Sleep helps the brain — Psychology, 4–6 years

Sleep is not just stopping for the night. While we sleep, the brain sorts some of the day’s experiences and the body gets ready for tomorrow.

What sleep does

Sleep gives the body a quiet time to rest, but the brain is still working in a different way. It can sort some memories, strengthen things we practised and help us feel ready to think again.

Why sleep matters

People noticed that after a short night they often feel grumpy, clumsy or foggy, even when they want to play. Sleep helps solve this problem by giving the brain and body time to recover and organise their work.

A day with enough sleep

Mila hears a new song on Monday and tries its clapping pattern twice. On Tuesday, after sleeping, she remembers more of the pattern and can clap along with less help. Sleep did not practise for her, but it helped her brain keep part of Monday’s learning.

Sleep is not wasted time

A child may think that staying awake gives more time for games and learning, so sleep seems like time taken away. That idea is reasonable, but too little sleep can make attention, memory and movement harder the next day.

Sleep in everyday life

Sleep matters before a day at nursery, a visit or a game that needs careful listening. A calm bedtime routine can make it easier to settle down, although every child’s sleep needs and family routines are not exactly the same.
