Cardiovascular health involves more than the heart itself. Your arteries, veins, blood pressure, cholesterol, triglycerides, circulation, sleep, diet, physical activity, and metabolic health all influence how well your cardiovascular system functions over time.
This section brings together our evidence-informed guides to heart health, blood pressure, circulation, cholesterol, triglycerides, vascular health, nutrition, exercise, and supportive natural approaches. If you are new to the subject, start with our guide to cardiovascular and pulmonary disease for an overview of how the heart, blood vessels, and lungs work together.
Explore Cardiovascular Health
Different cardiovascular problems call for different approaches. Use the topics below to find the information most relevant to you.
- Blood Pressure: High blood pressure often develops without obvious symptoms, which makes accurate measurement especially important. Explore our Blood Pressure resource center, learn how to monitor blood pressure at home, understand the morning blood pressure surge, and see what the evidence says about exercise for blood pressure and the connection between sleep and blood pressure.
- Cholesterol, Triglycerides & Artery Health: Blood lipids are an important part of cardiovascular risk, but cholesterol and triglycerides are not the same thing. Learn how to lower triglycerides naturally, what to know about a cholesterol test at home, which foods support healthy arteries, and how to build a practical heart-healthy diet.
- Circulation & Nitric Oxide: Healthy blood vessels need to be able to relax and respond to changing demands for blood flow. Nitric oxide is one of the signaling molecules involved in that process. Our guides explain natural ways to support nitric oxide and how nitric oxide relates to blood pressure without treating supplements as a substitute for medical care.
- Heart-Healthy Food & Lifestyle: Cardiovascular protection is usually built from several small habits rather than one food, herb, or supplement. Start with our 23 heart-healthy foods and our evidence-based look at natural approaches to high blood pressure. Regular physical activity, a nutrient-rich diet, healthy sleep, avoiding tobacco, and managing blood pressure, blood sugar, cholesterol, and triglycerides all contribute to long-term cardiovascular health.
What Does Cardiovascular Health Include?
The cardiovascular system consists primarily of the heart and the network of blood vessels that carry blood throughout the body. Cardiovascular disease is a broad term that can include coronary artery disease, heart failure, abnormal heart rhythms, stroke, peripheral vascular disease, and other disorders involving the heart or blood vessels.
Many of the factors that affect cardiovascular risk are connected. High blood pressure can gradually damage blood vessels. Elevated LDL cholesterol can contribute to plaque formation within artery walls. High triglycerides often occur alongside other metabolic risk factors. Poor sleep, smoking, physical inactivity, diabetes, and excess body weight can add additional strain.
That is why cardiovascular health is best approached as a system rather than as a search for one “heart-healthy” ingredient.
Supporting Your Heart and Blood Vessels
For most people, the strongest foundation is straightforward: eat mostly minimally processed foods, include plenty of vegetables, fruit, legumes, whole grains, nuts, seeds, and other fiber-rich foods, choose healthier sources of fat, stay physically active, get adequate sleep, avoid smoking, and keep track of important measurements such as blood pressure and blood lipids.
Natural approaches can sometimes complement these basics, but “natural” does not automatically mean safe or effective. Herbs and supplements can cause side effects, interact with prescription medicines, or lower blood pressure more than intended when combined with medication. Our cardiovascular guides therefore focus not only on what may help, but also on the strength of the evidence and important safety considerations.
Know Your Numbers
Blood pressure, LDL and HDL cholesterol, triglycerides, blood glucose, and other measurements can reveal cardiovascular risk long before symptoms develop. Home monitoring can be useful, but isolated readings are rarely as informative as properly measured trends interpreted alongside your overall health and medical history.
If you already have high blood pressure, high cholesterol, diabetes, heart disease, or another cardiovascular condition, work with your healthcare professional rather than stopping or replacing prescribed treatment based on information found online.
When Cardiovascular Symptoms Need Medical Attention
Do not try to manage potentially serious cardiovascular symptoms with diet, herbs, supplements, or home remedies alone. Severe or persistent chest pain or pressure, sudden severe shortness of breath, fainting, or possible stroke symptoms such as facial drooping, arm weakness, or difficulty speaking require immediate medical attention.
