为什么感冒了鼻子会堵？

感冒是一种常见的疾病，其主要症状之一就是鼻子堵塞。这是因为感冒引起的病毒感染导致鼻腔和鼻窦发炎，引起鼻黏膜肿胀和分泌物增多。这种病理变化导致鼻子堵塞，并影响呼吸。

The common cold is a prevalent illness, with one of its main symptoms being a blocked nose. This is due to viral infection caused by the cold, which leads to inflammation of the nasal cavity and sinuses, resulting in swelling of the nasal mucosa and increased secretion. These pathological changes cause nasal congestion and affect breathing.

鼻子的正常功能是过滤空气和保持湿润。它通过粘液和纤毛来清除空气中的细菌、病毒和其他颗粒物。当感冒病毒入侵鼻腔时，免疫系统会释放化学物质来对抗病毒。这些化学物质导致血管扩张和鼻腔黏膜肿胀，从而限制了空气的流动，使鼻子堵塞。

The nose serves the purpose of filtering air and keeping it moistened. It clears bacteria, viruses, and other particles from the air through mucus and cilia. When the cold virus invades the nasal cavity, the immune system releases chemicals to combat the virus. These chemicals cause blood vessels to dilate and nasal mucosa to swell, thereby restricting the flow of air and causing nasal congestion.

此外，感冒还会导致鼻腔分泌物的增加。当感冒病毒感染鼻腔时，免疫系统会释放更多的黏液来帮助清除病毒。这些分泌物堆积在鼻腔中，进一步阻塞了鼻子。

Furthermore, the common cold also leads to an increase in nasal secretions. When the cold virus infects the nasal cavity, the immune system releases more mucus to aid in clearing the virus. These secretions accumulate in the nasal cavity, further obstructing the nose.

人们在感冒期间通常会经历流鼻涕和打喷嚏。这些是身体试图将病毒从鼻子中清除出来的方式。流鼻涕是鼻腔产生的过多分泌物通过鼻孔排出的结果。打喷嚏则是将病毒或其他刺激性物质从鼻腔迅速排出的自我保护反应。

People often experience a runny nose and sneezing during a cold. These are the body's attempts to clear the virus from the nose. A runny nose is the result of excessive nasal secretions being expelled through the nostrils. Sneezing, on the other hand, is a self-protective reflex to quickly expel the virus or other irritants from the nasal cavity.

对于鼻子堵塞的症状，人们可以尝试一些缓解方法。例如，用温盐水冲洗鼻腔可以帮助清除分泌物和减轻堵塞感。使用蒸汽或加湿器可以增加空气湿度，舒缓鼻腔并减少不适感。此外，保持充足的休息和饮水也有助于加快康复。

In dealing with the symptoms of nasal congestion, people can try some remedies. For example, rinsing the nasal cavity with warm saline solution can help remove secretions and alleviate the feeling of congestion. Using steam or a humidifier can increase air humidity, soothing the nasal cavity and reducing discomfort. Additionally, getting plenty of rest and staying hydrated also aid in faster recovery.

总而言之，感冒导致鼻子堵塞是因为病毒感染引起了鼻腔和鼻窦的炎症，导致鼻黏膜肿胀和分泌物增多。这些病理变化限制了空气流动，使鼻子堵塞。通过采取适当的措施，可以缓解鼻塞的不适，并促进康复。

In conclusion, nasal congestion during a cold occurs due to viral infection causing inflammation of the nasal cavity and sinuses, resulting in swelling of the nasal mucosa and increased secretion. These pathological changes restrict airflow and cause nasal congestion. By taking appropriate measures, the discomfort of nasal congestion can be alleviated, promoting a faster recovery.
