Exercise and Health (3)
3. risk reduction for disease
It is experimentally said that moderate exercise helps for the prevention of cancer and infection disease. In 2003, WHO reported about the relation between cancer and exercise. They say with exercise we can certainly reduce the risk of colon cancer and can reduce that of breast cancer with high probability. And they also say that obesity certainly increase the risk of esophagus cancer, colon cancer, rectal cancer, breast cancer after menopausal, uterus cancer, kidney cancer and so on.
We can understand exercise is very effective to our health in terms of obesity and cancer. Except for cancer risk, obesity increases the risk of lifestyle diseases. Japanese people are less resistant to obesity than Westerner. WHO define 30 level of BMI as obesity but the Japanese Society for the study of obesity regard 25 level of BMI as obesity for Japanese. We had better enjoy health effects of sustained exercise including the effect to decrease obesity.
In 2007 national medical expenditures in Japan reached record high 34 trillion Japanese yen and is expected to increase 2% more than previous year in 2008. Without the change of lifestyle for Japanese people, the national cost of medical care is unlimitedly increasing. Health is of course personal matter but also has great impact to national budget. So let each of us does exercise from now!!
