Episode 9: 我为什么需要睡觉？Why do we need sleep?
This episode drops Tuesday, October 27.
Description
In this episode, we explore a question every kid protests at bedtime: 我们为什么需要睡觉？Why do we need sleep?
Together, we discover that sleep isn't just "doing nothing" — it's actually when your brain gets busy behind the scenes, sorting through everything you learned that day and helping your body grow stronger while you rest. Your brain even switches on its own cleaning system that can only run while you’re asleep.
我们会发现，睡觉并不是"什么都不做"——其实，睡觉的时候，大脑正在悄悄地工作，整理你这一天学到的东西，还帮助身体变得更强壮。你的大脑甚至还会打开一套自己的清洁系统，而且只有在你睡着的时候才能运作。
Along the way, we practice five key vocabulary words in context, with sentences your child can use right away.
大脑 dà nǎo (brain)
记忆 jì yì (memory)
修复 xiū fù (to repair)
肌肉 jī ròu (muscles)
清洁 qīng jié (to clean)
Perfect for little listeners aged 5–8. 适合5到8岁的小听众。
Discussion
Keep the conversation going after the episode. Here are a few questions to ask your little one.
How do you feel when you wake up after a really good night’s sleep? What about when you didn’t sleep enough?
睡得很好以后醒来，你觉得怎么样？没睡够的时候呢？What’s one new thing you learned today that your brain might “save” tonight while you sleep?
你今天学到了什么新东西？今天晚上睡觉的时候，你的大脑可能会把它存起来哦！When you’re sick, you feel extra sleepy. Why do you think your body wants more sleep then?
生病的时候，你会特别想睡觉。你觉得为什么那个时候身体想要多睡一点呢？
