What if cancer isn’t just genetic or metabolic—but energetic?In this episode of Cultivating Change, host Alex Corey sits down with Dr. Petra Davelaar, cancer researcher of an energetics-based approach to health, to explore one of the most misunderstood isotopes in biology: deuterium.Water cheat sheet: https://www.alexandercorey.comSparked by a deeply personal journey after her mother’s cancer diagnosis, Dr. Petra breaks down how deuterium, water, light, mitochondria, and circadian biology intersect to influence cellular communication, metabolic water production, and cancer risk.We dive into:-Why physics—not biochemistry—is a more comprehensive view of biology-Cancer as an energetic and coherence problem-What is deuterium and how does it get into water and food-How deuterium alters energy transfer inside cells-The role of metabolic water, the glycocalyx, and mitochondrial structure-Nano-bubbles and dissolved gases in human biology-Why light exposure, food seasonality, and coherence matter more than most people realize-How modern stressors like blue light, nnEMF, and glyphosate disrupt cellular energetics-Glyphosate’s impact on deuterium handling-Cellular voltage, communication, and disease-Practical, grounded steps you can take today to support mitochondrial and metabolic health👇 Resources & Links• Dr. Petra Davelaar: https://drpetra.com• Book a free 15-minute Water Discovery Call with Alex (link below)https://www.alexandercorey.com/contactFollow:IG | https://instagram.com/alexanderscoreyWeb: | https://www.alexandercorey.com👍 If you found this valuable, please like, subscribe, and share to help spread these conversations.--------------------------------Timestamps-----------------------------------00:00 – Introduction & Why This Conversation Matters03:30 – Dr. Petra’s Personal Journey Into Cancer Research00:07:45 – What Is Deuterium?
