Several studies have already dealt with the impact of night work on health. Recent work has made it possible to understand that night work also generates poor synchronization of the biological clock that can impact certain cognitive functions such as memory.
In 2016, a study by ANSES in France suggested that night work has a probable effect on the risk of cancer . The researchers also mentioned other problems such as sleep disorders, weight gain, mental health or even cognitive performance. In 2014, another French study also highlighted the risks of acceleration of cognitive aging because of night work.
In a new study published in the journal Occupational &Environmental Medicine, researchers from the Department of Psychology at Sigmund Freud University (Austria) analyzed many factors among 19,000 night workers . The sample included representatives among health professionals, first aiders, workers and other night watchmen (security).
Among the factors analyzed, we find vigilance, processing speed, memory or even impulse control. However, according to scientists, night workers have a poorer memory and are less alert. The reason given is none other than a lack of synchronization of their biological clock , in other words a disruption of their circadian rhythm. Indeed, these people are often unable to sleep normally, which would not be without consequence.
For researchers, the pace of life of workers would impact their responses to certain situations . To the extent that the processing of information is less clear, this notably increases the risk of accidents at work, in addition to other errors that can have multiple repercussions. On the other hand, it is possible to correct the possible side effects of this staggered pace of work. The researchers advise, for example, to take breaks and, if possible, short naps during the night. For example, micronaps of less than ten minutes allow physical and mental recovery . This then has beneficial effects on stress, boosting energy and improving concentration.
Finally, scientists encourage the development of quality scientific literature on the subject. Further work could eventually lead to the implementation of practical interventions with the aim of overcoming neurobehavioral disorders related to night work.
