Effects Of Stress On The Nervous System
- 1. Effects OF Stress on the Nervous system By: Nicole Tallman
- 2. Components of the CNS Sympathetic nervous system Responsible for expending energy Initiates the stress response Parasympathetic nervous system Responsible for conserving energy Induces the relaxation response Long term chronic stress can lead to serious health problems
- 3. Fight or flight Stress causes the adrenal gland, atop the kidney, to release the hormone adrenaline, but many other hormones, including a related one, noradrenaline, stream into the blood as well. Adrenaline and noradrenaline are also secreted from nerve cells, or neurons, where the compounds act as neurotransmitters, chemical messengers that enable one neuron to communicate with others.
- 4. Continued A high concentration of noradrenaline in the blood, which occurs in people with tumors of the adrenal gland, can fatally damage the muscle of the heart. Cortisol is also released from the adrenal glands. Excess cortisol in the blood interferes with mood enhancing neurotransmitters called serotonin. Disturbances in serotonin levels can be a factor in causing clinical depression and anxiety disorders as well as being linked to insomnia, obesity and increased sensitivity to pain.
- 5. Adrenal exhaustion Stress can cause an increase in ACTH production which creates more demand on the adrenal gland to produce more Cortisol Hypothalamus keeps sending the message of “Stress” and can’t shut off the production of Cortisol, ultimately “exhausting” the Adrenal Gland.
- 6. Conditions associated with Adrenal Exhaustion Increased infections Fatigue Headaches Cancer Hypoglycemia PMS And many others
- 7. NEUROLOGICAL TENSION Tension that builds up, layer upon layer, within the Central Nervous System, distorting the brain’s ability to perceive and respond to life. It is generated from poor posture, repetitive motions, muscle weakness and imbalance, poor sleep, poor diet, Adrenal Exhaustion, couch potato lifestyle, and anything else that is not optimal to our overall health.
- 8. WAYS TO MANAGE STRESS Exercise Calming techniques like yoga, tai chi, meditation Better eating habits, staying away from pop, caffeine Change your response to stress Get at least 7 hours of sleep per day

Notes de l'éditeur
- In the long term these hormones cause blood clotting to increase and blood cholesterol levels to elevate increasing the risk of many diseases such as heart disease, stroke and angina. Stress hormones also weaken the immune system in the long term leaving us more vulnerable to infections. Increases in blood pressure are another long term effect of these stress hormones increasing the risk of stroke, heart attack and kidney disease. Chronically tensed muscles brought about by the stress response can lead to pain in the neck and back for example. Excess cortisol in the blood interferes with mood enhancing neurotransmitters called serotonin. Disturbances in serotonin levels can be a factor in causing clinical depression and anxiety disorders as well as being linked to insomnia, obesity and increased sensitivity to pain. Certain brain neurotransmitters have antidepressant and anti-anxiety effects and regulate appetite. Research indicates the balance of neurotransmitters affect everything from sleeping, waking, love, stress, anger, optimism, pessimism, risk taking behavior, aggression, drug abuse, alcohol abuse, violence, anxiety, appetite etc.Neurotransmitters are very powerful hormones that are secreted by the brain and nervous system and have a powerful effect on our psychological and physical health. Fortunately, the body has a compensating system which switches off the stress response and releases chemicals that reduce blood clotting, reduce blood fats, lower blood pressure and heart and breathing rates.These chemicals such as serotonin, adrenaline, noradrenaline, endorphins, dopamine,etc., have a very powerful influence on our mood and to a degree on the way we think. Depression and anxiety, Pre Menstrual Syndrome, social phobia, anxiety, aggression, obsessive compulsive disorder, post traumatic stress disorder, violence, gambling, overeating, excess sex, drug abuse, have all been partly linked to low levels of neurotransmitters among other factors
