Ask most anyone and they will probably agree with you that stress is not good…and then they go on telling you how stressed out they are all the time. In today’s world we have to take action to stop stress from taking over our lives (and taking it in the wrong direction). First let’s look at what is really going on inside of us.
Your autonomic nervous system (ANS) is an involuntary response system built into your body that controls many of your organs and muscles (heart, lungs, glands, stomach, blood vessels). We don’t even know it is working most of the time except when maybe we feel it in extreme situations (increased HR). What it does, is very important. You may also recognize it as the system that controls your “Fight or Flight” response (what keeps you alive when you need to fight off your attacker or run away from a dangerous situation). The 2 main parts of the ANS are comprised of the:
The Sympathetic Nervous System (SNS) is responsible for getting us ready for action from an oncoming “stressor” (whatever that may be). It is our innate primal protective system that was meant to be used in times of stress that would cause harm to us. When it kicks in, it does the following:
The Parasympathetic Nervous System is when there is no perceived threat (or stressor) and the body can relax and get back to normal function. The PNS does the following:
Everyone has heard of the hormone called Cortisol, it’s a blood sugar hormone responding to stress and goes up when the SNS is activated (in response to adrenaline/noradrenaline). It’s a natural hormone that is actually needed to even wake up! As we wake up at 8am, our cortisol level is at it’s highest converting liver glycogen into glucose and increasing blood glucose levels to give us energy. (Hence if you ever see anyone suffering from Chronic fatigue or can’t wake up in the morning, chances are their cortisol output is very small….as sign of burnout from too much SNS activation/chronic cortisol production/adrenal fatigue).
“We live longer than our forefathers; but we suffer more from a thousand artificial anxieties and cares. They fatigued only the muscles, we exhaust the finer strength of the nerves.” ~ Edward George Bulwer-Lytton
What we want to do for optimal health and weight loss is to manage sources of chronic or excessive cortisol as it can lead to increased insulin resistance, obesity, inflammation, muscle loss, and a host of other bad things listed above (a distinct sign of cortisol and it’s related insulin resistance role on fat gain, is seeing it more in our “problem” areas).
Cortisol has a half life of about 1hour, so it can go down if we give it a chance. Our natural rhythms should be higher cortisol in the morning, and then shifting into lower and lower amounts until we hit bedtime around 10pm where our cortisol is so low (along with blood glucose) that we are tired and need to go to sleep. Then the cycle starts over again.
Unfortunately, this cycle is messed up with alot of people and unless it is corrected and controlled, some may never see the weight loss they want because of all the other hormonal things going wrong in the body.
Looking at everything above, you can see why we want like to have a balance between PNS and SNS activation (as that is what helps us digest food, detox the body, increase organ function, boosts the immune system, reduces inflammation, builds muscles, etc..etc).
SNS is meant for shorts bursts only, as once the fight or flight is over…then the body can slow down, shift over to the PNS response and heal and repair itself as needed. The problem is not with the short bursts of stress, but the chronic stress (ongoing for extended periods of time) in our lives…the ones that keep the SNS excessively activated all day and do not allow the PNS to take over.
Chronic SNS can lead to reduced digestion, improper organ function, malabsorption of essential vitamins and minerals (as part of the digestive process), lowered immune function, muscle breakdown and loss, sickness, increased inflammation, etc..etc. Not a road we want to go down I would assume for all of us.
“Stress is an ignorant state. It believes that everything is an emergency.” ~ Natalie Goldberg
So let’s wrap this up with a list of what the most common chronic stress factors are and things you can do to control it. Remember that it’s up to you to identify and control what comes in and out of your life. You may think you are getting away with it now, but if you keep the SNS on and limit the PNS activity, then you are most certainly heading down a road of illness and disease.
