What Is Core Sleep?

Core sleep is the most important part of our nightly rest. It’s like the essential sleep that our bodies really need.

During core sleep, our brains go through deep stages, helping us feel rested and ready for the next day. It’s like the main course in a meal – the most satisfying part.

This type of sleep is crucial for our health and well-being. It’s when our bodies repair and restore, making sure we’re strong and healthy. Think of core sleep as the key ingredient for a good night’s sleep recipe!

Is Core Sleep A Good Thing?

Yes, core sleep is a very good thing! It’s like the superhero of our nightly rest.

When we get enough core sleep, our bodies and minds feel supercharged. It helps us stay healthy, strong, and ready for the adventures of the day.

Washed pillows are also an important factor of getting enough core sleep, because of hygiene and reduced allergens. If you have a memory foam pillow you can find out how to wash it here.

Core sleep is like the secret potion that helps us grow, learn, and be our best selves.

How Long Should You Be In Core Sleep?

You should aim for about 9 to 11 hours of sleep every night when you’re younger. It’s like giving your body and brain the right amount of rest they need to stay healthy and ready for the day.

As you grow older, the amount of core sleep you need might change a bit. For tweens and teens, around 8 to 10 hours is usually good. Even grown-ups need about 7 to 9 hours.

Think of it like charging your phone – if you don’t charge it enough, it won’t work well. Your body is a bit like that too. So, make sure to get the right amount of core sleep to feel your best!


Which Sleep Stages Do We Go Through?

When we sleep, our brains go through different stages. The first stage is like a light nap, where we start feeling drowsy. In the second stage, we go a bit deeper into sleep, and our bodies begin to relax. Then comes the third stage, the deep sleep, where our bodies do important repair work.

After these stages, something interesting happens – REM sleep. During REM, our eyes move quickly, and this is when we have vivid dreams. It’s like a movie in our minds! REM sleep is crucial for our brains, helping us remember things and be ready for the next day.

We go through these stages several times each night, like a sleep adventure that keeps us healthy and ready for new adventures when we wake up.

What Affects The Various Sleep Stages? 

Imagine your sleep as a journey, and each part of it is like a different chapter in a book. Now, what affects how these chapters unfold?

Sometimes, it’s things around you, like how comfy your bed is or if there’s too much noise. Other times, it’s what’s happening inside you. Things like how tired you are or if your brain is busy thinking about fun things or important stuff.

If your bed is not comfortable anymore, maybe it is time to change the mattress. Click here to find out why and what are the side-effects.

So, what you feel and what’s around you both play a big part in making sure each chapter of your sleep story is just right!

Non-REM Sleep: The Quiet Recharge

Picture your sleep like a journey, and Non-REM is the start of this adventure.

In the first stage, it’s like a light nap. If something nudges you, you might wake up easily. Your muscles start to loosen up.

Moving into the second stage, your sleep gets deeper. Your heart slows down, and your body temperature drops a bit. It’s the kind of sleep that makes you feel refreshed.

Then, there’s the third stage, the deep sleep. They call it delta sleep. Here, your body does important stuff like fixing tissues and boosting your immune system.

Non-REM sleep is like a superhero, quietly doing its job. It’s your body’s way of fixing and getting ready for the new day.

So, when you’re in Non-REM sleep, think of it as your body taking a peaceful break, recharging for whatever comes next!

REM Sleep: The Dreamy Adventure

Now, let’s talk about REM sleep – the time when dreams take center stage in your sleep story. REM sleep is also the most important sleep stage.

In this special stage, your brain becomes super active, almost like it’s putting on a nighttime show just for you. It’s when you start dreaming vividly.

REM sleep is super important for our minds because it helps us remember things better. It’s like a brain workout that makes us smarter.

What’s interesting is that your muscles take a break during REM sleep. They become temporarily relaxed, like your body is saying, “Chill out, we’re in dreamland now.”

REM sleep is vital for your mind. It helps with memory and learning, sorting through the events of the day, and managing your emotions.

So, when you’re in REM sleep, it’s like entering a world of imagination where your brain is the star, creating dreams that make your night full of excitement and wonder.

Non-REM vs. REM Sleep

When we sleep, our brains go through different stages. Two important stages are Non-REM (Non-Rapid Eye Movement) and REM (Rapid Eye Movement) sleep.

Non-REM sleep is like the quiet part of the night. It has three stages. In the first stage, you feel drowsy and might wake up easily. The second stage is a bit deeper, and your body starts to relax. The third stage is the deepest, where it’s hard to wake you up.

On the other hand, REM sleep is like the exciting part of the night. Your eyes move quickly in different directions, and this is when dreams mostly happen. Your body becomes almost like a statue – very still.

During the night, we cycle through these stages multiple times. Non-REM helps your body rest and repair, while REM is essential for your mind and dreams. Both are important for a good night’s sleep and feeling refreshed in the morning.
