What is the purpose of nasal hair?

Hair

Nose really has a purpose and it is not to keep the manufacturer of trimmer in business. Hair in the nose is one of the first defense lines of the body against harmful environmental pathogens such as bacteria, sponge and spores. When you breathe unfiltered air through the nose, it also inhales any solid particles in this air. The hair contained in each nostril helps to capture larger particles in the sticky mucus layer. That is why hygienists discourage people from complete removal of nasal hair during care. When air passes through the nasal passages, mucus and hair provide heat and moisture. Moisture is an important factor for the rest of the respiratory system such as larynx and lungs. Hair in the form of small cilia also attracts solid particles towards the interface between the nose and the neck. The harmful debris is generally directed to the back of the neck and esophagus to swallow, while the filtered air continues towards the larynx and lungs.

While excessive nose hair can be considered unsightly, it should never be completely removed. Those who decide to remove almost all hair in the nose can find themselves very susceptible to allergic attacks, sinusitis and respiratory infections. Elder people may also want to minimize hair crop, as it often takes longer for the trimming hairs to return. The hair of the nose serves the same purpose filtering as the ear hair that can be overgrown over time.

Hair in the nose can be safely cropped with specialized rotary cutters or mechanical trimming, but to prevent infections or irritation from overgrown hairs should be used great care. Excessive hair can be cropped until it falls under the noseh line, but any aggressive trimming inside the nasal cavities should prevent it. Dryness in the nasal passages can be temporarily released using nasal sprays, but the natural balance of mucus and functional nasal hair should be maintainedASTO, as possible.
