Digital health – level 3

19-12-2022 15:00

Some Americans check their smartphones 96 times a day, or once every 10 minutes. Screen time additionally creates digital eye strain and can damage eye parts and the ability to focus.

Children are getting more screen time due to the pandemic. Children’s screen time went from 6 hours to 13 hours a day. Some studies show that too much screen time leads to lower language and thinking test scores and the thinning of the brain’s cortex, where we do critical thinking and reasoning.

The screens also impact their sleep, and sleep is important to the brain’s development and memory. Blue light from screens lowers a brain chemical called melatonin; melatonin helps you go to sleep. The screens then keep children more awake at night.

Difficult words: digital eye strain (when your eyes get tired from looking at screens too much), focus (to see clearly with both of your eyes), cortex (the front of the brain).
