The need for sleep is so basic that a second system -- called the homeostatic sleep drive -- monitors how much the body has had and sends out a powerful drowsiness signal if it needs more.
We do, in part, and this effect is caused by the so-called homeostatic drive, one of the two main factors influencing sleepiness and alertness.
Walter Cannon, going back to Claude Bernard, emphasized that the health and even the very existence of the body depends on what are called homeostatic processes ... that is, the apparent equilibrium of life is an active equilibrium, in which each deviation from the norm brings on a reaction in the opposite direction, which is of the nature of what we call negative feedback
Going from the lowest level to the top, the first level of needs, survival and physiological, are things like breathing, food, water, sleep, homeostatic which is the ability of an organism to maintain an internal equilibrium, and excursion.
The word "homeostatic," adopted in cybernetics for feedback systems in general, originated in 1920s human physiology to name self-regulation of body fluids, digestion, and metabolism. [
A living thing, a self, is a homeostatic system, a system constantly being disrupted by exterior forces and internal requirements for refueling and maintenance, constantly seeking to stabilise itself, to return to equilibrium, but also relishing the instability -- because that tension is life.
This sort of balance of affects in the aim of functioning as a social human being is pretty much the definition of mental health, whereas pathologies are pretty much defined by how that homeostatic system goes wrong, in vicious cycles of bad affect-logic that render one socially dysfunctional.
Most psychological pathologies appear quite comprehensible as distortions of that homeostatic system into vicious cycles, destabilising feedback loops that render an individual dysfunctional because the system has become self-disrupting rather than self-correcting.
Arguably, this dichotomy is a deeply unhealthy attitude, a neurosis situating self entirely in the superego and demonising the libido as a base and bestial “animal nature” that must be mastered, rather than the natural self-correcting impulses of a homeostatic system designed to maintain a dynamic equilibrium.
Thus, although leptin appears to have little effect on the homeostatic system across a wide range of levels, when leptin levels drop below a putative “threshold” (as in weight loss), it triggers a powerful anabolic response resulting in a reduction in energy expenditure and an increase in orexegenic signals.
