Health is a condition of mental, physical, and social well being where infirmity and illness are absent. It has been said that a life full of health is worth a thousand lives. There are many myths and truths associated with the concept of health. It is the desire of humans to be healthy that has motivated the medical science to create a host of medicines and treatments that are meant to ensure the natural growth of the body. One could also compare it with the saying that an ounce of prevention is worth a pound of cure.
The concepts of public health care interventions are interrelated. Public health advices are aimed at creating awareness on prevention, early detection, and treatment of various diseases and their complications. On the other hand, health care interventions are medical treatments designed to treat a disease or disorder as soon as it is detected. Common examples of such treatments are heart disease, diabetes, and childhood obesity. The objective of health care interventions is to reduce the risks of death and disability caused by these diseases.
The relationship between the public and private sectors has increased the role of environmental health professionals. The interventions of environmental health professionals aim at enhancing the overall quality of life through environmental policies that are designed to minimize the risks of exposure to harmful substances. These professionals are responsible for the identification of the risks to the environment and the creation of protective environments. They also play a major role in the identification of the consequences of these exposures and the design of preventive measures. They advocate for policies that will reduce pollution, fuel emissions, and their effects while improving energy efficiency, environmental cleanliness and reliability and community development.
