Children spend more time using screens than ever — for schoolwork, gaming, watching videos, chatting with friends and simply relaxing. For parents, this can raise an important question: could all that screen time affect a child’s posture?
The answer is more nuanced than simply saying that screens cause “bad posture”. Screen use often involves prolonged sitting and staying in one position, particularly when a child looks down at a phone or tablet. Over time, these habits may contribute to neck, shoulder or upper-back discomfort in some children.
The good news is that parents do not need to eliminate screens completely. The bigger goal is to create healthier habits around movement, sitting, screen position and regular breaks.
When children use a tablet, phone or laptop, they may naturally move their head forwards or downwards to see the screen.
You may notice your child:
None of these positions is necessarily harmful for a short period. The concern is more about duration and repetition.
The body is designed to move through different positions. Spending a long time in one posture can increase muscular fatigue and discomfort, particularly when combined with insufficient physical activity.
Research in children and adolescents has found an association between sedentary behaviour and neck pain, although the evidence does not establish that screen time alone causes neck pain.
This distinction is important: there is no single “perfect posture” that children need to maintain all day.
Instead, children benefit from regularly changing position and moving.
Not necessarily.
Posture is influenced by many factors, including:
A child who occasionally slouches while watching television is not automatically developing a posture problem.
The greater concern is a pattern of prolonged sitting with very little movement.
This is why Australia’s 24-hour movement guidelines focus on the overall balance of movement, sedentary behaviour and sleep rather than treating screen time as an isolated issue. For children aged 5–17, the guidelines recommend at least 60 minutes of moderate-to-vigorous physical activity each day and breaking up long periods of sitting as often as possible.
For Australian children and teenagers aged 5–17, the Australian Government recommends no more than 2 hours of sedentary recreational screen time per day.
This recommendation does not include screen time required for schoolwork.
That distinction matters.
A child might spend time on a computer completing homework and then spend additional time gaming, watching YouTube or scrolling on a phone. The recreational component is the part covered by the 2-hour recommendation.
The guidelines also recommend breaking up prolonged sitting and getting plenty of physical activity throughout the day.
For younger children, the recommendations are different. Children aged 2–5 years should have no more than 1 hour of sedentary screen time per day, while screen time is not recommended for children under 2.
These are useful targets, but parents should also consider the child’s whole day — including movement, sleep, school, family activities and recreation.
One of the simplest changes is to avoid having children constantly look down at a device.
Where practical:
The aim isn’t to force a rigid posture. It is to reduce prolonged positions where the head and neck are constantly bent down.
Children should not be expected to sit perfectly still for hours.
Encourage them to:
The Australian movement guidelines specifically recommend breaking up long periods of sitting as often as possible.
A short movement break is often more useful than repeatedly telling a child to “sit up straight”.
Good posture is not simply about the position of the spine.
Children need opportunities to run, jump, climb, swim, ride bikes, play sport and participate in active games.
Australian guidelines recommend at least 60 minutes of moderate-to-vigorous physical activity every day, with vigorous activities and muscle- and bone-strengthening activities included on at least three days each week.
Movement builds strength, coordination and physical confidence — all of which contribute to how children use their bodies.
Constantly correcting a child’s posture can sometimes make them overly focused on sitting rigidly.
Instead of:
“Sit up straight!”
try:
“Let’s change position.”
or:
“You’ve been sitting for a while — let’s have a movement break.”
The goal is comfortable, varied movement, not maintaining one position indefinitely.
For schoolwork, look at the child’s overall workstation.
Ideally:
A workstation does not need to be expensive. Small adjustments can make a significant difference to comfort.
Portable devices are particularly easy to use in awkward positions.
Children may use them:
These positions are not automatically problematic. The issue is spending long periods in the same position.
Encourage children to change positions regularly rather than trying to find one “perfect” position.
Screen habits are also connected with sleep.
For children aged 5–13, Australian guidelines recommend 9–11 hours of uninterrupted sleep per night. For teenagers aged 14–17, the recommendation is 8–10 hours. The guidelines also recommend avoiding screen time for one hour before bed and keeping screens out of the bedroom.
Good sleep is an important part of healthy development and should be considered alongside physical activity and sedentary behaviour.
Children notice what adults do.
If parents spend long periods looking down at their own phones, it can be difficult to convince children to take movement breaks.
Try creating household habits such as:
Healthy screen habits work better when they become a family routine rather than a rule that applies only to children.
A child occasionally slouching is usually not a reason for alarm.
However, parents may want to pay more attention if a child regularly complains about:
Persistent or significant symptoms deserve an appropriate health assessment rather than simply being labelled as “bad posture”.
Neck symptoms can have many possible causes, and a healthcare professional can help determine whether further assessment is appropriate.
Not every child with imperfect posture needs treatment.
For a child who is otherwise comfortable and active, simple changes such as increasing movement, adjusting screen use and improving their study environment may be all that is needed.
If a child has persistent pain, restricted movement or other symptoms, however, an assessment may help identify factors contributing to the problem.
At Angel Chiropractic in Annerley, children’s care can include assessment of musculoskeletal concerns, posture and movement, along with advice for parents.
Any treatment should be tailored to the individual child, and parents should seek appropriate medical assessment when symptoms are concerning or outside the scope of routine musculoskeletal care.
Seek prompt medical attention if a child’s neck or back symptoms occur after significant trauma or are accompanied by concerning symptoms such as:
These symptoms should not simply be attributed to screen use or posture.
It is easy for parents to become focused on whether their child is sitting “straight”.
A healthier way to think about the issue is:
Move often. Change position. Limit prolonged sitting. Use screens sensibly. Get enough sleep. Stay active.
Screen time itself is not necessarily the enemy. Children use technology for education, communication, entertainment and social connection.
The concern is when recreational screen use starts replacing activities that growing bodies need — particularly movement, outdoor play, social interaction and sleep.
For Brisbane families, the Australian Government’s movement guidelines provide a useful framework: children aged 5–17 should aim for at least 60 minutes of moderate-to-vigorous physical activity each day, minimise prolonged sitting, limit recreational sedentary screen time to no more than two hours per day, and get adequate sleep.
If your child is experiencing ongoing neck, back or posture-related discomfort, Angel Chiropractic in Annerley can provide an assessment and discuss whether chiropractic care or another form of professional care may be appropriate.
Tech Neck & Poor Posture: How Desk Work Is Causing Neck, Back & HeadachesProlonged screen use often involves sitting in one position, looking down or leaning towards a device. This may contribute to muscular fatigue or discomfort in some children. Evidence suggests an association between sedentary behaviour and neck pain in children and adolescents, although screen time alone cannot be said to cause posture problems.
For children and young people aged 5–17, Australian Government guidelines recommend no more than 2 hours of sedentary recreational screen time per day. Screen time needed for schoolwork is excluded from this recommendation.
Raise the tablet where practical, avoid prolonged looking down, encourage regular movement breaks and allow your child to change positions regularly. The goal is not perfect posture but varied, comfortable movement.
No. There is no single posture that needs to be maintained continuously. Children benefit from changing positions and moving regularly rather than trying to hold one rigid posture for long periods.
If pain is persistent, worsening, repeatedly returning or interfering with normal activities, it is worth arranging an appropriate health assessment. Symptoms following significant trauma or accompanied by neurological symptoms require prompt medical attention.
A chiropractor can assess musculoskeletal factors such as movement, posture and joint or muscle function. At Angel Chiropractic, children’s care is tailored to the individual child.
