Light is the main environmental stimulus involved in thesynchronization of biological rhythms in mammals. The light/darkness cyclesperceived by the retina synchronize the neural activity of the suprachiasmaticnuclei, which in turn synchronize the rhythmic production and secretion ofmelatonin from the pineal gland that acts as a neuroendocrine transducer,acting on the health and well-being of people. Jujuy is divided into fourregions: yungas, valleys, quebrada and puna, with a variety of ecosystems, dueto the seasonal variation of the photoperiod, could affect well-being inpeople. The aim of this work was to study the interaction of environmentalfactors with the well- being of people based on differences in photoperiodaccording to region and time of the year (seasonal). In differentrepresentative localities light intensity and photoperiod were measured, andseasonal curves of light were drawn. WHOQOL-BREF were carried out on localpeople to determine their well-being according to the seasons. Differences wereobtained in the ANOVA (n = 20) at α = 0.10 for the variable Physical Healthbetween the Summer-Winter seasons, but not for the variables PsychologicalHealth, Social Relations and Environment. Increasing the size of the samplecould show statistically significant differences. The trend shows that thevalues of all the studied variables decrease towards the winter solstice, andincrease towards the summer solstice, a trend that agrees with the expectedchronobiological models. The results help to deepen the understanding of thedirect biological influences of optical radiation on human populations
