Tolerance allows the body to work in normal (healthy) values under different environmental conditions. It is associated with the principle of homeostasis.
<h3>Homeostasis and tolerance</h3>
Homeostasis refers to the state of internal equilibrium in which the body can function normally.
In homeostasis, the body is able to tolerate a broad range of conditions (e.g., different temperatures).
In healthy conditions, the body is able to perform all metabolic functions (e.g., reproduction, growth, repair, etc).
