Why hiccup?

Hiccups (also called hiccups or yoke) can in essence be understood simply as the sudden contraction of muscles used to inhale. As soon as those muscles begin to move, the glottis (the space between the two vocal cords) closes the windpipe to create a characteristic "cough" sound. That is the genuine hiccup.

Explain why people get hiccups

This phenomenon may have existed a long time ago in the early days when humans first appeared. To trace the origins and mechanisms of this natural reaction, scientists have had to delve into the evolution of human history since its formation. According to some French scientists, it is most likely related to the hypothesis, our ancestors used to live in the sea and have gills to support breathing.

For reasons, there are many explanations about this natural reaction of humans. According to modern medicine, lack of water, overeating, hunger for a long time, using cold drinks while eating hot food is the cause of hiccups. Besides, heartburn, eating spicy food, laughing loudly, coughing, drinking too much alcoholic drinks, crying is the cause of hiccups in most ordinary people. Some other cases such as saying a bit too long or lack of electrolyte balance; Use some strong analgesic drugs that contain morphine and Oxycodone; Vitamin deficiency also increases the risk of hiccups.

Around the question why this has so many ideas and scientific theories arises. One theory is that hiccups are preparation for fetal respiratory muscles . In fact, from the womb, ultrasound shows that the fetus is already in the womb before the breathing movement appears. Another theory is that hiccups prevent amniotic fluid from entering the lungs. Most recently, it is said that the hiccup's key lies in a group of animals that, with them, close the glottis combined with the contraction of "inhalation" muscles serve a clear purpose. They are amphibians that have similar respiratory action to the hiccup reaction in the human body such as sharks and frogs .

However, these answers have not brought satisfaction to humans because hiccups appear about 370 years after the animals landed and have not been explained in detail. A group of scientists led by Christian Straus of Paris's Pitie-Saltpetriere Hospital believes that brain circuits that control gill ventilation still exist in modern mammals, including humans as a sign. Digestion of evolution. They point out many similarities between hiccups and gills in gills such as tadpoles. Both hiccups and ventilation are blocked when the lungs swell by high levels of carbon dioxide in water or air. According to them, hiccups are a natural reaction to breast feeding that is gradually formed when people begin to adapt to terrestrial life.

Allan Pack, a specialist in respiratory neuroscience at the University of Pennsylvania, says this is a reasonable theory, but difficult to prove. If this theory is correct, most of the neurons that are active during breastfeeding will also work during hiccups.

Some interesting hiccups : According to the American Cancer Society, more than 30% of patients undergoing chemotherapy underwent hiccups due to the side effects of treatment. Charles Osborne had 68-year hiccups, from 1922 to 1990, recorded in the Guinness Book of Records as the longest hiccup man. In January 2007, Ms. Jennifer Mee in Florida, USA, in her teens also hiccups for 5 weeks, from January 23, 2007 to February 28, 2007. After the hiccup returned, her neurologist was diagnosed with Tourette's syndrome (neurological syndrome causing uncontrollable seizures).

So what do you do when you get hiccups? A few tips, some simple, very effective ways: First, you can take sips of water continuously and cover your nose with your hands, this is extremely effective. Second, you can hold your breath for a while. Third, try to inhale some sugar. These ways are effective for a large number of normal people because their mechanism is actually to prevent regular breathing for a short time so that the diaphragm returns to normal.

In short, really until today, the things people know about hiccups are not really perfect as expected. All explanations of its origin are still hypotheses and there are always unreasonable points. What about you guys, guys?
