“We survive in danger, but we thrive in safety.” —Jen Nolan

The nervous system shapes how the body responds to stress, healing, and everyday life, often without us realizing it.

In this episode of the Real Health Podcast, Dr. Kirsten West is joined by Jen Nolan, owner of Remission Nutrition and nutrition advisor at Riordan Clinic, to explore how the nervous system influences the healing process, especially for those navigating cancer and life after treatment.

Jen shares how patterns of chronic stress, fear, and “scanxiety” can keep the body in a constant state of fight or flight. Over time, this can influence inflammation, immune function, sleep, and the body’s ability to adapt.

Dr. West walks through the physiology behind these responses, including the balance between the sympathetic and parasympathetic nervous systems. The conversation also introduces polyvagal theory, offering a clearer picture of how the body moves between states of stress, safety, and shutdown.

You’ll hear how heart rate variability can reflect the body’s resilience and why it can be helpful to notice patterns over time. They also discuss the vagus nerve and its role in communication between the brain and body, influencing digestion, mood, and overall regulation.

The episode closes with practical ways to support the nervous system in daily life. Breathwork, movement, time in nature, and connection with others can all help signal safety and support the body’s ability to regulate.

Throughout the conversation, one idea keeps coming up. Healing involves more than addressing physical symptoms. It also includes creating a sense of safety within the body.
