Understanding the Unwanted Biochemistry of Stress Responses

Chapter 1: The Necessity of Stress for Growth
A certain level of stress is essential for us to accomplish tasks. Humans are inherently active beings; we sometimes require a motivational push to break free from our comfort zones. However, excessive stress can be detrimental, leading to feelings of burnout and discomfort.
Stepping beyond our comfort zones is crucial for personal development. While manageable stressors can keep us motivated, an overload—whether stemming from physical, emotional, psychological, or financial challenges—can prove harmful.
The ongoing COVID-19 pandemic has exacerbated these issues, leading to significant financial strain for many due to job losses from lockdowns. This discrepancy in financial stability highlights a broader mental health crisis, as the pandemic has affected not just physical health but emotional well-being as well. Although some stress can be beneficial, chronic stress is decidedly harmful.
Our bodies react to stress in predictable biochemical ways. According to the Mayo Clinic, when we perceive a threat—like a barking dog during a walk—our hypothalamus activates an alarm system that triggers the adrenal glands to release hormones like adrenaline and cortisol.
Adrenaline boosts heart rate and energy levels, while cortisol increases blood sugar levels and enhances the brain's glucose utilization, aiding tissue repair. In essence, stress leads to a heightened release of these hormones.
For thrill-seekers, activities like roller coasters provide an adrenaline rush, resulting in heightened alertness and excitement. However, such experiences can be problematic for parents trying to soothe restless toddlers at bedtime, where an adrenaline surge is the last thing they need.
Excessive excitement leads to the release of stress hormones, and that’s why rides are brief—too much prolonged stimulation could overwhelm thrill-seekers, causing them to lose the joy of the experience.
When stress becomes chronic, our adrenal glands continuously secrete higher levels of adrenaline and cortisol, which can severely disrupt sleep patterns. This lack of quality sleep can further increase stress, creating a vicious cycle. Thus, practices like mindfulness and meditation are gaining traction as effective stress-relief methods.
The Long-Term Effects of Chronic Stress
Constantly elevated adrenaline levels can lead to increased blood pressure, potentially resulting in hypertension. Similarly, high cortisol levels raise blood sugar, which is a primary factor in diabetes. Additionally, cortisol can degrade collagen, accelerating the aging process and leading to issues like wrinkles.

The Emotional and Psychological Consequences of Stress
While the physical effects of stress are significant, we must also consider the emotional and psychological ramifications. Stress can trigger a self-preservation instinct that may be counterproductive in relationships, making individuals more self-centered and less empathetic towards others.
Judy Willis, an educator from California, notes that stress can overactivate the amygdala, the brain region responsible for emotion, impeding the prefrontal cortex's ability to engage in critical thinking. A stressed individual often becomes less altruistic, which is not what the world needs right now.
As the pandemic continues to challenge our mental faculties with a multitude of stresses, learning to connect with others compassionately is crucial. This again requires stepping outside of our comfort zones.
When overwhelmed by stress, emotions, or information overload, it becomes difficult to make sound decisions. However, it’s imperative to cultivate empathy and assist others in finding their own stress relief methods. This understanding goes beyond mere biochemical responses.
