Cardiothoracic Surgeon Identifies 5 Daily Habits Linked to Increased Longevity

A board-certified cardiothoracic surgeon says incorporating five daily habits – exercise, a mindful diet, rest and recovery, meaningful relationships, and sauna/heat therapy – can demonstrably increase lifespan and improve overall health.

Dr. Jeremy London, MD, with over 25 years of clinical experience, outlined the habits in a social media post yesterday, November 4, 2025. He emphasized that exercise is the most impactful, specifically a combination of strength and aerobic training. “Be mindful about what you put in your mouth: protein, fibre, complex carbohydrates, and healthy fats. This is truly the information that you give every cell in your body,” Dr. London stated regarding the importance of diet.

Beyond physical health, Dr. London highlighted the crucial role of social connection and mental wellbeing. He stressed the importance of surrounding oneself with supportive relationships, quoting Arthur Brooks: “Real friends, not deal friends.” He also advocated for prioritizing rest and recovery, noting that “sleep is king,” and incorporating dedicated downtime. Furthermore, he suggested sauna and heat therapy, stating that following a prescribed protocol can “decrease your cardiovascular risk, all-cause mortality, as well as your risk of Alzheimer’s and dementia.” Maintaining good cardiovascular health is a key factor in preventing heart disease, the leading cause of death globally according to the World Health Organization.

These findings underscore the growing body of research demonstrating the interconnectedness of lifestyle factors and long-term health. Experts at the Mayo Clinic also emphasize the importance of these holistic approaches to wellness.

Medical professionals recommend consulting with a healthcare provider before making significant changes to diet or exercise routines.
