A new study finds that people with prediabetes who prefer evening activities and go to bed late have higher chances to gain weight than early risers with the same condition.
A team of researchers from the University of Illinois at Chicago College of Medicine examined 2,133 people with prediabetes aged 64 years on average. Scientists assessed their preferences for going to bed late and waking up early, respectively.
Dr. Sirimon Reutrakul, an associate professor of endocrinology, diabetes, and metabolism, says: “Timing and duration of sleep are potentially modifiable […] People can have more regular bedtimes and aim to have more sleep, which may help reduce BMI and the potential development of diabetes in this high-risk group.”
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.
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.”
