A STUDY published in the journal BMJ Public Health has found a link between an individual’s preference for morning or evening activity and their brain function. It reveals that early risers may not be as intellectually sharp as so-called night owls.
Researchers at Imperial College London came to this surprising conclusion after studying data from over 26,000 people who had taken part in intelligence, reasoning and memory tests. Participants self-declared themselves either early risers or night owls, depending on the time of day they felt most alert and productive.
