Top Ten Important Things That Happen to You While You're Sleeping

Sleeping is a daily thing that we usually devote little to no time thinking about. Yet it's one of the most important things in our lives. Humans can't live without sleep. But what happens to us that is so vital, and so interesting, while we sleep, besides the usual "getting rest" idea? What happens to our body, mind, and senses? Today, I'm going to break down all of the top ten most important things that happen to you during sleep. When you jump into your comfy bed, mash your face into the pillow, pull your sheets and comforter up, grab a Teddy bear and catch a few Zs, every single one of these important things happens, usually simultaneously! Enjoy!
The Top Ten
1 Bone and Muscle Improvement

During sleep, particularly the Non-REM stages when you're in deep sleep and not dreaming, your body strengthens and builds your bones and muscles. This relates to the growth hormone I mentioned earlier. I decided to list it separately because the hormone not only builds bones and muscles but also strengthens them.

You know how sometimes you pull a muscle or injure it, and people tell you to get some sleep and it will be better in the morning? That's because of this improvement in bone and muscle. Another thing that happens during this stage is the strengthening of your metabolism.

2 Improvement of Resistance to Health Problems

Have you ever wondered why some people get diabetes, heart problems, obesity, or even all three, while others don't? It's partly random or because of the health choices of the person in question. However, another big factor is good sleep. Getting enough sleep strengthens all of your organs, your immune system, your nervous system, and all your other systems.

But what else does this help, other than the basic functions of these systems, organs, or muscles? It actually improves your resistance to various health problems. While sleep won't improve every health issue, and it may not prevent you from getting an illness, it will help you fight off many health problems. Lack of sleep can induce cancer, heart problems, diabetes, and even obesity, which you might think is caused only by food choices, but it's partly due to insufficient sleep.

3 Physical Growth

Sleeping is essential for the growth of both children and adults, even more so than the veggies and other foods your parents always ask you to eat. During the day, gravity pulls you down, and most people end up about half an inch shorter by the end of the day. While sleeping, you stretch out again, repeating this cycle.

During deep sleep, the body releases a type of growth hormone for kids and young adults, which helps us grow. Additionally, sleep increases the production of proteins, which are necessary to repair body damage and support cell growth.

4 Improvement of Memory Function

One of the most important things that happens during sleep is the improvement of memory function. This means your brain prepares to help you remember the events of the next day. Although sleep also processes the previous day's events, it enables you to retain information for the next day.

When you wake up, it may be easier to answer questions because your brain has helped boost your memory. A personal example is with speeches: practicing late at night can be difficult, but if you practice immediately after waking up, you might remember everything much better.

5 Strengthening of the Immune System

Your immune system helps you fight off sicknesses through a complex network of defenses. Sleep strengthens these defenses, replaces older white blood cells, and revitalizes the immune system. Without adequate sleep, you are more susceptible to illnesses, may get sicker than usual, and take longer to recover.

It's impressive how well the body does this. When you're sick, getting extra rest and a good night's sleep helps you fully recover. We're halfway through the list, and it's amazing that there are still more important functions that sleep supports. Let's continue!

6 Improvement of Ability to Think Clearly

You may have noticed that people often make poor decisions when sleep-deprived. You might do silly things at sleepovers or when you've been up all night working because you haven't had enough sleep.

During sleep, the nervous system not only improves memory function and processes the day's information but also enhances your ability to think clearly and make better decisions. This is crucial because a quick mind is essential for success in life.

7 Healing and Repairing of the Heart and Blood Vessels

Much like with the healing and repairing of human tissue and bones, your body heals and repairs the heart and blood vessels while you sleep, much more so than during the day.

Blood circulation, which is what the circulatory system is all about, is one of the most vital parts of our body. Without it, we wouldn't be able to live, as there would be no circulation.

It's not like your circulatory system would be completely destroyed without this process, but with a lack of sleep, it would deteriorate over time. You'd end up either moving like a sloth (not too bad) or dead.

8 Sorting and Processing of the Day's Information

Without sleep, it's difficult to remember the previous day's events. You might say, "But I've pulled all-nighters before and remembered everything clearly!" That's probably because you slept a few hours afterward.

I remember pulling all-nighters, but I don't remember much of the following day, likely acting like a zombie. Your brain sorts and processes everything that happened during the day. Sometimes, dreams are related to the previous day's events because your body is going through this process. It's very essential.

9 Repairing and Regenerating of Tissues

As you fall into deeper stages of sleep, you become harder to wake and less likely to dream. During this time, your muscles experience a significant increase in blood flow, bringing oxygen and nutrients that help repair and regenerate muscle tissues.

Without this process, working out would be much more difficult, and your muscles would be more tender the next day. Accidental bumps would hurt more than usual.

10 Improvement of Mentality and Emotional State

The last item on our list could arguably be considered the first, depending on your perspective. I placed it here because I wanted to highlight the other important benefits first. For the most part, the more sleep you get, the happier you are, though this varies by person.

Sleep also improves your mentality. Some problems that seemed overwhelming at night appear less daunting in the morning, thanks to sleep. Your soccer coach might always tell you to improve your mentality. One way to do that is by getting more sleep.
