Short / long answer type questions.
Breathing through nose is healthier than breathing by mouth. Why?

Answer 1

Breathing through nose is better than breathing through the mouth.

• The hairs inside nostrils filter any microbe in the air and it only lets the clean air pass through. The air gets warm and humidified as it passes into our bodies, making it less shocking to our systems. Each nostril takes part in filtering, warming, moisturizing, dehumidifying, and smelling the air.
• Lungs can extract oxygen from the air we breathe primarily on the exhale. Because the nostrils are smaller than the mouth, air exhaled through the nose creates back pressure when one exhales. Work of lung movement would get doubled.
