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.”
Some people dream every night, others have dreams from time to time but both categories sometimes have dreams that may completely whack us out. And here are 7 possible reasons for such kind of dreams:
- You ate spicy food before going to bed.
- You are taking melatonin supplements.
- You watched television before bed.
- You’ve recently stopped taking medication.
- You suffer from sleep apnea.
- You did not sleep well enough the night before.
- You are under stress and anxiety for the whole day.
Previously, it was thought that senior people just need less sleep than youth, but a new research has discovered that adults begin losing their ability to lapse into a deep and restorative sleep from about their middle thirties.
For the study, the researchers analyzed the scientific literature published in the medical journal Neuron. The scientists also found that we also start showing signs of aging.
One of the authors of the study Professor Matthew Walker says that it is the lack of sleep also linked to a number of deadly diseases, especially those affecting the brain. He explains: “Sleep changes with aging, but it doesn’t just change with aging; it can also start to explain aging itself.”
A new study, published in the journal Frontiers in Behavioral Neuroscience, discovered that such popular vegetables as onions, leeks, and artichokes help humans to relax and have a better sleep at night. These plants are high in prebiotics and fiber.
For the study, a team of scientists fed 3-week-old male rats a diet of either standard chow or chow with prebiotics. The rats that consumed prebiotics spent more time in rapid-eye-movement sleep.
The researchers from the University of Colorado Boulder that executed the study say: “It is possible that a diet rich in prebiotics started in early life could help improve sleep, support the gut microbiota and promote optimal brain/psychological health.”
A recent study, published in the journal Neurology, suggests that senior people who start sleeping more than 9 hours every night might be at risk of developing dementia.
Having analyzed data of almost 2,500 people, researchers didn’t find any increased risk in people who had been sleeping 9 or more hours a night for more than an average of 13 years. But those who had begun sleeping more than 9 hours recently had the nearly double risk of developing dementia, compared to the counterparts.
Dr. Jiu-Chiuan Chen, an associate professor at the Keck School of Medicine at the University of Southern California, wasn’t involved with the study but said the research seems valid.
