Stay up late to prevent cancer

      In the past, many people know that bad habits, such as smoking, alcoholism, overeating and other cancer-related. Recently, the International Cancer Research Institute will be included overnight to cause possible carcinogenic factors. Perhaps you will be surprised: stay up late or after night shift, sleep well during the day, the total sleep time did not reduce ah, said the night shift may be cancer is not too evil? Let's take a look at the relevant research report. The following are the same as the "
      Open up to sleep or stay up late: the risk of cancer high American scientists the latest research shows that at night to sleep or stay up all night, is one of the major factors leading to breast cancer in women. A study conducted jointly by the National Cancer Institute and the National Institute of Environmental Health Sciences provides the first evidence of the relationship between unnatural light and cancer. A large number of studies have shown that the risk of breast cancer is up to 60% for those who need night work, such as nurses and air attendants. In addition, the study also shows that the frequent night shift in the incidence of male prostate cancer is also higher than the male class. The following are the same as the "
      Reason: Melatonin secretion of melatonin (Melatonin, MLT, chemical name of N-acetyl-5-methoxytryptamine) is mainly by the human brain called pineal tissue secretion of hormones, the first by A dermatologist was drawn from the cattle in 1958. As scientists in the experiment found that this hormone can make frog body color lighter, so named melatonin. Human melatonin secretion usually 2 to 6 years after birth to reach the peak, 6 to 8 years old to adult levels, 8 to 13 years old level of secretion continued to decline, to adolescence has increased, and then gradually decline. The following are the same as the "
      The secretion of melatonin in the human body has obvious circadian rhythm, its main physiological function is:
      1. Maintain the physiological circadian rhythm, is conducive to sleep. The following are the same as the "
      2. Prevention of cardiovascular disease, Alzheimer's disease, Parkinson's disease, diabetes and cataracts and other diseases. The following are the same as the "
      3. Increase the body's immune function, help anti-aging and inhibit the growth of tumor cells, thereby preventing cancer. The following are the same as the "
      It can be seen that melatonin is a very important human endocrine hormone, if the lack of may lead to serious consequences. Melatonin secretion is reduced: cancer cells are rampant
      Researchers in the United States believe that nighttime light can hinder the secretion of melatonin, and melatonin plays an important role in the development of cancer. The evidence is that the researchers transplanted the lumps of breast cancer to mice and injected them into the mouse's blood from the morning or night after exposure to light. The results showed that the early morning (that is, after sleep) the blood of the growth rate of cancer cells slowed by 80%, and injected through the light through the blood, the growth of cancer cells accelerated. The following are the same as the "
      Prevention of cancer: The following recommendations should be adopted
      1. Turn off all lights when you sleep. Because sleeping in the dark room is conducive to the manufacture of melatonin. The following are the same as the "
      2. Try to stay 9 hours a day as much as possible. The following are the same as the "
      3. After getting up in the morning to walk outdoors. The following are the same as the "
      4. For those who must work on night work, should be given to the system of care, such as extended paid leave time, regular rotation during the day and so on, to reduce the night shift caused by melatonin secretion caused by cancer or other diseases.
