According to a Japanese survey, women who sit for more than 7 hours a day have a 36% increased risk of breast cancer, even if they walk for more than 1 hour a day and exercise more than 3 times a week, they do not change the risk of cancer. Experts recommend that sedentary women should get up and stretch regularly.
Japan's Yomiuri Shimbun reported that a research team composed of Kyoto Prefectural Medical University in Japan released a large-scale survey of Japanese women, and found that sedentary women are prone to breast cancer. Japanese people are considered to be the most sedentary in the world, and women who sit for more than seven hours a day have a 36% increased risk of breast cancer. This article has been published in an international academic journal.
Breast cancer affects 1 in 9 women in Japan, and about 98,000 new breast cancer patients are diagnosed every year. A team consisting of Hitomi Tomita, a researcher at Kyoto Prefectural Medical University, and others analyzed the data from a large-scale survey of about 36,000 people collected from more than 10 research institutes, including universities and cancer centers across Japan.
The research team compared the exercise habits of all people, including 554 breast cancer patients, and showed that women who sat for more than 7 hours a day had an increased risk of breast cancer, and that even walking for more than 1 hour a day and exercising more than 3 times a week, which are thought to be effective, did not change the risk of cancer.
The research team has concluded that once you sit for a long time and do not move your muscles, it is easy to cause sex hormone imbalance and increase the risk of breast cancer. Tomita said that if you notice that you sit for a long time, you will be aware of the need to move your body regularly by getting up and stretching. Kurosumi Ken, an associate professor at the International University of Health and Welfare in Japan, said that this is an article that can make everyone rethink the maintenance of a healthy lifestyle, and he also looks forward to clarifying the mechanism of the association between sedentary and breast cancer.
