Increased deep sleep benefits your heart
Stimulating the brain with gentle sounds during deep sleep significantly enhances cardiac function, according to a new study. This discovery could have implications not only for cardiovascular diseases but also for competitive sports, among other areas.
In brief
- Researchers at ETH Zurich and the University Hospital Zurich play ultra-brief tones to stimulate the brain during deep sleep.
- This stimulation improves cardiac output and relaxation of the left ventricle.
- Such technology to improve cardiovascular function could be relevant both in disease treatment and competitive sports.
