To understand the screen time parenting debate,Lets go to some basics.
We start with White and grey matter .
White matter according to google acts as the high-speed, structural communication network (nerve fibers) that connects different brain regions, allowing for rapid signal transmission. It supports cognitive growth, motor development, and language skills by forming white matter tracts, heavily relying on myelin development to increase transmission
Gray matter is a major component of the central nervous system, comprising neuronal cell bodies, dendrites, and glial cells, primarily responsible for processing information, sensory perception, memory, emotions, and voluntary muscle control. It makes up about 40% of the brain, largely located in the outer cortex, while white matter (60%) handles communication.
Now excess screen exposure reduces the white a matter volumes and this directly affects language and motor development.
A White matter, known as myelin, functions as insulation and conductor for brain signals. Damage to this area disrupts neural connectivity causing brain impairment and so is linked to delayed development in children.
How then is Grey Mater affected ?
Excessive exposure to screen can lead to reduced cortical thickness, especially in areas responsible for critical thinking, empathy, and decision-making.(Striatum)
High screen usage correlates with structural changes in the brain's cortex in some cases the brain shrinks ,and reduces in size.
Lastly Lower grey matter has been linked to potential cognitive decline and symptoms similar to early dementia in extreme.
All these Billions cells rapidly develope every min inside the brain.Look at your kids brain like a Large City under construction and b needs good foundation.picture it this way 'You are the builder from conception to to 18 years.They will do the finishing from age 18 -24 yrs .
Understanding the weight of these things may be helpful so that we dont choose good English over long term Habits that boosts Brain health.
