Below is an excerpt of an article that recently came to me from Metagenics Institute where I obtain my supplements. It is particularly relevant for us in the TFT world as it is addressing stress, the topic of our upcoming webinar. The studies show the deleterious effects of stress on our systems and that meditation and acupuncture (using the same meridian system as TFT) are beneficial.

What is stress?
An integrated definition of stress states that it is a constellation of events, starting with a stimulus (stressor) that precipitates a reaction in the brain (stress perception) and results in the activation of the physiological fight-or-flight systems in the body (stress response).1
Stress is a fact of life. We all face stressors of some sort in our day-to-day lives; whether psychological, physiological, or physical. We have evolved with stress, and many of us have learned techniques to manage various stressors, so it makes sense to explore the biological ways in which stress impacts our health.
Research has shown that varying degrees and durations of stress affect each of us differently, and short-term stress (lasting from minutes to a few hours) may actually benefit our immune health; in contrast, weeks, months, or years of stress can be detrimental to our health.2
Many of us are familiar with the “fight-or-flight” response—you may envision an emergency situation like being chased by a lion or needing to react quickly to another dangerous situation. You may even feel your heart racing just thinking about such a scenario. This is the effect of the sympathetic nervous system: stimulus (lion) plus reaction in brain (stress perception), creating a fight-or-flight response in your body (stress response).
In a perceived threatening scenario, where the sympathetic nervous system response is stimulated, norepinephrine and epinephrine potentiate increased arousal, alertness, focus, and core temperature. At the same time, pain thresholds, cardiovascular output, respiratory rate, and blood flow to the brain and skeletal muscles also increase.5
Interestingly, a review of the science suggests that acute stress activates the immune system. Immune activation may be critical for responding to the immediate demands of a stressful situation, especially if the situation results in wounding or infection.
While short-term stress can be an immune stimulator, the same is not true of long-term physiological stress.1 Long-term stress suppresses, or dysregulates, innate and adaptive immune responses.
Just as we all have differing genetic and biochemical composition, we also have varying responses to stressors. There are significant individual differences in stress perception, processing, appraisal, and coping.6 Sometimes there may be a crossover between the mind and body, as in the fight-or-flight response. The stimulus may be stressful mentally and require physical action.
But what about psychological stress that poses no pressing physical danger? Perhaps a stressful work project requiring a few long days and nights? Or the droning on of work, relationship, or other emotional woes? There are many lifestyle factors that may come into play when individuals experience long-standing mental stress. Financial and social support factors have been studied, as well as nutritional intake, sleep quality, and lifestyle decisions (exercise frequency, alcohol consumption, drug use, etc.).5 All of these factors play indirect roles in stress-related immunosuppression; however, many direct effects on immunity have also been demonstrated.5-7
Lifestyle approaches for stress management
While the side effects of stress are far-reaching, (shown in detail in the full article) there are some lifestyle-related activities that can help quell the effects of life’s worries. One method, supported by considerable evidence, is the practice of mindfulness and meditation. Meditation represents a mental training framework for cultivating the state of mindful awareness in daily life.
Regular aerobic exercise, acupuncture, breathing exercises, and progressive muscular relaxation also help individuals to manage stress.27
More studies are needed to explore the physiological benefits of mindfulness and other stress-management techniques, but there is hope for finding a preferred tactic to support all personality types and stressors.
