Burping

Belching (also burp ( do ), Bolken, eruktieren, burp, belch, medical eructations, Efflation or eructation ) is the noisy belching of air from the upper digestive tract (mainly esophagus and stomach) through the mouth. Based on the typical sounds are the various onomatopoeic names.

Physiology

Burping is often caused by drinking or eating too fast, often air is swallowed with ( aerophagia ). Likewise, the process can also be set by deliberately swallowing of air in motion. Can also belch when drinking carbonated beverages follow (mineral water, beer, soft drinks, sparkling wine). In this case, the carbon dioxide gas be discharged. Gastroesophageal reflux disease can cause involuntary burping.

Social importance and etiquette

In the Western world (especially the audible ) burping is considered impolite. However, it is not equally frowned upon as farting. Willfully, it is quite possible noiseless push open. Some people hold in particular at the table while the hand like when yawning in front of the mouth. Previously, the habits were different, it was even appropriate to belch, to prevent abdominal discomfort, and Knight waived no attention. Martin Luther is the saying " What rülpset and not furzet it, it has not geschmacket you? " Falsely attributed. Since burping is widely regarded as vulgar and uncultivated in the Western world, it is often used demonstratively, to provoke and to celebrate transgressions against prevailing norms, as among teenagers.

In China, unlike for example in neighboring Japan, burping is not frowned upon and is perceived as a natural background noise while eating and drinking as well as slurping and smacking. However, burping is not a sign of special favor rests. So there is no reason to distinguish himself by excessive, intendiertes burping.

Burping of babies

In the digestive tract of babies are often collected during the food intake a lot of gas. This can be uncomfortable for the child until it " makes a burp ", ie burps. To this end, the baby is often placed in a position conducive to the gas emissions, set about over the shoulder of an adult and gently patting or massaging the lower back. Because burping can cause vomiting in infants, a towel or an old piece of clothing is often (often referred to as a burp cloth ) placed over the shoulder of the adult. In the English language this garment is called burp cloth, which can be roughly translated with Rülpstuch.

Gerülpstes Talk

It is possible to belch at will by the deliberate depression of air and then pushing or pressing Up. By manipulating the flow of air in the throat can occur " gerülpstes Talk ". This method is primarily used by children in a humorous way. It can also mean an alternative speech generation for people who have undergone a laryngectomy. In this case, it is the mucosa of the esophagus at the level of the upper sphincter muscle (sphincter ), which is rotated by the air to vibrate. In this way, it replaces the vocal cords (replacement Timm crack ). It creates a sound that is shaped corresponding to a volume in the oral cavity. This spare part is also known by the professional not entirely correct term " Ruktussprache ".

In Mayan Shamanism

In shamanistic rituals of the Maya - Tzotzil Indians ( chickens) are transmitted through belching demons in sacrificial animals. The ceremonies take every day in the cath. Parish Church of San Juan (Johann Baptist ) located in the Chiapas village instead of Chamula.

In animals

Eructation is the belching especially in ruminants, such as cattle, sheep, goats. The main part of the discharged gas mixture is set methane, which is a byproduct of the animal digestion. Anaerobes, such as Escherichia coli ( E. coli) and methanogenic microorganisms are responsible for the methane emissions in animals. A cow is a daily average of between 540 liters ( in the barn ) and 600 liters from ( in open field ) to the environment. This happens mainly in cattle by flatulence and belching.

Some Australian scientists are trying in Perth to develop a vaccine antimethanogenic to minimize emissions of the greenhouse gas methane by cattle.

Some fish (such as Carangidae ) push gas from beneath their gills. The " burp " in this case comes from gas in their swim bladder. Other animals such as horses or rats are not able to burp or vomit.

World Records

The current world record for the loudest ( recorded on tape) belching was drawn up by England's Paul Hunn from London. We measured 118.1 decibels. This is louder than a chain saw.
