““Typical sympathoadrenal response to both acute and chronic high altitude exposure. During initial exposure, epinephrine levels increase dramatically as a direct result of hypoxia on stimulating adrenal medullary activity. As oxygen content improves over time with acclimatization, this stimulus is lessened and epinephrine levels return toward sea level values. Sympathetic nerve activity, however, increases steadily over time at altitude as indicated by both arterial and urinary norepinephrine levels. There is a transient increase in cortisol levels with initial exposure to altitude””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Acute altitude spikes adrenaline; chronic exposure raises norepinephrine and cortisol then normalizes adrenaline
In simple terms: High altitude triggers stress hormones, then adjusts over time
