Band 5+: The chart below shows the sleep patterns of people in five different occupations according to a Canadian study. Write a report for a university lecturer, describing the information below. Give possible reasons for the differences. You should write at least 150 words.

The following table gives information on a group of inhabitants in the five various careers including students, truck drivers, full-time mothers, business executives and doctors who spent their time in dormancy according to a Canadian research.

Overall, it is clear that undergraduates and directors working in a business environment recorded an opportunity to have uninterrupted sleep, while lorry drivers, homemakers or medical practitioners disrupted their sleep patterns due to the nature of their job, especially doctors.

On the one hand, students who are in the age of “study- eat- and sleep” had continuous sleep from 11p.m. to 7a.m. It is understandable because this circadian rhythm, or in other words, it is called “a regular sleep-wake cycle” is needed for the growth of an unmatured child. Besides, the business executive pattern also reported consistent sleep happened between 11p.m and 5a.m. Office-based employment is one of the main factors contributing to sleep schedules being shaped around standard working hours for this subject.

On the other hand, owing to the nature of the work, the majority of drivers, stay-at-home mothers or doctors have to suffer from sleep deprivation. The frequent rotation of work shifts, which is a notable commonplace in the freight transport sector, might lead to an impact on sleeping time. Particularly, they divide their sleep into three stages: first is from 6p.m. to 7p.m., second is from 7a.m. to 10a.m. and from 4a.m. to 6p.m.. Notably, the length of sleep is just about two hours which is very short. Following this, full-time mothers also strive to fall asleep consistently every day. Their sleeping time fluctuates and often falls late at night until 10p.m. to 1a.m. and then wakes up. Time frames from 3a.m. to 6a.m. are also recorded in this group. Most harshly, surgeons noted the shortest sleep circuit among other patterns. 1a.m. to 2a.m., and 4a.m. to 7a.m. are the little time of sleep a doctor can have to recharge their batteries. Burning the midnight oil in the operations possibly affects their sleep quality.
