10 Reasons Why People Are So Scared

Have you ever wondered why we humans are so … rude? We laugh, smell bad, we vomit – we always do disgusting things.

We are, indeed, cruel, but we are so with the aim of surviving! Exploring the “science of grossness” can help us understand why we have warts, why we pull winds and why our bodies smell bad.

In this article, we invite you to explore a perfectly normal side of the human body, this biochemical machine whose fundamental functions can sometimes put us in embarrassing social situations.

Why are we screaming?

Everyone screamed. Whether you scream discreetly after you get up from the table or make a loud noise, you should know that everyone – without exception – is screaming.

Gases, primarily carbon dioxide (although other gases such as hydrogen and methane can accumulate) are slowly gathering in our stomach. This gas can be inhaled when you drink or eat, or it can be found in the food you consume, such as carbon dioxide in carbonated beverages.

The gas is retained in the stomach by the esophagus sphincter. As the gas continues to accumulate, it is increasingly difficult for the esophagus sphincter to keep it in place.

The gas has to come out to ease the pressure in the stomach. So when the gas gathers enough, it opens the esophagus sphincter, which results in screaming (eructation).

And anyone who has ever stalked (that is, all of us) knows the relief we feel when stomach pressure disappears.

Defeat, of course …

Fickling, one of the rough aspects of the human condition (though, of course, is not an exclusive attribute of our species), is essential. It helps you remove bacteria and non-digested food from the body, as well as other residues.

Removal of residues is a very important process for humans. But defecation may have an even greater purpose: excrement can be an indicator of your health.

The appearance of its faeces and the difficulties in the act of defecation may be strong signals that something is wrong. The abnormal seat may indicate an infection, digestive problems and other complications.

Why do we sneeze?

The sneeze is another noisy manifestation that some societies consider rude. But the sneezing helps unwanted invaders not reach your body through the airways.

Irritants (such as pepper or dust) that get into your nose can be quickly removed by sneezing. The sneeze can reach the speed of 160 kilometers per hour.

This reaction also occurs when nose membranes are infected with a virus, such as a common cold. Your sister keeps your nose free of bacteria and harmful viruses.

That’s why sneezing is a vital function for your health.

The stomach

There’s always something in your stomach. Whether he is trying to tell you that it’s time to eat, tells you that it’s too full or that it sucks for other reasons, your stomach is never quiet.

And, even if it’s loud, your stomach has some very important functions. By producing specific mucus, acids and enzymes, the stomach helps your body digest food and extract useful nutrients.

In addition, the stomach stores food, which allows you to stay fit between two meals.

Why do we have mucus?

Mucus (the “muci” popular) is just one of the rude products of people, the products we deal with every day

Your nose is flowing and you get stuck with it. Some people clean their nose and sneezes everywhere. Not surprisingly, secretion of mucus is less pleasant in human things. But it is an important part of our health.

Dust mites, bacteria, pollen, ash, sand and many other unhealthy particles rotate constantly in the air you breathe. Fortunately, the mucus helps filter some of these particles, so unhealthy things do not get into your body.

In addition to mucus, nose hair helps filter the air you breathe.


Everyone seems to have a problem with the skin. From hair grown under the skin to bruises, baskets, warts, or wrinkles, there seems to be an endless list of unpleasant things about your skin.

But the reasons why warts, for example, appear on our skin are grounded. Warts are caused by viruses that cause skin rashes.

Molecules are clusters of cells that clump together and from which they can grow hair.Bacteria, skin oil called “sebum” and dead epithelial cells can accumulate together in the pores on the skin and cause the collection of white-pus cells that form the “white head” of the baskets.

When the skin is struck without being broken, a bruising can occur when the lower layers of the skin are injured and the blood is collected in the area.

There is a long list of negative things that can happen to our skin, but understanding these things can help us keep our skin healthy.

Why do we vomit?

Vomiting is a really unpleasant part of our lives. When the stomach is too full, irritated or if the body tries to get rid of a virus or something more sinister, we vomit. Even if it’s unpleasant, it’s incredibly important.

For example, if someone accidentally swallows a poisonous substance or drinks too much alcohol, vomiting helps eliminate this substance. From food poisoning to viruses, vomiting is a natural reflex that the body triggers to protect itself.

Why do we have flatulence?

As we all defecate, we all draw winds from time to time. When we drink or eat, gases such as air and carbon dioxide enter the body with food.

Some of these are released by the screaming, others by flatulence. In fact, every day we have flatulence – between 15 and 20 per day.

The winds usually have a smell much stronger than the eructations and, from a social point of view, they are considered to be far more crude. The repellent smell is caused by bacterial activity.

As food is digested and passes through the large intestine, the resulting residues are processed by a wide variety of bacteria. These bacteria help to process food and produce other gas – hydrogen sulphide. This smelly gas is released by flatulence.

In addition, our winds may seem rude because of the noise they are making. The sound is the result of the vibration of the skin around the anus when the gas passes through this area.

Why smell bad?

Body odor is part of life, and in modern times we began to use deodorant to smell fresh and clean every day. Okay, but why smell so bad?

Certain diseases can influence the way a person smells. But, in general, body odor is caused by bacteria.

Our sweat does not have an unpleasant odor, whether you believe it or not. But when bacteria consume sweat, they produce some bad smell.

In addition, the food we eat can cause a bad smell and we all know how repulsive it may be “morning breathing.” This is caused by bacteria that produce odorous residues while we are sleeping.

Swallowing mucus

Our nose has appeared several times on the list and that’s because they are responsible for many things. If vision of mucus causes disgust, the image of someone who swallows these secretions may be even more rude.

Maybe we can sneak away the irritants from the nose, or maybe they’re caught by mucus or nose hair. But the irritants that escape are collected by slippery mucus.

Cilia, like microscopic hair-like structures, help push the mucus (clear and slippery) into the nose. Mucus gathers irritants such as dust and debris.

Besides sneezing, blowing nose or cleaning the nose to get rid of residue, people swallow on average tens of milliliters of mucus a day. This does not allow the irritants to reach the lungs.
