of artwork (Kelly McGonigal). Not only does stress motivate you mentally, it also motivates you physically. A group of researchers at Princeton University proved that exercise such as running rearranges the brain so that there is a reduced stress response as well as less interference with anxiety and the brain’s normal functions (Morgan Kelly 1). Particularly, this research study found that running produced a significant increase in the number of new neurons in the hippocampus of mice that ran…

Depending on the context, the reaction can vary from avoiding a physical or psychological treat, or engaging in a life-saving fight. According to Cannon (1929) some of the advantages of panic are: an increase of sugar in the blood which is used for metabolism; effects of fatigue are reversed by epinephrine; the re-route of blood circulation by the nervous system to support maximal…

ideation or attempts. Aviation members are not protected within the confidential programs through CGSUPRT; if a member chooses to seek help for stress he/she must divulge what is supposed to remain confidential in accordance with ref. (b), to the flight surgeon in accordance to ref (a). Aviation medical policy found in Ref. (b) must be revised to allow the uninhibited use of CGSUPRT resources without fear of repercussions. 2. The policy found in ref (a) which reads, “Aviation personnel are…

Often times, when we hear the term, “survival of the fittest,” we associate it with animals and how they have taken advantage of their evolutionary timeline. Even though the term might imply that the animal most “fit” would be more likely to survive, it is not in the sense of how physically fit they are. According to Charles Darwin, “It is not the strongest of the species that survives, nor the most intelligent, but the one most responsive to change.” But in the world of science fiction, would…

What is Fear? Topic: Fear Thesis statement: Fear is something that many of people try to avoid; they don’t realize that it is a feeling that that activates our natural survival instincts and according to Walter Bradford Cannon, activates fight or flight mechanisms helping us to survive. Everyone’s life is changed by fear weather they know it or not. According to Psychology Today, there are five different types of fear “Extinction—the fear of death, Mutilation—the fear of losing any part of our…

axon’s often experience growth in the presence of estrogen. This is due to distinct differences in what chemicals testosterone and estrogen activate during fight or flight. Testosterone activates primarily Adrenaline which promotes fight or flight while estrogen activates Oxytocin (Taylor et al. 2000). This reaction tends to encourage a response called tend & befriend in which a person reaches out to another in times of stress, promoting the growth of…

limbic system and “takes control” of homeostatic mechanisms. The hemostatic mechanisms regulates blood pressure, body temperature, heart rate and are also involved with the “fight or flight” response. This substance decreases anxiety by limiting the anxiety symptoms which were shown to originate by the “fight or flight” response. While this research was primarily about the Kava supplement’s effect in the human body, it also proved to reduce…

General Adaptation Syndrome The body has its way of responding to external reactions. It can be through adapting or preparing to respond to a situation effectively. General adaption syndrome refers to a collection of these responses. In the event of a dangerous situation, the body is altered by the side effects of stress; therefore, responding to restore balance. Han Selye was the first scientist to discover these side effects and identified them as stress (Cooper, 2017). He further…

time. “Stress can be defined as our response to events that disrupt, or threaten to disrupt, our physical or psychological functioning” (Lazarus and Folkman, 1948; Taylor, 1999). Stress is either physical or mental and generally caused by external stimuli called “stressor”. It can also be defined as events or situations in our environment that causes stress (Robert A. Baron). Interesting feature of stress is that the different or variety of reaction or response of people to a same or…
