What are the disadvantages of working night shifts? What are the disadvantages of working night shif

The first disadvantage of working the night shift is that it is unsafe, and the second is that it is not good to sleep at night. There is harm to the body.

First, it affects the quality of people's sleep.

The night shift is black and white, although it seems that the hours of working during the day and at night are the same, and working the night shift is the same as going to work, but at different times. However, the truth is that if you sleep during the day, it is not the same as at night! It is obviously very noisy during the day, which is not conducive to people's rest, and it is easy to be disturbed by daytime light, and the quality of sleep is greatly discounted.

Second, the risk of carcinogenesis is greatly increased.

Because the night shift disrupts a person's normal biological clock, when they should be sleeping but working, many hormones that are secreted at night will not be secreted when they sleep during the day! For example, melatonin, which is a hormone that can inhibit the production of tumors, if you work at night, then the lights during work will inhibit the secretion of melatonin, and during the day, even in the dark environment, it will not be secreted, thus increasing the probability of tumor development.

Thirdly, it leads to changes in normal eating habits, leading to the occurrence of gastrointestinal diseases.

Many people are troublesome, and eat cold food or instant noodles before going to bed during the day and working overtime at night when they are hungry, which is very bad for the stomach and intestines over time, and it is easy to get stomach problems. Some people will say that he just likes to work night shifts, you know, a person's life and rest habits over the years can not be changed in a month or two, and forcing him to work at night is taking his own life to work!

Fourth, it leads to a decrease in the body's immunity.

Because of night shifts, although people's work and rest time are easy to be reversed, it is difficult to reverse various physiological activities of the human body. Therefore, working night shifts can easily stop the physiological activities that would have occurred at night rest, thereby disrupting the normal physiological and metabolic functions of the human body, greatly reducing people's immunity and resistance, and increasing the probability of disease.

Fifth, it affects the nervous system.

Long-term night shifts are prone to insomnia, forgetfulness and anxiety and other mental symptoms, which lead to disorders in the nervous system and harm the normal metabolic function of human organs and systems.

1. Poor eyesight.

Long-term exposure to unnatural light due to frequent night shifts can lead to vision loss and fatigue over time. In particular, people who often work in front of computer screens or monitors can reduce the burden on their eyes, and their vision will also deteriorate, and even myopia may occur.

2. The nervous system is damaged.

Compared with nighttime, the daytime environment is noisy, and daytime sleep is easily affected by a variety of factors, such as the sound of family cooking or watching TV, and the noise of children, which will inevitably hinder the quality of sleep. Long night shifts can lead to poor concentration, memory loss and increasingly sluggish reactions, and greater mood swings.

3. Digestive system diseases.

Eating habits can also change with night shifts, such as not eating any food during the day, and eating fast food or instant noodles at night when you feel hungry during overtime, which can hurt your stomach over time. There are also some people who prefer to drink strong tea and strong coffee for refreshment, which can easily cause peptic ulcers and chronic gastritis for a long time, and even increase the risk of gastrointestinal cancer.

4. Endocrine system disorders.

Working night shifts for a long time will cause hormone levels to be disordered, hormone imbalance, and then weaken immunity and increase the risk of disease, such as colds and fevers every once in a while, and mouth ulcers. In particular, women who work night shifts for a long time are prone to endocrine disorders, and the menstrual cycle and ovulation cycle are also disordered, increasing the risk of uterine cancer and breast cancer.

5. Increased blood pressure.

There are rules to follow in various physiological activities in the body, such as the peak of hematopoiesis in the evening and the low tide in the early morning. Circadian rhythm reversal can increase blood pressure, increase serum cholesterol levels, and promote the release of inflammatory factors, which in turn induces chronic diseases.
