The causes of frequent sneezing include environmental factors, disease factors such as colds, allergic rhinitis and other factors.
1. Environmental factors: When the human body inhales dust, fine dust, irritating gases, smoke, animal dander or feathers, the foreign matter is expelled from the body through sneezing. Sudden changes in temperature can also cause sneezing.
2. Disease factors: for example, when you have a cold, the nasal mucosa becomes more reactive and sneezing occurs; in allergic rhinitis, the sensory nerve sensitivity of the patient’s nasal mucosa is increased, leading to frequent sneezing; people suffering from vasodilatory rhinitis will often sneeze, and so on.
3. Other factors: For example, a few people will sneeze when looking directly at the harsh sunlight, which is called “light sneeze reflex”.
If you have any uncomfortable symptoms, you need to go to the hospital as soon as possible, and the doctor will make individualized treatment plan according to your specific condition, so as not to delay your condition.
