EXERCISE – ENDORPHINS
It has been found that the brain produces chemicals similar to morphine. These are called endorphins. Regular exercise seems to increase the production of these chemicals and produce a feeling of wellbeing. Perhaps you can become hooked on your own endorphins.
But the picture is not all good. Those who are out of condition should begin slowly. Ligaments, joints and muscles become soft and flabby with lack of exercise and too sudden a strain by running on hard ground or doing too much too soon can lead to muscle and ligament strain.
It is recommended that those over 40 or 45 should have a stress test before starting to exercise regularly. This involves having an electrocardiograph during exercise to see if the effort of exercise reveals any evidence of heart abnormalities under stress.
