Air, water, climate, soil, natural vegetation and landforms are all environmental factors. By definition, environmental factors affect daily life and play a key role in generating health differences in geographical areas. Environmental factors include temperature, food, contaminants, population density, sound, light, and parasites. The diversity of environmental stresses that have been shown to cause increased asymmetry is probably not exclusive; many other types of stress could produce similar effects.
An environmental factor, an ecological factor or an ecological factor is any factor, abiotic or biotic, that influences living organisms. Abiotic factors include ambient temperature, the amount of sunlight, and the pH of the soil water in which an organism lives. Biotic factors would include the availability of food organisms and the presence of biological specificity, competitors, predators and parasites. Environmental factors, including nutrition and metallic elements, are implicated in the pathophysiology of Alzheimer's disease (AD).
Living in socioeconomically disadvantaged neighborhoods (as an indicator of a variety of environmental exposures) has been linked to higher rates of injury in both adults and children (Cubbin et al. To be sure, occupational therapists and physical therapists have long appreciated the need for an accurate description of the environmental impact, since many of their interventions depend on it. Social environments can also function through effects on drug use, which also has consequences for violence and mental health-related outcomes. Traditionally, these economic, social, urban or rural, transportation and other policies affecting the environment were not considered relevant to health policy, but are now attracting more attention because decision makers are beginning to recognize their health implications (Cole and Fielding, 200).
Environmental factors that affect physical activity (mainly through its effect on active lifestyles, such as walking) and access to healthy foods (rather than high-calorie foods) may help explain the differences in obesity and related conditions between the United States and other countries of High income countries. As noted in chapter 5, certain forms of drug use (which are often linked to other social and environmental characteristics) also appear to be more prevalent in the United States than in other high-income countries. Environmental factors affect trends in foodborne diseases directly through ambient temperature or indirectly by influencing human activity. Although the development of an organism is presumed to have a strong genetic component, the body's initial environment has a lasting influence.
While studies on residential segregation do not directly assess environmental factors, insofar as segregation is related to differences in exposure to environmental factors, countries with greater segregation may also experience greater spatial inequalities in the distribution of environment factors that lead to greater inequalities in health and possible consequences for the general state of health. However, some of the best evidence of the influence of these environmental factors on the development of hypertension comes from randomized controlled trials that test strategies for the prevention and treatment of hypertension. Environments that discourage physical activity can also limit social interactions, with potential implications for violence and drug use. In conclusion, it can be seen how socio-economic factors of any level play a role in the consequences of human actions on the environment.
