shift work

Work in a hospital, company, factory (e.g., automobile, petrochemical or textile factory), or other business that is open and operating 24/7 or hours outside of the usual “9 to 5” business hours.

Shift workers suffer increased risk of fatigue-related accidents, and an increased risk of gastrointestinal and cardiovascular disease, infertility, and insomnia; for example, on-the-job fatigue and drowsiness in shift workers was linked to the Challenger space shuttle explosion. SW may be related to an increased in TGs (1.26 mmol/L (112 mg/dL) vs 1.03 mmol/L (91 mg/dL) in normal controls); the cause of this increase is uncertain, but may be related to stress, disturbed circadian rhythm, or the result of night snacking with less efficient removal of TGs. 20% of workers adapt poorly to SW, as it requires abrupt changes in the circadian rhythm; diabetes and epilepsy are exacerbated by SW, and autonomic dysfunction is common.

shift work

A staffing arrangement in which some employees work during the day and others in the evening or at night. Shift work is a common method of scheduling used in many industries to maximize productivity over a 24-hr day and in health care, where patients' needs may arise at any time of the day or night. A great number of persons work regularly at night, either on a permanent or rotating schedule. In most of these workers, adaptation to the altered work schedule is imperfect; sleep disturbances and other medical and psychosocial problems have often been found in shift workers. Among other problems, many night-time or rotating shift workers often have family obligations during the day, which compromise their ability to obtain adequate rest before or after work.

The previous findings have been used to bring about a relation between circadian rhythms and night shift/rotational shift so that organizations are able to understand the difficulties faced by workers/employees working in shift work. The author has also used textbooks of General Medicine to know the meaning of circadian rhythms and the consequences as well as its relationship with the sleep wake cycle.

Night shift work is preconditioned by the need to provide 24-hour care and may result in reduced sleep due to desynchronization in the regulation of endogenous circadian rhythms, leading to accumulated "sleep debt", sleepiness and fatigue, which, in turn, results in increased physical and psychological health problems in nurses [4].
