With
increased use of technology in many teenager's lives, some are spending a large
proportion of their day looking at TV, computer, laptop, mobile phone and
tablet screens. Heavy technology use is linked to fatigue,
stress and depression in young adults (Thomée,
Härenstam, & Hagberg, 2011). Furthermore, high levels of screen-time
combined with physical inactivity
are associated with a range of health issues for young people such as obesity,
metabolic syndrome, and poor mental health (Graham
& Hipp 2014). Although teenage
boys are typically more active than girls (Hallal, Andersen, Bull,
Guthold, Haskell, & Ekelund, 2012),
boys report significantly higher levels of screen-time, making them susceptible
to unhealthy weight gain and poor social and emotional well-being.
Although parents report being worried
about their teenagers screen-based activities, they acknowledge computers and
the internet as valuable learning tools (Turow, 1999). Many education providers such as Christchurch Boys' High School are placing an increased emphasis on
using technology for student learning.
Recommendations for the amount of
discretionary screen time (not homework related screen time) for teenagers
varies. Netsafe
recommend "Good Old Fashioned parenting"
when setting boundaries for technology use:
- Setting boundaries as soon as a child gets their first device means it becomes normal for internet time to be limited in your household and less difficult to enforce later on.
- Parents can also model good behaviour, perhaps agreeing to no devices at the dinner table or after a certain time at night so emails and texts don’t disrupt family time.
- Moderation is key – try to make sure your children have plenty of other activities to balance the time they spend online. As a parent or caregiver you may be faced with anger and tantrums over this
Dr Aric Sigman recently created a report
for Family First New Zealand analysing screen time in New Zealand youth. Sigman describes discretionary screen time as an emerging factor in child and
adolescent health. His report highlights the dangers of too much discretionary
screen time as a health and development issue. "Parents should be
encouraged to monitor and control the time their children spend on hand-held
computer games / media / tablets / smartphones with justification that
discretionary screen time is now officially a health and development issue not
merely a lifestyle / cultural one" (Sigman, 2015). Sigman recommends youth
employ self-awareness and self-discipline and that 12 - 15 year olds do not
exceed 1.5 – 2 hour/day of discretionary screen time and people over 16 years
of age do not exceed 2 hour/day of discretionary screen time.
