A new study has raised the alarm for night owls, indicating those who wake up and go to bed Later they may face a higher risk of developing type 2 diabetes and heart disease.
Research by scientists in the US found that early risers tend to be healthier than those with more nighttime habits, even when both groups practiced the same thing.
Differences in metabolism, particularly in how the body handles fat, is thought to be behind the difference between early temporal patterns (people who rise early) and late temporal models (those who rise early). sleep late).
“These findings suggest that early temporal patterns have differences in fuel selection that are associated with type 2 diabetes risk,” the researchers wrote in the study, published in the journal. Experimental physiology on Monday.
The findings may be particularly relevant in the Middle East, where many people reach out late at night and nap during the day.
Early bird benefits
The central finding of the study, which was based on an analysis of 51 participants, was that the bodies of early risers tended to consume more fat at rest and during exercise, even when both groups had the same level of fitness.
Additionally, early risers were more physically active throughout the day, something that is likely to contribute to better health outcomes.
The researchers, from Rutgers University and the University of Virginia, found that late risers were more sensitive to insulin. This means their cells need more insulin, something the scientists said was caused by differences in activity levels.
This could be linked to an increased risk of type 2 diabetes, which is a major problem in the UAE and other parts of the Gulf region.
Experts have suggested eating later in the day and feeling less light in the morning and more darkness in the evening as possible reasons why late sleepers are more susceptible to insulin sensitivity.
While the latest study points to the benefits of getting up early, Dr Chen Song, a lecturer in neuroscience at Cardiff University in the UK who researches sleep, said it was not generally known whether it was better to be an early temporal or a late temporal pattern.
One reason a person’s sleep pattern affects their well-being, she said, is a mismatch between several factors, including physiological and cognitive (brain) influences, that affect how a person sleeps.
“This may be due to habits they developed during childhood, when they were forced to sleep early or later, which could affect habits later in life,” she said.
Genes influence a person’s sleep pattern, which is strongly influenced by melatonin. This is a hormone secreted by the pineal gland, a pea-shaped structure in the brain.
Melatonin is sometimes called the dark hormone, because it is released in response to low levels of light and acts on receptors in the body to induce people to sleep.
In early birds, melatonin is released earlier. This makes these people go to bed, get up early and be more active in the morning.
By contrast, it is released later in night owls, who tend to stay up late and struggle with early starts. They are also said to be more likely to consume alcohol and caffeine and have higher amounts of fat around the stomach and abdomen.
British study raises concerns for late beginners
The new research isn’t the first to suggest that night owls can have negative health effects.
A study published last year that used data from wrist activity monitors worn by more than 85,000 people in the UK, found that among those who stayed up late, they were more likely to report anxiety or depression.
Speaking when the study was released, Dr. Kristin Knutson, assistant professor and specialist in sleep medicine at Northwestern University School of Medicine at Northwestern University Feinberg in the US, said the health issues associated with being a chronotype retarded person “were likely a result of being A night owl living in the morning world.” This can disrupt the body’s circadian or circadian rhythms, she said.
To highlight the importance of not disrupting a person’s natural sleep patterns, the American Academy of Pediatrics urged middle and high schools in the United States to consider introducing later start times.
Starting later, the organization said in a 2014 research paper published in the journal PediatricsIt correlates best with the body clocks of teens, who typically need between eight and a half to nine and a half hours each day.
