“We do not know the optimal amount of sleep needed to minimize the risk of heart disease,” but people who get less than seven hours a night or more than nine hours may be more at risk than their peers who fall somewhere in the middle of that range, said lead statement author Dr. Marie St-Onge of Columbia University in New York City, in an email.
