Emergency care (life - threatening injuries
or illnesses) The Pet Fund works only on non-basic, non-urgent care, such as cancer treatment, heart

A number of mechanisms may mediate the association between short sleep and overall
or mental well - being, including fatigue
or sleepiness during the day38 and the involvement of metabolic and
endocrine functions.39 The mechanisms linking long sleep and physical well - being are less clear, possibilities are reverse causation, as longer sleep may be an early symptom of undiagnosed
disease, 10
or increased sleep fragmentation.40, 41 However, associations were robust to adjustment for presence of a limiting long - term
illness.
