When I am stressed, I have the tendency to attack the problem immediately and eventually pretend it never existed in the first place. During this, I can also feel my body go through changes like increased heartbeat, trembling, or difficulty breathing.
Firstly, my habit of both pursuing and avoiding the problem can be generalized as a fight or flight response. Nerve impulses from the hypothalamus move to the ANS, which causes the body to act in relation to the stressor. High amounts of glucose and oxygen are brought to the organs which regularly protect us from harm such as the brain (will become alert), skeletal muscles (will mobilize us to flee or fight), and the heart (will pump blood in our body).
The other symptoms of stress that I feel can be described using the resistance reaction. This is a longer lasting response that is majorly initiated by hypothalamic releasing hormones. CRH, GHRH, and TRH are the corticotropin-releasing hormones involved. CRH will stimulate the pituitary to release ACTH, causing our adrenal cortex to release an influx of cortisol. Tissues throughout the body can use the resulting glucose, fatty acids, and amino acids to produce ATP or to repair damaged cells. Tissues throughout the body can have access to the resulting glucose, fatty acids, and amino acids to produce ATP or to repair damaged cells.
