Cardiovascular health is one of the strongest indicators of overall wellbeing. Most people believe that heart issues stem mainly from poor diet, lack of exercise, or high blood pressure. However, Russian cardiologist Dr Dmitry Yaranov who specializes in heart failure, transplantation, and mechanical circulatory support recently revealed that there’s much more to heart health than what meets the eye.

In an Instagram post shared on November 4, Dr Yaranov highlighted six surprising factors that can significantly harm your heart. He noted, “After treating thousands of patients with heart failure, these are the things I wish more people knew before it was too late.” According to him, cardiovascular wellness isn’t just about numbers it’s about lifestyle foundations like sleep, stress, air quality, and even gut health.

1. Sleeping Only 6 Hours a Night

If you’re sleeping less than 7 hours a night in the name of productivity, it might be time to rethink your priorities. Dr Yaranov warns that chronic sleep deprivation increases the risk of heart failure, stroke, and sudden cardiac death. Rest is essential for heart recovery and hormonal balance.

2. Air Pollution

Living or commuting in areas with heavy traffic or industrial emissions exposes you to toxic pollutants. The cardiologist explains that air pollution can harden arteries, increasing the likelihood of heart failure and other cardiovascular diseases. Breathing clean air, whenever possible, is vital for long-term heart health.

3. Stress

While stress may seem like a normal part of modern life, Dr Yaranov emphasizes that constant stress leads to cortisol overload, which causes high blood pressure and inflammation. Over time, this weakens the heart and blood vessels. Managing stress through mindfulness, physical activity, or hobbies can make a world of difference.

4. Avoiding Dental Check-Ups

Neglecting oral hygiene can have serious effects beyond cavities and bad breath. According to Dr Yaranov, gum disease triggers systemic inflammation, which may raise the risk of heart attacks. Regular dental check-ups can help reduce inflammation and protect heart health.

5. Lack of Nutritional Food

Even if someone wants to eat healthy, a lack of access to nutritious foods often seen in “food deserts” can lead to worse cardiac outcomes. The cardiologist notes that maintaining a diet rich in fruits, vegetables, and whole grains supports heart function and overall health.

6. Ignoring Gut Health

Dr Yaranov highlights the connection between the gut microbiome and the cardiovascular system. “Your microbiome helps regulate blood pressure and cholesterol. Feed it right,” he advises. Consuming fiber-rich foods, probiotics, and staying hydrated can improve gut balance and, in turn, protect your heart.

Final Takeaway

Heart health is far more complex than exercise and diet alone. As Dr Yaranov reminds, it’s about holistic wellbeing how you live, breathe, sleep, eat, and even think. Small daily changes in these areas can lead to a stronger, healthier heart.
