(A) Adaptive homeostasis was defined as the transient reversible adjustments of the homeostatic range in response to exposure to signaling molecules or events. Any biological function or measurement oscillate around a mean or median, within a homeostatic range that is considered a “normal” or physiological, upgraded from Reference [131]. (B) Adaptogens and physical exercise adjust the homeostatic range of salivary nitric oxide. Effects of physical exercise and androgens on the nitric oxide level in saliva of athletes regularly trained for 3 and 7 years ¹⁴¹ [Color figure can be viewed at wileyonlinelibrary.com]
