Biologist explains why crying causes a runny nose

By PulseAugur Editorial · [1 sources] ·

Crying causes a runny nose due to the eye's natural drainage system, which directs tears into the nasal cavity. When emotional tears increase in volume, this system can become overwhelmed, leading to excess fluid mixing with nasal mucus. Additionally, the autonomic nervous system can cause nasal lining swelling and increased mucus production during intense emotional states, further contributing to congestion and a "stuffy" feeling. Individual anatomical variations in tear ducts can also influence how quickly this backup occurs, explaining why some people experience a more pronounced runny nose when crying. AI
