Night Owls Exhibit Superior Cognitive Function in Recent Studies, Challenging Traditional Sleep Wisdom

London, UK – Emerging research is challenging the long-held belief that early risers possess inherent advantages, with recent studies suggesting that individuals who habitually go to bed late, often termed "night owls," may exhibit superior cognitive function. This finding, highlighted by medical professionals like Nicholas Fabiano, MD, points to a complex relationship between sleep patterns and intelligence. A significant study conducted at Imperial College London, analyzing data from over 26,000 participants in the UK Biobank, revealed that night owls and those with intermediate sleep patterns scored higher on cognitive tests measuring intelligence, reasoning, reaction time, and memory compared to early risers. Dr. Raha West, lead author and clinical research fellow at Imperial College London, emphasized the importance of sleep duration, stating, "While understanding and working with your natural sleep tendencies is essential, it’s equally important to remember to get just enough sleep, not too long or too short." While some earlier research, like a 2017 study by Satoshi Kanazawa, psychologist at the London School Of Economics And Political Science, also suggested a link between later sleep times and higher IQ, the underlying reasons remain a subject of ongoing scientific inquiry. A study comparing Mensa members (individuals with IQ ≥ 130) with a control group found that while Mensa members did exhibit later sleep timing on workdays, this was primarily attributed to later work schedules rather than a biological predisposition to being a night owl. The study concluded that "later sleep timing in those with higher IQs is not due to physiological differences, but rather due to later work schedules." Despite potential cognitive advantages, research also indicates possible health trade-offs for night owls. Studies have suggested that evening chronotypes might face a higher risk of metabolic issues, including elevated BMI and cholesterol, and increased cardiovascular mortality. Conversely, early risers often demonstrate better overall health outcomes. Neurologist Clifford Segil and Dr. West agree that maintaining adequate, high-quality sleep—typically seven to nine hours—is paramount for brain health, irrespective of one's chronotype.
