Is it better to work night shift or day shift?

Of course, it is good to work in the day shift, and the influence of working in the night shift is as follows:

1, night shift leads to the decrease of melatonin secretion which inhibits tumor production.

The night shift disrupts the normal biological clock of the human body, but it is working when it is time to sleep. However, melatonin produced by tumors that the human body can inhibit is generally secreted at night, and light will inhibit melatonin secretion. Scientists believe that low melatonin levels will increase the risk of cancer.

2. Night shift leads to lack of sleep, which affects the normal function of immune system.

People who work at night shifts are prone to sleep disorders, but they can't sleep because of excitement when they should sleep during the day, resulting in insufficient sleep. Lack of sleep will make the human immune system more fragile and reduce the ability to fight potential cancer cells.

This is another possible factor for the increased risk of cancer.

3, biological clock disorder will also affect cell division, deoxyribonucleic acid (DNA) repair and other essential human functions.

The human body is a complicated machine. Many studies have shown that sleeping at night is an important stage for the human body to repair, so the disruption of this time may affect the human body to repair and cause health hazards.

4, black and white upside down life will affect endocrine disorders.

Long-term "black-and-white" life will make human life rhythm disorder, neuroendocrine system dysfunction, estrogen and progesterone imbalance. The high incidence of female tumors is related to estrogen and progesterone, and the imbalance of these two hormones may lead to hysteromyoma, endometrial cancer and breast cancer.

Taking breast cancer as an example, if it is stimulated by bad factors such as staying up late for a long time, it will easily lead to endocrine disorders, decreased immunity, decreased production and release of thymosin by thymus, decreased monitoring ability and phagocytic ability of lymphocytes and macrophages on mutant cells in the body, and easily lead to cancerous masses.

Coriano, head of the Carcinogen Classification Department of the International Agency for Research on Cancer, said that there are enough samples to show that the cancer incidence of night shift people is increasing, but "we can't rule out other possible factors".

Key points of night shift maintenance:

First of all, we should pay attention to the reasonable arrangement of diet and insist on three meals a day plus a night shift meal. It is advisable to eat 80% full before going to work, don't go to bed hungry after work, and don't give up eating lunch because you are sleepy.

Because working at night generally consumes more energy than working during the day, it is necessary to eat more nutritious and digestible vegetables, lean meat, fresh fish, eggs, bean products and fruits, especially foods rich in vitamin A, such as animal liver and freshwater fish, which can improve people's adaptability to dim light and prevent eye fatigue.

A better sleeping environment will improve your sleep quality. The windows of the room can be covered with black cloth to artificially create a "dark night". Washing feet with hot water before going to bed also helps to fall asleep. If the environment is noisy, you can put a set of earplugs made of absorbent cotton in your ears.

Doing some proper cultural and sports activities during the night shift can achieve the purpose of quickly relieving or alleviating fatigue.

People who engage in heavy physical labor take part in relaxed and happy entertainment activities; Those who engage in local manual labor should strengthen the activities of the opposite limb with a certain intensity; If you bend over often, you can do more stretching activities; Mental workers should strengthen their whole body activities.
