Why Do We Sleep? What Happens When We Snooze?

So you know why do we need sleep? You have no idea? Most people don't give it much thought. They just know that they need to get their eight hours every night.

Sleep is a vital part of our lives, and yet it remains somewhat of a mystery to us. Scientists are still working to unlock all the secrets of sleep, but we do know some things about why we need it and what happens when we drift off. For starters, it helps us to stay healthy and function at our best. It's also thought to play a role in memory, learning, and mood.

While it can be an overwhelming discovery to learn about the science of why are you sleeping, it is important to know the basics. After all, getting a good night's sleep is essential to our overall health and well-being.

Here's what you need to know about why do we sleep and what happens when we snooze.

The Science of Sleep

Humans spend about one-third of their lives asleep, which means that sleep is pretty darn important. But what exactly happens when we hit the hay?

There are two types of sleep: REM (rapid eye movement) and non-REM. We cycle through both of these phases several times throughout the night.

During non-REM sleep, our breathing and heart rate slow down and our body temperature drops. This is the time when our bodies can heal and repair any damage from the day.

REM sleep is when we dream. Our eyes move rapidly back and forth during this phase, hence the name. Scientists believe that REM sleep helps to boost learning and memory by solidifying new information in our brains.

It's still a bit of a mystery why we need sleep, but scientists have some theories. One is that it helps to clear out any toxins that have built up in our brains during the day. Another is that sleep gives our bodies a chance to recover from the physical and mental stress of the day.

So if you're having trouble catching some Z's, don't hesitate to reach out to a doctor or sleep specialist. They can help you figure out what might be causing your sleeplessness and recommend ways to get your snooze on.

What Happens When We Don't Sleep?

Now that we know a little bit about why sleep is important, let's talk about what happens when we don't get enough of it.

Not getting enough sleep can have some pretty serious consequences. It can lead to weight gain, moodiness, and even depression. It can also affect our immune system, making us more susceptible to illness. And if that wasn't enough, it can also make us less productive and more accident-prone.

In other words, not sleeping is no joke!

What's the Math Behind 8-Hours of Sleep?

Most people know that they need to get eight hours of sleep per night, but have you ever wondered why?

Well, it turns out that eight hours is the magic number for a few reasons. First, it's the amount of time that our bodies need to fully recover from the day. Second, it's the amount of time that we need to keep our immune system functioning properly. And lastly, it's the amount of time that we need to maintain a healthy weight.

Moreover, eight hours is the amount of time that most people need to feel rested and alert during the day. Of course, there are always exceptions to the rule. Some people can get by on less sleep, while others need more than eight hours to feel their best.

But 8 hours is an ample amount of time for your body to feel rested, so it's a good number to aim for if you aren't already.

What to Do to get Sleep?

There are a few things that you can do to make sure that you get enough sleep. First, establish a regular sleep schedule and stick to it as much as possible. This means going to bed and waking up at the same time each day, even on weekends.

Second, create a bedtime routine that will help you wind down for the night. This could include taking a warm bath or reading a book before bed.

And lastly, create a sleep-friendly environment in your bedroom by making sure that it's dark, quiet, and cool. This will help signal to your body that it's time to sleep when you get into bed.

Following these tips should help you get the shut-eye that you need to function at your best.

Factors that Could Affect your REM Sleep

There are a few things that can affect the quality of your REM sleep. 

  • One is stress. If you're feeling stressed, it can be harder to fall asleep and stay asleep throughout the night. This is because stress causes our bodies to produce cortisol, which is a hormone that keeps us awake and alert.
  • Another factor that can affect REM sleep is diet. Eating sugary or fatty foods before bed can cause disruptions in our sleep cycles.
  • And lastly, caffeine and alcohol can also affect REM sleep. Caffeine is a stimulant that can keep us awake, while alcohol is a depressant that can make us feel drowsy.

How to Know if I Have a Sleep Disorder?

Sleep disorder is a condition that prevents a person from getting enough sleep. There are many different types of sleep disorders, including insomnia, sleep apnea, and narcolepsy.

If you think that you might have a sleep disorder, there are a few things that you can do to find out for sure. First, talk to your doctor about your symptoms. They will be able to rule out any other potential causes of your sleeplessness and refer you to a sleep specialist if needed.

Second, keep a sleep diary in which you track how much sleep you're getting each night and how rested you feel during the day. This will help the specialist determine whether or not you have a sleep disorder.

Lastly, undergo a sleep study in which your sleep is monitored overnight. This will give the specialist a better idea of what's going on while you sleep and whether or not you have a sleep disorder.

If you think that you might have a sleep disorder, don't hesitate to talk to your doctor and get it checked out. It's important to get enough sleep so that you can function at your best!
