Homeostatic feeling is a class of feelings (e.g. thirst, fatigue, pain, desire, malaise, well-being) that inform us about our physiological condition. [1] In his earlier work Antonio Damasio used " primordial feeling " but he now prefers the term "homeostatic feeling" for the class.
When people with fibromyalgia are subjected to intense stimuli, they experience sensory overload in the form of pain. It is theorized that abnormal activity of the left dorsolateral prefrontal cortex and reduced production of or reception to serotonin are partially responsible for the sensation of pain in response to intense stimuli.

Emotional exhaustion is a symptom of burnout, [1] a chronic state of physical and emotional depletion that results from excessive work or personal demands, or continuous stress. [2] It describes a feeling of being emotionally overextended and exhausted by one's work.
Despite its benefits, exercise is a challenge for patients with fibromyalgia, due to the chronic fatigue and pain they experience. [145] They may also feel that those who recommend or deliver exercise interventions do not fully understand the possible negative impact of exercise on fatigue and pain. [ 146 ]
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire ...
Psychogenic polydipsia caused by psychiatric disorders—oftentimes schizophrenia—is frequently accompanied by the sensation of dry mouth. Some conditions with polydipsia as a symptom are non-psychogenic (e.g., early Type 2 diabetes, primary hyperaldosteronism, and zinc deficiency, and some forms of diabetes insipidus).
Type A (essential hypernatremia syndrome) involves an increase of the level in which solvent molecules can pass through cell membranes (osmotic threshold) for vasopressin release and the activation of the feeling of thirst. This is the most characterized sub-type of adipsia, however there is no known cause for Type A adipsia.
Central nervous system fatigue, or central fatigue, is a form of fatigue that is associated with changes in the synaptic concentration of neurotransmitters within the central nervous system (CNS; including the brain and spinal cord) which affects exercise performance and muscle function and cannot be explained by peripheral factors that affect muscle function.
