The past year of quarantine has led to insomnia and sleeplessness for many. A 2020 study of pandemic data from China and Italy found high rates of sleep disruption in the general population throughout the crisis, from acute insomnia to poor sleep hygiene (too much screen time before bed, for example). That can do more than drag us down; it can directly relate to cardiovascular disease, says Brooke Aggarwal, assistant professor of medical sciences in the cardiology division of the Vagelos College of Physicians and Surgeons at Columbia University.
