Fight or Flight Concept Updated

 

The old concept of Fight or Flight was helpful in helping to explain the stress response. It’s just not good enough anymore.

Our nervous system is much more complex than that.
Hans Selye gave us his theory on stress and Walter Cannon gave us his concept of fight or flight.

They also talked about the autonomic nervous system with its sympathetic and para-sympathetic branches. The sympathetic speeding things up and the parasympathetic slowing things down. Sounds simple enough. It was relatively easy to explain the concept to people. But, it didn’t explain everything. It also led to some flawed thinking. Many people came to think that sympathetic activation was bad and would lead to negative health outcomes and parasympathetic activation was good and would always lead to positive health outcomes.

This is not a quote from a well know scientist but instead what old people | know used to say “Too much of one thing, is good for nothing”.

Too much sympathetic activation can lead to problems like anxiety and hypertension. Too much sympathetic activation can lead to problems like low energy, depression, and hypo tension (low blood pressure). Another update has to do with additional Fs being added to the original Fight or Fight. Our reactions are not binary. Freezing is a third response. This is the deer in the headlights response or playing dead like an opossum. Sometimes not moving can be helpful. At other times it could be the worst thing for survival, Fawn is a new one for me.

This involves reacting in a way to try to please, to avoid further conflict.

Flow is a more positive reaction. It was described by Mihaly Csikszenemihalyi, in his book Flow: The Psychology of”Optimal Experience. This is what people like athletes describe when they are able to perform at their best under challenging situations during which others might fold and erform poorly. People describe time slowing down and focus ‘expanding rather than norrowing.

Maybe we should be working on regulating our responses instead of turning them off: People don’t want to become relaxed zombies. They want to live effectively.

Risking: Good Idea, Bad Idea | Mental and holistic healthcare practitioner

Certain actions or activities carry risks, whether you are engaged in combat for your country, sky diving, investing in high-risk stocks, as a pioneer exploring unknown territory, or simply going beyond your established comfort zone.

Clearly, there is a distinction between necessary, or calculated risk, versus unnecessary or random risk-taking. By consensus, some risks are considered a healthy aspect of personal development, whereas others have negative consequences.

It would seem not a coincidence that there is, reportedly, a high proportion of prison inmates in the US, exhibiting or diagnosed with ADHD, with symptoms that include: impulsivity, poor judgment, risk-taking, or reckless behavior, with disregard for one’s safety and safety of others, not learning from previous experience and higher recidivism.

The Epidemic of Sleep Deprivation: Anxiety, Stress

 

How many of us lie awake at night, with ruminating thoughts, unable to fall asleep? Or we finally nod off, only to reawaken and cannot get back again.

According to the American Academy of Sleep Medicine, about one in three suffer from Insomnia at least periodically. Insomnia persisting for over a month is considered a chronic condition, affecting 1 in 10.

Night after night, unable to sleep, we may become anxious, or fearful about getting to sleep, making the situation worse. Disturbed sleep is often a reaction to stressors, or trauma, causing the problem to spiral.

According to LENS founder Dr Len Ochs, sleep disturbance may involve a pervasive, underlying CNS dysregulation, characterized by delayed sleep onset, or DFA, nocturnal awakening ( broken sleep), or waking unrefreshed, daytime sleepiness and fatigue.

Disrupted sleep can be a consequence of Anxiety, PTSD, Panic Attacks, chronic stress and tension, emotional, mental or physical pain. LENS therapy can address these multiple factors and conditions by helping patients in regulating their autonomic nervous system and balancing of their EEG.

Alzheimer’s is Preventable

Alzheimer’s Disease – a form of dementia affecting 5.6 million Americans , currently incurable – is preventable, according to The Lancet Neurology, an established medical journal for brain research.

In Dr Joseph Mercola’s interview of board-certified neurologist and nutritional authority, Dr David Perlmutter what it brought out and emphasized is the important role of aerobic exercise and healthy lifestyle choices: that eating a diet high in ‘good’ fats and oils, and low in carbs can positively affect brain health and lower the risk of developing Alzheimer’s.

Dr David Perlmutter is author of the best-selling book, ‘Grain Brain: the Surprising Truth about Wheat, Carbs and Sugar – Your Brain’s Silent Killer.’ In the book, he states: ‘Lifestyle choices, like aerobic exercise, healthy fats, reducing carbs, including whole grains, affect overall brain health, as well as risk of Alzheimer’s.’ Further, says Dr Perlmutter, ‘a hi-carb diet, of which 20% comes from wheat-based food,’ can lead to Dementia, ADHD, Anxiety, Chronic Headaches , Depression and other neurological diseases.

Gluten in wheat leads to gluten-sensitivity and the production of Zonulin in the gut, according to Dr Dasano, a pediatric gastroenterologist and research scientist directing the Center for Celiac Research & Treatment at Mass. General Hospital, Boston. Zonulin is the cornerstone of diseases characterized by permeability of the gut and inflammation in the brain – Alzheimer’s, Autism, Parkinson’s and Attention Deficit Disorders as well as auto-immune diseases’- related to consumption of carbohydrates, says Dr Perlmutter. Dr Fasano’s research shows that reaction to Zonulin is not confined to the 1.85% with Celiac, but is present in 100% of the population.

Brain ripples drop sugar levels in rats [Mental and holistic healthcare practitioner] [Biofeedback]

Ripples of nerve cell activity that lock in memories may have an unexpected job outside of the brain: dropping blood sugar levels in the body.

Soon after a burst of ripples in a rat’s hippocampus, a brain structure that plays a key role in memory, sugar levels elsewhere in the body dipped, new experiments show. The curveball results, reported August 11 in Nature, suggest that certain types of brain activity and blood sugar control – a key part of metabolism – are entwined in surprising and mysterious ways.

“This paper represents a significant advance in our understanding of how the hippocampus modulates metabolism,” says Elizabeth Gould, a neuroscientist at Princeton University who wasn’t involved in the study.

Neural shudders are called sharp-wave ripples zig and zag in the brains of people as they learn new things and draw memories back up (SN: 9/14/19, p.14). Ripples also feature prominently during deep sleep and are thought to accompany the neural work of transforming short-term knowledge into long-term memories.

Neuroscientist David Tingley, now at Harvard University, wondered whether these signals might also change something outside of the brain. Tingley and colleagues fitted continuous glucose monitors onto the backs of eight rats. The researchers simultaneously measured the rats’ brain waves with electrodes implanted in the hippocampus.
