There is actually a lot of knowledge about sneezing! Whether you hold it in or sneeze, you have to be careful!

Ah... sneeze!

According to popular belief, the number of times you sneeze has a special meaning.

A sneeze means someone is thinking about you;

Sneezing twice means someone is cursing you behind your back;

Sneeze three times, you may have a cold;

It sounds interesting, but is there any scientific basis for this statement?

"Ozawa comes to explain"

If someone really misses you, the first thing that should react should be your phone rather than your nose.

Let's first explain why people sneeze. Sneezing is a natural physiological phenomenon of the human body. This is because there are many nerve cells distributed on our nasal mucosa, and these nerve cells are very sensitive. When stimulated, such as smelling pungent chili powder, small flies or dust flying into the nose, including the germs that cause colds, the nose will sneeze reflexively to eliminate these external stimuli and play a role in protecting the nasal cavity.

So why do we sometimes sneeze several times in a row?

Of course, it is still related to various external stimuli. If a sneeze does not completely drive away the "invader" in the nasal cavity, the body will naturally sneeze a few more times.

Do you feel refreshed after sneezing? But Xiaoze wants to remind everyone! Don't sneeze too exaggeratedly, or you may hurt your waist!

Alas, Ozawa is not exaggerating. Some time ago, a 24-year-old boy suffered from lumbar disc herniation after sneezing, and was taken directly to the hospital for transforaminal endoscopic lumbar disc surgery.

Why does sneezing cause lower back pain?

Sneezing can cause back pain for several reasons.

1. When you sneeze, your body will be shaken violently, and the stability of your lumbar spine will be severely tested;

2. When many people sneeze, they will subconsciously turn away from the people around them out of politeness. This sudden turning action may cause muscle strain in the neck and waist and back, causing spasmodic pain and discomfort;

3. When you sneeze, the body will instantly inhale a large amount of air, causing increased abdominal pressure, thereby increasing the pressure on the lumbar intervertebral disc and causing damage.

4. Sneezing can put pressure on the sciatic nerve, which runs through the spine and pelvis, so it can cause numbness and pain in the waist and even legs.

5. If you suffer from severe osteoporosis, sneezing may also cause vertebral compression fractures, which are most common among the elderly.

In addition to not sneezing too much, don't hold your sneeze. Sneezing is so comfortable, but it's very uncomfortable to hold it in. Especially if you hold it in because you're afraid of disturbing others, it's really unfair to your nose! It can also cause harm to your body.

Where do all the held-back sneezes go?

Ears: A held-back sneeze may go directly into the ear. The air pressure that should have been expelled from the body is applied to the ear, which may cause the eardrum to rupture and hearing loss. Many people will also feel dizzy.

Lungs: Sneezing is a kind of "exclusion" reflex protection mechanism of the body. If you hold back your sneeze, you will not be able to drive foreign irritants out of your nasal cavity. These foreign substances can easily enter the lungs, harm our lung tissue, and even cause lung perforation.

Eyes: The air pressure cannot be discharged from the body, and the ears cannot hold it, so the eyes will naturally be chosen as the next "vent point". This may cause ugly goldfish eyes!

Blood vessels: If the elasticity of the blood vessels is poor, or if the patient suffers from cardiovascular and cerebrovascular diseases, it will not only cause a surge in blood pressure, but may also cause cerebral blood vessels to rupture! Just thinking about that scene is spectacular!

It seems that there is a lot of knowledge about sneezing!

Whether you sneeze or not, a sneeze will always "tell" you its power in its own way.

In short, you can't hold it in, and you can't use too much force.

Don't worry about an occasional sneeze. A minor cold will heal in a short time. But if the sneezing is frequent and persistent, and is accompanied by other allergic symptoms, remember to see a doctor to find out the cause. Don't ignore it as a minor cold.
