Clinically, the majority of people receiving hydrotherapy have obtained unexpected health effects, in summary, colon hydrotherapy on human health has the following role: 1, the role of treatment With the increase in the fineness of human eating and the reduction of coarse fiber, as well as the reduction of exercise, social pressure increases, the incidence of constipation is increasing. Constipation not only affects the physiological function of the large intestine itself, so that the secretion of mucus is reduced, and mucus itself has a lubricating effect on the large intestine, the secretion of reduced will aggravate constipation, resulting in a vicious circle. Constipation can also lead to excessive absorption of toxins and affect the function of other organs in the body. A certain course of colon hydrotherapy not only removes dry stool and restores the mucus secretion function of the colon, but also promotes the peristalsis of the colon, thus restoring normal bowel function. Colon hydrotherapy also helps to reduce the generation and increase the discharge of some harmful gases in the colon like hydrogen sulfide, ammonia, methane, etc., thus reducing the discharge of these gases from the respiratory tract and ultimately effectively treating bad breath. 2, preventive effect Food residues in the large intestine through the fermentation and corruption of bacteria can produce some carcinogenic substances, like indole, methylindole, etc.. Due to the different composition of food, the time to pass through the digestive tract is also different. Westerners mainly eat meat, so the food stays in the colon for a long time and the carcinogenic substances produced are also in contact with the colon for a long time, which is the main reason why the incidence of colon cancer in Westerners is significantly higher than that in Chinese people. According to clinical statistics, the incidence of colon cancer and other colon tumors has a tendency to increase gradually. The colon hydrotherapy through the hydrodynamic movement in the colon, the gradual pure warm water on the colon wall for a slow impact, so that intestinal peristalsis enhanced, toxins and carcinogenic substances with water discharge, so as to effectively prevent the occurrence of colorectal cancer. 3.Healthcare role The colon is one of the four important excretory organs of the human body. The alkaline environment in the colon is conducive to the reproduction and growth of bacteria. And bacteria produce many harmful substances and toxins through fermentation and corruption of food residues. Although the absorption function of the large intestine is very small, the accumulation of a large number of harmful substances in the intestine increases the amount of toxins absorbed by the large intestine, thus producing “autointoxication”. Toxins are detoxified in the blood through the liver, which depletes the liver’s detoxification enzyme system. Toxins act on the brain to reduce its excitability and sensitivity, making people easily fatigued, and on the immune system to reduce resistance; at the same time, metabolism is also slowed down by the impact of toxins. In the intestinal hydrotherapy with a large amount of clean water on the intestinal mucosa “soak” to play a dialysis effect, toxin discharge increased, the accumulation of reduced, the body naturally has a sense of relaxation and cleanliness, so the colon hydrotherapy has a whole body health role. 4, the role of beauty The skin is the largest excretory organ of the human body area. The skin and subcutaneous capillaries and a large number of secretion glands will be metabolites and some harmful substances in the blood through the dilated capillary osmosis out of the body. These products in the process of excretion at the same time damage the skin, causing some skin diseases such as pimples, spots, acne, etc., and can cause skin dehydration, dryness, accelerated skin aging and wrinkle formation. Colon hydrotherapy can effectively reduce the production and accumulation of harmful substances, toxins through the intestinal excretion increased, and through the skin excretion reduced, thus greatly reducing the toxins on the skin stimulation, play a very good role in beauty. 5, other roles Colon hydrotherapy can also be used for pre-surgery, and colonoscopy of the intestinal tract preparation. We often encounter some patients in the colonoscopy when there is a large amount of feces in the intestine is not clean, these feces sticky on the intestinal wall not only affect the doctor’s observation and diagnosis of the lesion, but also affect the operation of the doctor, to colonoscopy brings a certain degree of risk, easy to cause intestinal perforation, so patients must do a good job of intestinal preparation before the examination.
