Our nasal cavity is in direct contact with the outside world, and there are a lot of cells and secretions in the nasal cavity, which can prevent harmful substances such as bacteria and dust from entering the respiratory tract and help us feel the taste and smell. But sometimes we also feel dry nasal cavity, which leads to discomfort and affects our health. So what is the cause of dry nose?
1, weather reason
Weather is one of the main causes of nasal dryness. In the dry season, the humidity in the air is low, and the moisture in the nasal cavity is easy to evaporate, resulting in nasal dryness. In addition, the cold weather will also lead to vasoconstriction of nasal mucosa, decreased secretion and aggravated nasal dryness.
2. Drug causes
Some drugs may also cause dry nose. Such as antihistamines, antipyretics, diuretics and antidepressants. These drugs can inhibit body secretions, including nasal secretions, leading to dryness. In addition, some overused nasal sprays may also destroy the self-repair mechanism of nasal cavity, leading to nasal dryness.
3. Health reasons
Dry nasal cavity may also be a symptom of some health problems. Such as nasal infection, nasopharyngeal carcinoma and allergic rhinitis. , it will lead to the decrease of nasal secretions or quality variation, resulting in nasal dryness. In addition, some chronic diseases, such as Sjogren's syndrome and autoimmune diseases, may also lead to decreased systemic secretion, which in turn affects nasal secretion.
4. Causes of daily life
Our daily habits may also lead to dry nose. For example, smoking, talking loudly, looking down at mobile phones and using air conditioners for a long time will all affect the secretion and quality of nasal secretions, leading to dryness. In addition, bad eating habits and lack of drinking water will also affect the moistening of nasal cavity.
In short, dry nose is a common problem, but it may also be a manifestation of some serious health problems. Therefore, we should pay attention to protecting the nasal cavity, maintaining indoor humidity, quitting smoking and limiting alcohol, eating reasonably and drinking more water in our daily life. To keep the nasal cavity healthy.
