Heart Health: Ten Habits That Harm Your Heart Without You Realizing It

Cardiologist Nicolas Girerd highlights ten habits that harm heart health, often without us realizing it. Insufficient sleep, stress, excessive salt and alcohol consumption, a sedentary lifestyle, and lack of regular exercise are some of the factors negatively impacting the cardiovascular system. Professor Girerd explains the mechanisms through which these habits cause damage, such as activation of the sympathetic nervous system, metabolic disruption, and chronic inflammation. The American Heart Association recommends at least seven hours of sleep per night to maintain cardiovascular health.
