Ha.....hh.......cheese! If you just sneezed, it's probably because something inside your nose is tickling you or something is bothering you. Sneezing, medically called ``Sternutation,'' is a wonderful way your body uses to get rid of that annoying stuff inside your nose. It's like a little ``security system'' in our bodies.
Why do we sneeze?
Now, let's see, why do we sneeze? Simply put, it happens when the mucous membranes inside our nose become irritated. There can be many reasons for these irritations:
- Dust particles
- Pollen
- Animal dander
- Smoke (like cigarette smoke, car exhaust)
- Viruses that cause illnesses like colds and flu (common cold viruses)
- The strong smell of some perfumes or chemicals
- Inhaling spicy things like pepper and chili powder
- Sudden temperature changes (for example, going from a very hot place to an AC room)
- Some people sneeze when suddenly exposed to bright sunlight . It's called the ``Photic Sneeze Reflex.'' That's pretty amazing, isn't it? We'll talk about that later.
What really happens when you sneeze?
Imagine a small particle of dust entering your nose. At that moment, the 'sensors' inside your nose detect this. They send a message to a special part of your brain that says, 'Here comes a stranger, we need to get him out quickly!' This is what we call the 'sneeze center'.
A special part of the brain called the "Sneeze Center"
This `(Sneeze Center)` is located in the `(brainstem)` part of our brain. To be precise, in the `(Medulla Oblongata)` area. This center is very smart. It's like the `CPU` of a computer. As soon as the message comes in, it gives `orders` to everyone else, saying, `Okay, let's get started now! Everyone get ready!'
What muscles help with this?
A sneeze is not just a simple blow of air through the nose. It is a very complex process. It is like a large orchestra playing together. It requires many muscles in our body to work together, at the same time, and in a very orderly manner.
- Abdominal muscles: These are what give a big push and force to the sneeze.
- Chest muscles: This also helps.
- Diaphragm: This is the largest, flat muscle under our lungs. It is this muscle that helps us breathe normally. Before we sneeze, we take a deep breath, and it is this muscle that helps fill our lungs with air.
- Muscles controlling vocal cords: These are also involved in the "ah-cheese" sound of sneezing.
- Muscles in the back of your throat: These are also essential to this process.
Imagine how all these muscles work together and coordinate within seconds, based on the signal coming from the ``Sneeze Center''! Isn't it amazing how our bodies work?
The secret of closing your eyes
Oh, and one more thing! Have you ever seen someone sneeze with their eyes open? No, it doesn't. When we sneeze, our eyes always close . That's an automatic message from the Sneeze Center, which means it happens automatically. Some people say that it's because they're afraid their eyes will pop out, but that's not a scientific fact. The real reason is that the eyes are closed in this way to protect the eyes from the high pressure of the sneeze. It's also thought to help prevent germs and dust from entering the eyes.
How fast is a sneeze?
Now look at the power of this. When you sneeze, the tiny particles that come out of your nose - that's saliva, that's mucus - can travel up to 100 miles per hour! That 's faster than a car on our highways! Can you imagine that speed? That's why it's so important to use a tissue or sneeze into your elbow when you sneeze. Otherwise, the germs can spread far and wide, and you can infect others.
New research on sneezing
Scientists around the world are studying how powerful sneezing is and how it spreads diseases. Lydia Bourouiba, a researcher at the Massachusetts Institute of Technology (MIT), a famous university in the United States, and her team are conducting a special study on this.
"They use high-speed imaging to videotape the cloud of droplets that come out when someone sneezes. Then, the Bourouiba Research Group uses math to analyze what happens to these droplets, how far they travel, and how long they stay in the air. The hope is that this research will help us better understand how diseases, especially respiratory illnesses like the common cold and influenza, spread so quickly."
Research like this is very important. Because if we understand exactly how a disease spreads, it is easier to find ways to prevent it. Especially during this coronavirus pandemic, knowing things like this is very valuable.
Minor problems that come with sneezing and things to know
When we talk about sneezing, we think of other little things, right? Let's see what they are.
Is it good to hold a sneeze?
Sometimes when we are in an important place, like a meeting, or a temple, we feel like sneezing. Then we try to stop it by pinching our nose and mouth. But it is not really a good idea to forcefully stop a sneeze. Because, as I said before, a sneeze is something that comes out under high pressure. If we try to stop it, that pressure can push inward, damaging the eardrum, damaging the small blood vessels in the neck, sometimes causing problems with the diaphragm, and very rarely, a blood vessel in the brain can burst (brain aneurysm rupture). Therefore, if a sneeze is coming, the best thing to do is to let it go. But, politely, and in a way that does not bother others.
How do you sneeze properly?
When you sneeze, it's important to reduce the spread of germs to others. Here's how:
- Always use a handkerchief or tissue. Throw the tissue in a closed trash can after sneezing. Wash the handkerchief well with soap and let it dry in the sun.
- If you don't have a tissue, sneeze into your inner elbow. This is much better than sneezing into your hand. Because we open doors, touch other people, and eat with our hands. If we sneeze into our hands, those germs go everywhere.
- After sneezing , be sure to wash your hands with soap for at least 20 seconds or use an alcohol-based hand sanitizer.
Why do I sneeze several times in a row?
Sometimes one sneeze doesn't completely clear out the stuff in your nose. Then, our body says, "Okay, let's try another one!" and we sneeze again, maybe a few more times. It's like giving your nose a thorough clean. Three or four is normal. If it continues longer than that, it could be an allergy. In that case, it's a good idea to see a doctor.
Photic Sneeze Reflex
I've said before that some people sneeze when they are suddenly exposed to bright sunlight or when they look at a bright light. It is said that between 18% and 35% of the population has this condition. It is called `(Photic Sneeze Reflex)` or `ACHOO (Autosomal Dominant Compelling Helio-Ophthalmic Outburst) syndrome`. It is thought to be a genetic `(genetic)` thing. That is, it is something that is passed down from generation to generation. It is thought to be caused by a small `(cross-wiring)`, that is, a confusion of signals, between the `(trigeminal nerve)` in the brain, and the `(optic nerve)`, the light-sensitive nerve in the eyes. This is not dangerous, but it is good to be careful because if it happens suddenly, like when driving, it can be a little distracting.
So, in short, things to remember
Okay, so we've talked a lot about sneezing today, haven't we? In short, remember this:
- Sneezing is a natural defense mechanism that our body uses to clear our nose.
- It is controlled by the ``Sneeze Center'' in the brain, with a very complex muscle function.
- A sneeze is a very powerful and fast thing . So sneeze properly (into a tissue, elbow) to prevent the spread of germs.
- Don't force a sneeze to stop . It can harm the body.
- Sneezing in sunlight (Photic Sneeze Reflex) is a common, genetic condition that some people have.
- Further research into sneezing will help us understand how diseases spread.
So, the next time you sneeze, remember that it's not just a 'cheese' sound, but a very amazing, complex process happening inside your body. And don't forget to think about others and sneeze safely, okay?
