Media Use, Sleep and School Work
Sleep is very important to how our bodies function and how
well our brain works. Length of sleep is important and so is the quality of
sleep, that is sleep which is not interrupted by nightmares and waking up during
the night. When you don’t get enough
sleep the brain is affected by not being able to plan and organize activities
or pay attention. This will affect how
well you perform at school. Several studies have shown a link between media use
and poor sleep.
What are the issues?

25 minutes per night of sleep can change school performance.

the Internet leads to an increase in alertness which also might prevent you
from falling asleep easily.
