Researchers speculate that prolonged exposure to artificial light at night tends to cause changes in body chemicals that interfere with the rhythm of hormone secretion, thereby inhibiting the secretion of melatonin by the pineal gland in the brain, while lack of sleep and disruption of the physiological clock also tend to make tumor generation. Currently, only Denmark has listed night shift as an occupational hazard for breast cancer. In fact, women who work late at night for a long time not only increase the risk of breast cancer, but also increase the risk of the following diseases.
1. Dark circles under the eyes
Dark circles under the eyes and mental fatigue are only the surface symptoms caused by staying up late. The skin of the eyes is already very loose, so if you do not rest well, the metabolism of the eye cells is very poor, the cells age quickly, while the new cells appear slowly, and the old cells accumulate in the eyes in large quantities, then eye bags appear.
2, body immune disorders
If the immune disorder is manifested in the kidneys, it will produce nephritis, in the skin, it is lupus erythematosus, and in the joints, it is rheumatoid arthritis.
3.Damaged skin
Generally speaking, the skin enters the evening maintenance state from 10:00 pm to 2:00 pm. If you stay up late for a long time, it will destroy the normal circulation of the body’s endocrine and nervous system. Nervous system disorders will be dry skin, poor elasticity, lack of luster and other problems; and endocrine disorders will be the skin acne, acne, chloasma class, dark spots and other problems.
4.Decrease in resistance
In the late night on the body caused by a variety of damage, the most common is to make people often fatigue, mental discomfort, body resistance to decline. For people with weak resistance, respiratory diseases such as colds and flu, gastrointestinal and other digestive diseases will also come to the door. This is mainly because the normal physiological cycle is disrupted when people stay up late, the body’s normal ‘response’ system is damaged, resistance will also decline.
5, memory loss
Normally, a person’s sympathetic nerves should be rested at night and excited during the day to support a person’s day’s work. But the sympathetic nerves of those who stay up late are excited at night, the so-called a relaxation, after staying up late the next day, the sympathetic nerves are difficult to fully excited. This will be no spirit during the day, dizziness, memory loss, inattention, slow reaction, forgetfulness and dizziness, headaches and other problems. Over time, there will be neurasthenia, insomnia and other problems.
6, Yin deficiency fire
For people who stay up late, the body is working overtime, so it is easy to have functional disorders, Chinese medicine is considered to be Yin deficiency fire, which is often referred to as fire. In addition, when people stay up late, life is often irregular, because to stay up late, some people will eat more dinner, and some people stay up late when hungry will also eat a big meal, so people who stay up late often have gastrointestinal problems, such as indigestion.
7, vision loss
The damage of staying up late on people’s eyes is not just the simple appearance of ‘panda eyes’. Long time overload eye, but also make the eyes appear pain, dryness, rising and other problems, and even make people suffer from dry eye disease. In addition, eye muscle fatigue can also lead to temporary vision loss. Overexertion caused by prolonged late nights may also induce central retinitis, which causes blurred vision, dark shadows in the center of the visual field, distortion, distortion, shrinkage, and color change of visual objects, resulting in vision aggregation loss. Generally speaking, this eye disease is often sudden onset after staying up all night.
8, cervical disease
More than 20 gynecologists according to the study and analysis of the results of physical examinations of women who often stay up late and black and white, about 40% of women are suffering from various cervical diseases, some of which have developed into malignant lesions. Among them, white-collar women aged between 25 and 50 are more likely to work at night and stay up late compared to other groups of women, which means that these groups have a greater chance of being attacked by cervical diseases.
This is because long-term black and white reversal will change the body’s original biological clock, which will lead to disruption of the body’s life rhythm. This disruption will lead to a series of endocrine disorders and affect the ovulation cycle, which may lead to dysmenorrhea, irregular menstruation, and even endometrial cancer due to the decline of body resistance and endocrine disorders. Terribly, for women who work at night, cervical disease may not have any conscious symptoms in the early stage, but with the development of the disease will gradually appear contact bleeding, increased vaginal discharge, discharge of light blood or with foul smell, and in the late stage may appear symptoms such as back and leg pain, lower abdominal pain, swelling of lower limbs, difficulty in defecation and urination, blood in urine and blood in stool.
9.Increase the risk of heart disease
People with disrupted work schedules are not as easy to adapt their bodies as they think, not only will their tempers get worse, the chances of getting heart disease are also higher. Especially for middle-aged and elderly women, staying up late for a long time will disrupt their biological clocks. Thus, if the “black and white” for a long time, will make women at increased risk of heart disease.
