"Many of the supplements currently promoted for weight loss have sympathomimetic effects; in other words, they are compounds from plants, including herbs, or other natural compounds that stimulate the sympathetic nervous system, and they carry the same risks as prescription drugs that stimulate the sympathetic nervous system. EPHEDRA One such supplement is the Chinese plant ma huang, which contains ephedra, a compound similar to ephedrine, which stimulates the sympathetic nervous system." - J. Douglas Bremner, Before You Take that Pill: Why the Drug Industry May Be Bad for Your Health (Get the book.)

"With the stress response, the sympathetic nervous system dominates. With the relaxation response, the parasympathetic nervous system dominates. The parasympathetic nervous system controls bodily functions such as digestion, breathing, and heart rate during periods of rest, relaxation, visualization, meditation, and sleep. Although the sympathetic nervous system is designed to protect against immediate danger, the parasympathetic system is designed for repair, maintenance, and restoration of the body." - Michael T. Murray and Michael R. Lyon, Hunger Free Forever: The New Science of Appetite Control (Get the book.)

"With lie detector tests, the machine picks up any increase in the electrical conductivity of the skin, which is caused by increased activity of the sweat glands, which in turn are governed by the sympathetic nervous system. As doctors can measure electrical activity of the heart and brain with ECG (electrocardiogram) and (EEG) electroencephalogram) machines, respectively, so too can the lie detector record increased electrodermal activity. Higher EDA readings show that the sympathetic nervous system, which governs emotional states, is in overdrive." - Lynne Mctaggart, The Field - The Quest for the Secret Force of the Universe (Get the book.)

"The nervous system is made up of the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system slows down certain functions, whereas the parasympathetic nervous system stimulates organs and tissues. They act in harmony with each other. For example the sympathetic nervous system opens or dilates the bronchial tubes and the parasympathetic closes or constricts them. If there is an allergic reaction to one or both of these parts of the nervous system, an imbalance can cause too much dilation or constriction." - Ellen W. Cutler, Winning the War Against Asthma and Allergies (Get the book.)

"This type of stress mechanism is activated by increased activity of the sympathetic nervous system, which normally acts on the basis of "fight or flight." Many scholars have supported the close relationship between stress (induced by sympathetic nervous system stimulation) and the effort that accompanies visual attention (see Kahnemann, 1973; Libby et al., 1973; Pribram & McGuinness, 1975). This type of stress occurs during high cognitive processes as described in Hess and Polt, 1964; and Beatty and Wagoner, 1978." - David De Angelis, The Secret of Perfect Vision: How You Can Prevent and Reverse Nearsightedness (Get the book.)

"The ANS has two branches: the sympathetic nervous system that prepares the body for a "fight or flight" reaction, and the parasympathetic nervous system that prepares the body for eating, digestion, and sex. When the body gets ready to run or fight, digestion stops, sexual arousal withers, heart rate and blood pressure zoom, and the adrenal gland pumps out two hormones: adrenalin, which improves alertness and further turns on the cardiovascular system, and a variant of cortisone called Cortisol, which works to release the body's major fuel, glucose, from its storage reservoir in the liver." - Benjamin H. Natelson, M.D., Your Symptoms Are Real: What to Do When Your Doctor Says Nothing Is Wrong (Get the book.)

"Stress, as I mentioned above, is controlled by your sympathetic nervous system. You have control over the inputs that cause stress, but you have no control over the response itself. If you perceive stress, your body will react. Relaxation, on the other hand, is something you can control. It is governed by your parasympathetic nervous system, so you can consciously engage "the relaxation response," as I will discuss below. Chronic stress affects all of your autonomic functions negatively, but relaxation helps balance all them.These functions include: 1." - Mark Hyman MD, The UltraMind Solution: Fix Your Broken Brain by Healing Your Body First (Get the book.)

"It, in turn, has two components: the sympathetic nervous system (SNS), which causes the arousal responses previously described, and the parasympathetic nervous system (PNS), which calms and relaxes the body. Most stress management techniques, including meditation and biofeedback, aim to induce a positive parasympathetic state by calming down an SNS constantly in overdrive." - Stephen Sinatra, M.D. and James C., M.D. Roberts, Reverse Heart Disease Now: Stop Deadly Cardiovascular Plaque Before It's Too Late (Get the book.)

"The nervous system is made up of the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system slows down certain functions, whereas the parasympathetic nervous system stimulates organs and tissues. They act in harmony with each other. For example the sympathetic nervous system opens or dilates the bronchial tubes and the parasympathetic closes or constricts them.

Cutler, Winning the War Against Asthma and Allergies (Get the book.)

"A polygraph reading can offer evidence of stress to the sympathetic nervous system even before the person being tested is consciously aware of it. In 1966, the state-of-the-art technology consisted of a set of electrode plates, which were attached to two of a subject's fingers, and through which a tiny current of electricity was passed. The smallest increases or decreases in electrical resistance were picked up by the plates and recorded on a paper chart, on which a pen traced a continuous, serrated line." - Lynne McTaggart, The Intention Experiment: Using Your Thoughts to Change Your Life and the World (Get the book.)

"Additional studies have also revealed that the sympathetic nervous system (SNS) activation is transient [67]. Other work noted transient significant elevations of epinephrine (81 %) and norepinephrine (76%) 30 minutes after capsaicin ingestion (30 mg) relative to control treatment, but this was not associated with an additional effect on thermogenesis [70]." - Ann M. Coulston and Carol J. Boushey, Nutrition in the Prevention and Treatment of Disease (Get the book.)

"Many scholars have supported the close relationship between stress (induced by sympathetic nervous system stimulation) and the effort that accompanies visual attention (see Kahnemann, 1973; Libby et al., 1973; Pribram & McGuinness, 1975). This type of stress occurs during high cognitive processes as described in Hess and Polt, 1964; and Beatty and Wagoner, 1978. The basis of the near-point stress theory is the negative adaptation of refractive system to ever-closer and stressing engagement—that is, that modern people engage in many near-distant activities." - David De Angelis, The Secret of Perfect Vision: How You Can Prevent and Reverse Nearsightedness (Get the book.)

"Nothing more abrasively ramps up our sympathetic nervous system than constantly thinking about being under attack or being hurt, and responding as if danger lurks around every corner. Blood pressure and heart rate jump up, digestion shuts down, and the immune system prepares for battle. When this becomes a way of life, we're stuck in the lower-brain functions of reacting, with a direct impact on brain regions that secrete chemicals into the bloodstream. When these chemicals are produced continually, they can negatively affect many organs." - Rick Foster, Greg Hicks, M.D., Jen Seda, Choosing Brilliant Health: 9 Choices That Redefine What It Takes to Create Lifelong Vitality and Well-Being (Get the book.)

"A lie detector is sensitive to the slightest change in the electrical conductivity of skin, which is caused by increased activity of the sweat glands, which in turn are governed by the sympathetic nervous system. The polygraph galvanic skin response (GSR) portion of the test displays the amount of the skin's electrical resistance, much as an electrician's ohmmeter records the electrical resistance of a circuit. A lie detector also monitors changes in blood pressure, respiration, and the strength and rate of the pulse." - Lynne McTaggart, The Intention Experiment: Using Your Thoughts to Change Your Life and the World (Get the book.) "He administered shocks to himself, while a volunteer, isolated in a different room and hooked up to an array of medical gadgetry, was being monitored to see if his sympathetic nervous system somehow picked up Tart's reactions. Whenever Tart jolted himself, the receiver registered an unconscious empathetic response in decreased blood volume and increased heart rate—as though he were also getting the shocks.8 Another fascinating early study had been carried out with identical twins." - Lynne McTaggart, The Intention Experiment: Using Your Thoughts to Change Your Life and the World (Get the book.)

"These are mild sympathetic nervous system stimulants that are sold over the counter, such as those people use to keep awake when they have to drive. In some instances I'm sure there are people who take them as a way of counteracting depression." After amphetamines, the tricyclic antidepressants were introduced. Dr. Goldwag explains, "They're called tricyclic because of their chemical structure, which is a triple cycle. There are a whole bunch of them now on the market. The newer group of medications are those that inhibit the enzymes that break down serotonin." - Gary Null and Amy McDonald, The Food-Mood Connection: Nutrition-based and Environmental Approaches to Mental Health and Physical Wellbeing (Get the book.)

"THE CASE Anxiety is a natural reaction to a threat that happens at a certain point in the stress response, when the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis shift into high gear. When you're facing an upcoming speech or a brewing confrontation with your boss, anxiety sharpens your attention so you can meet the challenge. The physical symptoms range from feeling tense, jittery, and short of breath to experiencing a racing heart, sweating, and, in the case of full-blown panic attacks, severe chest pains. Emotionally, what you feel is fear." - John J. Ratey, MD, Spark: The Revolutionary New Science of Exercise and the Brain (Get the book.)

"Braud and Schlitz selected a group of highly nervous people, as evidenced by high sympathetic nervous system activity, and another calmer group. Using a similar protocol to the staring studies, Braud and Schlitz by turns tried to calm down members of both groups. Success or failure would be measured again by a polygraph tracing of a person's electrodermal activity. The volunteers were also asked to participate in another experiment, in which they'd attempt to calm themselves down with standard relaxation methods." - Lynne Mctaggart, The Field - The Quest for the Secret Force of the Universe (Get the book.) "Taking these readings can give you a measure of unconscious response, when the sympathetic nervous system is stressed before the person being tested is even consciously aware of it. By the same token, low levels of EDA would be indicative of little stress and a state of calm ?the natural state of truth telling. Braud launched his human experimentation with what would become one of his signature studies: the effect of being stared at." - Lynne Mctaggart, The Field - The Quest for the Secret Force of the Universe (Get the book.)

"Braud then asked the participants to examine one of their own tracings and to attempt to influence it, by sending an intention either to calm down or to activate their own sympathetic nervous system at that earlier point in time. The other tracings of the participants, which were not exposed to mental influence, were to act as controls. Later, when he compared the tracings with the controls, he discovered that those tracings that were exposed to the volunteers' own retroinfluence were calmer than the controls. Overall, these studies achieved a small, significant effect size (0." - Lynne McTaggart, The Intention Experiment: Using Your Thoughts to Change Your Life and the World (Get the book.)

"Higher EDA readings show that the sympathetic nervous system, which governs emotional states, is in overdrive. This would indicate stress, emotion or mood swings - any sort of heightened arousal ?which is more likely if someone is lying. These are often referred to as 'fight or flight' responses, which rise and become more pronounced when we face something dangerous or upsetting: our hearts race, our pupils dilate, our skin tends to sweat more and blood drains from our extremities to go to the sites in the body where it is most needed." - Lynne Mctaggart, The Field - The Quest for the Secret Force of the Universe (Get the book.)

"Kopp [149] suggests that consumption of a high-glycemic-index diet may create a chronic state of postprandial hyperinsulinemia, sympathetic nervous system overactivity, and vascular remodeling of renal vessels leading to chronic activation of the renin-angiotensin-aldosterone system and development of essential hypertension. Although logical, the relationship of a high carbohydrate diet to high BP has not been consistent in all studies. Very few studies have been designed specifically to investigate the impact of the quantity or type of carbohydrate intake on BP." - Ann M. Coulston and Carol J. Boushey, Nutrition in the Prevention and Treatment of Disease (Get the book.)

"One part, the sympathetic nervous system, is responsible for the stress response. It slows things down, causes you to store fat, decreases your metabolism, increases your blood sugar, and leads to heartburn or reflux (where food moves up the digestive tract when it is supposed to go down) and constipation (where food stays where it is instead of moving through). The other part is called the parasympathetic nervous system and is responsible for the relaxation response. It makes you digest your food, keeps things going in the right direction, increases fat burning, and lowers your blood sugar." - Mark Hyman, Ultra-Metabolism: The Simple Plan for Automatic Weight Loss (Get the book.)

"Potential mechanisms for the effect of weight loss on BP include suppression of sympathetic nervous system activity, lowered insulin resistance, normalization of BP regulating hormones [186], decreased body sodium stores, decreased blood volume and cardiac output, and reduction of salt sensitivity [187-189]. a. Observational Studies. Several observational studies have reported a positive relationship between several indices of body weight or body fatness with BP [44, 190-194]. b. Intervention Studies." - Ann M. Coulston and Carol J. Boushey, Nutrition in the Prevention and Treatment of Disease (Get the book.)

"This is directly working with the nervous system of the body, very, very gently—it almost doesn't look like they're doing anything—so it's a nice treatment for children. The sympathetic nervous system causes the release of chemicals in our body that make us more hyper and sometimes osteopathic manipulation can help slow that down and get the nervous system more in balance." Many practitioners, myself included, reserve our severest criticism for the drug industry, using the case of Ritalin as a prime example." - Gary Null and Amy McDonald, The Food-Mood Connection: Nutrition-based and Environmental Approaches to Mental Health and Physical Wellbeing (Get the book.)

"Stress—A response of the sympathetic nervous system that arises when there is an unacceptable disparity between your expectations/needs and what you actually experience. Stress activates the sympathetic leg of the nervous system and the release of stress hormones that amp up production of adrenaline and divert blood flow to the large muscles. The body needs this power because it "thinks" it has to run away from or fight something. This is the so-called fight or flight response." - Rick Levy and Lou Aronica, Miraculous Health: How to Heal Your Body by Unleashing the Hidden Power of Your Mind (Get the book.)

"Adrenaline is produced to reinforce the sympathetic nervous system's effect on the body. Its effect is most noticeable as the "fight or flight" response when the body is under physical or emotional stress. REPRODUCTIVE SYSTEM The reproductive glands include the ovaries in the female, and the testes in the male. The ovaries produce ova, or eggs, during the reproductive part of a female's life, and the hormones estrogen and progesterone, which promote the production of feminizing cells in the female body." - Ron Garner, Conscious Health: A Complete Guide to Wellness Through Natural Means (Get the book.)

"EPHEDRA One such supplement is the Chinese plant ma huang, which contains ephedra, a compound similar to ephedrine, which stimulates the sympathetic nervous system. Ephedra increases heart rate, blood pressure, and energy expenditure, stimulating beta-1 and beta-2 adrenergic sympathetic receptors. Ephedra is often combined with caffeine as a weight-loss supplement. Ma huang is also combined with guarana, a Brazilian plant with a high caffeine concentration, and promoted as a weight-loss supplement." - J. Douglas Bremner, Before You Take that Pill: Why the Drug Industry May Be Bad for Your Health (Get the book.)

"It also helps patients lose Without getting into the complex biochemistry of the sympathetic nervous system, understand that stress can elevate hormones that in turn contribute to excessive insulin and blood sugar. Biofeedback, stress reduction, and meditation have been shown to reduce a hormone that stimulates many of the physiological processes that can aggravate or contribute to PCOS. Depression frequently accompanies PCOS, perhaps because good mood is one of the serious casualties of hormone imbalances." - Jonny Bowden, Ph.D., C.N.S., The Most Effective Natural Cures on Earth: The Surprising, Unbiased Truth about What Treatments Work and Why (Get the book.)
