Stress and Disease: Understanding the Autonomic Nervous System and Your Body's Priority System

This podcast episode, "User Manual for Humans Part Two," delves into the fundamental link between stress and various diseases, emphasizing a redefinition of health. Dr. Ekberg posits that true health is not merely the absence of disease or symptoms, but rather when "everything is working the way it's supposed to," specifically highlighting the nervous system's ability to appropriately process environmental information. He introduces a hierarchical model of body tissues—passive (bone, fat), active (muscle, heart), and regulatory (brain and nervous system)—asserting that the brain and nervous system are the ultimate source of all bodily function and, consequently, all problems.

The core of the discussion revolves around the autonomic nervous system (ANS) and its two branches: the sympathetic (fight, flight, stress, defense) and parasympathetic (feed, breed, health, healing). A critical distinction is made using the analogy of a seesaw, illustrating that these two systems operate in an inverse relationship: when one increases, the other decreases. This means the body cannot simultaneously be in a state of defense and a state of optimal health or healing. The speaker stresses that the body is constantly making a choice between these two states, allocating resources accordingly.

A key argument presented is the body's inherent priority system: defense (sympathetic response) always comes first. This is because immediate survival takes precedence; if one doesn't survive the present moment, long-term health becomes irrelevant. This physiological prioritization has profound implications: whenever the body is under stress, its capacity for healing is significantly diminished or completely inhibited. Resources, primarily transported by blood (oxygen, glucose, nutrients), are diverted to support the defense mechanism, away from internal repair and maintenance systems.

The broader implication is that chronic stress, by constantly activating the sympathetic nervous system, directly contributes to the development and persistence of common ailments like pain, weight issues, high blood pressure, cholesterol problems, and diabetes. The episode encourages listeners to understand these fundamental concepts to better manage their health, suggesting that addressing the root cause of dysfunction in the nervous system, rather than just managing symptoms, is crucial for achieving true well-being and preventing disease.

"health is when everything is working the way it's supposed to"

"when your nervous system can receive and appropriately process all information in your environment"

"the brain and nervous system is where all function is and it's where all problems are"

"if there's something in your body if you have a symptom there's something in your brain that isn't working"

"everything in your body that happens without you thinking about it is handled by your autonomic nervous system"

"when one side increases the other side decreases always"

"if one side is defense and one side is health that means we can't do both at the same time"

"the hierarchy the priority in the body is defense sympathetic always always comes first always"

"whenever we have a sympathetic response whenever we have a stress response we cannot heal at the same time at least not completely or or adequately"

"what carries the resources in the body well it's the blood right"
