Most replayed moment: Why sleep may be the key to heart health | Dr Nour Makarem

Sleep health serves as a critical foundation for cardiovascular well-being, with poor sleep quality significantly increasing the risk of heart disease and stroke. Dr. Nour Makarem identifies high blood pressure as the primary driver of heart disease and emphasizes that sleep health extends beyond the absence of disorders. A key insight is the importance of sleep regularity; maintaining consistent bed and wake times within a 30-to-60-minute window is essential for heart protection. Irregular sleep patterns can double cardiovascular risk, rivaling the impact of smoking or obesity. Optimal health requires seven to eight hours of sleep, as both insufficient and excessive sleep durations correlate with increased disease risk. Practical habits, such as consistent scheduling, daytime physical activity, and limiting stimulants, are vital for maintaining long-term cardiovascular health.
