Researchers argued that based on those results, 20 could be considered “the first biological marker of the end of adolescence”. There was also a gender split recorded, with males participants being on average, later chronotypes for most of their adulthood, but reaching the peak of their lateness at an older age than the females (19 and a half, compared to 21 for females). That difference disappeared around the age of 50.

There are potential issues to consider, though. The paper acknowledges that “Our data also cannot formally rule out behavioural and environmental factors influencing the age- and sex-dependent differences in chronotype; i.e. do teenagers sleep late because they go to the disco or do they go to the disco because they cannot sleep until late?”
