Why do boogers come out when you cry?

Boogers, or nasal mucus, can be expelled when you cry due to the increased production of tears, which can lead to a runny nose. Tears drain through the nasal passages, causing the mucus to become more fluid and potentially mix with it. Additionally, emotional crying can trigger the body's stress response, which may also increase mucus production. This combination can result in a noticeable discharge from the nose while crying.
