Three studies investigate the relationship between sleep patterns, chronotype, and cognitive performance. The first study, conducted at Imperial College London, analyses data from over 26,000 participants and finds that individuals who identify as "night owls" generally score higher on cognitive tests than those who prefer mornings. The second study, published in BMJ Public Health, explores the relationship between chronotype, sleep quality, physical activity, and dietary intake in a cohort of over 3,000 participants in Istanbul, Turkey. The study finds a strong association between evening chronotypes and poor sleep quality and that physical activity influences sleep quality. Finally, the third study, published in BMJ Public Health, further examines the effect of sleep patterns, chronotype, and health and lifestyle factors on cognitive performance in over 26,000 participants in the UK. This study confirms that individuals with evening chronotypes tend to score higher on cognitive tests than morning types and identifies a complex relationship between sleep patterns, health factors, and cognitive function.
