![]() ![]() ![]() Your personal sleep chronotype, which is thought to be inherited, may determine when that process occurs. Staying up later can go hand and hand with alcohol and other vices that can affect both sleep and health, experts say. “Other possible causes that come to mind include those who are evening types will likely need to wake up early for work/school therefore end up getting less sleep and the sleep deprivation can increase risk,” 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. However, a 9% increased risk of early death is significant, he added, leaving room for other ways being an evening type could increase the risk of mortality. Bhanu Prakash Kolla, a sleep medicine specialist in the Center for Sleep Medicine at the Mayo Clinic in Rochester, Minnesota, who was not involved in the study. “We have known for a long time that those who have an evening type preference are more likely to be heavier drinkers, have alcohol use disorder and are also more likely to use other substances including tobacco,” said Dr. After adjusting the data to account for educational level, use of alcohol, smoking, the level of body mass, and sleep duration, the study found that being a night owl increased the risk of an early death by about 9% compared with morning types, who are often called early birds. Over 29% were clearly morning people, while another 27.7% described themselves as somewhat inclined to prefer mornings.įor the new study, researchers looked at death records of a subset (8,728 participants) of the original study. Only about 10% of the twins described themselves as definite evening people, while 33% said they somewhat preferred staying up late. When the study originally began, each twin was asked to pick one answer from the following questions: I am clearly a morning person I am to some extent a morning person I am clearly an evening person or I am to some extent an evening person. The new study followed nearly 24,000 twins from 1981 to 2018 in an effort to tease out the causes of health-related behaviors and disease. The study, published Friday in the journal Chronobiology International, was a follow-up to the 2002 Finnish Twin Cohort study. This is compared to those who are clearly ‘morning’ persons,” said study first author Christer Hublin, a researcher from the Finnish Institute of Occupational Health in Helsinki, in a statement. ![]() “The increased risk of mortality associated with being a clearly ‘evening’ person appears to be mainly accounted for by a larger consumption of tobacco and alcohol. 8 reasons why you wake up tired, and how to fix it ![]()
