What does sneezing mean?

One scolding, two thinking and three thinking.

Someone scolds you when you sneeze; When you sneeze twice,

Someone misses you; When you sneeze three times, someone is talking about you.

In fact, sneezing is a stress reaction of human self-protection. When a foreign body enters the nasal cavity, the cells in the nasal cavity are stimulated, and the muscles around the lungs contract rapidly, generating a high-speed airflow to expel the foreign body from the nasal cavity. When people catch a cold, the nasal mucosa will also be stimulated and they will sneeze.

It's just that sneezing when people catch a cold is often stimulated by cold air. Sneezing is a way for the body to remove nasal irritants or foreign bodies.
