Physiological Thresholds

Meaning

These are the critical limits or points of intensity for various internal and external stimuli that, once crossed, trigger a significant and measurable change in the body’s homeostatic mechanisms or functional state. In endocrinology, this often refers to the level of stress, nutrient deficiency, or toxin exposure that pushes the HPA axis or thyroid function beyond its adaptive capacity into a state of dysregulation. Understanding these thresholds is key to preventative health.
