Studies have revealed night owls may take more risks and are more likely to skip breakfast and eat more later in the day. Night owls were also more likely to be insulin-resistant, meaning their muscles required more insulin to be able to get the energy they need, the study showed. A 2022 study found night owls were more sedentary, had lower aerobic fitness levels, and burned less fat at rest and while active than early birds. Night owls may be at higher risk for chronic disease, prior research has shown. 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. 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.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. Your personal sleep chronotype, which is thought to be inherited, may determine when that process occurs. Your sleep chronotypeĮveryone has an internal 24-hour body clock, or circadian rhythm, that regulates the release of the hormone melatonin to promote sleep. “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. 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. It’s the opposite of an early bird.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 term night owl refers to someone who goes to bed late and wakes up late. There will also be tours of local corporations and plenty of evening hobnobbing at dinners and “night owl” cocktail parties, according to the event’s agenda.This excerpt is about parties that will occur in the late evening. He is a notorious night owl, someone who needs sleep for only a few hours each evening, but it’s unclear whether that status is related to his use of prescription pain medication. In a statement last week, Woods said he also would seek help for a sleep disorder.The example below is about a golf player who stays awake late. Even though I wish I could be a night owl, my new job is forcing me to be an early bird. When and where is the party?Īrlena: It’s at that dance club and it starts at 11 p.m. In this dialogue, two friends are discussing whether or not to go to a party.Īrlena: Hey! I’m going to a party this weekend. That sounds awful! It’s too bad you aren’t both night owls! Since I work better at night than in the morning, my productivity levels have decreased so much.Ĭhristine: Hmmm. This keeps me awake as well, which means I can’t get up as early as I normally do. Kerry: Well, as you know, I’ve always been an early bird.
