Psychophysiological Aspects of Stress
Stress is not just a psychological phenomenon; it has profound effects on our physiology. The psychophysiological aspects of stress refer to the intricate interplay between our psychological experiences and the resulting physiological changes in the body. When we perceive a threat or challenge (a stressor), a complex cascade of events unfolds involving the nervous, endocrine, and immune systems.
Here are some key psychophysiological aspects of stress:
-
Activation of the Sympathetic-Adrenal-Medullary (SAM) Axis: This is the body’s immediate “fight-or-flight” response. The hypothalamus, upon perceiving stress, signals the sympathetic nervous system, leading to the release of catecholamines (epinephrine and norepinephrine) from the adrenal medulla. This results in:
- Increased heart rate and blood pressure
- Rapid breathing
- Increased alertness and focus
- Muscle tension
