Municipal Health Commission introduced that after Mid-Autumn Festival , the temperature difference between morning and evening becomes larger, and the temperature alternation of cold and heat is likely to cause nose problems. Caring for your nose and preventing diseases is related to everyone's healthy quality of life. Since the role of the nose is so important, how should we protect it in our daily lives? The “three don’ts” of love for nose and nose protection, and more importantly, during the epidemic prevention period, we must pay attention to protection. See ↓

The nose builds three lines of defense for the respiratory tract, so that the air entering the lungs is purified: the nose hair has the effect of blocking the invasion of foreign objects, which is the first line of defense; the curved nasal mucosa covers it, which forms a certain buffer for air inhalation, which is the first line of defense. Two lines of defense; the mucus blanket on the surface of the nasal mucosa has the effect of adhering to dust, which is removed by the unidirectional swing of the cilia, which is the third line of defense.

Love nose and nose protection "three don'ts"

*1

Don't use nasal drops at will

Some people feel nasal congestion and will buy nasal drops at will online or buy nasal drops by themselves. However, some nasal drops contain vasoconstrictors, such as nasal drops, Furosa nasal drops, etc., may have short ventilation after dropping, but the commonly used drugs will cause irreversible lodging of cilia in the nasal cavity, as well as adverse reactions to cardiovascular and central nervous system.

Therefore, if nasal congestion occurs, you should undergo a doctor's examination, identify the causes, and use medication symptomatically. Even if a vasoconstrictor is required for a short period of time, it should not exceed one week.

*2

Don’t pick your nose anyway

Picking nose is a bad habit, it is neither elegant nor hygienic.

nails contain a large number of pathogenic bacteria, including fungi. Picking the nose will bring these pathogenic bacteria backwards into the nasal cavity and sinuses. The humid environment is conducive to the growth and spread of mold clumps.

is a "invasive" fungal infection, and it is also life-threatening.

*3

Do not squeeze nasal boils , pull the nose hair

is located in the upper lip area between the middle of the head and face and the nasolabial groove , commonly known as the "dangerous triangle area".

The vascular network in this area is rich, and the facial veins have no valves, and the blood flows forward and reversely in both directions. Once infected, it will soon spread through the small vein and flow into the inner canthus vein, and then flow backwards through the upper and lower veins of the eye to cavernous sinus , causing serious intracranial complications and systemic sepsis, causing life-threatening.

Therefore, when there is "acne" in this dangerous area, you must not squeeze it. Nose hair should not be pulled or pulled. If the nose hair is too long, it can be cut short. Pulling and pulling will cause folliculitis , with serious consequences.

During the epidemic prevention period, we must pay more attention to protection

*1

Wearing a mask

During the epidemic prevention period, wearing a mask is the "standard configuration" of our lives, which can prevent the respiratory tract from the new coronavirus.

Although the nasal cavity has a cleaning function (nose hair, mucus blanket, cilia, etc.) to prevent the invasion of dust and bacteria, the virus is too small to be invisible and intangible. It can be spread through saliva droplets, coughing, or even breathing, and depends on the function of the nasal cavity itself. Can't resist virus invasion.

*2

Clean the nasal cavity

Normal saline cleaning the nasal cavity can keep the nasal cavity clean.

But it should be noted that our nasal cavity has a certain internal environment of immune function. It is futile and even harmful to wash your nose with clean water or incorrect methods at will.

Warm reminder

Pay attention to taking care of our noses and check any discomfort in time. During the alternation of seasons and the temperature difference between morning and evening becomes larger, people with allergic rhinitis and should take timely protective measures!
