Description

If you've been a long-time podcast listener, then you're no doubt familiar with Dr. Jay T. Wiles, my jolly sidekick on the regular Ben Greenfield Fitness Q&A podcast episodes. What you may not know about Dr. Wiles is that he is a true expert in all things heart rate variability (HRV) testing, tracking, and interpretation; and in this podcast episode, he takes a deep dive into how to use HRV to optimize your recovery, performance, sleep, stress, and nervous system. Dr. Wiles is a clinical health psychologist with a passion for helping others reach their full potential from an integrative and holistic perspective. With this strong passion for integrative and holistic care, especially in nutrition and psychophysiology, Dr. Wiles completed his doctor of clinical psychology degree at Regent University with a specialized focus and concentration in health psychology. Dr. Wiles then furthered this specialty in health psychology as a pre-doctoral intern at McGuire VA Medical Center in Richmond, VA and post-doctoral fellowship at WJB Dorn VA Medical Center in Columbia, SC. He currently works as a health psychologist for the Department of Veteran Affairs. With specialized training in health behavior coaching, health assessment, nutritional interventions for mental and physical health, motivational interviewing, applied psychophysiology (biofeedback and neurofeedback) and consultation, Dr. Wiles works as a consultant for companies, organizations, practitioners, and individual patients on nutritional psychology, health behavior change, applied psychophysiology, and health promotion/disease prevention via complementary and integrative practices. He is also board certified in biofeedback and heart rate variability biofeedback as well as board-certified in Tai Chi for rehabilitation. Dr. Wiles has worked closely with elite athletes and executives on enhancing peak performance through his online consulting agency, . This consulting agency focuses solely on training and regulating psychophysiology for performance. ​He is passionate about education and consultation with patients and organizations in an effort to increase health outcomes through focusing on prevention and well-being, as opposed to disease and symptom mitigation.
