ONYCHOPHAGIA & ANXIETY
If ANXIETY has an underlying fluid dynamic component involving C.L.A.S.S. (see ANXIETY ACTIVATOR) - then NAIL-BITING is a logical reaction. For example, if lymphatic flow becomes blocked or disrupted (this may be as early as birth, in the case of cranial vessel malformation/trauma during labour), the accumulation of pressure around the thoracic cavity would result in heaviness of the chest, slightly laboured/elevated breathing rate, and a typical stress response AND/OR there could be stagnant lymphatic/CSF fluid bathing the amygdala (fear & anxiety center of brain) and pineal region, eliciting an anxious constitution. Subconsciously, the body understands the problem, and so, to improve lymphatic flow in an attempt to relieve anxiety, an individual nail-bites which increases saliva/nasal/lymphatic fluid flow around the oral cavity and lymphatic/blow flow to the tips of the fingers… more specifically, by biting off the nail - the lymphatic system is activated to transport lipid and protein molecules (i.e. keratin) to regrow the severed nail. The same phenomena is likely happening with hair sucking/pulling as keratin is also the primary building block for hair follicles.
