Self-care  In health care, self-care is any necessary human regulatory function which is under individual control, deliberate and self-initiated. Some place self-care on a continuum with health care providers at the opposite end to self-care while others see a more complex relationship. In modern medicine, preventive medicine aligns most closely with self-care. A lack of adherence to medical advice or the onset of a mental disorder can make self-care difficult. Self-care is seen as a partial solution to the global rise in health care costs placed on governments. The notion that self-care is a fundamental pillar of health and social care means it is an essential component of a modern health care system governed by regulations and statutes. Self-care is considered a primary form of care for patients with chronic conditions who make many day-to-day decisions or self-manage their illness. Self-management is critical and self-management education complements traditional patient education in primary care to support patients to live the best possible quality of life with their chronic condition. Self-care is learned, purposeful and continuous. In philosophy, self-care refers to the care and cultivation of self in a comprehensive sense, focusing in particular on the soul and the knowledge of self. There are a number of self-care requisites applicable to all humans across all ages and necessary to fundamental human needs. For example, as humans we need to intake sufficient air, water and food; care also needs to be taken with the process of elimination and excrement. There must be a balance between rest and activity as well as between solitude and social activities. The prevention and avoidance of human hazards and participation in social groups are also requisites. Maturity requires the autonomous performance of self-care duties. According to the Middle-Range Theory of Self-Care of Chronic Illness, self-care is defined as the process of maintaining health through health promoting practices and managing illness and is performed in both healthy and ill states. Self-care is composed by three dimensions: self-care maintenance, self-care monitoring and self-care management. Factors affecting self-care are: experience and skill, motivation, cultural beliefs and values, confidence, habits, functional and cognitive abilities, support from others, and access to care. Stemming from the theoretical framework many instruments were developed in order to allow clinicians and researchers to measure the concept of self-care in different situations in patients and their caregivers:   Self-care maintenance refers to those behaviors performed to improve well-being, preserve health, or to maintain physical and emotional stability.
