When we were a hunter/gatherer society and living on the plains, we were also a food source for other predators. We were not the strongest or biggest animal on the plain so we adapted survival mechanisms. Stress is one of those survival mechanisms designed to keep us alert. When we scanned the terrain thousands of years ago, our attention was directed to what was out of place. We picked up on what was moving in a still setting or what was still in a dynamic setting. We looked for things to eat or things that could eat us. Have you noticed that when things

are running smoothly that your stress level is almost zero? You remain vigilant but, as soon as something out of the ordinary occurs, you become more attentive to the change? If the change increases to become a threat, then your stress level increases commensurately. If the threat is immediate, we also have the ability to react immediately. If we had to think of this process before reacting, we would be some other animal’s dinner. Stress bypasses the normal thinking- reasoning network so we can react to a threat. You don’t have to go through the thinking-reasoning process to know to pull your hand away from a hot stove top. This is also why we react so quickly to an electrical shock — it’s immediate. There is no time to go through the normal protocol of traveling through the nervous system to the brain to decipher what is happening, decode the information and then encode it so the proper signal is transmitted to our proper muscle to pull away from the threat. Adrenaline is pumped into our body to react instantly. Job stress can be defi ned as an

individual’s reactions to characteristics of the work environment that seem emotionally and physically threatening — it just has to have the appearance of a threat, not necessarily be a real threat.


AND THE STRESSFUL There are good and bad sides to stress. The good thing is that it keeps us safe. The bad thing is the same thing that keeps us safe — it is reactionary. Excessive stress leads to distress that is mentally and physically damaging as well as cumulative. Stress builds when we don’t decompress during our time off after dealing with stress at a certain level of degree and/or duration. My wife can attest to that. Research has discovered that

accumulated stress in many individuals had a signifi cant negative eff ect on physical health — stress causes an increase in notated high blood pressure, stroke and heart attack. With regard to cognitive function, important negatives include noted degradation of long- and short-term memory, situational awareness, ability to communicate, risk assessment and vestibular function (balance), and the potential for a profound psychological impact. These include depression, high divorce rate, a marked lower quality of life and higher incident of suicide.

Systemic stress inhibits long-term potentiation. This is an important biological model of synaptic plasticity which is the ability of the brain to function properly and acts like an insulator between two electrodes. It causes hippocampal atrophy (associated with dementia), impairs learning, facilitates long- term depression, contributes to brain aging, causes many generalized behavioral changes, is implicated in many neuropsychiatric disorders and depresses the immune system. It also modulates neurotrophic factors, especially brain-derived neurotrophic factor that is an important feature in the production of proteins that regenerate nerve cells.
