   [Extra-long work does not pay off] A cross-sectional study in South Korea showed for the first time that excessive working hours are a risk factor for thyroid dysfunction. The Korean National Cancer Center research team selected 2,160 adults. The working hours of the participants ranged from 36 to 83 hours a week. The results found that among people who worked 53 to 83 hours a week, the probability of hypothyroidism increased 2.5 times, reaching 3.5%. For every additional 10 hours of work week, the risk of hypothyroidism increases by 1.5%. Researchers said that hypothyroidism may affect metabolic capacity, cognitive function and mental state, and reduce work efficiency, so long hours of work outweigh the gains.
   [Sleeping 7 hours a day can best protect the kidney] The latest study by West China Hospital of Sichuan University shows that the relationship between sleep time and chronic kidney disease or proteinuria has a “U” curve. Sleeping too long or too short can increase the risk of chronic kidney disease and proteinuria, and sleep 7 hours a night has the lowest risk. This study analyzed a total of 521,242 participants in 11 observational studies. Studies have shown that sleep ≤ 6 hours and ≥ 8 hours a night will increase the risk of chronic kidney disease by 13% and 14%, and increase the risk of proteinuria by 24% and 15%.
  [Aspirin can reduce the risk of gastrointestinal cancer] A new Italian study found that taking aspirin regularly can reduce the risk of gastrointestinal cancer by 22% to 38%, including some fatal cancers such as pancreatic cancer and liver cancer. Epidemiologists at the Faculty of Medicine of the University of Milan, Italy reviewed the data of 113 observational studies. The analysis found that taking aspirin regularly (defined as taking at least 1 to 2 tablets per week) reduced the risk of bowel cancer by 27% and lowered the risk of esophageal cancer. 33%, the risk of cardia cancer was reduced by 39%, the risk of gastric cancer was reduced by 36%, the risk of liver cancer was reduced by 38%, and the risk of pancreatic cancer was reduced by 22%.
   [People who love money are more likely to be lonely]A recent study by American psychologists pointed out that loneliness is one of the main causes of depression and anxiety. In modern society, money-oriented and interest-centered values ​​are more likely to cause loneliness. The research team sorted out 5 psychological studies involving more than 2500 people. Researchers conducted an in-depth analysis of the correlation between money, self-worth, time spent with others, and loneliness. The results show that the higher the position of money in the self-worth evaluation criteria, the stronger the psychosocial disconnection and loneliness. In contrast, people who “see money as dung” may be more likely to gain a sense of health and security.
   [Screen exposure does not damage children’s social skills] A new study from Ohio State University found that there is no evidence that long exposure to the screen will affect the development of children’s social skills. The researchers compared children who entered kindergarten in 1998 and children who entered kindergarten in 2010 and found that from the teacher’s point of view, the two groups of children did not have poor social skills after enrollment, and the 2010 group scored higher in social skills. Even the children in the two groups who touched the screen the most had similar developments in social skills compared to the children who did not touch the screen.
  [Adriamycin is expected to overcome leukemia drug resistance] Adriamycin, a chemotherapy drug that can treat a variety of cancers, has recently been found to have new uses. A new study in “Nature Cell Biology” shows that low-dose doxorubicin may overcome leukemia drug resistance, inhibit leukemia stem cells, and expose them to an activated immune response.
   [Intestinal probiotics have anti-influenza effects] The latest research of Huazhong Agricultural University stated that specific intestinal probiotics can significantly enhance the anti-influenza effect. Researchers found that transplanting the fecal intestinal flora of mice surviving influenza infection to healthy mice can significantly improve the latter’s resistance to influenza viruses, indicating that certain intestinal bacteria in surviving mice can increase The tolerance of the host to influenza infection.
   [Drinking coffee may change genetic activity]A new study in the Netherlands shows that the more coffee cups a person drinks a day, the more likely they are to change the methyl levels in 11 specific DNA types. This is still the case after considering age, body mass index, smoking, drinking, and other factors that may affect the results. In other words, drinking coffee may change the expression of some of our genes, which helps explain the health benefits of drinking coffee.
   [Video sharing can improve parents’ happiness] Recently, a remote meal sharing experiment from Tokyo Denki University in Japan found that sharing meals can improve the physical and mental health of the elderly and prolong their lives.
