Water is the source of life, is indeed the most pertinent to the evaluation of. For the body, participate in life movement, removal of harmful toxins, help the metabolism, maintenance of aerobic respiration and so on, it is precious the one and only universal solvent.
Water's physiological function in the human body Help digestion We eat the food in her mouth, after the teeth chewing and saliva wetting, from the esophagus to the stomach, to complete the digestion and is absorbed by the digestive process, these links are need water to participate in, accelerate the fluid on the nutrient composition of dissolved. The excretion of waste The nutrition of food digestion and absorption of residue remaining waste, through sweating, respiration and excretion of discharge in vitro, these different ways of excretion of water help to achieve. Lubrication of joints Human body joint need water for lubrication to avoid damaging the friction between the bones, while water is the main source of joint lubricant. Equilibrium temperature When the environment temperature below than body temperature, in orders to maintain the body temperature to ensure the normal physiological activity, the body of water due to narrowing of the pores and reduce evaporation and retained in the body. The environment temperature is higher than the body temperature, moisture will pass through the dilated capillaries in the breathing hole to excreted, reducing temperature. Maintenance of cell Water can promote the cell metabolism, maintaining normal cell morphology; keep the skin moist and elastic. To balance the blood Water can improve the blood, tissue fluid circulation, and helps balance blood viscosity and pH. Two special replenishment times Fall ill Constipation should pay special attention to absorb enough moisture, drink plenty of water can stimulate the intestinal peristalsis and softening the stool. When cold or fever, drink plenty of water can promote the body heat. Cystitis patients drink more water than usual, so that the urine volume increase, increased flushing circulation, relieves inflammation. During exercise Long time training will make the body sweat, the plasma volume fall in 16%, timely replenishment can increase in plasma volume, reduce the flow resistance, improves cardiac efficiency and duration of the exercise. During training, the body out of the water should be added timely. Before training about 30 minutes should appropriate replenishment. If the training of thirst can be drinking a small amount of water when rest. For intensive training, in addition to replenish water before training, after training should also be added moisture. As the training intensity, energy consumption much, is to add sugar under 3% the raw juice beverage; hot weather exercise sweat too much, inorganic salt erosion, water should be mainly warm dilute brine; in general the main drink is warm boiling water or mineral water.
