<p>A recent study has suggested that most people who regularly work night shifts suffer from some kind of sleep disorder, including insomnia. In the study, which was <strong><a href="https://www.frontiersin.org/articles/10.3389/fpsyt.2023.1233640/full">published in Frontiers in Psychiatry </a></strong>on Dec 7, researchers from the Netherlands and Belgium collected work and sleep data from 37,662 individuals.&nbsp;</p>

<p>"In this cross-sectional study, prevalence rates of short sleep (≤6 h), long sleep (≥9 h) and sleep disorders (screened with Holland Sleep Disorders Questionnaire), and associations between these sleep variables and socio-demographics (age, sex, education, living companion(s)) were analyzed using binominal logistic regression analyses," the study said.&nbsp;</p>

<p>"Shift work is related not only to curtailed sleep and shift work disorder but also to a plethora of sleep disorders, including insomnia, sleep-related breathing disorders and sleep-related movement disorders," it added.</p>

<h2><strong>The findings</strong></h2>

<p>Researchers said that in the total sample, all socio-demographic factors affected prevalences of short, long, and disordered sleep, consistent with previous studies. "Compared to day workers, shift workers more frequently reported short sleep, most prominently night workers (26 vs. 50%) (<em>p</em>&nbsp;&lt; 0.001)," the researchers said.</p>

<p>Six common sleep disorder categories were screened for the surveys - insomnia, hypersomnia, parasomnia, sleep-related breathing disorders, sleep-related movement disorders, and circadian rhythm sleep-wake disorders.</p>

<p>"In night shift workers the level of education had the strongest associations with disturbed sleep with a two-fold higher prevalence of short and disordered sleep in low relative to academic educated groups (all&nbsp;<em>p</em>&nbsp;&lt; 0.02)," the study further said.&nbsp;</p>

<p>Over a quarter of regular night-shift workers (26 per cent) reported more than two or three sleep disorders, and 51 per cent of people working such shifts tested positive for at least one sleep disorder.</p>

<h2><strong>Rotational shifts suggested</strong></h2>

<p>Professor Marike Lancel from the University of Groningen in the Netherlands told Science Alert, "We showed that compared to working regular shifts during daytime hours, working other shift types is associated with a higher occurrence of disordered sleep, particularly in rotating and regular night shift work."</p>

<p>The researchers suggested that rotational shifts were generally advised, particularly fast-forward rotating work schedules, with "night work as short as possible and plenty of resting days in between to recover from the accumulated sleep deficit."</p>

<p>"To prevent sleep curtailment and sleep disorders, employers/occupational health practitioners should encourage good sleep health and give tools to deal with shift work as well as possible, both promoting optimal sleep during the resting period and wakefulness during working hours," they added.</p>

Study: Most people working night shifts develop some kind of sleep disorder

<p>Scientists may have identified the phenomenon that affects and disrupts the health of millions of shift workers who grind throughout the night while the rest of us sleep.</p>

<p>Working while fighting against the body clock may lead to weight gain, diabetes, cancer, depression, and poor heart health, as various studies indicate.</p>

<p>Now, new research has revealed the link between ‘when’ you eat and the impact on your health. The conclusion was driven by a study on rodents, which suggested that a change in appetite behaviour may be seen when sleep-wake cycles and day-night cues don't line up.</p>

<h2><strong>How was the experiment conducted?</strong></h2>

<p>A group of scientists at the University of Bristol in the United Kingdom conducted research into the connection between hormones associated with sleep-wake cycles and the daily eating habits of rats. They discovered that disruptions in circadian rhythms (physical, mental, and behavioural changes that follow a 24-hour cycle) had a profound impact on the rats' eating behaviours.</p>

<p>To disrupt the rats' natural bodily rhythms, the researchers administered corticosterone, a hormone similar to cortisol in humans, either in synchrony with or out of phase with the light-dark cues. Corticosterone levels in rodents increase significantly before waking and gradually decrease throughout the day.</p>

<p>Rats with undisturbed rhythms, when exposed to poorly timed corticosterone surges, consumed the same daily amount of food as the rats with in-sync rhythms and a control group that received no infusions.&nbsp;</p>

<p>"When we disturb the normal relationship of corticosterone with the day-to-night light cycle, it results in abnormal gene regulation and appetite during the period of time that the animals normally sleep," University of Bristol neuroscientist and study author Stafford Lightman explained.</p>
