This episode of High Performance Health is a powerful reminder that the true path to longevity isn’t found in chasing supplement stacks or living to 160—it’s about becoming immune to aging by mastering the fundamentals. Angela sits down with Dr Jenna Macciochi, immunologist, author, and high-performance breathwork coach, to explore how chronic inflammation, lifestyle, mindset, and motherhood all shape our biological age far more than we realize.

Dr Jenna's new book Immune to Age presents a revolutionary framework: understanding the immune system as a dynamic force through the seasons of life—from birth to old age. In this heartfelt, science-rich conversation, Jenna and Angela dive into everything from burnout and HRV to intuition, parenting, alcohol, and the myth of the perfect biohacking protocol. This is the longevity conversation every woman needs to hear.

 

KEY TAKEAWAYS:

• Chronic Inflammation: The Silent Driver of Aging : The immune system's slow burn of inflammation is the root cause behind most chronic diseases and early aging.

• The Parenting Connection: Children phase-lock to their mother’s HRV—your emotional regulation teaches them how to regulate themselves.

• Burnout & Intuition: Ignoring your intuition and pushing through stress leads to burnout. Slowing down and listening is the real path to resilience.

• Longevity Isn’t Just About Data: Healthspan matters more than lifespan. Fancy tests are fun, but it’s the basics—food, movement, sleep, breath—that move the needle.

• Alcohol, Sleep & Energy: Giving up alcohol even temporarily can have a massive ripple effect on mood, energy, and parenting.

• Immune System Through the Life Course: From womb to old age, your immune system evolves—and it’s never too early or too late to care for it.
