What if you looked perfectly healthy but struggled with exhaustion, poor sleep, and breathing difficulties that no one could explain?

In this episode of Breathe, Sleep & Smile, Dr. Mark Cruz sits down with veterinarian Dr. Lexi Nichols, who shares her personal journey of discovering how an overlooked airway issue was affecting her sleep, energy, and overall well-being.

Despite being young, active, and physically fit, Lexi experienced years of restless sleep, daytime fatigue, and difficulty breathing through her nose. What she initially attributed to a previous nasal injury turned out to be part of a much bigger picture involving upper airway resistance syndrome (UARS), facial development, and nervous system function.

Together, they explore the surprising similarities between human airway problems and breathing difficulties in flat-faced dog breeds, why straight teeth don't always mean a healthy airway, and how tongue posture, jaw development, and early childhood feeding habits influence long-term health.

Lexi also asks an important question: What can parents do early in life to help protect their children's airway health?

Discover why understanding the root cause of breathing difficulties could change the way we approach sleep, dentistry, and lifelong wellness.
