Final answer:
When congested, nose breathing becomes difficult due to excess mucus obstructing the nasal passages, leading to reliance on mouth breathing. Establishing a habit of nose breathing from an early age is crucial for respiratory health.
Explanation:
When we are congested, we cannot breathe through the nose efficiently due to the increased production of mucus, which obstructs the nasal passages. This forces us to rely on mouth breathing to get air into our lungs.
Nose breathing is essential as it helps warm and moisten the air for easier passage into the lungs, while mouth breathing can lead to snoring and other issues.
Establishing the habit of nose breathing early in life is important for overall respiratory health.
