Sommario/riassunto |
|
Light is not an inert physical entity. Omnipresent in Nature, it exerts an essential action on living beings, from the smallest to the most complex, including the humans. All living beings depend on the light for their development and life conservation. According to the spectral composition, the effects of light can be beneficial or harmful. Light regulates confined or systemic biological processes and may be used as a therapeutic tool. Light pollution may cause harmful effects in plants and animals, disturbing the stability of ecosystems. All these aspects are treated in Light, Life and Health, in a scientific, historical and sociocultural approach. Within international context, the work that Portuguese produced to study and disseminate those subjects is exposed and a reference is made to the way the phototherapies have been disseminated and established in Portugal. |
