#Sympathetic Nervous System “Fight or flight” or “Type A’s”
There are 3 basic #SNS Dominant subtypes: Basic, Extreme, & Inefficient SNS Dominant types. The following is a summary of the average SNS Dominant types.
Personality traits vary widely in this group depending on whether they are more analytical vs. emotional. For instance, more emotionally based SNS Dominants are likely to be more volatile and “nervous” whereas the more analytical type does not.
The sympathetic nervous system (SNS) activates the glands and organs that defend the body against attack, whether it is running from a saber toothed tiger or you are struggling with a dreadful job and difficult boss. It is called the fight or flight system and once activated, it directs more blood to the muscles, #adrenals and the brain yet away from the digestive organs and skin. The adrenals pump out #epinephrine while the sympathetic nerve endings throughout the body release #norepinephrine . This system is #catabolic , which simply means that energy is used to prepare for defense, rather than for nourishment, healing, or waste removal. #Sympathetic activity triggers the thyroid and adrenal glands to provide extra energy for fighting or running away. The heart rate and blood pressure also increase, just as the blood flow to the digestive system and kidneys decreases. This process is largely due to the intensified release of stimulating chemicals, known as #neurotransmitters #epinephrine and #norepinephrine . While this activity is critical for survival, those who have chronic activation of the SNS often develop #anxiety, #insomnia , heart racing or disease (heart failure), and adrenal #fatigue . They also have “goose bumps” more frequently than other types and tend to do best in warmer weather. A Sympathetic Dominant Nervous System often leads to significant gastro-intestinal issues due to the poor #digestion of meats and fats. These folks often feel as though food "sits like a rock in my gut". Due to the rising levels of Norepinephrine (the body’s flight or fight neurotransmitter), digestion shuts down to reserve precious resources for survival. Chronic activation can lead many to feel agitated, jittery, wired, & restless as well as prone to sleep disturbances and anxiety. They may also experience the vicious cycle of the “Wired but tired” sensation when eating an inappropriate diet or taking the wrong supplements, which in their case, is filled with sweets and other junk foods or heavy proteins. When a dysfunctional sympathetic nervous system reigns supreme, one may experience anxiety, stress, or feelings of panic, which should normally only occur in response to a perceived threat. Subsequently, they may overreact to even the mildest of daily troubles.
These individuals often start out thin and active yet poor diets—usually filled with sweets and starchy carbs often lead to later weight gain. When busy or stressed, they frequently forget to eat regularly, if at all. They are often pale, do not tolerate cold weather and tend to have colder hands & feet. Such individuals are often impatient and easily frustrated or angered, yet it appears to quickly pass. They often make for volatile partners and bosses, in that they frequently explode; yet minutes later have already moved on. They are also frequently viewed as “intense,” “aloof,” or “bold,” and have a tendency of “sticking their foot in their mouths” by being too aggressive or forward. Nevertheless, #genetic & environmental factors influence this area considerably.
They are also very driven, ambitious, and motivated people who may excel in academics or in high energy vocations that require multi tasking and social interaction. Many also enjoy a stimulating debate or confrontation (attorneys, politicians, generals). When healthy ... ..more
Think “delightful dialogue” with #dopamine since this #neurotransmitter is crucial for happiness, a sense of wellbeing, and language. It’s also involved in #muscle control and function. Dopamine is responsible for #motivation , interest, #mood , #speech , and contentment. It is also associated with positive #stress states such as being in love, exercising, listening to music, and of course, #sex . When you don't have enough dopamine, you may have difficulty initiating or completing tasks. Deficiencies also lead to poor #concentration , little or no energy, and lack of motivation. This could be the culprit if you lack the initiative to study the ... ..more
The human genome is a string of over 3 billion chemical letters that spell out every inherited trait. Although the letters of all our genomes are virtually identical and have little variation, more and more frequently, nature gets a letter wrong, similar to a typo. Scientists call these genetic misspellings SNPs (Pronounced: snips), or single nucleotide polymorphisms, which occur as variations at a single site in DNA. In fact, a SNP is the most frequent variation in the human genome with about 5-10 million of them. Although not all of these disparities contribute to disease. Scientists are now using them ... ..more
