People with had health customs or habits have a much greater chance of suffering serious diseases and needing costly medical care, but good habits, such as a program or physical exercise, appear to protect health.
The most of the patients who were in the hospital for a long time and who faced high medical costs were persons who were overweight, who smoked heavily, or who drank too much alcohol. Persons with such bad habits faced at least a 50 percent greater than normal chance of needing costly hospital care. The smokers usually had lung or blood vessel disease. The heavy drinkers had liver or nerve disease. And those who were overweight had heart disease, or diabetes (糖尿病).
A program of physical exercise improves the body’s ability to dissolve or melt dangerous blockages in blood vessels. Such a blockage or blood clot in vessels carrying blood to the heart can cause a heart attack.
The researchers tested 69 persons, both before and after the persons had taken part in a ten- week physical exercise program. The program involved a great deal of physical efforts tretching, walking and running. The scientists found that there was a large increase in each person’s production of clotdissolving (血块溶解) substances after the ten-week exercise program. This was true even in those persons who did not change other habits that increased the dangers of heart attack, such as cigarette smoking.
So we said the study is more evident than physical exercise that can help protect the person’s health. Good physical condition can reduce the chances that a person will die from heart or blood vessel diseases.
