Is it true that urine is sterile?
The natural product of the waste processing system in the body, urine is sterile when it is produced by a healthy body. It loses this sterility after expulsion from the body. The first contamination may come during the urination process when urine lifts bacteria living in epithelial cells that line the urethra. After leaving the body, urine sterility may be endangered by bacteria present in the air and in the collection container. In fact, because the naturally occurring sterile environment practically does not exist as soon as the urine leaves the body, almost immediately loses its sterility. This is the case of urine when it is first produced and is stored in the bladder before the body is excluded. Sometimes it is overlooked that a sterile substance like urine is quite able to support or promote life. In fact, it is attractive to agricultural applications, although it must be diluted before it can be applied safely. The remaining 5% consists mainly of urea, organic substances produced by the body that is helpful in removalProceeding excess nitrogen from the body. Chloride, sodium, potassium and other organic and inorganic compounds and dissolved ions are other substances found in the urine, usually in small amounts.
urine composition can be changed if it is made by a body with a disease or health condition. For example, diabetic urine may contain a significant amount of glucose. I eat some foods or drugs can also have a short -term impact on the appearance of urine, especially its color. However, even in these cases, urine is sterile. The main health status that urine may not be sterile is the urinary tract infection (UTI), where microorganisms can contaminate urine in the bladder and portray it non -sterile.
The question of urine sterility always leads to questions about its suitability to drink. Especially when urine is sterile, it is absolutely safe to drink, especially in limited quantities. Because urine is mainly composed of water and waste products from the body, it has a small, afterWhich at all, a nutritional value. While in emergency situations, urine drinking is an acceptable method of hydration, repeated urine drinking, especially its own, involves returning to the body of the waste products that the body tries to eliminate. This eventually gets excessive kidney loads that are responsible for the processing of waste in the body.
The high water content of the urine can be processed and regenerated as drinking water. Waste processing systems are certified for ESS mammals for this purpose. It is a valuable source in an environment such as a space station where there is no renewable freshwater source. The reclamation project is processed not only by the urine of astronauts, but also by the urine of laboratory animals on board.
