11/3/2023 0 Comments Night owl reading light“When chronotype was not matched with work hours we saw an increase in type 2 diabetes risk,” said coauthor Tianyi Huang, an assistant professor of medicine at Harvard Medical School and Associate Epidemiologist of medicine at Brigham and Women’s Hospital, in a statement. Just 2 minutes of walking after eating can help blood sugar, study says While researchers found significant associations between developing diabetes in night owls who worked during the day, they did not find an association for night owls who went to work later in the day or worked overnight shifts. That data was then correlated to medical records to determine who developed diabetes. ![]() The study collected data from 2009 to 2017, including self-reported chronotype, diet quality, weight and BMI, sleep timing, smoking behaviors, alcohol use, physical activity and family history of diabetes. The study, published Monday in the journal Annals of Internal Medicine, followed nearly 64,000 nurses participating in the Nurses’ Health Study II, one of the largest investigations into the risk factors for major chronic diseases in women. “We get a sort of domino effect, which can increase our risk of having diabetes, cardiovascular disease and other chronic illnesses.”Įarly birds tend to perform better in school and are more active throughout the day, which may partly explain why studies have found they have less risk of cardiovascular disease, experts say. “Secretion of hormones can change because of staying up late, our body’s temperature regulation can change, and metabolism can change in a negative way,” Kianersi said. When sleep disrupts those rhythms, the body is out of sync. Every cell in the body has its own circadian rhythm - including when you feel hungry, when you void your bowels, when you feel energetic enough to exercise and how well your immune system works. How to sleep in a heat wave, according to expertsīut that’s not all. In night owls, however, the internal body clock secretes melatonin much later, making early mornings sluggish and pushing peak activity and alertness later into the afternoon and evening.Įlectric fan in-front of an unmade bed with light coming through a window brazzo/iStockphoto/Getty Images If you’re an innate early bird, your circadian rhythm releases melatonin much earlier than the norm, energizing you to become most active in the morning. ![]() Personal sleep chronotypes are thought to be inherited however, with some work, they can be changed. ![]() “The main takeaway is that people who have a clear evening preference should be aware of these risks, moderate their alcohol use, eliminate smoking, increase physical activity and get more sleep and manage some of these risks as best as they can,” Kolla said in an email.Įveryone has an internal 24-hour body clock, or circadian rhythm, that regulates the release of the hormone melatonin to promote sleep. Bhanu Prakash Kolla, a sleep medicine specialist in the Center for Sleep Medicine at the Mayo Clinic in Rochester, Minnesota. “Even after accounting for all lifestyle factors, there is a slight increased risk of diabetes, suggesting that there could be some genetic predisposition accounting for both the diabetes and the evening preference or potentially other factors that have not been accounted for,” said Dr. When Kianersi and his team factored the unhealthy habits out of the data, the risk of a night owl developing type 2 diabetes dropped to 19% compared with early birds, or people who like to get up and go to bed early.īeing a night owl can contribute to poor sleeping habits as well as other unhealthy habits, experts say. “Night owls overall were more likely to have a poor diet, to be less physically active, to use alcohol in higher quantities, to have an unhealthy BMI (body mass index), to smoke and to sleep less or more than the seven to nine hours that’s recommended each night,” Kianersi said. Researchers also found strong connections between a “late-to-bed-and-rise” sleep style and some unhealthy behaviors - all known contributors to chronic diseases such as type 2 diabetes. “When we looked at the relationship between chronotype and diabetes we found night owls had a 72% increased risk of developing diabetes over the eight years of our study,” said lead author Sina Kianersi, a postdoctoral research fellow at Brigham and Women’s Hospital and Harvard Medical School in Boston. ![]() If so, you could be at higher risk of developing type 2 diabetes as well as a number of unhealthy lifestyle habits, a new study found.
