It turns out that staying up late could be good for our brain power as research suggests that people who identify as night owls could be sharper than those who go to bed early.

Researchers found that those who stay up late had “superior cognitive function” while morning larks had the lowest scores in intelligence, reasoning, reaction time and memory tests.

The study, published in BMJ Public Health, found that sleeping between seven to nine hours a night was optimum for brain function.

By contrast, sleeping for fewer than seven hours or more than nine hours had a marked detrimental effect on brain function.
