Stress! We have all heard this word and in some cases it is becoming a popular mantra. In my much younger days “stress” was often a term used for a difficult job. Now we hear this word all the time to describe even what some might term as a “relaxing” day. How did we become so stressed in this life and how is this affecting our body. Can certain relaxing exercises or just sitting all day cause stress to a body?
The first thing that we need to define is the word stress. Stress means
a state of mental or emotional strain or tension resulting from adverse or very demanding circumstances.
give particular emphasis or importance to (a point, statement, or idea) made in speech or writing.
subject to pressure or tension.
It has often been my thought that the majority of the world’s population is so stressed because we no longer take extended amounts of time just letting our mind relax. The human body has often interested me and the more I learn about how our body tries to compensate with the treatment we give it the more it affirms my strong belief in a loving Creator.
When we are sleeping at night our bodies are not resting as much as one might think, instead it has to process and manufacture all the things that you put into it or do to it. We live in a constant state of stress and anxiety because (my personal belief) there are very rare moments when there is absolute peace and quiet so your mind can process everything you have put into it and have done.
My own personal experience that I was like to share so that others will be warned not to repeat: due to actions directed towards myself and my siblings I maintained many years of negative thinking. Even in moments of “quiet” time I spent much time reliving the anger, pain and disappointment of my life. I also worked very physical jobs in the nursing field which added more “stress” to my body. I drove to work with the radio blasting, would come home, talk or listen to TV which reiterated the anger that I had.
When I had moments on the weekend for my “mind” to relax this led to more “stress” because there was not a proper outlet for all these thoughts and emotions. I had not learned how to deal properly with my anger and negative thinking. I have recently taken notice that the majority of my “internal” talk is I am mad about this or that….. Someone didn’t do what I wanted them to do therefore, I am upset with them regarding it…This will feed the negative thinking.
1. Stress creates free radicals that kill brain cells.
Cortisol creates a surplus of the neurotransmitter glutamate.
Glutamate creates free radicals — unattached oxygen molecules — that attack brain cells much in the same way that oxygen attacks metal, causing it to rust.
Free radicals actually punch holes in the brain cell walls, causing them to rupture and die.
Stress also indirectly contributes to other lifestyle habits that create more free radicals.
If stress causes you to lose sleep, eat junk food, drink too much alcohol, or smoke cigarettes to relax, these are contributing to your free radical load.
2. Chronic stress makes you forgetful and emotional.
Memory problems may be one of the first signs of stress you’ll notice.
Misplaced keys and forgotten appointments have you scrambling, further adding to your stress.
If you find all this stress is making you more emotional too, there’s a physiological reason for this.
Studies show that when you’re stressed, electrical signals in the brain associated with factual memories weaken while areas in the brain associated with emotions strengthen.
3. Stress creates a vicious cycle of fear and anxiety.
Stress builds up an area of your brain called the amygdala.
This is your brain’s fear center.
Stress increases the size, activity level and number of neural connections in this part of your brain.
This makes you more fearful, causing a vicious cycle of even more fear and stress.
4. Stress halts the production of new brain cells.
Every day you lose brain cells, but every day you have the opportunity to create new ones.
Brain-derived neurotrophic factor (BDNF) is a protein that’s integral in keeping existing brain cells healthy and stimulating new brain cell formation.
It can be thought of as fertilizer for the brain.
BDNF can offset the negative effects of stress on the brain.
But cortisol halts the production of BDNF resulting in fewer new brain cells being formed.
Lowered levels of BDNF are associated with brain-related conditions including depression, OCD, schizophrenia, dementia, and Alzheimer’s disease.
5. Stress depletes critical brain chemicals causing depression.
Your brain cells communicate via chemicals called neurotransmitters.
Chronic stress reduces levels of critical neurotransmitters, especially serotonin and dopamine.
Low levels of either of these neurotransmitters can leave you depressed and more prone to addictions.
Serotonin is called the “happy molecule.” It plays a large role in mood, learning, appetite control, and sleep. Women low in serotonin are prone to depression, anxiety, and binge eating. Men, on the other hand, are more prone to alcoholism, ADHD, and impulse control disorders.
Dopamine is the “motivation molecule, it is in charge of your pleasure-reward system. Too little dopamine can leave you unfocused, unmotivated, lethargic, and depressed. People low in this brain chemical often use caffeine, sugar, alcohol, and illicit drugs to temporarily boost their dopamine levels.
Serotonin-based depression is accompanied by anxiety and irritability, while dopamine-based depression expresses itself as lethargy and lack of enjoyment of life.
6. Stress puts you at greater risk for mental illnesses of all kinds.
The root cause of most mental illnesses is not yet understood.
If answers are ever found, the causes will most likely be a complex variety of factors.
Recent research has discovered physical differences in the brains of people with stress disorders.
Their ratio of the brain’s white matter to gray matter is higher. Stress predisposes you to developing a variety of mental illnesses including anxiety and panic disorders, depression, PTSD, schizophrenia, bipolar disorder, drug addiction and alcoholism.
7. Stress makes you stupid.
Stress can cause your brain to seize up at the worst possible times — exams, job interviews, and public speaking come to mind. This is actually a survival mechanism. If you’re faced with a life and death situation, instinct and training overwhelm rational thought and reasoning. This might keep you from being eaten by a tiger, but in modern life this is rarely helpful.
Stress impairs your memory and makes you bad at making decisions. It negatively impacts every cognitive function.
8. Chronic stress shrinks your brain.
Stress can measurably shrink your brain. Cortisol can kill, shrink, and stop the generation of new neurons in the hippocampus, the part of your brain that stores memories. The hippocampus is critical for learning, memory and emotional regulation, as well as shutting off the stress response after a stressful event is over.
Stress also shrinks the prefrontal cortex. This negatively affects decision making, working memory, and control of impulsive behavior.
9. Stress lets toxins into your brain.
Your brain is highly sensitive to toxins of every kind.
The blood-brain barrier is a group of highly specialized cells that acts as your brain’s gatekeeper.
This semi-permeable filter protects your brain from harmful substances while letting needed nutrients in. Stress makes the blood-brain barrier more permeable, in effect making it leaky.
This lets things into the brain you don’t want there such as pathogens, heavy metals, chemicals, and other toxins.
Having a leaky blood-brain barrier is associated with brain cancer, brain infections, and multiple sclerosis.
10. Chronic stress increases your risk of dementia and Alzheimer’s.
One of the most worrying effects of stress on the brain is that it increases your risk for dementia and Alzheimer’s.
Being diagnosed with Alzheimer’s disease is the #1 health fear of American adults, even more so than cancer. Alzheimer’s is now the sixth leading cause of death.
One in three US seniors will die with Alzheimer’s or other forms of dementia. And it’s the most expensive disease in the country. There is no simple “magic bullet” to prevent Alzheimer’s.
Common sense advice includes eating a healthy diet low in sugar and high in brain-healthy fats, getting physical exercise, not smoking, staying mentally active, avoiding toxic metal exposure, and minimizing stress.
It’s been found that stress, particularly stress that occurs in midlife, increases risk of Alzheimer’s. Anxiety, jealousy and moodiness in middle age doubles your risk of developing Alzheimer’s.
Chronic stress and elevated cortisol contributes to dementia in the elderly and hastens its progression. (44)
11. Stress causes brain cells to commit suicide.
Stress leads to premature aging on a cellular level, causing cells in both your body and your brain to commit suicide prematurely.
To understand how this happens, we need to take a look at a part of your chromosomes called telomeres.
You may recall from high school biology that when a cell divides, it passes on the genetic material to the next cell via chromosomes.
Telomeres are protective endcaps on our chromosomes similar to the plastic tips on shoelaces. (Telomeres are shown in contrasting colors to the rest of the chromosome in this image.)
Every time a cell divides, the telomeres get a little shorter. When they reach a critically shortened length, they tell the cell to stop dividing, acting as a built-in suicide switch.
Subsequently the cell dies.
Shortened telomeres lead to atrophy of brain cells and longer telomere length leads to the production of new brain cells.
Telomere length may be the most important indicator of biological age and disease risk.
Some researchers believe it’s a better predictor of your risk for age-related diseases like Alzheimer’s, heart disease, diabetes, and cancer than conventional diagnostic tools.
12. Chronic stress contributes to brain inflammation and depression.
A little-known fact is that the brain has its own immune system.
Special immune cells called microglia protect the brain and spinal cord from infections and toxins. Unfortunately, a microglial cell has no on or off switch, so once it is activated, it creates inflammation until it dies.
Chronic stress is one of the factors that increases the risk of activating your microglia, thus producing brain inflammation. It’s generally believed that depression is caused by serotonin deficiency, but there’s a growing body of evidence that brain inflammation is the root cause of depression instead.
This theory is called the “cytokine model of depression.”
Activated microglia produce cytokines — proteins that turn on the inflammation response in the brain. Cytokine production is linked to depression including major depressive disorder and risk of suicide.
It’s also associated with anxiety, memory loss, and inability to concentrate, as well as some serious disorders including schizophrenia, Parkinson’s, and Alzheimer’s.
On Top of All That …
Chronic stress destroys your happiness and peace of mind.
It wears you down mentally and emotionally, and saps the joy from life.
Some side effects of stress that impact your mental well-being include:
- excessive worry and fear
- anger and frustration
- impatience with self and others
- mood swings, crying spells or suicidal thoughts
- insomnia, nightmares, disturbing dreams
- trouble concentrating and learning new information
- racing thoughts, nervousness
- forgetfulness, mental confusion
- difficulty in making decisions
- feeling overwhelmed
- irritability and overreaction to petty annoyances
- excessive defensiveness or suspicion
- increased smoking, alcohol, drug use, gambling or impulse buying
It’s no fun experiencing these stress symptoms. It’s no picnic for those around you either.
5 Simple Steps to Help a Chronically Stressed Brain
We wouldn’t leave you with all this bad news with no solutions.
Minimizing stress and protecting your brain against its effects is easier than you might think. Here are five simple tips to stop stress in its tracks and overcome its harmful effects on your brain.
- Build a deeper relationship with your Heavenly Father. We were created with a need for our Heavenly Father and the peace of being in His will give you a sense of purpose beyond anything you could have dreamed.
- Stop free radical damage by eating a diet high in antioxidant-rich foods like fruit, vegetables, dark chocolate, and green tea.
- Increase levels of brain-boosting BDNF by getting daily physical exercise. It doesn’t have to be strenuous. Walking is excellent, as well as relaxing physical exercise such as light weights or low intensity cardio.
- Start a daily meditation practice, such as spending quiet time in prayer. Meditation not only reduces stress, it’s a proven way to keep your brain young by keeping telomeres long. Meditation is also the best tool for learning how to master your thoughts. Stress does not come from events in your life as much as it comes from your thoughts — your automatic negative reactions and cognitive distortions — about these events.
- Look into taking an adaptogenic herbal remedy. Adaptogens increase your resilience to stress while supporting overall health. They promote balance between feeling energetic and feeling calm. Examples of adaptogens include ginseng, holy basil, Arctic root, and bacopa.
Chronic stress may seem to be an unavoidable part of life, but these proactive steps will definitely reduce its wear and tear on your brain.”
How we react to situations can either improve or cause further health problems in our bodies. If might behoove us to consider that our health disorders could mainly be caused by all the internal “stress” to our bodies. We can change our eating to include boat loads of diets but if we don’t stop the constant drain to our organs and brain the change will only be temporary or non-existent.
Start today and take some time to relax, don’t think about anything. If you want to focus on something memorize scripture verses that you can say while you relaxing. Speak words of life all throughout your day!! When a negative thought comes up change your mind to words of the Heavenly Father.
