Champion powerlifter David Herrera explores the science of light therapy, deuterium depleted water, magnetism, and how it impacts energy production for human performance.David Herrera joins the show to explain his transition into studying the biological effects of light. After discovering the work of Jack Kruse through a podcast, Herrera began investigating how specific frequencies impact recovery and systemic health.This conversation breaks down the practical applications of circadian biology for athletes and anyone looking to optimize their physiological baseline. We examine the mechanism of action behind light therapy, cold exposure, magnetism, and light environment serves as a foundational lever for human health.
