Think of your body like a phone—it needs to recharge at night! But sleep isn’t just about plugging in. It’s about your body repairing itself and getting ready to crush that next hectic day.
The problem is that, with all the stress, homework, and late-night social media scrolling, many students miss out on quality sleep. That is why we have decided to help you RELAX.
This article will explore why the science of sleep matters to students like you. We will cover the following points in this article:
- What is sleep?
- Why is sleep important?
- Stages of sleep
- Sleep disorders
- Tips for a deep sleep
Let’s Explore the Science of Sleep in Detail
1. What is the Science of Sleep?
To understand the basic science of sleep, you must first learn what sleep is.
Simply put, sleep is when your body takes a break and rests. It’s a state where you become less aware of what’s happening around you, and your body goes through expected changes. It’s an important part of staying alive and healthy.
“Interesting fact alert: Did you know that we spend one-third of our lives sleeping or attempting to sleep?”
Now that you know what sleep is, let us proceed to how the human body falls asleep:
Internal Clock: Your brain has a natural “sleep-wake cycle” controlled by light. As darkness falls, a pea-sized gland called the pineal gland kicks in, producing melatonin, a sleep hormone. Melatonin makes you drowsy.
Winding Down: Your body temperature drops slightly, muscles relax, and brainwaves slow down. You might feel sluggish and ready to doze off.
Drifting Off: You enter Stage 1 of sleep, a very light sleep where you can be easily awakened. The brainwave activity slows further, and your eyes might slowly move from side to side.
Deeper Sleep: As you progress through stages 2, 3, and 4 of non-REM sleep, your body enters a deeper sleep state. This is when your body does important repair work.
Dream Time: About 90 minutes after falling asleep, you enter REM (rapid eye movement) sleep. This is the stage where you dream.
2. Why is Sleep Important for Students?
Sleeping well every day is very important for students. If you, as a student, sleep well, it will benefit you both mentally and physically.
Notably, the science of sleep says that a healthy sleep schedule for students helps them build stronger memories and enables them to learn better.
Your brain absorbs and combines the knowledge you acquire during the day while you sleep, which facilitates its recollection and application the following day.
On the flip side, insufficient sleep hurts academic performance. Students who don’t get enough sleep may have trouble focusing, paying attention, and solving problems, which can result in subpar academic performance and setbacks.
Apart from these factors, good sleep benefits the body in the following ways:
- Good sleep keeps us emotionally stable. Poor sleep can make us moody and stressed.
- Sleep aids in focus, decision-making, and problem-solving. Lack of sleep makes these harder.
- Our bodies repair and grow during sleep. Good sleep lowers the risk of diseases.
- Sleep regulates heart function and blood pressure. Not sleeping enough can lead to heart problems.
- Sleep strengthens our immune system to fight off illnesses.
3. The 4 Stages of Sleep
Now that you know the benefits of sleep, we will explore the four stages of sleep in detail:
- NREM (Stage 1)
NREM 1 is like the light stage of sleep. It’s the very first stage you enter when drifting off. Your heart rate, breathing, and brainwaves slow down compared to when you’re awake.
During this stage, your sleep is light. Notably, you might experience little body twitches called hypnic jerks.
- NREM (Stage 2)
In NREM 2, you drift further away from wakefulness. Your brain waves slow down even more. Your heart rate and breathing become steadier, and your body temperature drops a bit.
It’s still a fairly light sleep stage, so loud noises or someone shaking you might wake you up more easily.
- NREM (Stage 3)
During the NREM 3 deep sleep stage, your slumber is deep. Your body goes into full chill mode. Heartbeat, breathing, and muscle activity slow way down. This is when your body focuses on fixing itself.
Notably, it’s really hard to wake up from this stage. Loud noises might not even faze you. Lastly, your brain produces special slow waves that help with this deep sleep and restoration process.
- REM Sleep (Stage 4)
The REM stage of sleep is the dream zone! Your brain becomes super active at this stage. This is why you have vivid dreams during REM sleep. Your eyes dart around really fast under your eyelids, even though you can’t see anything. This is where the name REM (rapid eye movement) comes from.
Moreover, your muscles are basically paralyzed to stop you from acting out your dreams. Lastly, your heart and breathing speed up a bit.
Importantly, did you know that people experience heart problems in the REM stage?
4. Different Types of Sleep Disorders
Now that you know the basics of the science of sleep, let’s understand why you may not be able to sleep at night. While it’s possible that you may not get a good night’s sleep due to stress, anxiety, sleeping late at night, drinking tea or coffee at night, etc., it’s also possible that you probably suffer from a sleep disorder.
Reading this part will help you figure out if you have any sleep disorders.
“Before we list down the major and most common sleep disorders, did you know that there are over 80 types of sleep disorders?”
The most common sleep disorders are:
- Chronic Insomnia: Difficulty falling asleep or staying asleep for at least three months, leading to tiredness and irritability.
- Obstructive Sleep Apnea: Snoring and interrupted breathing during sleep, causing disruptions.
- Restless Legs Syndrome: The uncontrollable urge to move legs while resting.
- Narcolepsy: The inability to regulate sleep timing or duration.
- Shift Work Sleep Disorder: Trouble sleeping due to work schedule, leading to unwanted sleepiness.
- Delayed Sleep Phase Syndrome: falling asleep significantly later than desired bedtime.
- REM Sleep Behavior Disorder: Acting out dreams during REM sleep.
Some of the common symptoms used to identify these disorders are:
Firstly, the night-time symptoms are:
- Regularly taking more than 30 minutes to fall asleep.
- Waking up often during the night and struggling to fall back asleep.
- Snoring, gasping, or choking occurs during sleep.
- Feeling the need to move when relaxing, with movement relieving the sensation.
- Feeling unable to move upon waking up.
Secondly, the daytime symptoms:
- Frequent daytime naps or falling asleep during routine tasks.
- Difficulty focusing or paying attention.
- Irritability and emotional management challenges.
- Difficulty meeting deadlines or expectations.
- Increased risk due to inadequate sleep.
5. Effective Tips to Sleep Well
As we now come to the last chapter of exploring the science of sleep, let us now explore some effective remedies for you to tackle your problem.
As a student, you can try the following tips to get good sleep:
Prepare Your Brain for Sleep: You must carefully think and plan when to sleep and when to wake up. For example, if you say, “I will sleep at 10:30,” then make sure to follow that. If your pattern is disturbed due to exams or other events, that’s okay.
Prepare Your Brain for Sleep: Give yourself around 30 minutes to fall asleep prior to bedtime. For example, lie on your bed at 10 if you sleep at 10:30.
Avoid Coffee and Alcohol: Coffee and alcohol are two beverages that can totally ruin your sleep. These two can disrupt the process of NREM 3, which is the deep sleep process. Avoid these drinks before you sleep.
Avoid Gizmos: If you think seeing your mobile is going to help you before you sleep, you’re wrong. According to studies, utilizing these devices in the bedroom can pose health risks.
Get Plenty of Exercise: No play and only sitting make Jack a sleepless boy. Yes, a lack of physical activity during the day can also make you less sleepy. This is because, since your body isn’t tired, your mind thinks it doesn’t need to sleep. So, run!
Meditate or Pray: Lastly, drop your thoughts. Any sort of anxiety or stress can disturb your sleep. So, meditate or pray for 20 minutes daily before you sleep. It helps the mind relax fully.
