Technology, Sleep, and Learning: What Parents Need to Know

In today’s world, technology is everywhere—and our children are using it more than ever. From phones and tablets to video games and TV, screens are a big part of daily life. But how much is too much? And how does screen time affect children’s sleep, learning, and brain function?

Learning and Focus

Technology can impact the brain in various ways, both positive and negative. It can influence attention, memory, sleep, and even brain structure. While it can enhance certain cognitive functions, overuse can lead to issues like reduced focus, memory problems, and changes in brain chemistry.

The Impact on Sleep

Research shows that too much screen time—especially before bed—can make it harder for children to fall asleep. Screens give off blue light, which tricks the brain into thinking it’s still daytime. This stops the body from making enough melatonin, the hormone that helps us sleep.

Tired brains don’t learn as well. When children don’t get enough sleep, it’s harder for them to concentrate, solve problems, and remember what they’ve learned. Less screen time, especially before school and bedtime, helps children stay focused and ready to learn.

Online Safety and Age-Appropriate App Use

As children become more confident with technology, it's important to guide them in using it safely and responsibly. Many popular apps like TikTok, Snapchat, and Instagram have age restrictions (usually 13+) to help protect young users. These platforms are not designed for younger children and can expose them to inappropriate content, online bullying, and risks to privacy. Cyberbullying can be just as harmful as bullying in person—it can affect a child’s self-esteem, mental health, and ability to learn at school. We encourage parents to talk with their children about respectful online behaviour, set clear boundaries, and check app settings regularly. Let’s work together to keep our children safe and kind online.

What Can PARENTS AND SCHOOLS Do?

Here are some simple ways to support healthy tech use at home:

• Create a tech-free bedtime routine. Turn off screens at least 1 hour before bed.
• Keep bedrooms screen-free. Charge devices outside the room.
• Encourage outdoor play and reading. These activities support brain development and reduce stress.
• Model healthy habits. Children learn from what we do, not just what we say. Adults need to lead by example.

Technology is a great tool when used wisely—but balance is the key. By supporting healthy screen habits, we help our children sleep better, learn better, and feel better every day.
