Why Does One Nostril Feel More Open?
The nasal cycle can change which side feels more open as vascular filling alters the lining. Both passages can carry air, and persistent one-sided blockage can have other causes.

What the illustration shows
Navy-and-gold poster titled “Why Does One Nostril Feel More Open?” Two simplified paired nasal passages, Moment A and Moment B, each have a straight ivory central septum and one representative bony turbinate projecting from each outer wall. Peach lining is thicker on the left in A and on the right in B. Cyan arrows on both sides compare airflow, wider in the more-open passage. Text clarifies that the arrows do not trace three-dimensional airflow. Below, tissue cutaways compare thinner lining with smaller red vascular spaces and thicker lining with larger spaces above ivory bone. Key points say bone stays in place and vascular spaces lie within the lining. A note says timing varies and persistent one-sided blockage can have other causes. Gold AllHumanBody.com and the full slogan finish the poster.
How to interpret this poster
- One representative turbinate per side; timing and airflow vary. Arrows are not a three-dimensional flow map or measured percentages.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
