...there are no “late-riser” special discounts or idioms such as “the night owl catches the worm.” That's because of societal pressures, says Prof. Peigneux, co-author of the study. Those who hit their stride at midnight are often required to then get up early for work or school. They may appear to be lazy or unmotivated – but are really just sleep-deprived.
“If you allow them to live on their preferred schedule, then they can outperform the morning types,” he said.
The study measured the part of the brain that is home to the circadian master clock that operates according to a day-night cycle. Sleep pressure dampens the circadian signal, and activity in this area decreases the longer the person is awake. The night owls were more resistant to sleep pressure.
