It's Not Just The Mornings: Night Owls Face a Hidden Cost at Work, Finnish Study Suggests - ScienceAlert

It is 11 pm, and your brain has finally decided to cooperate. The task that felt impossible all afternoon suddenly seems manageable. You want to read, finish something, or follow an idea. Then the morning alarm rings. That energy has vanished, but the working day is starting anyway. For night owls, this clash can feel familiar. A Finnish study suggests their difficulties may extend beyond mornings: evening types were more likely to receive a disability pension years before the usual retirement age. Researchers followed 5,679 adults for 12 years. Before adjusting for other factors, evening types had an approximately 70 percent higher rate of receiving a disability pension than morning types, accounting for when pensions were awarded. The finding appeared in both men and women, and persisted after accounting for socioeconomic factors, including education and income. But health emerged as an important part of the explanation.
