‘Man, this is a tough one’: Cardiologist shares simple rules for a healthier heart

In a recent Instagram video, board-certified cardiovascular surgeon Dr. Jeremy London explained the essential habits for maintaining long-term cardiovascular health. During a rapid-fire "this or that" challenge, he compared red wine and CoQ10, ultimately favoring CoQ10. He emphasized that while red wine contains beneficial polyphenols, the quantity required to reap those benefits would be harmful to overall health. He also highlighted that daily brushing and flossing were more impactful on cardiovascular health than CoQ10.

When asked to choose between oral hygiene and rucking, a fitness trend involving walking with a weighted vest, London admitted that rucking was more important due to its cardiovascular benefits. He praised daily fibre intake for regulating glucose levels and supporting the microbiome, but it still came second to exercise. When rucking was compared to sleep, his response was clear: "Man, sleep is king. If your sleep isn’t good, all the other things really suffer. So sleep has to win for me."

Dr. CM Nagesh, Founder of Cardea Super Speciality Hospital, shared that the connection between oral health, sleep quality, exercise, and cardiovascular disease risk is stronger than most people realize. Poor oral health, especially untreated gum disease, is linked to chronic inflammation, a known contributor to cardiovascular disease.

Poor sleep quality has been associated with hypertension, arrhythmias, and increased cardiac stress. Physical inactivity compounds these risks by affecting metabolism, vascular health, and weight regulation. While supplements like CoQ10 may provide supportive value in specific cases, they should never replace fundamental lifestyle habits such as regular physical activity, quality sleep, balanced nutrition, smoking cessation, and stress management. According to Dr. Nagesh, the greatest cardiovascular protection still comes from these core habits.
