In her recent appearance on Nutrition Gateway, Dr Mary Bourke joined Sally-Anne Kearns for a compelling discussion on a topic rarely explored in conversations about women's health: the relationship between oral function, breathing patterns, sleep quality and nervous system regulation.

Drawing on more than three decades of clinical experience, Mary explains how everyday functions such as breathing, chewing and swallowing influence far more than oral health. These foundational patterns can affect sleep quality, energy levels, stress resilience, cognitive performance and overall wellbeing.

The conversation is particularly relevant for women navigating perimenopause and menopause. As changes in muscle tone occur with age, airway function and sleep quality can become increasingly compromised, often contributing to symptoms such as fatigue, brain fog, anxiety and poor recovery.

“When we look at symptoms such as fatigue, anxiety, brain fog and poor sleep, we don't always think to look at breathing, chewing or oral function,” Mary explains. “Yet these fundamental patterns influence how the nervous system regulates, how we recover during sleep, and ultimately how we function every day.”

Rather than focusing on another health trend or quick fix, Mary highlights the importance of understanding the body's innate design and the role that healthy oral function plays in supporting long-term wellness. From nasal breathing and tongue posture to the impact of chewing on nervous system regulation, the episode offers a fresh perspective on health optimisation.

For women seeking a deeper understanding of the factors influencing their sleep, energy and wellbeing, this conversation provides valuable insights into an often-overlooked area of health.
