The study, published in the Public Library of Science (PLOS) Medicine journal, looked at the health and sleep of UK civil servants.All 8,000 participants were asked about how much sleep they got each night.

Some people even wore watches with sleep trackers on their wrists.They were then asked about serious diseases and disorders such as diabetes, cancer and heart disease during the past two decades.

People who were about 50 years old and slept five hours or less had a 30 percent higher risk of many diseases than those who slept seven hours.Less sleep at age 50 was also associated with a higher risk of death, primarily due to an increased risk of serious illnesses.
