Modern women work and live under great pressure and have diversified entertainment, so they often sleep late, stay up late, and even turn black and white upside down. This bad lifestyle will make people easily strain, immune function will be affected, body organs will be damaged, and the chance of tumor will increase. Recently, a study published in the journal “European Cancer” pointed out that women who often sleep late, stay up late and live irregularly have 1.5 times more tumor lesions than healthy women. If women stay up late often, it will lead to endocrine imbalance and hormone imbalance, which will lead to uterine fibroids and breast lesions. Harvard Medical School and Brigham and Women’s Hospital in Boston jointly conducted a survey in this regard. The researchers pointed out that the nightlife is too frequent, which will make women exposed to light for a long time, the normal secretion of melatonin in the body will also be affected, the body’s vital rhythm is disturbed, the neuroendocrine system dysfunction, estrogen, progesterone imbalance, which may lead to the occurrence of fibroids, endometrium and mammary gland lesions. In this regard, our relevant experts also said that irregular work and rest will indeed increase the chances of developing certain gynecological tumors. “In fact, staying up late is not only harmful to women only, but men are also equally threatened.” Dr. Cao Zeyi, a leader in obstetrics and gynecology in China, pointed out that if bad work and rest is not corrected and treated for a long time, it is likely that organic lesions of reproductive organs, even including various tumors, such as uterine tumors and ovarian tumors, will occur. Women often stay up late to suffer from uterine fibroids, however, Dr. Cao also pointed out that “staying up late does not absolutely cause gynecological tumors.” Like some long-term night shift workers, who have adapted to night work and do not experience strain and poor spirit after the night shift, there is no need to worry too much. He said that it is better for women to go to bed early and get up early in their daily life, to work and rest regularly, to ensure enough sleep, and try not to stay up late to watch TV, surf the Internet or participate in entertainment activities that are easy to make people excited. If you need to work night shifts or shifts because of work, you should adjust in time, rest more after the night shift, and supplement sleep in time during the day. Therefore, women should recognize the causes of uterine fibroids, and must develop a healthy lifestyle, do not smoke, do not drink alcohol, avoid unsafe sex, strengthen physical exercise, and maintain mental health. Married women are better off having regular annual checkups to get early diagnosis and treatment for gynecological diseases.
