At a family gathering full of laughter, I overheard an elder ask a seemingly ordinary but curious question: "Have you noticed why some people have wet earwax while others are dry?" The question was curious to be answered.
Earwax, or earwax, is often overlooked or simply used as an object of cleaning. However, the type of earwax – whether wet or dry – is actually closely related to our genetics, health status, and even the environment in which we live. Understanding the science behind earwax not only allows us to take better care of our ears, but also helps us gain insight into signals that our body may not be aware of.
Earwax: Not just dirty, but an umbrella for the ears
Earwax, medically known as earwax, is a common ear discharge in people. Although many people think that it is dirty, earwax actually plays an important role in protecting the ear canal. Earwax is produced by secretory glands in the skin of the ear canal, and its main function is to protect the inside of the ear canal from the invasion of dust, bacteria, and other tiny particles. In addition, it lubricates the ear canal and reduces skin dryness and itching.
There are usually two types of earwax: wet and dry. The difference between these two types is mainly determined by genetic factors. Wet earwax is thicker, yellow or brown in color, and contains more lipids and pigments. Dry earwax, on the other hand, is dry, brittle and usually light-colored. This type of difference is caused by a variation in a specific gene that determines the nature of the wax gland secretion in the ear.
It is important to note that the type and amount of earwax may vary with age, dietary Xi, personal hygiene Xi, and even climate change. For example, changes in physical health can sometimes affect the texture and quantity of earwax. Some ear diseases, such as inflammation of the external auditory canal, may also alter the nature of earwax.
While earwax plays an important role in keeping the ear canal healthy, excessive accumulation or improper handling may lead to ear canal blockage or other problems. Therefore, knowing the basics of earwax and the correct way to clean it up is essential to maintain your ear health.
The main factors that affect the type of earwax
1. Genetic Code: Unraveling the Mystery of Earwax Wetness and Dryness
The first key factor in the type of earwax is genetics. Scientific studies have shown that specific genetic variants determine the humidity of earwax. This variation is mainly found in a certain genetic region, which controls the nature of ear gland secretion. The distribution of this genetic variant varies significantly across populations, which explains why certain ethnic groups or family members have similar earwax types. For example, dry earwax is more common in some Asian and Native American groups, while wet is more common in African and European groups.
2. Health and earwax: more than a story about the ear canal
Earwax is not just the excrement of the ear canal, it may also be a reflection of our health. Certain ear conditions, such as inflammation or infection of the external ear canal, can cause changes in the texture and humidity of the earwax. This change is sometimes a direct response of the body to a pathological state. In addition, systemic health problems, such as metabolic diseases, may also indirectly affect the nature of earwax. Therefore, observing changes in earwax can sometimes be a clue to look for an underlying health problem.
3. Environmental influences: Earwax reveals the secrets of life
The properties of earwax are also influenced by environmental factors. People living in different climates may have different earwax properties. For example, people who live in dry climates may be more inclined to develop dry earwax, while hot and humid environments may cause earwax to be more humid. In addition to climate, an individual's Xi and environmental hygiene may also have an impact on the nature of earwax, such as regular use of headphones or earplugs, which may change the microenvironment of the ear canal, thus affecting the characteristics of earwax.
Earwax is not the enemy: a pro guide to cleaning earwax properly
Earwax, or earwax, is often misunderstood, but it's actually part of our ear's self-protection mechanism. Proper earwax removal is essential to maintaining ear health. Here are some professional and safe ways to clean up earwax:
Avoid using cotton swabs or sharp objects
Many people are Xi using cotton swabs to clean their ears, but this practice can be counterproductive. Cotton swabs can push earwax deeper into the ear canal, causing blockages and even damaging sensitive ear canals and eardrums. Therefore, it is very important to avoid inserting a cotton swab or any sharp object into the ear canal.
Self-cleaning ability of the ear canal
The human ear has the ability to clean itself. Earwax usually moves towards the opening of the ear as the skin inside the ear canal naturally sheds and eventually falls off naturally. Therefore, in most cases, the ears do not require excessive intervention to keep them clean.
Gently cleanse the outer ear
When cleaning the ears, the focus should be on the outer ear part. The outer ears and pinna can be gently washed with warm water while bathing. Using a mild soap can remove dust and excess oil from the pinna, but remember not to let water run into the ear canal.
Dry ears
After bathing or swimming, gently dry the outside of your ears with a soft towel. If you feel water in your ear canal, you can gently tilt your head to let the water out, or gently shake your head to help the water drain out.
Use of ear drops
In some cases, if the earwax is too hardened, ear drops may be needed. There are specialized ear drops available on the market that can be used to soften earwax and make it easier to shed. But before using any ear drops, it is best to consult a doctor to ensure its safety.
Professional medical help
If you feel discomfort in your ears or have clogged earwax, you should seek help from a medical professional. Your doctor can safely remove earwax and evaluate for other ear health problems.
