In a time dominated by biohacking trends and longevity supplements California-based cardiologist Dr. Sanjay Bhojraj is bringing the focus back to simplicity. Drawing on more than two decades of experience, he recommends a 15-minute daily walk outdoors as the most effective way to improve health span—the years a person lives in good health.
While many people link cardiovascular fitness to intense workouts, Dr. Bhojraj emphasizes that a short walk offers equally important mental and environmental benefits. In a March 20 Instagram post, he explained that stepping outside and away from the recycled air of offices and hotel rooms helps people reset and reconnect with their surroundings.
Cardiologist Highlights the Power of the ‘Pulse’
Dr. Sanjay Bhojraj said a simple 15-minute walk can make a real difference. It gets people outdoors and into fresh air. It also helps them step away from recycled indoor environments like offices and hotels. He added that these walks help people reconnect with their surroundings and feel the energy around them.
Dr. Bhojraj said the benefits go beyond physical health. He stressed the importance of connection and overall well-being. He explained that walking in a city or nature reduces isolation. It helps people feel part of a larger shared environment.
He also said this habit helps those in high-stress settings. The 15-minute walk acts as a mindfulness practice. It helps ground the nervous system. It also breaks the cycle of prolonged indoor living.

Cardiologist Explains Why a 15-Minute Walk Truly Matters
Although it may sound like wellness advice, science supports Dr. Sanjay Bhojraj’s claim. A 15-minute walk can improve health span.
Research presented at the EuroPRevent Congress 2019 followed over 120,000 people for a decade. It was also published in the British Journal of Sports Medicine. The study found that 15 minutes of brisk walking daily reduced the risk of death by 22%. This was compared to inactive individuals. The findings suggest benefits start well before the 10,000-step goal.
A 2017 study by Chiba University showed similar results. Spending just 15 minutes in nature lowered cortisol by 16%. It also reduced nerve activity and heart rate. These changes help counter stress from indoor lifestyles.
