homeostasis derives from the combination of the Greek words "homeo" or constant, and "stasis" or stable, and is defined as remaining stable or staying the same [3]. It relates to physiological mechanisms needed to sustain life by responding and adapting to changing environmental conditions, while investing energy to maintain order [4]. Thus, it refers to the organism's internal self-regulation process that plays a major role in maintaining a constantly balanced, harmonic and steady-state condition [5].The concept of homeostasis is largely discussed in the literature within the context of biological and physiological processes. However, throughout the life cycle humans need to modify their behavior to adapt to daily activities [6]. Studies that associate the concept of homeostasis to human behavior focus mainly on socio-emotional and psychological behavioural adaptations or adjustments in response to stressful events, e.g., [3,7]. Yet, literature examining implementation of this concept to day-to-day activities in relation to persons' academic, social and leisure and work pursuits is absent. Moreover, no theoretical framework has comprehensively captured the conceptualization of how individuals create or develop daily functional homeostasis as manifested in the control, harmony and balance of their daily life activities and routines.
Conceptual Foundations and Purpose of the Daily Function HomeostasisThe Daily Function Homeostasis (Day-Fun-Home) philosophical framework was founded on the literature and extensive research that focus on human daily functioning throughout the life span. Three main resources lead to the fremawork's core concepts and stucture. The first is the Abstract Homeostasis refers to the organism's internal self-regulation process that plays a major role in maintaining a balanced, harmonic and steady-state condition. The aim of this paper is to present a comprehensive conceptual framework for developing daily functional homeostasis, which illustrates the control, harmony and balance of daily life activities and routines. This framework provides a systematic procedure for revealing the person's true desired self (who I am) by providing reflective key points. These points include environmental and personal factors, life events, past experiences and key points in the context of disease or disability. Dimensions of a person's activities and participation, such as what, where, when, why and how they are performed, can provide new insights stimulating daily functional changes. The analysis facilitated by the framework considers the person's life goals and identifies gaps or conflicts that challenge their achievement. Moreover, utilizing a person's strengths to develop adaptive changes may circumvent existing barriers and lead to improved sense of control, self-fulfillment, life satisfaction, health and well-being.
