HEALTH 
How fitness is perceived is based upon on how fitness is described. In the preamble to its constitution, the World Health Organization (WHO) defines fitness as a “u.s. of the united states of entire physical, intellectual, and social properly being and now no longer in truth the absence of infection and infirmity” (Hood & Leddy, 2002). Such a definition of fitness does now no longer permit for any version in tiers of properly being or contamination. On the possibility hand, the idea of a fitness–contamination continuum al-lows for a extra variety in describing someone`s fitness status. By viewing fitness and contamination on a continuum, it`s some distance viable to con-sider someone as having neither entire fitness nor entire contamination. Instead, someone`s u.s. of the united states of fitness is ever-converting and has the capability to variety from excessive-degree properly being to extraordinarily lousy fitness and coming near to shut to death. 
The obstacles of the WHO definition of fitness are smooth on the subject of chronic contamination and incapacity. A chronically unwell character can`t meet the requirements of fitness as established thru way of technique of the WHO definition. 
WELLNESS 
Wellness has been described as being same to fitness. Cook-fair (1996) indicated that properly being “consists of a aware and de-launch technique to a complicated u.s. of the united states of physical, psychological, and religious fitness and is a dynamic, fluctuating u.s. of the united states of being”. Leddy and Pepper (1998) contended that properly being is in-dicated thru way of technique of the capability of the character to carry out to the amazing of his or her capability, the capability to alter and adapt to severa situations, a advocated feeling of properly being, and a experience that “the whole thing is together” and harmonious. With this in mind, it turns into evi-dent that the reason of fitness care companies is to sell exceptional modifications which might be directed withinside the route of fitness and properly being. The truth that the experience of properly being has a subjective aspect emphasizes the significance of spotting and responding to affected individual character-ity and variety in fitness care and nursing.

Health is visible as because of a way of life this is orientated withinside the route of properly being.
