There is a delay in the hormone melatonin, which helps us get to sleep, is released from the brain, so teenagers do not feel sleepy until later, such as 11pm.

Technology and social media have also been to blame for teenagers not getting enough sleep at night as their brains are too overstimulated to go to bed earlier.

Once again this teenager’s brain is overstimulated as he is using technology late at night.

Watching TV late at night can also over stimulate the brain making it harder to go to sleep, according to the Sleep Health Foundation of Australia.

James is feeling the effects from his use of technology late at night.

The use of technology, the delay of melatonin release and the early school start times all could be contributing to James struggling to concentrate on his homework and becoming grumpy.

James eventually falls asleep on his homework. Maybe next time he should avoid technology late at night and start a bed time routine so he doesn’t find it as difficult to wake up in the morning and concentrate at school.
