Acute Stress
I have always been extremely fascinated with the intricate adaptation and regulation of the human body to acute stress. The concern here is not eliminating the source of stress but understanding the physiology behind the stress and learning how to the effectively cope under stress, this is called Stress Management. Throughout this series various stress-related topics will be explored and as a result a more competent approach to stress management.
The Silent Killer
This molecule is called Cortisol. Released in the body from the Zona Fasiculata in the Adrenal Cortex in response to stress (public speaking, fear, worry, anger, etc.)
Adrenal Gland Histology
When Cortisol is secreted in the body it tends to degrade leukocytes. As a result it can lead to leukopenia and thus a depression of the immune system. This is the reason why some tend to experience illness after enduring significant periods of stress; finals week, wedding planning, work seasons, etc.
The interesting part about Cortisol is that we actually do need it in order to provide adequate fuel for our brain.
Cortisol is mainly involved in Gluconeogenesis which is important when the body is running on low Glycogen stores when Glucose (brain-food) is in demand. Gluconeogenesis involves the conversion of amino acids (from protein, like Actin/Myosin which make up skeletal muscles) into glucose. As a result, we may observe see muscle atrophy when we do not allow our bodies to rest after exercise routines (stress).
Because we cannot eliminate the adrenal hormone entirely from the complex endocrine system, we must compensate for the effects when it’s circulating through our bodies. I tend to engage in both passive and active relaxation.
Passive Relaxation: Praying, reading, listening/playing music, washing dishes, folding laundry, drawing, etc.
Active Relaxation: running, swimming, team sports, etc. (Added bonus, endorphins!)
