Health

The World Health Assembly defined health as "a state of complete physical, mental and social wellbeing and not merely the absense of disease or infirmity."
The World Health Organisation supplemented this by stating that health is "a resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities."

Physical health

Physical fitness is good bodily health, and is the result of regular exercise, proper diet and nutrition and proper rest for physical recovery. It is also influenced by individual and general standards of living and quality of life.
Studies show that in developed countries, the lack of neighbourhood recreational space that includes the natural environment leads to lower levels of neighbourhood satisfaction and higher levels of obesity and therefore lower overall wellbeing. Personal health partially depends on the cultural, social and environmental structure of one's life.
