Noses work by providing asymmetrical airflow, allowing for rest cycles for their air-conditioning function, and enabling periodic obstruction of one nasal passage to potentially aid in overcoming viral infections.
Here's a more detailed explanation:
-
Asymmetrical Airflow: The two nasal passages don't operate with equal airflow all the time. There's a natural nasal cycle where one side experiences increased congestion and reduced airflow while the other side has more open airflow. This cycle alternates, switching sides roughly every few hours.
-
Rest Cycles for Air Conditioning: The nasal passages are responsible for warming, humidifying, and filtering the air we breathe. The alternating airflow allows each side to have periods of rest and recovery, preventing them from becoming overworked and inefficient.
-
Potential Viral Infection Defense: Temporary blockage of one nasal passage, as occurs during the nasal cycle, can slightly increase the temperature within that passage. This elevated temperature may create an environment less favorable for viral replication, potentially aiding the body in fighting off viral infections.
In short, noses, with their paired passages and cyclical airflow, perform crucial functions in air conditioning and potentially in combating viral infections.
