Question

На морозе врачи советуют дышать носом , а не ртом . Почему они дают такой совет?

Answer 1

Проходя через нос, воздух согревается, а если дышать ртом, то воздух поступает в лёгкие через горло, которое от этого начинает болеть! 

Answer 2

Если мы будем дышать через рот, то быстро простудимся(подхватим ангину). А когда дышим через нос холодный воздух проходя через нос нагревается и очищается.

Answer 3

Why Do Doctors Advise Breathing Through the Nose in Cold Weather?

In cold weather, doctors advise breathing through the nose rather than the mouth for several reasons:

1. Air Filtration: - Breathing through the nose helps filter and warm the air before it reaches the lungs, reducing the risk of respiratory issues.

2. Humidification: - The nasal passages humidify the air, preventing the respiratory system from drying out, which can help reduce the risk of infections and irritation.

3. Protection Against Cold-Induced Asthma: - Breathing through the nose can help prevent cold-induced asthma by warming and humidifying the air before it reaches the lungs.

4. Reduced Risk of Hyperventilation: - Nasal breathing can help regulate the intake of air, reducing the risk of hyperventilation, which can occur when breathing rapidly through the mouth in cold weather.

5. Enhanced Oxygen Uptake: - Nasal breathing allows for better oxygen uptake due to the increased resistance of the nasal passages, which can improve overall respiratory efficiency.

In summary, doctors advise breathing through the nose in cold weather to benefit from the air filtration, humidification, and protection it provides, while also reducing the risk of respiratory issues and improving overall respiratory efficiency.
