A Brief Definition Of Health

Health, as defined by the World Health Organization, is ‘a state of full physical, emotional and social well being and not just the absence of sickness and disease’. Over the years, a variety of definitions have also been used for that purpose. According to some, health is having the ability to live and enjoy life free from disease, while other think that health is having a normal and adequate number of physical possessions and being in good psychological and social relationships. Health is important because it determines the course of one’s life and future and also ensures that the material world in which we live remains alive and well. It also contributes significantly towards economic well being and assists in achieving optimum levels of education, employment and leisure.

Another significant factor is environmental factors. These include the physical environment such as the space available to an individual and the air pollution (such as exposure to visible and ultraviolet radiation) in the environment. The determinants of health promotion and disease prevention all play a role in the quality of life.
