aroused heated discussions among netizens.
So is that the case?↓↓Can sleeping with wet hair cause cancer?
Is it true?
The hot search content comes from a ** report, saying that many people have small red bumps on their scalps, which may be related to sleeping with wet hair. Subsequently, the so-called latest research in the journal Nature was cited to argue that a certain microorganism that breeds wet hair and sleep "increases the risk of cancer". Is this true?
The reporter searched for the article on the official website of the journal Nature and checked the relevant content. The main thrust of the article is that researchers from New York University in the United States have discovered that a large number of fungi originating from intestinal tissue are present in the tumor tissue of pancreatic ductal adenocarcinoma (PDA). For the statement mentioned in ** that "the most common fungus is Malassezia", some of them have started "association" since **.
Medically, Malassezia is a normal parasite on the surface of the human body, which likes to multiply in moist and oily places in the human body, such as the head and back. But the reporter found thatThe hot search content skips the experimental process of **, and directly deduces the conclusion that "sleeping with wet hair causes cancer", and forcibly correlates it through speculation and the way of the title party.
The study did not mention that the Malassezia bacteria in pancreatic cancer came from the scalp. Instead, experiments have deduced that these fungi may come from gut microbesIt has nothing to do with Malassezia on the scalp.
Normally, Malassezia bacteria coexist peacefully with people. Only under certain conditions, such as excessive sebum secretion and decreased resistance, can it easily cause problems such as dandruff, itching, and hair loss. There are also no studies that prove that the tumor growth is related to the fungus on the scalp.
