People always mention and talk about environmental health. But what is it actually?
Environmental health
It addresses all the physical, chemical, and biological factors external to a person, and all the related factors impacting behaviours. It encompasses the assessment and control of those environmental factors that can potentially affect health. It is targeted towards preventing disease and creating health-supportive environments.
However, this definition excludes behaviour not related to environment, as well as behaviour related to the social and cultural environment, and genetics.
The following are some of the environment related health problems that needs careful tacking through incorporation of various cross-cutting efforts which quite often goes beyond the influence of ministry of health:
- Living conditions with poor housing and overcrowding, inadequate sanitary facilities, and challenging communicable and vector-borne diseases
- Unhealthy lifestyles and nutrition transition that needs massive behavior change campaigns
- Growing urbanization, unhealthy work environment, and air pollution
- Complexities with food safety and security, food habits and healthy diet
- Climate change and its adverse impacts with extreme climatic behaviors, and need for preparedness to its mitigation and adaptation.
“Providing support to countries in moving to universal coverage with effective public health interventions”
This is designed to include clusters such as communicable and non-communicable disease prevention and control; sexual and reproductive health; infant, child, adolescent and maternal health and the health of older persons; environment-related health problems, and effective response in terms of crisis; and research.
The following are some of the environmental hazards that have caused numerous medical and health problems to the community at risk and susceptible to it:
Indoor air pollution
Exposure to indoor air pollution from solid fuels has been linked to many diseases, in particular pneumonia among children and chronic respiratory diseases among adults.
Outdoor air pollution
Air pollution continues to pose a significant threat to health worldwide. Many countries around the world do not have regulations on air pollution.
Chemical safety
Children's environmental health
Child survival and development hinge on basic needs to support life; among these, a safe, healthy and clean environment is fundamental.
Electromagnetic fields
Electric and magnetic fields are part of the spectrum of electromagnetic radiation which extends from static electric and magnetic fields, through radiofrequency and infrared radiation, to X-rays.
Environmental health in Emergencies
Death and disease burden from emergencies, disasters and disease outbreaks associated with environmental risk factors can be significantly reduced by effective prevention, preparedness and response capacities.
Global environmental change
Large-scale and global environmental hazards to human health include climate change, ozone depletion, loss of biodiversity and much more.
The aim of the Radiation and Environmental Health Program is to look for solutions to protect human health from ionizing radiation hazards by raising people's awareness of the potential health risks
Occupational Health
Workplace fatalities, injuries and illnesses remain at unacceptably high levels and involve an enormous and unnecessary health burden, suffering, and economic loss.
Ultraviolet radiation
Ultraviolet (UV) rays are a part of sunlight that is an invisible form of radiation. UV rays can penetrate and change the structure of skin cells. There are three types of UV rays: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). UVA is the most abundant source of solar radiation at the earth's surface and penetrates beyond the top layer of human skin. Small amounts of UV are essential for the production of vitamin D in people, yet overexposure may result in acute and chronic health effects on the skin, eye and immune system.
Water, sanitation and health
Water pollution is a major problem in the global context. It has been suggested that it is the leading worldwide cause of deaths and diseases. As aspects of water, sanitation and hygiene oppose a very high health burden, where interventions could make a major difference and where the present state of knowledge is poor. However, many countries are challenged to provide these basic necessities to their populations, leaving people at risk for water, sanitation, and hygiene (WASH)-related diseases.
