A study in the UK showed that about 1% of cancer patients or about 3,400 new cancer cases each year are associated with not meeting the government’s recommended activity levels. Rectal cancer 15% Residents of developed countries, who have a lifetime probability of developing rectal cancer of about 0.2%, will have a 15% higher risk of developing rectal cancer if they are physically inactive compared to those who exercise regularly. Stomach cancer 28% Residents of developed countries are about 1.2% more likely to develop stomach cancer during their lifetime, and if they are physically inactive, they have a 28% higher risk of developing stomach cancer compared to those who exercise regularly. Colon Cancer 19% Residents of developed countries are about 8.6 % more likely to develop colon cancer during their lifetime, and if they are physically inactive, the risk of colon cancer increases by 19% compared to those who exercise regularly. Lack of activity is also one of the main risks for cancer. Lack of activity not only leads to weight gain, but also has a negative impact on the body’s immune and endocrine systems. A 2011 study in the U.K. showed that about 1 percent of cancer patients or about 3,400 new cancer cases each year were associated with not meeting the government’s recommended activity level. According to Cancer Research UK, people who are active are less likely to have polyps (adenomas) in their intestines, which grow in the lining of the intestines and can develop into cancer. The benefits of physical activity are, firstly, that it helps the body to defecate normally, so that the carcinogenic substances in undigested food stay in the intestine for a shorter period of time; secondly, physical activity can reduce the levels of insulin, certain hormones and growth factors, which, at high levels, can promote the growth of tumors. In addition, physical activity can change the level of “prostaglandins”, which are active substances with various physiological effects and are found in both men and women, and can be secreted by the kidneys, stomach and intestines. Suppressing prostaglandin levels can reduce inflammation in the intestinal tract, thereby slowing the rate of cell reproduction and growth and reducing the potential for cancer in cell replication. Uterine Cancer Endometrial Cancer 27% Women in developed countries are about 2.0 % more likely to develop endometrial cancer during their lifetimes, and if they are physically inactive, they have a 27% higher risk of developing endometrial cancer compared to those who exercise regularly. The results of several studies have shown that increased physical activity in women can reduce the risk of breast cancer. Researchers have also found that regardless of weight and waist circumference, women who maintain a certain amount of physical activity after menopause can reduce their risk of breast cancer by 10 percent. Whether it’s physical labor, recreational physical activity, housework or cleaning the house, the risk of breast cancer can be reduced. Studies of European women, including the European Committee for Investigation into Cancer and Health Development (EPIC), have shown that daily activity can reduce the risk of breast cancer. Physical activity can reduce the risk of breast cancer by lowering levels of insulin, certain hormones and growth factors. In addition, physical activity can reduce the level of estrogen in the blood and serum insulin levels, thus reducing the risk of uterine cancer. Depression Optimism Index 213% Residents of developed countries who lack physical activity have a 213% higher risk of having a low optimism index. Happiness Index 52% Residents of developed countries who are physically inactive have a 52% higher risk of having a low happiness index. Depression 150% Residents of developed countries who are physically inactive have a 150% higher risk of depression. Anxiety 38% Residents of developed countries who lack physical activity have a 38% higher risk of developing anxiety. Often, when we feel anxious or depressed, we would rather stay on the couch than get out and do some exercise, but here’s what the experts suggest: exercise can help you eliminate these negative feelings. The Mayo Medical Center in the United States gives guidance: exercise helps prevent and improve many health problems, including high blood pressure, diabetes, etc. Studies on anxiety and depression have also shown that exercise can help reduce anxiety as well as improve mood. While researchers haven’t quite figured out the exact link between anxiety, depression and exercise, exercise can definitely help alleviate symptoms of anxiety or depression, make people feel better and prevent bad moods from coming back to haunt them. Regular exercise can help alleviate depression in several ways: by releasing brain chemicals that make people “feel good” and alleviate depressive symptoms (neurotransmitters, endorphins and endocannabinoids), by lowering immune system chemicals that exacerbate depression, and by raising body temperature, which may have a calming effect (sedation). Exercise is distracting and can keep people away from negative thoughts, preventing the vicious cycle of anxiety and depression. In addition, we have the potential to meet other people during exercise, even if we just brush past them and say hello, it is beneficial to improve our mood. Some studies have shown that even walking is beneficial to improving mood. Although physical activity and exercise are not the same concept, they are both beneficial to our health. Researchers concluded that any activity that gets people off the couch is good for mood. Alzheimer’s disease Alzheimer’s disease (dementia) 82% Residents of developed countries, who are about 13% more likely to develop Alzheimer’s disease during their lifetimes, have an 82% higher risk of developing Alzheimer’s disease if they are physically inactive compared to those who exercise regularly. Parkinson’s disease 22% Typically, residents of developed countries are about 1.7 % more likely to develop Parkinson’s disease during their lifetime, and if they are physically inactive, the risk of developing Parkinson’s disease increases by about 22% The 2015 Global Alzheimer’s Report shows that by 2050, the number of people around the world with Alzheimer’s disease will more than triple from the current 47 million to 132 million people. In 2015 alone, there were about 10 million new cases of Alzheimer’s disease, which equates to about 19 people developing Alzheimer’s disease every minute. A study of 1,200 Swedish adults followed for 21 years showed that moderate-intensity physical activity at least twice a week in middle age was associated with a 53% and 65% reduction in all-factor dementia and Alzheimer’s disease, respectively. Another study showed that in a study of 803 Japanese seniors living in suburban areas, those who were physically active at least one day a week had a 41% lower risk of developing Alzheimer’s disease (excluding other types of dementia) over the next 12 years compared to those who were less active. Other studies on the elderly have also shown that any form of physical activity reduces the odds of developing Alzheimer’s disease, or dementia mortality, compared to a sedentary lifestyle. Other studies have shown that the reason for dementia in the elderly is related to various poor lifestyles such as inactivity, obesity, and smoking. Among them, lack of exercise is the most important cause of dementia. Regular exercise can effectively prevent dementia because it ensures the blood supply to the brain and prevents the formation of blood clots.
