At the end of this session the participants should be able to conceptualize: 1. health in its physical, mental, social and spiritual context;. 1. apply the concept of environmental hazards on their day to day life 2. understand the influence of environment on human health. INTRODUCTION TO. Relationship between Environment & health- authorSTREAM Presentation.
Role of Environment in Health 4 Physical environment includes air, water, soil, housing etc.
Biological environment includes plants, animals, insects, bacteria etc. Social environment includes customs, culture, habits, occupation etc.
Environment and disease 5 Many of the diseases in man are caused by adverse environmental factors like Water pollution, air pollution, soil pollution, poor housing, insect vectors, animal reservoirs etc.Public Health Environmental Powerpoint Templates
Due to industrialization and urbanization environmental pollution has increased, resulting in increased morbidity Environmental sanitation: Environmental sanitation 6 Environmental sanitation is not merely sanitary disposal of excreta It means — clean home, clean farmclean business, clean neighborhood and clean community The purpose of environmental health is to create and maintain conditions that will promote health and prevent disease Objectives: The circumstances, objects, or conditions by which one is surrounded or The complex of climatic, edaphic soil-basedand biotic factors that act upon an organism or an ecologic community Public health definition of "the environment": Public health definition of "the environment" All that which is external to the individual host.

Health is a state of complete physical, mental and social well being and not merely an absence of disease or infirmity WHO What is a disease What is a disease Trouble or a condition of the living animal or plant body or one of its parts that impairs the performance of a vital function Why study environmental health: WHO definition of environmental health Environmental health comprises those aspects of human health, including quality of life, that are determined by physical, biological, social, and psychosocial factors in the environment.
It also refers to the theory and practice of assessing, correcting, controlling, and preventing those factors in the environment that can potentially affect adversely the health of present and future generations Facets of environmental health: Facets of environmental health Environmental epidemiology Associations between exposure to environmental agents and subsequent development of disease Environmental toxicology Causal mechanisms between exposure and subsequent development of disease Environmental engineering Factors that govern and reduce exposure Facets of environmental health: People with health issues like asthma, compromised immune systems are more sensitive.
Environmental And Health |authorSTREAM
Many diseases have genetic as well as environmental factors. Much research has proven that breast cancer can be caused by either emvironmental or genetic factors…and if caught early can be curable. Thalidomide, a drug that currently shows promise for treatment of Alzheimer's, AIDS, and some cancers, caused thousands of severe birth defects when it was used as an anti-nauseal in the s and 60s.
With chemical hazards, scientists determine toxicity, human exposure, frequency of exposure, concentration of exposure, etc.
- Environmental Health What is the relationship between the health of the planet and our own health?
The probability that a hazard will cause harm Risk assessment: The process of measuring risk Takes into account: The type of hazard How frequently humans will be exposed to it How sensitive people are to it 6 Biological and Social Health Hazards in the Environment Three quarters of infectious disease deaths are caused by five types of diseases: InAIDS killed about 2 million people worldwide— almost equal to the entire population of Arkansas.
Monitors health events worldwide and coordinates international responses to emerging diseases Centers for Disease Control and Prevention CDC: Examples of social hazards include smoking, being exposed to secondhand smoke, living near an old toxic waste site, working with harmful chemicals, and eating fatty foods.
A pollutant is something released into the environment that has some harmful impact on people and other organisms. Chemical hazards are not necessarily pollutants, and pollutants are not necessarily chemical hazards.
Cancer-causing chemicals Chemical mutagens: Chemicals that cause genetic mutations Teratogens: Chemicals that harm embryos and fetuses Neurotoxins: Chemicals that affect the nervous system Endocrine disruptors: Chemicals that interfere with the endocrine system Allergens: Chemicals that over-activate the immune system Dust mite protein is a common allergen.
Natural sources, such as volcanic eruptions, or human sources, such as pesticides In the ground: Pesticide use, improper disposal of electronics, etc. Chemical runoff from land or direct drainage of toxic substances into water 17 Physical Health Hazards Although we cannot prevent most natural disasters, there are steps that scientists, engineers, governments, and citizens can take to resist damage and deal with the aftermath.
Earth Quakes, Volcanos, Storms, and Avalanches are just some examples of natural disasters that can create environmental hazards.
