Manic Monday- The Why's of Exhaustion and Brain Damage!

I'm wondering today...can exhaustion build up in your body??

Do we on a daily basis build levee systems to prevent it from seeping out or busting through and then once it does it floods your system?  

Does our own stress hormones that flood our system with fight or flight chemicals stay in our system until our guard has let down?

I have to know the process.  People have told me to reduce stress to help weight loss, increase memory, energy and overall health.  Why?  How does it all connect?  Where's the emergency brake to stop the stress? Here are some of my attempts at understanding what stress does to my brain and my body.  

This is one website that I found. http://www.youramazingbrain.org.uk/brainchanges/stressbrain.htm


Our brain perceives a threat and it sends immediate nerve signals down to the adrenal glands. 
"Once released, adrenaline increases the amount of sugar in your blood, increases your heart rate and raises your blood pressure (and has many other actions)."

Then the hypothalamus tells another part of the brain to release a stress hormone-cortisol.  
"Cortisol is very important in your stress response - keeping your blood sugar and blood pressure up to help you escape from danger."


According to many sources, extended periods of cortisol in babies, children and adults kills brain cells.

"Cortisol has been shown to damage and kill cells in the hippocampus (the brain area responsible for your episodic memory) and there is robust evidence that chronic stress causes premature brain aging."

Basically cortisol excites the brain to death. "The cortisol released in stress travels into the brain and binds to the receptors inside many neurons..."

New brain cells are made at amazing rates during early childhood but the adult does make new ones.  Joe Herbert's lab in Cambridge has showed that cortisol dramatically decreases the rate new brain cells are made.

Some of my research shows that chronic stress leads to depression, heart disease, obesity, diabetes, sleep loss and much more.

In fact the longer that “The longer your stress responses are activated, the harder it is to shut them off,” says Bell, “Chronic stress causes significant disruptions to the normal functioning of the body and mind, and we simply aren’t built to sustain these effects.”

All of these racing hormones wears us out.  Wears out our brain and our bodies.  More importantly it wears down our families.

I guess the point is that we need to have a discussion about the affects of stress on our children, our health, our families and our world.  Please join the discussion and share your thoughts!!!!

Starting a Journey

September 3, 2010 Originally posted How to Begin a Journey 1. Pick a destination or simply start. 2. Plan a detailed itinerary or just take the first step. 3. Pack everything or travel lightly. I am choosing to just begin. To leave behind the baggage, pick up a day pack, and go. Several nights before we moved to Ogallala, I was praying about the transition when I heard that still, small voice of God. In that moment, I knew He heard my Heart's Cry. He hears every whispered plea, every unspoken longing. If I truly sit with that truth, it humbles me. What courage, boldness, passion, and decisiveness I have when I remember: He never leaves or forsakes me. He provides for my every need according to His riches in glory. My hope is to encourage you He hears your Heart's Cry too.

1940 Canned Apple Butter: Family Root Cellar

I loved exploration as a child.  From opening the door and going down the stairs to get something from my Grandma's root cellar or exploring old homesteads while checking cows.  I credit my Mom with teaching us to appreciate those things that represented the people who had gone before us. When I moved with my husband and boys to a house on the family ranch-I began exploring immediately.  This was the house my Aunt and Uncle lived in during my childhood.  My Grandparents had lived there and many other families dating back to 1900 when it was built.   With two little boys in tow, I made my way to the root cellar and found a treasure cove.  Old text books belonging to the original family who had been a teacher, the original medicine cupboard, tools, trash and memorabilia.   I felt like an archeologist sifting through layers of debris representing generations and culture.  And I was.  I hauled truckloads of trash to the dump (some...

Diabetes-Opened to Disease OR Open to Connecting to my Strengths

I've tried living in denial for two years after the big D diagnoses was handed over.  Honestly, I just don't want to talk about it.  Outwardly seemly calm and disconnected from it.  Inwardly terrified. As a plant that is stressed is open to disease, injury and death so to our bodies are.  I opened myself up to this.  Stress, lack of sleep, bad nutrition, overweight and lack of exercise.  For some reason I believed that if I ran fast enough and worked hard enough, I would outrun my family genes.  The tiny room in the back of my brain locked with a key has kept the fear of this disease at bay even though I could hear its screaming when life quieted down. My Aunt died piece by piece to this disease.  First a heart attack and quadruple by-pass.  Then a toe.  Next a foot.  Legs came next along with more heart attacks.  Kidneys shutting down.  She died very young. When I was little, my Aunt Ally gave herself s...
