In the summer, people in the city know that they need to take a shower to cool down, but not many people know that they need to take a shower for their buttocks; many people know that they need to wash their faces, rinse their mouths and brush their teeth to maintain oral hygiene, but very few people give their buttocks a shower to clean their anus and keep it clean and hygienic after defecating. In fact, from the hygiene point of view, “disease enters from the mouth and comes out from the mouth”, the anus is the “transfer station” for human waste, the dirtiest place in the body, and the place with the most opportunities for infection with bacteria and viruses. Chinese people only pay attention to washing their hands before meals and rinsing their mouths after meals, only paying attention to “entrance hygiene”, but not to cleaning the anus after pooping, not paying attention to “exit hygiene”, which is also the cause of “nine out of ten hemorrhoids”! The incidence of hemorrhoids is a major reason for the significant increase in the incidence of hemorrhoids. The actual fact that the buttocks, the anus is a private part of the body, in order to avoid “going naked” in the summer is often packed very tightly, impermeable, not breathable, plus the anal skin is rich in fat, sweat glands and sebaceous glands, summer heat and humidity will keep secreting sweat, oil. According to the survey, in the unclean anus, each cubic centimeter is densely covered with millions of bacteria, after defecation, each anal wrinkles are latent tens of millions of bacteria and viruses and parasitic eggs. After defecation, it is impossible to wipe clean with paper towels alone, because there are many longitudinal wrinkles of varying length and size around the anus, and forceful wiping will make the stool and fecal residue remain in the depths, and vigorous friction will damage the anal mucosa and cause inflammation. If you don’t pay attention to cleaning after the stool, it is easy to hide dirt, causing infection resulting in anal pain, bleeding, and hemorrhoids. In fact, it is very simple to keep the anus clean and hygienic, that is, first full body bath, shower, and then local rinse buttocks, cleaning the anus, because the fecal residue, residue is very easy to be dissolved by water and rinsed off, every day when the shower, with warm water shower head, faucet aimed at the anus rinse a few times, and wipe clean, that is to complete the cleaning work, time-saving and simple, easy to adhere to and promote. If you can use warm water to sit in the bath for a while after the shower, the effect is better. You can prepare a plastic basin that can put your buttocks completely into, put in warm water, put your buttocks into it, soak or clean the anus with your fingers or skimmed gauze to promote blood circulation, reduce bruising in the buttocks, and reduce anal pressure and tension. This method cleans the anus, first using warm water to dilate the surrounding blood vessels, causing the anal wrinkles to relax and expand and the residual fecal residue to dissolve in water and discharge, and then cooling it down to contract the local capillaries and eliminate the fecal residue and residual fluid, making the anus clean, shrinking the hemorrhoid nucleus and reducing the bruising in the buttocks, effectively reducing the congestion and pain of hemorrhoids.
