Alarming MRI research on preschoolers (ages 3-5): Only 2hrs of daily screen engagement is linked to loss of white matter in the brain.
Professor Mike Nagel at the University of the Sunshine Coast: “White matter is myelin — it insulates axons like plastic on a wire. Deficits in myelin early in life mean deficits in neural connectivity.”
Increased exposure leads to more significant reductions, particularly in regions linked to language skills and reading ability.
Nagel's initial response, both as an expert and a dad:
“Wow…I was not anticipating seeing anything like that. It hadn’t occurred to me that something as little as 2 hours a day was having such a profound effect.”
Fellow parents, does this make you reconsider screen rules for little ones, or do you feel the concerns are exaggerated?
