The most common saying of sneezing in China is "think twice, scold three times", which means that once you sneeze, someone will think of you, twice you sneeze, someone will scold you, and three times you sneeze, someone will say something. In fact, this statement has been circulating for thousands of years-it can be traced back to the Book of Songs at the earliest, especially this "one thought", which brought the romantic feelings of the ancients to the extreme.
The Book of Songs is a poem describing the love between men and women. There is a sentence in it, which means "I miss you so much that I can't sleep." If you miss me as much as I miss you, then I will sneeze. " The seemingly unsightly "sneeze" here is comparable to spinach in autumn, which sustains the suffering of men and women.
Scientific explanation:
This is a statement without scientific basis. If sneezing persists with a runny nose and stuffy nose, you may have caught a cold. Human nasal mucosa is very sensitive.
Once stimulated physically or chemically, it will react with the extremely fast airflow generated by sneezing, and thoroughly clean the upper respiratory tract. If the nasal cavity continues to be stimulated by smoke, dust, pollen and pungent smell, it will lead to sneezing. Usually, the upper respiratory tract will secrete a lot of clear tears to help eliminate bad stimulation.
