Environmental risk and risk perception management in public health

When evaluating environmental risk and its perception, psychosocial and psychosomatic factors may be of fundamental importance for public health programming and the promotion of quality of life. This is the case in particular where knowledge of the true health consequences of environmental exposure to given risk factors are incomplete or its action is within the range of values where we do not anticipate the measurable biological effect. This applies not only in the case of the indoor environment related complaints but also to that of non-ionizing electromagnetic radiation and electroionic microclimate, among many others. A serious consequence found in the syndrome of mass hysteria is the fact that due to differently motivated information and disinformation, part of the population can suffer from psychosomatic symptoms and deterioration quality of life for those affected.
