The term lifestyle is rather a diffuse concept often used to denote “the way people live”, reflecting a whole range of social values, attitudes and activities. It is composed of cultural and behavioural patterns and lifelong personal habits (e.g. smoking, alcoholism) that have developed through processes of socialization, life styles are learnt through social interaction with parents, friends, peer groups and siblings and through mass media and school.
It may be noted that not all lifestyle factors are harmful. There are many that can actually promote health. E.g. Adequate nutrition, enough sleep, sufficient physical activity etc. In short, the achievement of optimum health demands adoption of healthy lifestyles. Health is both a consequence of an individual’s lifestyle and a factor in determining it.
