As the pace of 2022 approaches, will the "hit workers" fall into the fear of being dominated by 996 again?
Today gives you a reason to reject 996! After studying a series of data, scientists concluded that compared with the standard working hours of 35 to 40 hours per week, the physical health of people who work 55 hours or more per week is not optimistic, and "996" has no "blessings" and only brings "baggage" to the body.
Recently, a study published by The Lancet Regional Health-Europe showed that working more than 55 hours a week increased the risk of bacterial infections, diabetes, musculoskeletal diseases, and injuries, and was associated with a 52% increased risk of dying from cardiovascular disease before the age of 65.

The investigators previously found at least three limitations to the evidence on working hours and disease risk: first, although there were many studies on specific health outcomes, the coverage was relatively narrow, with few studies simultaneously assessing the association between health status and long hours; second, the study process did not limit the length of follow-up; and third, although survival with all-cause mortality as an index was a fundamental health endpoint, few studies assessed its relationship to long working hours.
To address these limitations, the researchers examined the associations between 46 common physical and mental health conditions and 4 different causes of death and long work, and limited disease and mortality surveillance to age 65.
The investigators first pooled data from individual participants from two Finnish prospective cohort studies. It included data on the 50 disease and death endpoints the researchers needed, as well as cohorts from Sweden, Denmark and the United Kingdom that participated in the comparison.

The study divided working hours into "less than 35 hours", "35-40 hours", "41-48 hours", "49-54 hours" and "≥55 hours/week". The first category includes part-time workers and the second category represents a reference group of full-time workers with standard working hours. Working 55 hours or more per week is defined as working long hours.
In the preliminary analysis, 2747 (4.6 percent) of the 59,599 participants were classified as working long hours (≥55 hours/week). This work pattern is more than three times more common among men (9.6%) than women (2.9%) and is more prevalent relative to low socioeconomic groups. In addition, the average follow-up time for the event was 13.8 years and the mortality rate was 15.3 years.
Of the 50 diseases, 14 of them (28%) had morbidity and mortality risks associated with long hours of work. Therefore, after adjusting for gender, age, socioeconomic status, ≥ 55 hours/week with working hours was statistically significant (p. But it's worth noting that working long hours is not associated with all-cause deaths.

Finally, the researchers examined the chronological sequence of health outcomes associated with long hours of work, including bacterial infections, diabetes, injuries, musculoskeletal disorders, and cardiovascular death. The results showed that diabetes was associated with cardiovascular death and bacterial infections; bacterial infections were associated with diabetes. In addition, there was a weak correlation between diabetes and musculoskeletal disease, bacterial infections, musculoskeletal diseases and diabetes, and injuries and musculoskeletal disorders.

Taken together, the above findings suggest that in Europe, working more than 55 hours a week increases the risk of bacterial infections, diabetes, musculoskeletal diseases and injuries, and is associated with a 52% increased risk of dying from cardiovascular disease before the age of 65. Therefore, although work is important, the body is the capital of the revolution, and we must cherish it!
