Enhanced deep sleep may boost heart health, research shows
Recent research conducted by ETH Zurich and the University of Zurich reveals that deep sleep, in particular, holds immense benefits for the cardiovascular system. The study, led by sleep expert Caroline Lustenberger and heart specialist Christian Schmied, demonstrates that targeted stimulation with brief tones during deep sleep can lead to more vigorous contractions and relaxations of the heart's left ventricle.
This effect results in improved blood pumping efficiency, enhancing the flow of oxygen-rich arterial blood to most organs, extremities, and the brain. The left ventricle functions as a crucial component of the cardiovascular system, supplying oxygenated blood to various parts of the body. When it contracts, it effectively wrings out the blood, increasing circulation and positively affecting heart health.
