What is the effect of physical exercise on health?
Hippocrates, the father of modern medicine said that, all parts of the body if used in moderation develop and age slowly, but if they are left unused they become defective in growth, susceptible to disease and age quickly. Physical exercise and activity is a pre-requisite for a healthy life.
Exercise also confers on the elderly, a sense of purpose and achievement. They come to realise that they have more control over their bodies than they imagined. Exercises have a beneficial effect on the course and severity of many diseases.
The Heart:
Regular exercise can prevent the development of high blood
pressure. Low BP can also be raised. High cholestrol levels
which are a major risk factor in heart attack and stroke
are reduced by regular exercise. Heart attack is more common
in those with sedentary habits.
Diabetes: The
effective treatment of this disease is influenced by the
obesity of an individual. Loss of weight helps prevent and
treat diabetes. Mild diabetes is often controlled by diet
and exercise which is much preferred in the elderly rather
than management by drugs.
Fractures:
As one grows older the bones become weak and brittle, especially
in women after menopause. This and other age related changes
make the elderly prone to falls. Regular physical exercise,
not only increases the muscle tone but also helps the bones
retain calcium and remain strong, reducing the incidence
of fractures.
Cancer: Studies
have shown that cancer of the large intestines is greater
in those who are not physically active. Similarly, breast
cancer and cancer of the sex organs rarely affects sportswomen.
Constipation:
Daily physical exercise combined with a high fibre diet
can help avoid constipation.
Mental Depression:
Exercise increases the blood circulation in all parts of the
body promoting a general sense of well-being. While exercising,
people tend to take their minds off personal and psychological
problems and thus avoid anxiety and depression.
