Summer is hot and hot is difficult. Many people will cool down by air conditioning, cold drinks, cold water baths, etc., while the outside temperature is high, so that a cold and a hot, accidentally easy to catch a cold, causing nasal congestion, runny nose and so on. Can you know? The snot is also very particular. If the technique is wrong, not only the nose is vulnerable, but also the ears and eyes may suffer.
Many people like to wrap their nostrils with paper towels, and then use their two nostrils to pull out their noses. It is not known that this method not only removes the nasal secretions, but also may not be a small health hazard. Because the nasal cavity and the sinus are connected, at the same time, the nose can easily cause the nose to flow backward, allowing bacteria and viruses to retrograde infection, increasing the chance of suffering from acute sinusitis.
On the other hand, when the snot on both sides is rubbed at the same time, the pressure in the nasal cavity rises sharply, and the secretion with bacteria or virus will flow backward into the nasopharynx of the back of the nasal cavity, if there is secretion of bacteria or virus through the nasopharynx. Entry into the middle ear cavity may cause inflammation in the middle ear cavity, which may lead to acute otitis media or chronic otitis media. The symptoms are: ear nausea, occlusion in the ear. Especially in acute otitis media with otitis, the symptoms of ear suffocation are more obvious; hearing loss is manifested as head position changes such as forward leaning or biased to the affected side, hearing can be temporarily improved; tinnitus, intermittent tinnitus with “click” sound And when the head moves or sneezes and blows your nose, there may be a sound of gas over the ear.
In addition, the use of force to blow the nose may also cause “eyelid emphysema”, which often occurs after trauma or nasal surgery. Under normal circumstances, the soft tissue in the nasal cavity will enclose the gas. If the inner wall of the eyelid is traumatized or has just undergone surgery such as nasal endoscope, the local soft tissue may have certain defects. At this time, the force will blow the nose and the gas will follow. The gap between the soft tissue defects in the nasal lacrimal sac enters the subcutaneous tissue around the eyeball, causing swelling of the eyes and pain.
So what is the correct nose blowing posture?
The answer is “one by one.” First, press and hold one nostril, and then forcefully press the other one, then change the other side to ensure the balance of pressure on both sides of the nasal cavity to prevent retrograde infections such as bacteria and viruses. At the same time, the strength of blowing your nose must not be too large. If the symptoms of salivation caused by a cold are serious, it is recommended to use a nasal irrigator and wash the nasal cavity repeatedly with mild water to help relieve the condition.
It is also worth noting that some people do not like to blow their noses, but habitually suck back the snot, even from the mouth of the nose. However, the snot contains a large amount of mucus protein secreted by the nasal cavity and the pharynx, which encloses a large amount of harmful substances such as bacteria, viruses and dust and promotes the body to discharge these harmful substances. The practice of sucking back is easy to re-enter harmful substances into the body, and it is easy to inhale the trachea and cause suffocation, so it is extremely undesirable.
