[Relations between health and natural and artificial environment].

On June 2007 WHO issued their first report on impacts of environmental conditions on human health, "Country profiles of the environmental burden of disease". Data relevant to Italy indicate that health diseases caused by environment are 14%. Further papers demonstrated that, in highly technologically developed countries the air available in non industrial buildings (schools, offices, houses, etc.) is more polluted then the air outside and, adding to this that these are the places where population lives up to 90% of the time, this data highlight the importance and extension of the issue. This study recognize, thanks to the cross check of data from various international studies, a strong connection existing between health and psycho physic well-being of human being and a salubrious environment, outdoor and indoor; but, also, the existence of a vicious circle where the outdoor environment degradation lead to buildings indoor pollution and non eco-sustainable buildings new erections worsen the outdoor environment. The challenge for the future is to guard natural environment and to achieve buildings suitable for human being needs and demands and in harmony with natural environment.
