Stress: Effects of Stress
By: Vanessa Munera
When people talk about stress, what exactly is it? Stress is the body’s reaction to any change that requires an adjustment or response. With stress the body reacts to these changes with emotional, physical, and mental responses. Stress could either be presented as a positive or negative outcome in people’s daily lives.
According to Bernstein “Stress can occur in a variety of forms” (2016). Some stress can result in short events such as an argument with a loved one. Furthermore, other stress can manifest due to reoccurring conditions; for example, a demanding job, financial problems, and/ or long term illness. When reoccurring conditions cause stress to be both intense and sustained over a long period of time, it can be considered as “chronic” or “toxic” stress”. While all stress triggers physiological reactions, chronic stress is indeed to be considered a problematic issue that creates significant harm to the brain and the functioning of the body. In fact, “stress continues to be a major American health issue”.
If you have experienced a stressful event, a certain area of the brain called the amygdala, responsible for emotional processing, sends a distress signal to the hypothalamus. The hypothalamus functions as a command center in the brain, communicating with the rest of the body through the nervous system so that person has the energy to fight or flee”. The sympathetic nervous system is responsible for the “fight or flight” response because it provides the body with a burst of energy so that it can respond to perceived dangers. Some of the affects from the “fight or flight” response are increased heart rate, deeper intake of oxygen, heightened senses, and the rush of adrenaline – also known as epinephrine, a hormone secreted by the adrenal gland. Finally a hormone known as cortisol is released to help restore the energy that was lost during the response. When stress is no longer present, your cortisol levels to go back to normal as if nothing happened. In addition cortisol helps regulate metabolism and immune responses.
When dealing with chronic stress, cortisol levels are at a constant high, which eventually causes health problems. Although cortisol is a natural and healthy hormone in the body, constant high levels of it can be bad for your brain. High levels of this hormone can wear down the brain’s ability to function properly. As stated in the article, “it can disrupt synapse regulation, resulting in the loss of sociability and the avoidance of interactions with others” (Bernstein, 2016). In addition, chronic stress can kill brain cells and cause the brain to shrink in size. It has a shrinking effect on the prefrontal cortex which is responsible for memory and learning. Besides chronic stress having effects on the brain, it causes effects to the human body. This type of stress can increase the risk of heart disease, high blood pressure and diabetes. Furthermore, it can affect other systems in the body and cause them to stop working properly. This includes digestive, excretory and reproductive structures and exacerbates already existing illness. Fighting and managing chronic stress can be difficult; however it is not too late to learn how to manage it. Toxic stress can negatively affect the brain but the brain and body can recover from these effects.
