Zurich, Switzerland: Sleep is an important aspect of human life. Deep sleep is especially important for overall health. During this stage of sleep, the mind heals and the rest of the body also gets refreshed afterwards.

According to media reports, recently researchers from ETH Zurich and the University of Zurich have shown that increased deep sleep is particularly beneficial for the cardiovascular system. It causes the left ventricle of the heart to contract and relax, especially during deep sleep.

In addition, deep sleep results in the heart pumping blood more efficiently through the circulatory system. The left ventricle of the heart supplies oxygen-rich blood to most organs and the brain through the arteries.

As the heart contracts while blood is being pumped, the left ventricle contracts and pushes blood out like a wet sponge. The more powerful this process is, the more efficient the blood circulation and the less blood is left in the heart. It increases blood flow which has a positive effect on the cardiovascular system.

A team of cardiologists led by Christian Schmid, senior consultant in cardiology at the University Hospital Zurich, used echocardiography to demonstrate that increased brain waves during deep sleep improve cardiac function.

The aforementioned study was recently published in the ‘European Heart’ journal.
