When to give the child the first mobile phone? New study reveals risks parents shouldn't ignore

It's one of the most common questions modern parents face: 'When is the right time to get your child their own smartphone?' While peer pressure ('everyone in the class already has one') is huge, a large new study suggests it's worth taking your time with this decision. In fact, timing can make all the difference to your child's mental and physical health.

The earlier, the greater the risk

Researchers tracked more than 10,500 U.S. teens to see how phone ownership affects their health at age 12. By that time, 64% of the kids already owned a phone (most got one around age 11).

The results showed a disturbing trend: earlier smartphone ownership was associated with significantly worse health outcomes. Compared to children who did not yet have a phone, young smartphone owners faced the following risks:

• 62% higher likelihood of sleep deprivation.
• A 40% higher likelihood of obesity.
• 31% higher likelihood of depression.

What's more, the study revealed a direct correlation: with each year a child got a phone earlier, these risks increased over time. Even children who received a phone "only" between the ages of 12 and 13 were 57% more likely to develop clinical mental health problems than their peers without a phone.

Why are phones harmful? It's not just about the display

It's important to note that the study did not examine what exactly the children were doing on their phones. The problem is probably not the device itself, but what it crowds out of a child's life.

Adolescence is a time of rapid brain development. If a child spends hours of unstructured time on their phone, they are missing out on three key pillars of healthy development:

1. Quality sleep (blue light and notifications disrupt biorhythms).
2. Movement (time on the couch with a cell phone replaces running around outside).
3. Mental rest (downtime, when the brain does nothing and regenerates).

What to take away from this?

Smartphones are not evil in themselves. They can support connection with friends, provide safety and help with learning. But the data clearly shows that timing and boundary setting play a key role.

Based on these findings, researchers recommend delaying the purchase of your own phone until your child is mature enough to handle the responsibilities that come with it. If a child already has a phone, it's essential to set rules that protect their sleep and exercise time.
