【Laiwo Medical: Knowledge Sharing】Teacher's Day: Stick to the blackboard, don't sacrifice your health! This nose protection strategy is very important
Publish Date： 2025/9/10
Chalk dust fluttered in the sunlight, like stars in the sky, turning into the brightest mark of the teacher's youth.
Classmates, as soon as the teacher finished speaking on the podium, he suddenly turned around and covered his nose, sneezing several times in a row, and the chalk dust gently lifted up with his movements. Rubbing the reddened nose tip, he continued teaching with a smile. Perhaps every student has seen this scene in class, but few know that behind the teacher's frequent rubbing and sneezing of the nose is the "occupational injury" that the nose endures day after day. ?
The teacher's nose undergoes these 'invisible tests' every day:
The Long term Bombardment of Chalk Ash
Even using 'dust-free chalk' can generate fine dust after a class. The teacher stood in front of the podium, closest to the blackboard, and the dust directly drifted towards the nasal cavity, stimulating the nasal mucosa. So, dryness and itching became the norm, and in severe cases, it can also cause allergic rhinitis. As soon as I entered the classroom in the morning, the teacher began to sneeze and have a runny nose.
The additional burden associated with using one's voice
The teacher has to teach 4-6 classes a day and unconsciously accelerates breathing when speaking. Many teachers are accustomed to breathing through their mouths, as dry air rushes directly into their throats and nasal cavities, quickly removing moisture from their noses. Over time, the nasal mucosa can become fragile and even experience damage and bleeding.
Teachers' exclusive nose protection guide
1. 3 minutes before class: Put on protective clothing for the nose
Use nasal spray 3 minutes before the bell rings. It can form a protective shield on the nasal mucosa, reducing the direct adhesion of chalk dust during subsequent blackboard writing, and reducing the probability of dry and itchy nose from the source. You can easily place it by the lectern during lesson preparation, and develop a habit of nose protection.
2. When writing on the board: change your posture and absorb less dust
When writing on a blackboard, you don't need to stand facing the blackboard. Try writing sideways. Turn your body slightly towards the student, with your shoulders at a 45 degree angle to the blackboard. This will allow the student to see the board clearly and avoid the dust drifting in the right direction. You can also wipe it with a damp cloth (wring it out in advance without dripping water) to further reduce dust diffusion and minimize irritation to the nasal cavity.
3. After class: Don't stay in the classroom too long, take a breath first
Just finished a class, there are still residual chalk dust floating in the classroom. Don't rush to stay in front of the podium to grade homework or answer questions. You can first go to the hallway or open the classroom window, let your hands naturally hang down, close your eyes and slowly take deep breaths 5 times, letting fresh air flow through your nose through your respiratory tract, taking away any remaining dust and giving your nose time to "breathe a sigh of relief".
4. After returning home: give your nose a thorough bath
After a busy day, you can go home and get a "cleaning SPA" for your nose under the guidance of a doctor. Fill a professional nose wash with physiological saline, tilt your head slightly to one side, let the saline flow in from one nostril and out from the other, and slowly rinse for 1-2 minutes. This can flush away the accumulated "dirty things" such as chalk dust, pollen, and dust in the nasal cavity for a day, relieving the dryness and fatigue of the nasal mucosa.
Every moment you stand in front of the podium, there is a passion for spreading knowledge hidden in your voice, but your nose quietly bears the test of dust. And your health is the most solid cornerstone in the classroom, the most reassuring reliance in the eyes of students. On this Teacher's Day, please accept this small nasal care, hoping it can help you brush away any discomfort in your nose. Finally, Laiwo Medical deeply pays tribute to every teacher who silently adheres: Thank you for your selfless dedication, you have worked hard, and happy Teacher's Day!
