Health - Laziness leads to heart attack
The effectiveness of exercise in controlling diseases of the heart has always been questioned by some sectors of medicine, which saw them only as a secondary prevention of heart attacks. A more recent study, however, published by New England, placed the exercise as essential in combating disease. The survey studied 3106 adult men in America and considered an inactive high risk factor for the onset of myocardial disease. According to the authors of the study, the risk of death from stroke is 3 times higher for people who appreciate a sedentary lifestyle.
Although conventional wisdom is reflected in the old Roman dictum, "Mens sana in corpore sano" already acknowledged the obvious connection between physical and mental health, the scientific community only recently has drawn attention to the relationship between exercise and brain function. Initially it was thought that the positive effects of exercise were due primarily to the brain''s blood flow increases significantly, so that brain cells are better nourished and oxygenated, and this contributes to making them more healthy. Even being this an important, exercise produces a variety of effects on the brain, which are only now beginning to know, and can not be explained solely by a higher supply of nutrients. For example, not only intellectual activity is important for maintaining the intellectual capacity as you grow older, exercise is too, and still do not understand how. The exercise has proved an excellent method of protection against neurodegenerative diseases, and may even help reduce the impact of these diseases. In this article we address the mechanisms responsible for these beneficial effects, but we must say that I still do not know them in detail.
Basically, the exercise seems to activate a series of processes responsible for maintaining and protecting the nerve cells, which we call physiological neuroprotection systems. If exercise protects the brain from both internal and external aggressions to which they are subjected to throughout life, it is clear that a sedentary lifestyle, very marked in modern societies is a risk factor for neurodegenerative diseases, such devastating in today''s society. The message seems simple: neurodegenerative diseases can be grouped together with the coronary arteries, within the set of diseases in which a sedentary lifestyle is a risk factor.
