by ResearchersthinkSleeping at least five hours a night can help reduce health risks in people over 50.research reportPublished in the journal PLoS Medicine. The study tracked the sleep and health of around 8,000 British civil servants, some of whom also wore sleep trackers. During the 20-year follow-up, they developed chronic diseases such as diabetes, cancer and heart disease. People over the age of 50 who slept five hours or less had a 30 percent higher risk of developing disease and were more likely to die from an increased risk of chronic disease than those who slept seven hours. Experts usually recommend seven or eight hours of sleep each night.
