Researchers from Gazi University and Ankara City Hospital in Turkey exposed 18 immature female rats to a spectrum of light predominantly emitted by our LED screens for relatively short or long periods each day.

The longer the exposure, the earlier the onset, the onset of puberty, says lead author Aylin Kilinç Uğurlu. The research was presented at the 60th Annual European Society for Paediatric Endocrinology Meeting in Rome.Read Long Article
