivery.
When blood vessels become damaged or blood flow is reduced, the effects extend beyond the heart. Poor cardiovascular health is associated with an increased risk of stroke, cognitive decline, and dementia. Supporting heart health is, therefore, a foundational component of long-term brain health.
Key Strategies for a Healthy Heart
The CDC outlines several evidence-based behaviors that support cardiovascular health across the lifespan.
Move More
Regular physical activity strengthens the heart muscle, improves circulation, and helps manage blood pressure and cholesterol. Adults are encouraged to aim for at least 150 minutes of moderate-intensity physical activity per week, such as brisk walking, cycling, or swimming.
Eat for Heart Health
A heart-healthy eating pattern emphasizes:
- Fruits and vegetables
- Whole grains
- Lean proteins
- Healthy fats, such as those found in fish, nuts, and olive oil
Limiting sodium, added sugars, and saturated fats helps reduce strain on the heart and supports vascular health.
Know Your Numbers
Monitoring key health indicators allows for early identification of risk, including:
- Blood pressure
- Cholesterol levels
- Blood glucose
- Body mass index (BMI)
Routine screenings often detect concerns before symptoms appear.
Quit Smoking
Smoking damages blood vessels, raises blood pressure, and significantly increases the risk of heart disease and stroke. Quitting smoking improves cardiovascular health at any age.
Manage Stress and Sleep
Chronic stress and insufficient sleep contribute to inflammation, hypertension, and metabolic dysfunction. Prioritizing stress management and aiming for 7–9 hours of quality sleep each night supports both heart and brain health.
The Heart–Brain Connection
Growing evidence shows that heart health and brain health are deeply interconnected. The same blood vessels that nourish the heart also supply the brain with oxygen and nutrients. When cardiovascular health is compromised, the brain may also be affected.
Research supported by the National Institute on Aging indicates that conditions such as high blood pressure, high cholesterol, diabetes, and atherosclerosis are associated with an increased risk of cognitive decline and dementia. Reduced blood flow, inflammation, and vascular damage can impair brain function over time, contributing to memory loss and other cognitive changes.
This connection is often summarized by a guiding principle of the Health & Aging Brain Study–Health Disparities (HABS-HD), articulated by our Lead Principal Investigator, Dr. Sid O’Bryant:“What’s good for the heart is good for the brain.”
Managing cardiovascular risk factors through movement, nutrition, smoking cessation, stress reduction, and routine medical care not only protects the heart but may also help preserve cognitive health as we age. In this way, heart health strategies are also brain health strategies.
Heart Health Across the Lifespan
Heart health is not only a concern later in life. Cardiovascular risk can begin developing in young adulthood and even earlier. Establishing healthy habits early helps protect the heart over decades, while making changes later in life still provides meaningful benefits.
For older adults, managing conditions such as hypertension and diabetes becomes especially important. For younger individuals, prevention and awareness lay the foundation for long-term cardiovascular and cognitive health.
Health Equity and Heart Disease
Heart disease does not affect all communities equally. Social determinants of health — including access to nutritious food, safe spaces for physical activity, healthcare access, and chronic stress — play a significant role in cardiovascular outcomes.
Addressing heart health through an equity lens is essential to reducing disparities in both cardiovascular disease and dementia risk. Heart Health Month is an opportunity to reinforce the importance of prevention, education, and access for all communities.
The Bottom Line
Heart Health Month is about more than awareness. It is about action. Protecting your heart supports circulation, reduces strain on the body, and plays a critical role in maintaining brain health over time.
Caring for your heart is an investment in your future — not only for longevity, but for preserving cognitive function, independence, and quality of life as you age.
