Why Do We Yawn and Rub Our Eyes Before Bed? Understanding Sleep: The Basics of How Sleep Works
Ever noticed how animals and even your little baby brother seem to just shut down and drift off to dreamland effortlessly? It’s almost like there’s a magical sleep button they press! But what actually happens when we sleep and why is it so important? Today, we’re going to dive into Understanding Sleep: The Basics of How Sleep Works in a way that’s easy and fun. So let’s begin our adventure into the world of sleep!
What is Sleep?
In simple terms, sleep is a state our body and mind enter every day which allows us to rest and recover. Think of your body like a smartphone. Throughout the day, you play games, send messages, and watch videos, which drains your phone’s battery. Sleep is like plugging your phone in at night – it helps recharge your battery so you’re ready to go the next day!
How Does Sleep Work?
Our brain controls our sleep cycle through signals that make us feel awake or sleepy. This cycle is split in two main types: REM (Rapid Eye Movement) Sleep and non-REM Sleep, each playing different roles in keeping us healthy and smart!
Non-REM Sleep
This type of sleep has three stages and makes up about 75% of our sleeping pattern:
-
Stage 1:
- Just after falling asleep.
- It’s a light sleep where you can be easily woken up.
- Imagine it like dozing in class when the lesson seems, well, a bit boring.
-
Stage 2:
- You are in a deeper sleep.
- Your body starts to slow down, your temperature drops a bit, and your heart beats slower.
- It’s like when you’re hiding under a cozy blanket, noticing less and less of what’s going on around you.
-
Stage 3:
- This is the deepest sleep stage.
- It’s very hard to wake someone up from this stage.
- Your body is repairing muscles and tissues, stimulating growth and development, boosting immune function, and building up energy for the next day.
REM Sleep
- Occurs roughly after 90 minutes into your sleep.
- This is the stage where you have vivid dreams.
- Your brain is super active, almost like when you’re awake!
- REM sleep helps process emotions and memories, which is why it’s so important.
Why Is Good Sleep Important?
Imagine trying to do your homework, play sports, or even hang out with friends after not sleeping well. Everything would feel much harder, right? Good sleep lets your brain sort all the information you’ve gathered during the day, making learning much easier. It also keeps your body healthy by helping heal your heart and blood vessels, and even helps in growing taller!
How Much Sleep Do We Need?
Just like everyone has a favorite ice cream flavor, different people need different amounts of sleep. However, here are some general recommendations:
- Children (6-13 years): 9-11 hours
- Teenagers (14-17 years): 8-10 hours
- Adults (18 years and older): 7-9 hours

What happens if I don’t sleep enough?
- Not sleeping enough can make you feel grumpy, tired, and it’s harder to concentrate or do well in school.

Can you “catch up” on lost sleep?
- Sleeping more on the weekends can help a bit, but it’s better to try and get consistent sleep every night.

Why do I remember some dreams and not others?
- During REM sleep, your brain is almost as active as when you’re awake, so you remember dreams if you wake up during this stage.
