night shift This means going against the majority of society, in terms of hours. Still, we think that with time and custom one becomes adapted to live this way.
However, it seems that is not the case. According to a study, there are some people who like result of a biological traitThey are unable to properly rest on these schedules, even though they have spent years trying to accommodate them.
internal clock mismatch
The work was carried out by researchers from the University of Warwick (United Kingdom) and the University of Paris-Saclay (France) and published in Scientific Medium ebio medicine, supervised two groups of French hospital staff, one on the night shift and the other on the day shift, during their working days and their free time. Using this method, they found that some workers were having difficulty adjusting to their work shifts, even after years of working.
Specifically, this subgroup showed significant disruption in their sleep cycles and in their cardiac rhythms (The alternation of sleep and wakefulness, “established by the biological clock of the brain and which coordinates the peripheral clocks of other organs”).
In addition, for this monitoring the researchers used the data telemonitoring device (for example, smart watches), so an added value of the study is that it provides evidence in favor of the usefulness of these technologies in research.
long term risk
Using this approach, they found that night shift workers had on average half the regularity and quality of sleep as their day shift colleagues. about half also showed Disruption of the natural rhythm of body temperatureWhich naturally varies throughout the day.
In addition, these data were compared with questionnaires about chronotype (the ‘natural’ distribution of each person’s activity throughout the day) evidenced that their sleeping hours did not coincide with their own, so they were sleeping “out of sync with their internal clock”.
Most notably, some of the oldest night workers Still show these qualities, and even more pronounced than those who had spent fewer years working at night. This, they note, has previously been associated with significant long-term health risks.
