The table delineates the sleep patterns of individuals engaged in five distinct occupations, as documented in a Canadian study.
Overall, the data reveals significant variations in sleep duration and patterns among the occupational groups, with students exhibiting the most prolonged sleep duration and doctors obtaining the least sleep.
Students typically experience uninterrupted slumber from midnight until 4 a.m., followed by a few hours of wakefulness before resuming sleep from noon to 1 p.m. This results in a total of approximately 8 hours of sleep. Conversely, truck drivers display a more fragmented sleep pattern, initially sleeping from midnight to 3 a.m. and then resting again from 8 p.m. to 1 p.m. the following day, accumulating around 7 hours of sleep. In contrast, full-time mothers manage a consistent sleep span from 11 p.m. to 5 a.m., along with a short afternoon rest, which also totals about 6 hours of sleep.
Business executives typically retire to bed by 9 p.m. and rise at 4 a.m., making for a total of 7 hours of sleep, mirroring the truck drivers’ overall sleep duration. Finally, doctors, who have irregular work hours, sleep from 9 p.m. to 3 a.m. and again from noon to 1 p.m., leading to a total of only 5 hours of sleep – the least among the examined groups. The discrepancies in sleep patterns can likely be attributed to the demands of their respective professions, with higher responsibility roles such as that of a doctor contributing to reduced rest periods.
