Shining the Light on Sleep and the Circadian Rhythm with Corey Ghazvini

How is the quality of your sleep? Poor sleep can negatively affect your health, causing weight gain, depression, and other ailments. Corey Ghazvini's life's work is centered on how to optimize sleep and metabolism.

Corey graduated from Florida College of Integrative Medicine with a Bachelor's Degree in Professional Health Studies as well as a Masters Degree in Oriental Medicine. He is nationally board certified in Acupuncture, Chinese Herbology, and Biomedicine. During his internship, Dr. Ghazvini quickly recognized that the majority of his patients' conditions were merely symptoms of their lifestyle and environment. Through the knowledge of circadian biology and evolutionary medicine, he began to develop a deep understanding of how sleep and metabolism work, and the actionable steps necessary to correct these bodily functions.
