At least once in a life each person had a hiccup, therefore, that this such is visually has representation everyone. This process is naturally not the most pleasant, sometimes you can say it even annoys. Recently, scientists have seriously wondered why a person hiccups, and also why people sneeze and yawn. A number of studies were carried out on this subject, and the conclusions of the scientists turned out to be rather unexpected. As it turned out, hiccoughing, yawning and sneezing are very useful things for the human body.

Causes of hiccups
From the scientific point of view, it has long been proven that hiccups are a direct process during which the body wants to get rid of the load from the so-called vagus nerve, to release it from excessive activity.
This nerve, in turn, connects the central nervous system with many internal organs of a person. It directly passes from the chest to the abdominal, and at the same time it closely adjoins the esophagus. Together with the esophagus it passes through a small hole, which is present in the diaphragm - the septum, which in turn separates the abdominal cavity from the thoracic cavity, consisting directly of muscles and tendons.
Just exactly this place, a narrow hole in the diaphragm, and is considered the center of the birth of hiccups. In those cases when a person quickly eat and swallow large chunks of food, while almost without chewing it, they get into the esophagus and traumatize, thus, that same vagus nerve, and he, in turn, is irritated and pressed. It should be noted that this nerve can be injured in case of overeating, fright, when the body is in an uncomfortable position, and also from the cold( this process is quite often seen in infants).
Here at such times the body feels uncomfortable and tries to lose excess weight from itself and as a result the person begins to hiccup. Treatment of such processes directly produces the body independently, with the help of hiccups. Since the compression of the nerve can be detrimental to the functionality of many internal organs, our body immediately responds by sending a signal to the central nervous system, and it already uses the diaphragmatic nerve, which is responsible for the contraction of the diaphragm.
As a result, it turns out that the diaphragm nerve creates a pulsating activity, due to which the aperture is shortened, while doing it it is powerful and sharp movements. It is this process that is called hiccough, which can also be accompanied by a sound that appears as a result of a sharp closing of the glottis. In addition, hiccups are an involuntary reflex, which a person, unfortunately, can not control.
In the event that you can not stop hiccoughing for a long time, or hiccups occur frequently, then you should consult a doctor. Since hiccups can be a sign that you have some kind of frustration, both mental and physiological. For example, hiccups can warn you about what you have, or there may be a myocardial infarction, gastritis, various kinds of esophagus, neck tumors in the future. Therefore, if you think that the hiccup is abnormal, then consult a doctor, it will not be superfluous.
How to get rid of hiccups?
In order to get rid of hiccups there are several ways, namely: you need to stretch, take a deep breath a couple of times, or hold your breath on a sigh, you can still drink a small amount of water in small sips. These methods are the most effective in combating hiccoughs.
Why do we yawn?
Yawning as such is a rather complex and poorly understood phenomenon. For today it is proved that yawning is directly related to fatigue or lack of sleep. Yawn can also be a person who does not want to sleep, not tired, and not bored. It should be noted that almost all animals yawn also. But the babies begin to yawn in the womb of the mother.
Quite often a person begins to yawn, being in a stressful situation. Yawning gives the brain a rest, some relaxation, the airways expand and the body starts to get more oxygen than during normal breathing.
In addition, people can also yawn in a room that is poorly ventilated, in a warm room where there is a low concentration of oxygen.
Yawning helps to relieve psychological stress and stress, and also helps prevent many diseases. Therefore, to fight with a yawn, you can not rush.
It is also worth noting that in a number of studies, a group of scientists from the University of Binghamton, established another reason for yawning. So, this cause is overheating of the brain.
After conducting research on a group of wavy parrots, they came to the conclusion that in the case when the human brain "boils up", soon the person should yawn. Such a physiological act will be equivalent to the beginning of the work of the fan, which cools the overheated computer processor.
The best working capacity of the brain occurs in a cooled state, and yawning is in turn a physiological adaptation in order to cool the brain as much as possible.
As a result, it became clear why people yawn before and after sleep, since the brain needs a kind of shake, resulting in yawning sometimes becoming a symptom of the disease. It immediately became apparent why yawning occurs as a result of cooling the forehead or rapid breathing through the nose.
Yawn is commonly associated with fatigue. For example, a person is tired and wants to sleep, in such conditions, the temperature of the brain and the blood flowing through it directly increases. In the case when the air that surrounds the body, the person's face is cool, then the yawn can replace the deep breath and exhale, which in turn will help cool the blood that flows to the face, and that will cool the brain.
It is also worth noting that frequent yawning can be one of the symptoms of multiple sclerosis, including pre-epileptic seizures, and in people who suffer from migraine. The problem with temperature regulation in the brain can be evidenced by an obsessive yawning. This, in turn, means that doctors should more closely monitor the patient who complains of frequent bouts of unreasonable yawning.
Why do we sneeze?
Sneezing is much easier. In the professional sphere, sneezing is commonly referred to as sneezing reflex, which is present not only in humans, but practically in all animal species.
So, people sneeze in order to remove from the nose the smallest particles of various substances that cause difficulty in breathing and irritation of the nasal mucosa.
Due to sneezing, the sinuses and nose are cleansed, and body cells are enriched with oxygen.
If the process of sneezing is considered in stages, it will be obvious that first the person feels some tickling in the nose, which in turn is caused by the ingress of any irritant of the mucous membrane( dust, particles of perfume, pollen, etc.) into it. After that, the brain gives the signal to get rid of this stimulus, the person begins to inhale deeply, and as a result, makes a powerful and sharp exhalation through the nose.
Simultaneously, the tongue begins to cling to the sky and the air, thus, ceases to enter the lungs into the oral cavity. Further, air flies through the nasopharynx, at a distance of up to three meters and at a speed of about 120-130 m / s. In the period of sneezing, an incredible strain passes through the body.
After that the airways are cleaned, and the person can again breathe freely.
In the case when you sneeze quite often at home or in your office, it means that the room needs to be ventilated as often as possible. It may also be possible that there is an allergen or irritant nearby, which is the cause of sneezing.
As you have noticed, hiccoughing, sneezing and yawning, the processes are physiological, and are aimed only at beneficial action.
