The Health Upgrade Podcast

In this episode of the Health Upgrade Podcast, Dr. Cindy Howard shares what it's like to experience healthcare from both sides, as a doctor and as a patient. She opens up about her journey of recognizing the signs of Hodgkin's lymphoma in herself and navigating treatment while drawing on her years of experience in functional medicine.
Together, we discuss the emotions that come with receiving a life-changing diagnosis, the importance of self-care, and why personalized healthcare can make a real difference. We also explore gut health, environmental toxins, genetic testing, and how AI is changing the way patients can advocate for their own health.
Dr. Howard explains why asking questions, setting boundaries, and working with healthcare providers who listen and collaborate are essential parts of achieving better health outcomes.
If you or someone you love is lost in the healthcare maze or facing a critical diagnosis, this episode is for you. Listen in, share the episode with a friend, and empower yourself to be an informed, proactive participant in your own health journey!

In this episode of the Health Upgrade Podcast, I talk with Waldi Hoon, the founder of yōjō, about her journey into the world of vagus nerve health. She shares how her background in content creation, along with her family's experience with chronic pain, inspired her to help others improve their health using science-based solutions.
We also discuss how modern life, from constant stress to information overload and unhealthy habits, affects our nervous system. Waldi explains why building resilience, creating simple daily routines, and finding the right self-care practices can make a big difference. We also explore how YoJo's technology and community help people make these healthy habits part of everyday life.
If you're looking for practical ways to reduce stress, improve your wellbeing, and learn more about nervous system health, this episode is for you. If you find it helpful, share it with three friends who could benefit too.

In this episode, I explore the connection between your light environment, the vagus nerve, and heart rate variability (HRV). Drawing on a 2025 systematic review of 25 studies, I explain how both the timing and quality of light exposure can influence nervous system function and overall recovery.
I discuss how morning exposure to bright, blue-enriched light helps regulate your circadian rhythm and support healthy biological rhythms, even if it may cause a temporary reduction in HRV. In contrast, warmer, dimmer light in the evening can help promote relaxation and prepare the body for restful sleep.
I also share practical strategies for optimizing your daily light exposure, particularly for individuals who experience anxiety, stress, or heightened sensitivity to environmental factors.
As a simple challenge, I invite you to pay closer attention to your light habits for one week. Aim to get natural light in the morning and use warmer, lower-intensity lighting in the evening. Observe how your HRV responds over time, rather than focusing on moment-to-moment changes. 
If you find this episode valuable, share it with someone who may benefit from it. Small changes in daily habits can have a meaningful impact on long-term health and well-being.

Welcome to another episode of the Health Upgrade Podcast!
Today I am joined by Dr. David Rabin to dive deep into the science of stress, healing, and the power of the vagus nerve. Dr. Rabin unpacks decades of research, explaining how chronic stress impacts our cells, the crucial role of safety in the healing process, and how modern medicine often misses the importance of looking at the whole person rather than isolated symptoms. Together, we reveal how ancient practices align with the latest neuroscience, showing that mindful breathing, touch, and familiar, calming experiences directly influence our health.
The conversation also explores cutting-edge topics like MDMA-assisted therapy, epigenetics, and the power to reverse trauma at both psychological and genetic levels. Dr. Rabin discusses how trauma can be inherited, and more importantly, how healing is absolutely possible, with evidence-backed tools and practices ranging from technology like Apollo Neuro to traditional approaches such as yoga, meditation, and breathwork.
If you’re looking to upgrade your health and feel empowered in your healing journey, this episode is for you. Share it with friends who could benefit, and discover practical steps you can take today to reconnect your mind and body for a healthier, happier life!

In this episode of the Health Upgrade podcast, returning guest Don Moxley joins us to talk about heart rate variability (HRV) and why it matters for your health, recovery, performance, and healthy aging.
Drawing on his experience working with elite athletes, Don explains how HRV can help you understand how well your body is adapting to stress and recovering from daily challenges. He also discusses the factors that influence HRV, including sleep, exercise, nutrition, past trauma, and your environment.
The conversation highlights the connection between HRV and aging, showing how simple habits like regular movement, healthy food, quality sleep, and strong social relationships can help improve HRV and support long-term health. Don also introduces HRV Plus, a supplement designed to help manage inflammation and improve resilience to everyday stress.
If you want to learn how to better understand your body's signals and discover practical ways to improve your health and age well, this episode is for you.
