💡 Sleep Myth: Blue light is the main reason children can't sleep.

For years, we've been told that blue light from phones and tablets is one of the biggest causes of poor sleep. But the latest research suggests the picture is more nuanced.

A review by Professor Michael Gradisar found that while screen use can affect sleep, blue light itself may have a much smaller effect than we once thought.

So what does have the biggest impact?

✨ Staying up later because content is engaging.

✨ Exciting or emotional content that keeps the brain alert.

✨ Using screens because a child is already finding it difficult to fall asleep.

This doesn't mean light isn't important ...far from it.

Our body clock responds to light throughout the WHOLE day.

☀️ Bright morning daylight helps set your child's body clock.

🌤️ Plenty of natural light during the day supports healthy sleep.

🌙 Lower light levels in the evening help prepare the brain for sleep.

So rather than focusing only on blue light, think about your child's overall light exposure and bedtime routine.

Small changes can make a big difference:

✔️ Get outside in the morning whenever possible.
✔️ Encourage plenty of natural daylight during the day.
✔️ Dim the lights in the hour before bed.
✔️ Keep bedtime calm and consistent.

Healthy sleep isn't just about avoiding screens; it's about giving your child's body clock the right light at the right time.

Have you noticed your child sleeps better after a day spent outdoors?
I'd love to hear your experience. ⬇️
