Aspects of health

Physical health

A strong indicator of the health of localized population is their height|weight, which generally increases with improved nutrition and health care. This is also influenced by the standard of living and quality of life. Genetics also plays a major role in people's height. The study of human growth, its regulators, and implications is known as Auxology.


Mental health

Mental health refers to an individual's emotional and psychological well-being. Merriam-Webster defines mental health as "A state of emotional and psychological well-being in which an individual is able to use his or her cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life."

According to the World Health Organization, there is no single "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined. In general, most experts agree that "mental health" and "mental illness" are not opposites. In other words, the absence of a recognized mental disorder is not necessarily an indicator of sound mental health.

One way to think about mental health is by looking at how effectively and successfully a person functions. Feeling capable and competent; being able to handle normal levels of stress, maintain satisfying relationships, and lead an independent life; and being able to "bounce back," or recover from difficult situations, are all signs of mental health.

A combination of physical, emotional, social and most importantly mental well-being is necessary to achieve overall health.

Determinants of health

A major environmental factor is water quality, especially for the health of infants and children in developing countries.[4]

Studies show that in developed countries, the lack of neighborhood recreational space that includes the natural environment leads to lower levels of neighborhood satisfaction and higher levels of obesity; therefore, lower overall well being.[5] Therefore, the positive psychological benefits of natural space in urban neighborhoods should be taken into account in public policy and land use.
