The Damaging Effects of Sleep Deprivation on Vascular Cells
Chronic mild sleep deprivation can lead to an increased risk of heart disease, according to a study published in Scientific Reports. After just six weeks of shortened sleep, the cells lining blood vessels were found to be flooded with damaging oxidants. Unlike well-rested cells, sleep-restricted cells failed to activate antioxidant responses, resulting in inflammation and dysfunction, which are early indicators of cardiovascular disease. The study provides direct evidence linking sleep deficits to heart health and highlights the importance of getting adequate sleep to reduce cardiovascular risk.
