Digital devices disrupts students' sleep cycles, mental health: Australian educators

Using digital devices at night is affecting the sleeping habits of children and damaging their mental health, Australian educators warned.

Liz Bobos, co-president of the Australian Capital Territory (ACT) Principals Association, said that the trend is causing children to act like ‘device vampires’ with disrupted sleep cycles that see them sleep through much of the school day, reported.

Bobos said, "We tuck our children into bed, we read them a story, we say goodnight and we assume that eyes are shut — but there's no guarantee that happens.”

She said that schools had reported an increase in referrals to psychologists but many youth mental health programs did not treat children younger than 12.

Sarah Blunden, director of the Australian Centre for Education in Sleep, said that the blue light emitted by mobile devices delays the release of melatonin, the hormone that regulates sleep, disrupting the body's circadian rhythms, which regulate sleep cycles.

She said, "And because our circadian clock does have a distance to run, because we go to sleep later, we are alert later.

"If you have a disrupted circadian clock, one that is delayed, but also one that is different day to day, you are more likely to have an emotional lability, that is, a much more volatile emotional state.

“You're more likely to be depressed or have waves of depression or anxiety."

Bobos said that schools and parents needed to coordinate to ensure children were using technology appropriately.

“Schools have a huge role to play in teaching children ... about creating balance in their life

"There are apps that parents can put on their own phone that don't restrict children from accessing technology, but allow parents to know what apps their children are accessing, so parents can have a conversation with their kids.

“There's a real opportunity for parents to educate children there."
