In this episode, Dr. Enrique Esteve explains the role of the Epstein-Barr virus in fatigue, viral reactivations, and its relationship with certain autoimmune diseases. We also discuss the importance of sleep, the impact of sleep medications, and the role of muscles in immunity, as well as topics like thyroiditis, histamine, and obstetric antiphospholipid syndrome. A reminder that the body functions as a whole, where immunity, rest, and fertility are deeply connected.
