How to clean nostril healthily?

Sanitation is everyone's good habit, but many people may not have the habit of washing their nostrils. In fact, the cleanliness of nostrils is also very important. ? ? The nose is located at the forefront of the respiratory tract and is divided into three parts: nasal vestibule, nasal cavity and sinus. It has the functions of ventilation, filtration, cleaning, heating, humidification, buzzing, reflection, smell and so on. The nose hair of normal human nasal vestibule skin can filter the inhaled particles in the airflow, making it difficult for foreign bodies to enter and be easily discharged. Particles such as adsorbed dust and lampblack often pile up here into a thick mass, commonly known as booger. Some people don't care, while others pick their noses with their hands when they feel uncomfortable. Some people have long nails because of the habit of picking their noses (or ears). In fact, these are all bad habits. Because the nasal vestibule is not clean, it will affect the function of the nose to varying degrees. Digging the nose is easy to cause skin damage or inflammation here, leading to nasal vestibulitis or nasal furuncle. ? ? So, how can we keep the nasal vestibule clean? It's simple: as long as we wash our faces at the same time to form a habit.
