Little-Known Secrets of the Ear

Little-Known Secrets of the Ear.

In this world, there are many things that often escape the word gratitude, one of which is gratitude for being given the ability to hear. We can listen to people talking to us, enjoy music when we're lonely, to hear our mother's screams telling us to buy chilies at the stall. From beautiful voices to loud, deafening sounds, all are blessings to be grateful for.

The ear that we use to hear is one of the most sensitive organs in the body. Many things have the potential to damage the ears, such as listening to music too loudly through earphones, cleaning the ears too loudly using a cotton bud, and many more.

However, the ear is also a sophisticated organ. To overcome this sensitivity, the ear has a protection system that is able to produce a waxy substance to protect the ear from harmful foreign objects. In addition, the ear also stores other facts that are rarely known, as summarized from CNN Indonesia below:

1. Ears have self-cleaning system

You may choose a cotton bud to clean the inside of the ear. However, be careful, the use of cotton buds that are not appropriate, such as too hard and deep, can damage the waxy tissue in the ear. In fact, wax is a protective substance for the ears. This substance is produced by the ear to protect itself.

Wax substance is like a shield that protects the ear from foreign objects that are harmful to the ear. Cool again, if the production of excessive wax, the ear is also able to clean itself. The excess wax can come out by itself with the help of cilia or fine hairs in the ear.

2. In-ear 'pop' sound

This sound usually appears when you yawn, and after a while the ear returns to normal. This happens because the eustachian tube of the ear opens to keep the pressure in the middle ear stable, so that the pressure inside and outside the ear becomes the same.

In addition, you may often feel like your ears are closed when traveling from lowlands to highlands. These things are an ear protection system from the dangers of air pressure. Sophisticated yes!

3. Ears help balance the body

Not only serves to help humans hear, the ear also maintains the balance of the body. You might think that humans can stand upright because of their legs.

However, don't get me wrong, ears are also able to help humans stand up straight without falling. In addition, the ears also help maintain the balance of the head. This is because the ear has a labyrinth that plays a very large role in the balance system.

4. Nausea while traveling

Nausea is a common thing to feel when traveling, whether on land, sea, or air. When you are nauseous, the discomfort in your stomach may make you think that something is wrong in your stomach.

In fact, did you know that nausea is a sign that something is wrong with your ears? This occurs due to movement on the way that makes the balance system in the ear disturbed. As a result, the body will feel very uncomfortable nausea.

5. The process of listening never stops

When you sleep, you will be in an unconscious state. However, it turns out that the ears still work even though you are sleeping. You don't hear sounds when you sleep because your brain is resting, but when the alarm goes off, people will wake up immediately. This is a reflex reaction of the brain because the ears never stop working.

6. The main cause of deafness

When you hear a sound that is too loud, your ears will usually ring. This is an indication that the sound entering the ear is too loud. On average, the sound that the human ear can hear is only about 60 decibels.

More than that, it can cause deafness. In fact, if humans hear sounds of more than 86 decibels, the ear can lose hearing function. This condition gives rise to the fact that sound induces the ability to hear.

7. Hair cells in the ear

This is one of the most important 'personnel' of the ear. Hair cells function to help the process of hearing in the ear. Its job is to deliver sound waves to the brain. Then, the brain will analyze and understand the sound. If these cells are damaged, hearing loss to deafness can occur. This disorder cannot be cured because hair cells cannot grow back.

Reflecting on these facts, we should take good care of our ears, because as one of the five senses, ears have contributed a lot in helping us to know the world. The ear is the only true writer and the only true reader.
