A study conducted by Imperial College London indicates that night owls—individuals who stay up late and wake up late—may possess superior cognitive function compared to early risers. This finding contrasts with traditional beliefs that often associate morningness with better performance. The research surveyed approximately 26,000 individuals in the UK, categorizing them based on their sleep patterns or 'chronotypes.'

Azizi Seixas, Associate Director at the Center for Translational Sleep and Circadian Sciences at the University of Miami, explained that the study found those who identified as night owls or intermediate on the spectrum between morning and evening types demonstrated better cognitive skills. This challenges previous assumptions that morning people perform best academically and cognitively.
Seixas noted that while night owls may excel in cognitive tests, they also face increased health risks. Morning individuals have shown lower rates of conditions such as cardiovascular disease, diabetes, and high blood pressure, while night owls could be at greater risk for heart issues.
Furthermore, Seixas emphasized the importance of aligning daily activities with one's natural chronotype for optimal performance. He advised that individuals should establish a consistent sleep schedule and aim for seven to nine hours of sleep each night to maximize health benefits.
To improve sleep quality, Seixas highlighted the importance of reducing pre-bedtime stress, avoiding heavy meals right before sleeping, minimizing exposure to blue light from devices, and creating an environment conducive to sleep.
