Addiction dangers of too much screen time early in life
“Early screen viewing is likely to lead to long periods of viewing for the rest of your life," says Sigman. "The way you view screens when you are young forms the habits you pick up for ever after it seems.”
An early taste for entertainment screen media can lead to changes in the brain that stay with you for life – a life that may be shorter as a result.
Like other addictions screen time creates significant changes in brain chemistry – most notably, in the release of dopamine. This neurotransmitter – also known as the pleasure chemical – is central to addictions from sugar to cocaine.
