Excessive screen time linked to early puberty

Blue light could influence physical growth & development

Even as children are increasingly getting exposed to screens from a young age, a new study in rats showed that long-term exposure to blue light, emitting from smartphones or tablets, may lead to early puberty.

The findings linked the early risk of puberty with accelerated bone growth and bone age caused because of exposure to blue light.

The research, presented at the 62nd Annual European Society for Paediatric Endocrinology Meeting in Liverpool, is the first to explore the link between bone growth and pubertal development.
