Part 2

You may be wondering: how can your busy lifestyle lead to weight gain and injury. You may be saying, “I’m active, I exercise, and I am always moving or doing. What’s so wrong with that?” For purposes of this story, here is my attempt to make it simple. The nervous system is truly anything but simple.

The nervous system records and distributes information with two main parts: the central and peripheral nervous systems. The Central Nervous System (or CNS) is made up of the brain and the spinal cord and it controls the body’s responses.

The Peripheral Nervous System (PNS) is everything outside of the CNS. Its main function is to connect the CNS to the limbs and organs, serving as a conduit between the brain and the rest of the body.

The two parts of the PNS are the autonomic and somatic. Today, I’m focused on the autonomic, which controls involuntary responses — the everyday responses we have to external stimuli. It is divided into two parts: the sympathetic and the parasympathetic nervous systems.

The sympathetic system is activated during “fight or flight” situations where emotional stress or physical danger looms. The parasympathetic counteracts these responses: relaxing the body, aiding in “rest and digest,” increasing saliva production, and decreasing your heart rate.

 

Our bodies were made with a mechanism referred to as “fight or flight” (the sympathetic nervous system). It’s our human body’s way of protecting itself. Many years ago, we used to forage for food and defend ourselves against enemies. Our bodies were made to help us sense and protect ourselves from danger.

These two parts of our essential make up — fight or rest — are in constant push-pull. While getting excited to hear your daughter is expecting her first child, your body is also trying to calm you.

Here comes the cortisol story we’ve talked about before. Cortisol, “hydrocortisone,” is produced in the adrenal cortex of the brain – or “the adrenals” – to respond to emotional and physiological stress. It sort of protects you from the stress by giving your body the energy to fight the fight. It is highest in the morning to get us out of bed, peaking around 8am, then decreases to its lowest around 3pm. Cortisol is supposed to be short lived. Unfortunately, with excessive stress, cortisol is excreted by the adrenals all day long to protect us from the “fight.” This creates a cascading effect on all of the other systems in your body.

In order to protect the body from the stress, cortisol shuts down our immune system, delivering energy where it is needed most: combating stress. It also stops bone and muscle growth, disrupts your sleep cycle, increases our blood pressure, reduces blood flow, works as an anti-diuretic, adds weight around the waistline, and disrupts the reproductive system. Metabolic – or fat-burning – disturbances occur, making you hungrier for foods that aren’t on your clean diet.

Many other normal body functions are put at risk, too. Increased cortisol leaves blood sugar levels higher; the body gets tired of chronically producing insulin, and it is possible to become insulin resistant and ultimately diabetic. There are serious medical conditions associated with a wide range of manifestations including Cushings and Addison’s Disease, as well as Adrenal Fatigue. They are no joke and should be addressed by a medical doctor. The purpose today is to help you navigate your health through the lens of your nervous system and help you understand that being constantly stressed has serious implications not only for your waistline but for your health and longevity.

Dr. Aviva Romm likens the stress-induced cortisol response system to the national guard, ready to protect your personal boundaries against infection. Cortisol changes the way your brain works so you react on automatic pilot rather than use your own willpower and higher thinking capacities.

The human body is all about constantly repairing itself. Yet under stress, it can’t heal; it’s too busy truly just warding off “disease” or that over-demanding schedule we insist on maintaining. As immunologist and best-selling author of “Healing Spaces” Esther Sternberg says, ” …disease happens when the repair process is not keeping up with the damage process.”

Did you read that? Read it again. Our bodies can’t repair if they are always in a state of stress. How do you think you’ll recover from – or prevent – injury if you are always on the run?

Stay tuned for next week’s post about how your stress directly affects your workouts and your ability to prevent and rehabilitate from injury.

Adrien founded Fitness on the Run in 2004 out of her home. After spending 15 years developing her own personal definition of wellness and watching literally thousands struggle with theirs, in 2019 Adrien founded Alexandria Wellness, the home for the Concierge Wellness Program and Corporate Wellness with Adrien Cotton. Today, “FOR” is home to more than 250 clients, 12 instructors, and hundreds of inspirational success stories. She is passionate about helping others view their fitness as a journey, not a quick fix. Adrien’s recipe for success herself has evolved from a rigid training plan of a 4-5 hard workouts per week to some days getting in her 10,000 steps and her 7.5 hours of sleep and her beloved 5-Minute Flow. Now, she believes the most important ingredient is making small changes for big results, even if it’s only for five minutes a day. Adrien works daily to help clients understand that the three most vital components of any effective fitness program are consistency, sustainability, and fun. Adrien believes we all benefit from being curious about our bodies and our health and that change, or improvement, is always within reach despite what your “inner voice” or others may tell you. She believes her vocation is to help Alexandrians learn the importance of a comprehensive approach to wellness, weight loss, and contentedness with yourself, and that every person has the right to feel good about themselves. Most days, you can find her helping clients with their wellness and listening to FOR client’s success stories.
