Collect everyone's curious brain knowledge, and organize valuable learning materials for the reference of friends who have been on the road to learning.With the high incidence of cancer, people's awareness of maintenance is gradually increasing. Tobacco, alcohol, and radiation are particularly cancer-causing factors, but few people think of "black and white upside down".
We often hear people say that "staying up late causes cancer", and we often hear many people in the news advising others to "never stay up late".
In February 2024, the Journal of Hepatology published a study on the causes of cancer caused by staying up late for the first time, proving that black and white reversal (chronic circadian rhythm disorder) is indeed a human carcinogen.
Circadian rhythm disorder, in fact, is the familiar reversal of the biological clock, the human body will automatically synchronize with the earth's diurnal cycle, the brain originally set an internal clock for 24 hours, when our body's internal clock is out of balance, cancer and many other diseases will follow.
The research team conducted experiments on mice with similar rhythms to human bodies, and found that once the tumor develops spontaneously when the black and white are reversed, the tumor development slows down and inhibits the metastasis of the tumor when the body returns to a normal circadian rhythm. The whole body has entered a virtuous circle again.
In July 2023, a research team from Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, published a study on sleep habits, cancer risk and timing in the well-known journal CancerAn analysis of 50,000 people concluded that too little sleep was strongly associated with an increased risk of cancer. Therefore, in addition to the reversal of black and white, sleep habits are also prone to cancer.
People who slept less than 6 hours had a 41% increased risk of cancer. The risk for women in particular can be as high as 53%.
People who don't take a nap also have a significantly higher risk of cancer. People who never take a nap have a 60% higher risk of cancer than those who take naps for more than an hour.
People who don't take naps and get short nights of sleep have a higher risk of cancer. People who slept less than 6 hours at night and never took a nap had an 82 percent higher risk of cancer compared to participants who slept about 6 to 8 hours at night and took naps for more than one hour.
Experts recommend 8 things not to do:
1. Don't go to bed too lateBetween 11 p.m. and 3 a.m. is the best time to get into a deep sleep, and if you miss it, it will be difficult to make up for it no matter how long you sleep.
2. Keep quiet before going to bed and avoid strenuous exerciseIf you do a lot of exercise at night, it will make the brain in a state of excitement and secrete related hormones, so that you can't fall asleep with excitement, so exercise should be placed during the day to achieve a healthy purpose, thereby changing the quality of sleep.
3. Don't eat too much before going to bedIf you eat too much before going to bed, it will cause your blood sugar to rise, which will also make people in a state of excitement and not easy to fall asleep.
4. Reduce the number of excessive talking before going to bedIf you talk a lot before going to bed, your brain will be in a state of excitement, and it will be difficult for people with active thinking to fall asleep.
5. Don't play with your phone before going to bedPlaying with your mobile phone before going to bed will make you unconsciously spend a long time in bed, but you can't fall asleep, and after putting down your mobile phone, there are still many people in a state of excitement, which leads to difficulty sleeping.
6. Don't overuse your brain before going to bedThinking too much about problems before going to bed will put the brain in a state of excitement, and there is no way to fall asleep after lying down.
7. Don't drink coffee and strong tea before going to bedCoffee and strong tea are best scheduled to be drunk three or four hours before bedtime, and drinking these drinks containing hyperactive factors before going to bed is not conducive to sleep.
8. Maintain a stable mood before going to bedBecause people's joys, sorrows, and sorrows are prone to cause disorders in the nerve center, it is difficult to fall asleep. So try not to get into arguments with family and friends before going to bed, and don't put yourself in a state of joy and anger.
