Register The impact of shift work on health Published Published Mon 11 Jan By James McIntosh When Dolly Parton sang of working 9 to 5, she expressed concern for people barely getting by with a hard life of routine that only seems to benefit the boss.
But what about all those people working less conventional hours, including night shifts? Parton be just as concerned about their welfare? Shift workers, such as doctors, flight attendants, bartenders and police officers, have been found to be at a greater risk of certain chronic diseases.
Shift work has its own demands that set it apart from jobs with traditional working hours. Shift work has its benefits; it can be more convenient from a child care perspective, is sometimes better paid and can allow workers time for other activities, such as study.
However, the medical and scientific communities are continually reporting that shift work can increase the risk of certain disorders and have a negative impact on the overall well-being of employees.
In this article, we take a look at what has been reported recently about the effects of shift work, what reasons could possibly be behind these findings and what people working shifts can potentially do to lower their risks of various health problems.
Shift work in the US Shift work tends to be classified as any work schedule that involves hours that are irregular or unusual in comparison with the traditional daytime work schedule that usually occurs between 6 am and 6 pm. The term shift work can, for this reason, refer to working evenings, overnight, rotating shifts or irregular employer-arranged shift patterns.
Of these, the most common alternative shifts are evening shifts, with working hours usually between 2 pm and midnight, and irregular shifts with a constantly changing schedule. Recently, the BLS reported that the proportion of full-time wage and salary workers employed working alternative shifts now sits at While there has been a slight drop in the number of white Americans working these hours - from In Maythe percentages for these groups were Shift work is most commonly found within industries that provide services around the clock, such as food services, transportation, health services and protective services like the police force.
At first glance, it appears as though the main factor connecting shift workers is that they work different hours to the typical "9-to-5" routine. However, multiple studies report that there is something else that connects bar staff, long-distance truck drivers, nurses and police officers - an increased risk for certain diseases.
Previous studies reported by MNT Medical News Today have reported on various studies associating shift work with an increased risk of certain health problems. These associations have ranged from the somewhat predictable to the surprising. In Julya meta-analysis published in Occupational and Environmental Medicine suggested that shift workers face an increased risk of type 2 diabetes.
A study suggested shift work may raise the risk of type 2 diabetes. The authors theorized that rotating shifts made it more difficult for workers to maintain a regular sleep-wake cycle, negatively affecting sleep quality and potentially weakening insulin resistance.
Then, in Novemberanother study published in the same journal suggested that shift work could impair the functioning of the brain. Study participants who were currently working or had previously worked shifts scored lower in tests assessing memory, processing speed and overall brain power than participants working traditional daytime hours.
In addition, working rotating night shifts for 15 years or more was found to potentially raise the risk of lung cancer mortality. A quick perusal of these studies indicates another factor that shift workers are likely to have in common - disruptions to the sleep-wake cycle.
Shift work can lead to workers sleeping at strange or varying times of day, potentially resulting in reduced amounts of sleep. But how much of an impact can sleep disruption have on an individual's health?
What are circadian rhythms?“A good laugh and a long sleep are the best cures in the doctor’s book.” – Irish Proverb The evidence for the health benefits of adequate, restful sleep is overwhelming.
Decades of research has shown that sleeping between 7 and 9 hours per night can relieve stress, reduce the risk of many chronic diseases, improve memory and cognitive function, and may even help with weight loss.

REM sleep occurs in cycles of about minutes throughout the night, and it accounts for up to % of total sleep time in adult humans, although the proportion decreases with age (a newborn baby may spend 80% of total sleep time in the REM stage).
In particular, REM sleep dominates the latter half of the sleep period, especially the hours before waking, and the REM component of each.
