US heart surgeon Dr. Jeremy London, who has performed over 8,000 surgeries, advises avoiding smoking, ultra-processed foods, sedentary lifestyles, loneliness, and chronic stress to protect cardiovascular health.
The WHO reports that cardiovascular disease caused nearly 20 million deaths in 2022, highlighting the importance of simple lifestyle changes over extreme fitness routines.
Dr. London emphasizes that while these habits do not guarantee immunity from heart disease, they significantly improve the body's ability to handle health challenges.
