Episode 84 Part 1 - The hidden power of your lymphatic system with Leah Levitan
What if the secret to healing, energy, and resilience has been sitting quietly beneath the surface of your skin all along? Most of us have barely heard about the lymphatic system yet it could hold the key to everything from chronic swelling to brain fog to emotional wellbeing.In this powerful conversation, Celest sits down with Leah Levitan, licensed massage therapist, lymphatic drainage specialist, and founder of the global community The Lymph Love Club. Together they explore why the lymphatic system is so often ignored in medical training and why it deserves centre stage in how we think about health.Leah shares her journey from traditional massage into the world of fascia, fluid, and flow, and why treating the body as an interconnected ecosystem brings more ease and results than chasing symptoms. You’ll hear about emerging research on fascia and lipedema, how swelling shows up in the body (from post-surgical lymphoedema to everyday puffiness), and why yoga teachers might be supporting lymph far more than they realise.In this episode:We learn:Why the lymphatic system is overlooked yet essential for healingThe difference between oedema, lymphoedema, and “invisible swelling”How fascia, nervous system, and lymph work together as the body’s three amigosSimple ways yoga, breath, and movement stimulate lymph flowDebunking the myth that twists don’t “detox”and why movement mattersIf you’ve ever felt heavy, swollen, or stuck in your body, or if you teach students who do this episode will completely shift how you see fluid, fascia, and flow.About LeahWith her extensive training in Myofascial Release Techniques, scar tissue work, trauma informed somatic therapy, organ manipulation, and The Vodder Method of Manual Lymphatic Drainage, Leah has woven together a unique body of work that's designed to support individuals with chronic illnesses. Our body is an ecosystem, and she uses a global approach.Leah created Lymph Love Club as a way to walk people home to their lymphatic systems world wide, and she is s certified lymphedema therapist, Lymph Literacy Advocate, and expert guide into the depths of the lymphatic system's terrain.Follow Leah on Instagram here.About Alba Yoga AcademyLearn more with Alba Yoga AcademyLearn more about our Yoga Teacher Training here.Watch our extensive library of YouTube videos.Follow Hannah on Instagram.Follow Celest on Instagram
