The chart below shows the sleep patterns of people in five different occupations according to a Canadian study.
The chart presents a research resulted by a Canadian providing the data about the sleep patterns of people in five different professions. Overall, both students and business executives have normal on their sleep schedule, while truck drivers, full-time mothers and doctors sleep in interrupted hours.
As the provided data, it can be seen that students and businesses executives have sleep time continuously from 11 p.m. to 7 a.m., but business executives have to get up two hours earlier than students. It means that they only spend their time only 6 hours for bedtime which is one hour more than the doctor's sleep schedule.
On the other hand, truck drivers have discontinuous sleep schedule and spend 6 hours for sleeping about 3 hours in each morning and afternoon. In the following, there are full-time mothers having 8-hours sleeping time, with 2 hours in the afternoon for taking a nap due to getting up in the early morning, 3 a.m. Another case, doctors are the busiest jobs in this data because they only have 5 hours for sleeping in the early morning 1 a.m., but they have to wake up and do their duties again at 3 a.m.
