Anatomy Video Explains Why Nose Picking Can Trigger Dangerous Bleeds
A viral video from the YouTube channel Institute of Human Anatomy, uploaded on October 4, 2026, examines the risks of nose picking. Host Jonathan uses a human nasal cavity to demonstrate that while removing dried mucus can aid breathing, aggressive scraping with a fingernail can rupture vessels in Kiesselbach’s area, leading to anterior nosebleeds. The video distinguishes these common, manageable bleeds from rare posterior bleeds, which are harder to control and may require medical intervention. It also provides first-aid advice, including leaning forward and applying continuous pressure for 10 to 15 minutes, while noting that uncontrolled hypertension and blood-thinning medications can complicate bleeding.
