Everyone knows body reactions such as “fart bumps”, stomach aches, hiccups, stomach upsets, yawning, and more. However, most of us do not know what causes them, and they cannot tell who they are connected to.

Many associate a tingling in the stomach with a feeling of hunger, and hiccups are considered by some as a sure sign that someone is missing you! But is it scientific? Let’s find out.


“Goosebumps,” or the feeling that “goosebumps ran away,” appears when we feel cold or have strong feelings, such as fear, ecstasy, or sexual excitement. Pimples form fart bumps due to contraction of muscles at the base of the hair, resulting in hair growth. This type of reaction is found in many mammals except humans.

Responding to cold, the hair gets trapped directly in the air and forms an insulating layer, retaining body heat. However, the presence of “fart bumps” in response to emotional stimuli is more beneficial to animals than humans, because straight hair helps create the impression that the animal looks bigger – as they say, the animal broke. .

Thus, the response acts as a kind of protective mechanism to frighten predators.


Although belching is considered vulgar – it is a completely natural physiological process. When we eat or drink, we usually swallow air, which causes flatulence and stomach discomfort. To relieve such discomfort, swallowed air is removed from the digestive system through the mouth.

Emitted air is mainly a mixture of nitrogen and oxygen. However, in burps made by drinking carbonated drinks, carbon dioxide is contained in the drinks themselves. Other causes of burial may be gastroesophageal reflux (A disorder in which the contents of the stomach enter the esophagus) And gastritis.


Hiccups are involuntary contractions of the diaphragm that simulate a certain breath, however, the sudden closure of the airway by the epiglottis blocks the flow of air, the squeezed sound “ik”, which arises, a rapid closing of the glottis. Is the result of.

Although scientists have not yet reached a final conclusion on the mechanism of hiccups, the most likely causes are sudden changes in temperature, rapid absorption of food, spicy foods, use of carbonated drinks and gastroesophageal reflux. In most cases, the hiccup goes away automatically as the diaphragm relaxes.


What exactly happens when we yawn and why do we yawn? When we yawn, our mouth is wide, which ensures maximum air flow. Inhaled air expands the lungs, constricting the abdominal muscles and pushing the diaphragm down. Then exhale through the mouth.

Several theories have been proposed to explain this reflex respiratory act, but the two theories are the most popular: 1) It is a mechanism for cooling the brain by removing “warm” blood from the brain and “cold” blood from the lungs. Is an introduction to, and 2 this is an exemplary verb – it is worth taking yawning alone, and after that everyone starts yawning, so this action is “contagious”. Yawning is also commonly associated with boredom or fatigue.


This rumming is absolutely inappropriate between an important conversation or during romantic dates. Despite the fact that these visceral sounds sometimes cause feelings of discomfort and embarrassment, they are completely natural and regular. Noise arises due to the contraction of the muscles of the intestinal wall when food and air move through it. The walls shrink to mix food, push it through the intestines and aid digestion.

This process, known as peristalsis, lasts most of the day and is accompanied by rumbling, although in most cases these voices are not heard loudly. Rumble is heard loudly when the stomach is empty, so they are often associated with hunger.
