We've all been through crying, and when tears wells up, snot often follows. So, why do people have runny noses when they cry?What kind of scientific principles are hidden behind this?
First of all, we need to understand that tears and snot are both natural reactions of our bodies. When our eyes are irritated, such as sadness, pain, etc., tears are secreted to help us flush out foreign bodies and irritants in our eyes. And when we cry, in addition to tears, our nose is also irritated, leading to the secretion of nasal discharge.
Secondly, there is a strong connection between tears and snot. Between our eyes and nose there is a structure called the "nasolacrimal duct".
When tears are secreted excessively, a portion of the tears flow through the nasolacrimal ducts into the nasal cavity and mix with the nasal discharge. That's why when we cry, the snot becomes sticky.
In addition, the emotional state of the person can also affect the secretion of tears and nasal discharge. When we feel negative emotions such as sadness, frustration, etc., the body produces a lot of stress hormones, such as adrenaline, etc. These hormones can irritate the eyes and nose, leading to an increase in the secretion of tears and nasal discharge.
Finally, it is important to note that while a runny nose when crying is a normal physiological response, excessive tearing and runny nose can have adverse effects on our body. Therefore, when facing negative emotions, we should learn to control our emotions and avoid excessive tears and runny nose.
In conclusion, a runny nose when someone cries is a natural reaction of the body and a manifestation of our emotional state. Understanding the science behind this can help us better understand our physical and emotional state, so we can better cope with life's challenges and stresses.
