The film may be fake! Menstrual blood does not attract sharks

For a long time in history, humans have misunderstood the female menstrual cycle. Decades ago, NASA provided 100 tampons to female astronauts for a week-long mission. So in different places or environments, I believe many girls have asked themselves this question: Will it be easy for my aunt to go surfing or diving to attract sharks?

The surfer Laird Hamilton ( Laird Hamilton, he told the audience Thanks to the program, "shark attacks" are very rare in reality. In fact, most shark attacks on humans are not caused by blood , but by bad actions of humans in the ocean The average menstrual flow of a woman is around 30-40 ml of blood in a few days, with the maximum amount being around 80 ml, reaching a very heavy cycle. Basically, if you suddenly had an excess period and drained all the blood from one neck.p, you would throw about 6 tablespoons of blood into the ocean. Due to the extreme sensitivity of these cells and the special state of their brain, sharks can detect many traces of chemicals. It's amazing that a great white shark can detect a drop of blood in about 100 liters of water, or 1/25,000 the amount of water in an Olympic-sized swimming pool. What sharks want to smell is the blood and amino acids of marine animals, which are very attractive to sharks.

But relatively speaking, our human blood, sweat, tears, urine, etc. are just a taste that you don't particularly expect, and won't make you think of normal sharks "eating". In 2016, Steve Caguiro of the Shark Lab at Florida Atlantic University gave his opinion. He points out that even if sharks could smell human blood, they wouldn't immediately consider it a tasty dinner. Additionally, Chris Lowe, searchstudy on sharks at California Long Beach State University, responded to Hamilton's comments in the Huffington Post by saying: "That's one of the misconceptions about death denial." In fact, during menstruation, the amount of blood lost may not be as much as a scratch or cut from a child or a surfer playing in the water. » But one thing is that sharks are generally known to be sensitive to blood. The sole purpose of a shark's nostrils is to smell food, not to breathe. They are very sensitive to blood. But sometimes blood doesn't even matter because they detect amino acids from blood in water, which are the building blocks of proteins found in all of our bodily fluids. What they want to detect are the amino acids present in the blood, intestines and soil of marine animals. Menstrual blood is not just blood, it also contains cervical mucus from youruterus and other secretions are completely normal. And if you go swimming during your period, there will only be tiny traces of blood left in the water. In other words, to put it simply, when they feel our fresh blood flowing from our blood vessels, they will treat it like a delicacy, but menstrual blood will treat it like leftovers in the trash. In such a simple way, you should do it. understand it!

Professionals emphasize that the best way to avoid shark attacks is to maintain good swimming posture.and breathe regularly, don't let the shark treat you as "weak prey" or "easy ". However, in any case, it is best to play in places where sharks are present under the guidance of professionals. This is the best guarantee.
