Resumen:
This study is part of the major institutional project (Cod.F / B042 SeCTER) that studies the interaction of environmental factors withmelatonin production in the province of Jujuy through differences in solarradiation according to altitude, latitude and time of year in order todetermine the relationship between light, health and well-being of people. Thechronobiology field have shown that light is the main environmental stimulusthat synchronizes circadian rhythms in mammals, determining their physiology.Three aspects related to radiation were studied: photoperiod, heliophania andlight intensity. The last two can be related by means of an intensity value,above which the heliophania registration can be carried out. The aim of thisstudy was the determination of this value. No bibiliographical material existson the subject. Light intensity measurements were made in the Augusto ROMAÍNMeteorological Station of the UNJu (Lat 24º10?S Long 65º11?W 1302 asl), incontrast to the records of heliophania, around the winter solstice, when solarradiation is lower. Statistical analysis of the data was obtained, with averagevalues of 17.01 ± 3.52 kLux as a threshold for the registration of heliophilia,which results in a possible alternative for this last meteorological variable,which makes it a tool for eco-physiology studies. It is also important to studythe cloudiness in the regulation of radiation, due to the convective movementsof air, the presence of water vapor and the condensation and sublimation nuclei
