“Night Owls” May Have Higher Chances of Early Death

A new study that included about one million people in Britain finds that people who wake up late, so-called night owls, have 10% higher risk of dying sooner than people who rise and set with the sun.night owls

For the study, the scientists have analyzed information on more than 430,000 people aged from 38 to 73 from a public database, who defined themselves as “definitely a morning person” (27%), “more a morning person than evening person” (35%), “more an evening person than a morning person” (28%), or “definitely an evening person” (9%).

One of the authors of the study Kristen Knutson of Northwestern University in Chicago says: “The higher risk may be because people who up late have an internal biological clock that doesn’t match their external environment. It could be psychological stress, eating at the wrong time for the body, not exercising enough, not sleeping enough, being awake at night by yourself, maybe drug or alcohol use.”
