Lack of sleep will increase multiple health risks. Some scholars believe that sleep acts as “electric forks” to help the body heal. However, shift work has been proven to cause sleep disorders and increase the risk of disease the heart, dementia, and emotional. Night shifts It is also classified as a “possible human carcinogen” by the International Agency for Research on Cancer. And whether it’s a fixed night shift or a rotating shift, it will have an effect, because workers often return to their normal work and rest during holidays, which is a hidden form of “self-management jet lag “, making it even bigger. difficult to sleep well.

Chen Wing-yan, an associate professor in the Department of Psychiatry at CUHK, said that sleep is like “electric forks” for the human body, which restores the energy used during the day and eliminates bad substances in the body. muscle recovery and immunity. Humans are diurnal animals, and their biological clock is “work at sunrise and rest at sunset”, and the greater the difference between shift work or overnight work and the natural rhythm, the more pronounced the effect on the body, such as jet testing. delays, prone to eye strain, Fatigue and gastrointestinal discomfort, long-term shift work will increase the risk of diabetes, heart disease, dementia, mood disorders and cancer.” The International Agency for Research on Cancer has listed night shift work as a possible human carcinogen.”
Less exercise among shift workers exacerbates risk
Chen continued to point out that according to the guidelines of the International Labor Organization, if you start working for no less than 7 consecutive hours between 12:00 pm For example, some people have morning and night type physiques, and the work intensity, duration and rest periods during shifts are also affected.”
He continued to point out that shift workers generally do less exercise, and like to snack and drink alcohol when they are on duty at night, which will also expose them to obesity and increase health risks. In addition, people who suffer from sleep deprivation are more likely to get sick when they come into contact with viruses, such as the common cold virus; lack of sleep when ill can also affect the speed of recovery.
Experts point out that some shift workers will get up early and go to bed late like ordinary people during holidays, which will cause a biological clock disorder.
“Changing time zones” during holidays is even more harmful to the body
Even young people don’t “stay up all night”. Chen pointed out that international studies have shown that loss of sleep has a significant impact on health in young and old groups. When going to work, or working morning, afternoon and evening shifts, some people will still to get up early and go to bed late. like ordinary people during holidays, which is like going to a different time zone to rest after work, which will also cause chaos in the biological clock.”
Chen pointed out that middle-aged people are mostly middle-aged people who seek help for sleep disorders caused by shifts. “One of the reasons is that the quality of sleep will decline with age. Work during the day, so that the body is affected even more.” In one case, the patient was suffering from insomnia and dozing off at the same time. It is more difficult to adjust the sleeping time after the early shift, and there will be emotional problems.” He suggested that shift workers should make a sleep plan to ensure that they fall asleep regularly every day and sleep for 7 hours. ” It’s best not to go back to the night shift. In the morning, I went out to have fun with my friends, and I didn’t rest regularly.”
