Shift Work and Sleep

Replacement personnel are those who follow the regular work schedule "9 o'clock to 5 o'clock" except working days. Over the past few decades, the United States has been increasing its reliance on shift workers to meet the needs of globalization and 24-hour society. From a competitive point of view, shift work is an excellent way to increase production and customer service without significantly increasing infrastructure. According to the Bureau of Labor Statistics, millions of Americans are considered shift workers such as doctors and nurses, pilots, bridge builders, police, customer service representatives, commercial drivers, etc.

However, shift work has the potential productivity advantage, but it also has many inherent risks. Some of the most serious and lasting problems facing workers are frequent sleep disturbances and associated excessive sleepiness. Drowsiness / fatigue in the workplace can lead to carelessness, absence, accidents, mistakes, injuries, and death. This problem is further worrisome if you think that shift workers are often engaged in the most dangerous work such as firefighting, emergency medicine, law enforcement agencies, safety. Administrators and decision-makers responsible for creating and executing employee's working time rules will address the specific problems of 24-hour staff to make such employees successful and benefit from it is needed. To deal with these problems, some investment may be required in advance for training and other measures, but the most important thing is to improve workers' sleep to increase productivity . In fact, considering the most notorious modern disasters such as annual costs, thousands of deaths, Columbia Space Shuttle failures, ignoring shift worker's needs is reckless and irresponsible. The collapse of Exxon Valdez is due to human fatigue

According to the international sleep disorder classification, shift workers are at high risk of various chronic diseases such as heart disease and gastrointestinal disease. Is this related to the fact that shift workers happen in the middle of the night and are active?

Shifted work increases the risk of developing many diseases. The shift work sleep disorder is a circadian rhythm sleep disorder characterized by insomnia, excessive drowsiness, or both. Shifted work is considered essential for diagnosis. For workers with shift work, especially men, the risk of type 2 diabetes increases. People working at rotation are more vulnerable than others. Women working at night shift have a 48% higher risk of developing breast cancer. This may be due to a change in circadian rhythm. Melatonin (a known tumor suppressor) is usually produced at night and slow alternation may interfere with its production. The International Cancer Research Organization of the World Health Organization raises the possibility of carcinogenic substance as "shift work accompanied by disruption of circadian rhythm". Shift work may also increase the risk of other types of cancer

Sleep disorder in shift work occurs when your work schedule is not synchronized with your biological clock. In our 24-hour society, a lot of people have to do a night shift, a breakfast, or shift work. These schedules force you to work as your body instructs you to go to sleep, and these schedules sleep when your body signals that you wake up. Some people are better suited for shifts than others, but the sleep quality of most shift workers is lower than the sleep quality of day workers. Due to lack of sleep, you may be suffering from sleepiness or mental sleepiness at work. This reduces your productivity and risks injury

A sudden sleep deprivation occurs when there is no rest during a long break and when shifting at night, the worker sleeps in the morning and wakes up in the afternoon before the work shift. Night shift workers who can not sleep well during the day may wake up for more than 18 hours at the end of turnover. The effect of acute sleep deprivation can be compared to the damage caused by alcoholism, corresponding to 0.05% BAC for 19 hours of arousal, and a wakefulness of 24 hours corresponds to 0.10% BAC. Most of the effects of acute sleep deprivation can be offset by nap and longer nap is more beneficial than shorter nap. Some industries, especially the fire department, traditionally acknowledge workers sleep between service calls while on duty. In an EMS provider study, a 24-hour shift was associated with a higher frequency of negative safety outcomes than a short shift
