LEARN your teenager's SLEEP pattern!!

It's normal

It's natural for children to stay up late. The onset of puberty changes a child's circadian rhythm. That's the sleep timing system that triggers melatonin – a hormone that makes you sleepy.

As children start to mature into adults, their bodies start secreting melatonin later in the evening, so they don't feel tired and want to stay up later.

Their "sleep pressure rate"– the rate at which sleepiness builds up over the day – also slows down.
