Maintaining formal Excretions of the Body
FU QINGJI
THE body gets rid of harmful waste substances through exhalation, perspiration, urination and defecation. Main¬taining normal excretion is an important factor in health and longevity. It is often neglected.
Defecation should take place once every day, though once every other day is also normal. Once every three days is abnor¬mal. Constipation is especially harmful to people with hypertension, coronary heart disease, and hemorrhage of the ali¬mentary canal. Without timely defecation the harmful substances are reabsorbed, a kind of self-poisoning. The longer excrement stays in the colon, the more harmful substances are reabsorbed into the body. This not only harms the organs but irritates the colon and rectum, causing inflammation and some¬times cancer. So we should cultivate the habit of defecating once a day. When constipation occurs, go to doctors and adjust the diet. Eat more vegetables that contain cellulose, such as celery and chives. Add sesame residue and honey. Eat more fruit.
Urinate when urged, never try to hold it. Some harmful substances are discharged through the urine such as creatinine and urea nitrogen. Delayed urination increases the pressure on the bladder, hinders the excretion of urine from the kidney and obstructs the discharge of harmful substances. Long time reten¬tion will cause infections of the urinary organs, especially in women, whose urethra is shorter than men. Drinking more
water is helpful.
When quiet, a human excretes 800 to 1,500 ml. of water a day through perspiration and exhalation, even though there is no sweat on the skin. Obstacles in these two processes directly harm health. Thus we must protect the skin and maintain its normal functions. We should take a bath often, prevent and treat skin diseases, wear soft garments to keep the body warm in winter, and absorbent clothes with good air permeability in summer. Do exercises regularly to increase vital capacity, keep good ventilation in the room, and have more outdoor activities.
In short, to keep fit, in addition to good nutrition, main¬taining normal excretion is very important.
