This article discusses the 룸 알바 서울 특별시 differences between day and night shift workers in Japan. Rotating-shift work is associated with increased risk of ischemic heart disease, while fixed-night work does not in this study. Shift workers are less likely to be motivated to change their unhealthy behavior when compared to day workers, especially those who work long hours.
In Japan, shift workers may work afternoon shifts, day shifts or fixed night shifts. Rotating shift work includes shifts that change one day to the next while fixed night work involves a defined shift pattern. Afternoon shifts may be one 8-hour shift or three 8-hour shifts. For example, if a worker works what time each day will vary depending on the type of shift they are working. Different types of workers may include alternate workers who work different hours each week and one same worker who works the same hours each week. The term ‘shift work’ can refer to any number of different types and forms of employment that involve working outside of traditional 9am-5pm office hours. An example of this is when a worker works three 8-hour shifts in a single week, with the number and type of shift varying from week to week.
Day shift workers usually have a regular 8-hour working day from Monday to Friday, while night shift workers may have to work long hours, including Saturdays and Sundays. In Japan, the number of employees who work shifts is increasing every year. Workers in certain professions such as law enforcement, healthcare and flight attendants are required to work night shifts more than 75% of the time. Pilots and flight attendants also often have to work long hours due to the nature of their jobs.
In Japan, day and night shift workers face different challenges. Working rotating shifts has been linked to sleep problems, miscarriages, preterm birth, menstrual disorders and other adverse effects. This is due to the changing exposure of day and night sleep during the week.
The most challenging days for night shift workers in Japan are when the duration of the work hours is more than 8 hours and when rotating shift work is increased. As previous studies have focused on knowledge about the types and number of hours per week for night / shift workers, future studies should focus on how to manage long working hours and required shifts for these workers. Fixed night workers in Japan may face increased health risks due to their longer working hours, making it difficult to change their sleep habits. This can be especially true for those who are required to work shifts that occur more than once a week. Studies have found that long-term exposure to rotating shift work can be detrimental to health, so it is important that future studies focus on ways to improve health outcomes in these cases. Overall, day and night shift workers in Japan face different levels of exposure depending on the duration of their work hours and the types of shifts they are required to take.
Night shift workers have been observed to have a more unique work schedule compared to day time workers, with many of them working 5 night shifts in a row. This difference in work schedules has an effect on the motivation of the workers and the types of behaviour they are likely to display while on duty. A recent observational study assessed dietary intake and physical activity among night shift workers and daytime workers in Japan. The study showed that shift workers typically had 3 fewer shifts per month than daytime workers, which may modify their motivation levels at work as well as their total energy intake. Furthermore, a longitudinal study showed that night shift workers were more likely to be overweight or obese compared with daytime workers regarding total energy intake. Overall, different work schedules between day and night shift workers can have an effect on their dietary habits, physical activity levels and overall health status. It is therefore important for employers to provide adequate workplace support for both groups in order to minimize health risks associated with long-term exposure to different shifts.
In a recent cohort study of Japanese male workers spanning 14 years, it was reported that among the 8279 shift workers, 18,163 men worked in day shifts and 6116 worked in night shifts. Those that worked in a rotating shift work schedule had an increased BMI over 12 years compared to those working only day shifts. Similarly, a 10-hour night shift schedule was associated with an increased risk of ischemic heart disease after 74 years of follow-up compared to those working 7 hours or less. However, the risk of ischemic heart disease for those working 10 hours or more per day did not increase significantly for both groups. This suggests that the duration of daily work may have a greater effect on health risks than the shift type itself.
Day shift workers and night shift workers in Japan have different working patterns, which can impact on their health. Working day shift involves performing a fixed day of work from 9am to 5pm. Fixed night work is undertaken from 5pm to 1am and rotating shift work is performed where the employee rotates between day and night shifts. In a study of 17,649 men, it was found that 864 (4.9%) engaged in rotating shift work and 14,774 (83.7%) reported having breakfast every morning before starting their day. The study also found that the men who worked rotating shifts had higher sexual functional scores than those who did not, suggesting that being on a different shift could affect sexual functioning. In terms of age distribution, it was revealed that less than 10% of the men were in their 40s when they participated in the study while just over 10% were over 60 years old. This could be indicative of the fact that younger people are more likely to undertake rotating shift work due to its higher levels of pay and greater flexibility compared with other forms of employment. It is important to take breaks during any form of extended working hours as this can help reduce stress levels and maintain good health overall.
In Japan, the standard day shifts are 8 hours and following night shift is 9 hours; however, working night shift is considered to be more taxing. Therefore, shift schedules are adjusted accordingly to accommodate for this. Night shifts in Japan can range from 12 hours to as long as 24 hours and has been reported by paramedics in Australia that includes two days of work followed by two days of recovery. This current rotating shift has been known as the ‘night shift one’ system which yields similar trends with other roster systems. Studies have also shown that after a second day of recovery, there was an increase in alertness levels with no decline in performance.
This suggests that workers may be able to adjust to shift work after a short period of time. In Japan, there are two types of shift work, day and night shifts. Swing shift is common in the healthcare industry where a shift takes place over a 24-h period.
