Goal: Walk one mile as quickly as possible. Execution: We suggest that you DO NOT attempt this test until you are routinely walking for 15 to 20 minutes several times per week. Do not perform this test on a treadmill, as it will skew your results. Warm up by walking slowly for 3-5 minutes.
Causes of Nasal Valve Collapse. Plastic surgery to the nose, or rhinoplasty, is the most common cause of nasal valve collapse. Also, a nasal valve collapse can occur after trauma to the nose or nose surgery as the result of inflammation, enlarged tissue or even scar tissue.
Anosmia Causes. Nasal congestion from a cold, allergy, sinus infection, or poor air quality is the most common cause of anosmia. Other anosmia causes include: 1  Nasal polyps -- small noncancerous growths in the nose and sinuses that block the nasal passage. 2  Injury to the nose and smell nerves from surgery or head trauma. 3  Exposure to toxic chemicals, such as pesticides or solvents.
