Abstract

Umjetna rasvjeta je u zadnjem stoljeću postala sastavni dio života bez kojeg moderno društvo ne može funkcionirati. Evolucijskim mehanizmima sunčeva svjetlost je određivala cirkadijalne ritmove ljudskog tijela. Plava svjetlost, prisutna za vrijeme dana, aktivira retinohipotalamički put i suprahijazmatsku jezgru. Ona pak inhibira lučenje melatonina iz pinealne žlijezde. U nedostatku plave svjetlosti (za vrijeme mraka), dolazi do stvaranja melatonina i njegovih brojnih načina djelovanja u ljudskom organizmu. Melatonin, uz djelovanje na cirkadijalni ritam, djeluje pozitivno na imunološki sustav, protuupalno, tumor supresorski i kao antioksidans. Djeluje kao hipnotik, sedativ i anksiolitik. Umjetna rasvjeta, osobito fluorescentne žarulje i sve više korištene LED žarulje odašilju diskontinuiran spektar pretežito kratkih valnih duljina (plava svjetlost). Uz UV zračenje, plava svjetlost djeluje negativno na ljudski organizam. Disregulacija proizvodnje melatonina dovodi u djelatnika koji rade pod umjetnom rasvjetom do pojave malignih bolesti (tumor dojke, prostate, karcinom endometrija), reproduktivnih problema i poremećenog obrasca sna. Potrebno je uzeti u obzir rad pod umjetnom rasvjetom kao rizik za zdravlje i posvetiti se tome problemu u javnom zdravstvu.

Abstract (english)

In the last century artificial lights have become an integral part of life and without them modern society cannot function. Sunlight has determined the circadian rhythms of the human body by evolutionary mechanisms. Blue light, present throughout the day, activates the retinohipothalamic tract and suprachiasmatic nucleus. The nucleus inhibits the excretion of melatonin from the pineal gland. Melatonin is produced in the absence of light, and therefore has effects on the human organism. Melatonin affects circadian rhythm, positively affects the immune system, has anti-inflammatory effects, is tumor suppressor and is an antioxidant. It is known as a hypnotic, sedative and anxiolytic. Artificial lights, particularly fluorescent lamps and increasingly used LED diodes emit a spectrum of predominantly short wavelengths (blue light). Along with UV radiation, blue light has a negative effect on the human body. Disruption of melatonin production in workers who work under artificial lights leads to an increase in occurance of malignant diseases (breast tumors, prostate cancer, endometrial cancer), reproductive problems and disturbed sleep patterns. Artificial lights as a health risk must be considered and addressed as problem in public health.
