Fact: After verification, this rumor has no scientific basis. There are many strains of HPV. Although you may be infected with HPV through daily contact, those less harmful HPVs can be eliminated by our immune system. HPV, which can cause genital warts, is almost always transmitted through sexual intercourse.
In addition, the HPV virus itself is relatively fragile and can easily lose activity once it leaves the human body. The temperature of hot spring water is high and it is difficult for viruses to survive. Therefore, it is unfounded to say that hot springs may be infected with HPV and lead to genital warts.

10. Will eating too many cherries cause iron poisoning?
Recently, there is a saying on the Internet: It is best not to eat more than 20 cherries at a time, and you should drink more water after eating. Because cherries contain a lot of iron and a certain amount of cyanogenic glycosides, you cannot eat more. Otherwise there is a risk of “iron poisoning” or “cyanide poisoning”.
Fact: After verification, this rumor has no scientific basis. The iron content of cherries is low. The iron content in 100 grams of cherries is only 0.36 mg, which is much lower than other iron-rich foods (such as red meat, beans, and some green leafy vegetables). . Excessive iron intake through normal diet is very rare. (Scientific refutation of rumors)
