ENVIRONMENT AND HUMAN HEALTH

      ENVIRONMENT 

                         AND 

                     HUMAN HEALTH

What is Environment?

• The term environment has been derived from a French word “Environia” means to surround.
• It refers to both Abiotic (physical or non-living) and Biotic (living) environment.
• The word environment means surroundings, in which organisms live. 
• Environment and the organisms are two organized and complex component of nature.

 What is Health?

 Generally three types of definition of health seem to be possible and are     used 

• The first is that health is the absence of any disease or impairment. 
• The second is that health is a state that allows the individual to adequately cope with all demands of daily life (implying also the absence of disease and impairment). 
• The third definition states that health is a state of balance, an equilibrium that an individual has established within himself and between himself and his social and physical environment.
  

  According to the World Health Organization, Health is "a state of complete  physical, mental and social well-being and not merely the absence of   disease  and infirmity".

  What is Environmental Health?

 The environment can directly and indirectly impact on our health and         wellbeing. Environmental health examines the interaction between the   environment and our health. 

 Definitions:

-  Environmental health refers to aspects of human health (including quality of life) that are determined by physical, chemical, biological, social and psychosocial factors in the environment.

-  Environment broadly includes everything external to ourselves, including the physical, natural, social and behavioral environments. 

 Why is the Environment important for health?

 We need safe, healthy and supportive environments for good health. The   environment in which we live is a major determinant of our health and   wellbeing. We depend on the environment for energy and the materials   needed to sustain life, such as:

• clean air
• safe drinking water
• nutritious food
• safe places to live.

Many aspects of our environment – both built and natural environment – can impact on our health. It’s important that we interpret health issues in the wider context of our environment and where we live.

-  Clean air, stable climate, adequate water, sanitation and hygiene, safe use of chemicals, protection from radiation, healthy and safe workplaces, sound agricultural practices, health-supportive cities and built environments, and a preserved nature are all prerequisites for good health.

-  In order to effectively control factors that may affect health, the requirements that must be met in order to create a healthy environment must be determined.
