Protecting Your Nose: The First Respiratory Defense
1The nose is the first respiratory barrier filtering bacteria and dust.
2Mouth breathing lets cold, unfiltered air reach lungs, causing illness.
3Maintain indoor humidity and keep nasal mucosa hydrated for health.
📖 Easy Explanation
🔍 Background
In cold, dry weather, many suffer from colds or rhinitis. This news highlights the nose's vital role as the body's first air entry point.
📌 Key Points
The nose acts as a 'natural filter,' warming air and trapping dust. Breathing through the mouth bypasses this, straining lungs and increasing infection risks.
💡 Why It Matters
Drink water often and keep indoor humidity at 50% to prevent dryness. Rinsing the nose with saline after going out is also a great way to stay healthy.
