What Are the Best Lifestyle Tips and Supplements for Heart Health?
September is Heart Awareness Month, a perfect time to focus on one of the most vital organs in our body – the heart!Why is heart health so important?
Your heart beats about 100,000 times a day, pumping roughly 7,500 litres of blood, serving as the body’s central pump, circulating blood and its essential components to every cell, organ, and tissue. Roughly the size of a clenched fist, the human heart is located slightly left of the chest and is made up of four chambers. These chambers coordinate perfectly to keep blood flowing in one direction. The right side of the heart sends oxygen-poor blood to the lungs, where it picks up oxygen, while the left side pumps oxygen-rich blood through arteries to nourish every organ and tissue [1]. This cycle repeats continuously, ensuring that your brain, muscles, and organs are sustained with oxygen and nutrients. There’s no question about the crucial role this organ plays, your heart powers every part of your body—keeping blood flowing, circulation steady, energy available, temperature regulated, and helping you stay resilient under stress [2]. Yet, despite its incredible design, the heart is vulnerable. Poor lifestyle habits, high blood pressure, cholesterol buildup, diabetes, obesity, smoking, and chronic stress can all take their toll. That’s why September is dedicated to raising awareness: protecting your heart through prevention truly saves lives [3]. Heart disease remains a leading cause of death worldwide. According to the World Health Organization, cardiovascular diseases account for approximately 17.9 million deaths per year, making up 32% of all global deaths in 2022 [4]. In South Africa, heart disease is also a growing concern due to rising rates of hypertension, obesity, and lifestyle-related risk factors. [5]How Can You Support and Protect Your Heart Health?
Heart health, like overall wellbeing, starts with a healthy lifestyle [6]. That means not only daily habits but also routine health checks to monitor blood pressure, cholesterol, and blood sugar. These simple steps can help detect and address problems early, before they become serious.6 Lifestyle Essentials for a Strong Heart:
1. Eat for Your Heart
Choose whole foods rich in fibre, lean proteins, healthy fats, antioxidants, and essential vitamins. Minerals like potassium and magnesium are especially important for keeping blood pressure in check. Limit your salt intake—if you have high blood pressure, aim for less than 1,500 mg of sodium per day. Cut back on processed foods, trans fats, and sugary snacks, and swap them for whole food alternatives. A proven approach is the DASH diet (Dietary Approaches to Stop Hypertension), which is flexible, balanced, and designed to improve heart health while supporting overall wellness [7].2. Move Regularly
Aim for at least 150 minutes of moderate exercise each week. Physical activity strengthens your heart, improves blood circulation, lowers blood pressure and cholesterol, and helps manage weight and blood sugar. It also reduces stress hormones, lowering your overall risk of heart disease.3. Maintain a Healthy Weight
Excess weight—especially around the waist—raises the risk of high blood pressure, high cholesterol, and type 2 diabetes, all of which are major risk factors for heart disease and stroke. Carrying extra weight also forces the heart to work harder and can cause structural changes in the heart muscle. The good news? Even modest weight loss can improve heart function, lower blood pressure, and reduce cardiovascular risks.4. Drink Alcohol in Moderation
Whether moderate drinking benefits the heart is debated, but for most people, it isn’t harmful if done responsibly. Moderation means up to one drink per day for women and up to two for men (335 ml beer, 120 ml wine, or 45 ml spirits). Certain people, especially those with heart failure or rhythm problems, should avoid alcohol completely.5. Manage Stress
Chronic stress raises blood pressure and heart rate through stress hormones like adrenaline, placing extra strain on your heart. Over time, this can contribute to artery damage, plaque buildup, and higher risk of heart disease. To manage stress, prioritise quality sleep, try relaxation techniques like meditation, yoga, or deep breathing, and build a strong support network. Learning to set boundaries, accept what you cannot control, and seeking professional help for persistent stress or anxiety can also make a big difference.6. Quit Smoking or Vaping
Smoking and vaping both damage the heart by raising blood pressure and heart rate, narrowing arteries, and increasing the risk of blood clots. These effects drive atherosclerosis (plaque buildup), the leading cause of heart attacks and strokes. Vaping also stiffens arteries and can raise the risk of heart failure, making it nearly as harmful as traditional smoking. Bonus Tip: Laugh More! Laughter really is medicine for the heart. It lowers stress, reduces harmful stress hormones, boosts mood-enhancing endorphins, and relaxes blood vessels—improving circulation and lowering blood pressure. Studies show laughter can increase blood flow by up to 20%, supporting overall cardiovascular health and reducing long-term risk of heart disease.
