The Energetics of Cancer: Deuterium, Water, Light, & Mitochondria | Dr Petra Davelaar

Sparked 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
