The Real Issues Caused by Sleep Deprivation
The American Sleep Association states that 50 to 70 million adults in the U.S. are
affected by a sleep disorder. According to the CDC, the average adult is recommended to sleep at
least seven or more hours each night. Seven may seem like a high number to most adults, but the
number of hours of sleep increases as age decreases. Sleep is crucial not only for adults but also
for children and teens. Sleep may seem like it would not affect the psychological aspect of the
body, but it can cause a lot of damage. Sleep allows the body to repair itself while consolidating
previously learned information. Without adequate sleep each night, one could gain various
diseases like depression, anxiety, and high blood pressure.
Starting with the different types of sleep deprivation. The first is Acute sleep deprivation
when someone is not getting enough sleep for a short period. Another is chronic sleep
deprivation, which is also known as insufficient sleep syndrome when a person is not getting
enough sleep in the time span of three months or longer. Next is chronic sleep deficiency or poor
sleep and ongoing sleep deprivation, usually because of disruptions at night or sleep
fragmentations. Insomnia is similar to sleep deprivation, but it is somewhat different. People
with insomnia have trouble sleeping even when they have plenty of time for rest, but people with
sleep deprivation do not have enough time allocated for sleep. An example of sleep deprivation
is when a person dealing with a busy work schedule cannot obtain enough time to rest, while a
person who has insomnia has too much free time on their hands and still cannot fall asleep.

Although those aspects are opposites, they both involve an issue with trying to fall asleep, which
can cause severe damage to the body. I will be using insomnia and sleep deprivation to prove
why sleep is so vital for both the mind and body.
A person who does not sleep at least 7 hours a night will show signs of sleep deprivation
such as frequent yawning, irritability, and daytime fatigue. The Healthline states multiple issues
sleep deprivation can cause to someone's physical health. Little to no sleep can affect the
immune system. While a person sleeps, the immune system produces infection-fighting
substances that help fight off foreign invaders like viruses and bacteria. If a person is not getting
enough time to sleep, the body won't be able to create those antibodies to fight off any
sicknesses. Another system that can be affected inside the body is the cardiovascular system
because sleep keeps the blood vessels and heart healthy, affecting blood sugar. Since sleep plays
a vital role in healing the heart and blood vessels, it can help prevent cardiovascular disease. The
Endocrine system can also be negatively affected by sleep deprivation. The endocrine system is
where the production of hormones is created, and if one does not get enough sleep at night, it can
affect the growth hormone production that helps the body build muscle mass and repair tissues
and cells. If that gets too high, it can cause high blood pressure and inflation levels. These are
just a few issues sleep deprivation can cause.
I am going deeper into why the immune system causes these destructive issues and why
sleep is crucial for everyday life. Bodies release proteins called cytokines, and those unfamiliar
cytokines promote sleep. When the body takes in a virus or infection, some cytokines need to
increase to fight diseases and keep the body healthy. When the body does not get enough sleep,
the body will decrease the production of cytokines which can be deadly for the body. Since this
allows bacteria to enter and, like the antibodies, the cytokines can not help; it can lead to long-
Hyland 3
term damage to the body. Instead of a short sickness, the body can cause brain damage and
deteriorate memories, and not only the brain but signs of insomnia will show physically on the
body. Like cytokines, the body also has hormones that control metabolism, appetite, and glucose
processing. When the body is not getting enough sleep each night, the production of cortisol
(stress hormones) will be increased. Cortisols are not the only hormones thrown off; various
other hormones can cause serious issues. The increased cortisol can lead to too much glucose in
the body; Therefore, the body can gain diseases like type two diabetes. Reviewing the body’s
anatomy helps determine the background for why all these issues of lack of sleep can occur.
For example, a significant study published in the journal Nature Communications
followed 8,000 50-year-olds in Britain for 25 years and found that those who slept less than 7
hours were 30 percent more likely than those who got their 7 hours of sleep to get diagnosed
with dementia. New York Times Magazine found that 71,617 women were followed around for a
decade by the Nurses’ Health Study and found that those who slept 8 hours or more had the
lowest risk of developing heart disease. There is plenty of historical evidence to prove sleep is a
crucial aspect of life. Some of the most significant environmental disasters have been caused by
sleep deprivation, such as the nuclear accident at Three Mile Island in 1979, the nuclear
meltdown at Chornobyl in 1986, and the 1989 Exxon Valdez oil spill in Alaska. Thousands of
drowsy drivers cause crashes, injuries, and fatalities every year. Lives are being taken monthly
due to reckless drivers who do not get enough sleep. Sleep can affect a person physically and
mentally, as shown in whoever caused these accidents.
Dan Ford, a Behavioral Sleep Psychologist, reviews more examples of mental health
issues sleep deprivation can have on the body on Healthnavigator. If someone has problems
sleeping, they may feel more anxious, depressed, or suicidal. Even worse than anxiety, there
Hyland 4
could be psychotic episodes triggered by mania (extreme mood changes), paranoia (visualizing
false objects), and or psychosis (affects the brain’s process), all symptoms caused by poor sleep.
There are also links with insomnia and multiple other diseases. First, there is PTSD/trauma, and
sleep deprivation occurs in up to 90% of people who have PTSD since they have gone through
previous trauma, which can affect them majorly in their sleep. Second is Bipolar disorder,
somewhere between 70-90% of people struggle with sleep deprivation and bipolar disorder
because they constantly have racing thoughts when trying to sleep. The third is ADHD; 65% of
adults who experience sleeping problems struggle with ADHD. These issues are caused because
one is too hyperactive, which also affects children detrimentally. These are the most severe
mental health issues that could be brought on by insomnia or sleep deprivation. There are less
severe issues: sleep deprivation and insomnia could cause problems such as struggling to
concentrate throughout the day, feeling lonely or isolated, or feeling super irritable with
everything going on in their lives.
There is research behind the issues that are caused by loss of sleep. Writer Hans P.A Van
Dongen talks about the impact of sleep deprivation on declarative memory in Chapter 2 of his
book, Sleep Deprivation, and Cognition. He states, “Sleep plays a crucial role in memory
stabilization and integration, yet many people obtain insufficient sleep.” He knows how crucial it
truly is because it can lead to problems when consolidating, encoding, and retrieving memories.
When there is an issue with retrieving memories and information, there is a problem with the
neurophysiological process. Looking back on previous studies, Van Dongen found that after
someone learns anything and soon loses sleep post-learning, they will forget the information and
possibly recover it over time. In contrast, they have discovered new studies that find that a
person who can get multiple successful nights of sleep in a row can impair the memories and
Hyland 5
functions of the brain. Some may believe it is okay not to get a consecutive number of hours of
sleep each night, and naps can be just as productive, but that is only somewhat correct.
Afternoon naps can reduce sleepiness while improving vigilance and memory, but it is not
optimal for neurobehavioral functions. Letting the body rest for hours each night is key to a fully
functioning nervous system.
In addition to the other studies on various patients, a study was done on a 13-year-old boy
put in a psychiatry ward in Kohnodai Hospital in Japan. He was admitted by his parents and
diagnosed with obsessive-compulsive disorder. Obsessive-compulsive disorder is a pattern of
unwanted thoughts that lead to repetitive behaviors. The article describes his life and how he
turned from an ordinary boy to an obsessive, aggressive young boy. Later on, the report talks
about how he had difficulty sleeping, which began to affect him mentally. He began overthinking
everything and living in fear of all things living. He went into psychosis and imagined the worst
that could happen to him and his family. Of course, he did have a disorder, but sleep deprivation
came along with the disease and caused him severe mental issues. Similar to previous data, there
was a connection between the boy’s OCD and insomnia, which affected how he thought. He was
not the only poor sour that has to deal with sleep deprivation and other diagnosed diseases all at
once. The boy is a prime example of what can happen to anyone who does not get the correct
amount of sleep per night, and sadly for him, his mind was taken over, and he was no longer
himself. Sleep is vital to all people, no matter their age.
Alan G wade, the author of a published article, states that most people with severe
insomnia remain untreated. This could be because people having constant issues sleeping don’t
realize it is an acute disease that needs to be treated as soon as possible. Although, after one loses
sleep each night consecutively, they should be checked and diagnosed. Some medicines can be
Hyland 6
given to people with insomnia, but they cannot be prescribed if not diagnosed. Previous studies
have found that insomnia and depression are linked, and if one does not already have depression,
insomnia causes a high risk of obtaining depression. Contrastingly, people with depression may
show signs of frequent insomnia, making it very hard to get treated with antidepressants. It has
been found that patients with depression can be hard to contain when they have a high level of
sleep insomnia. Then leads to the noncompliance of the patient under therapy. People with sleep
deprivation and any diagnosed diseases can be hard to treat since the brain cannot function
properly. If a person just gets the suggested amount of sleep per night, there would be no
connections between insomnia and diseases; It could even stop the disease, depending on which
occurs first. The frequent comorbid between insomnia and depression gives another example of
how sleep can affect the mind and its actions.
Subsequently, lack of sleep can lead to many long-term consequences. Getting less than
seven hours of sleep each night can cause elevated hypertension (blood pressure). Of course, the
brain cannot process information correctly with inadequate hours of sleep, but Why? The first
instance to cover is the symptoms of an exhausted brain, such as mental fog, short temper,
fatigue, and a lack of controlled focus. Faulty brain functions can occur because the mental
faculties can decrease drastically when the brain is not getting enough sleep. These functions that
can be taken out by sleep deprivation are reflexes such as motor skills and balance, resulting in
them injuring themselves while trying to move. Without adequate sleep, a person cannot feel as
sharp as they usually do, meaning they cannot concentrate and learn and are deprived of their
problem-solving skills. To add, when the body’s hormones are thrown off, it can cause fertility
problems, and this is because part of the brain controls the circadian rhythms, which releases the
reproductive hormone. When there is a lack of sleep, the hormones are not being produced
Hyland 7
correctly, leading to problems. Anyone who tries to conceive a new baby cannot if they are not
getting enough sleep per night. The impact of sleep can cause more significant issues going into
the future.
Going back to lack of alertness, missing a few extra hours of sleep a night can
considerably impact the day. Since it can cause excessive drowsiness, it could affect the quality
of life, meaning one could feel less up to participating in normal daily activities and having fun.
Impaired memory is another problem sleep deprivation can cause, which affects the brain,
making it hard to retrieve previous memories when speaking to others. If adults want to feel fully
energized for their day and not always moody and exhausted, they should get at least 7 hours of
sleep each night. In addition to talking to people, it can cause stress in any relationship due to the
lack of sleep one slept the night before. A person could feel more moody than usual, which can
cause conflict with anyone they come into contact. Those are just short-term issues; chronic
sleep deprivation can cause long-term problems like diabetes, heart failure, heart attack, or
stroke. Again along with reduced immune system functions, lack of sleep can lead to obesity and
premature wrinkles and dark circles under the eyes. Evidence proves sleep can not only affect the
brain but also the physical appearance of a person.
Apart from this, I will continue investigating the possible diseases caused by sleep
deprivation. The first I have already covered is diabetes, but this can happen because people who
tend to sleep less do not allow their bodies to regulate those blood sugars, which can cause a high
risk of metabolic conditions. It can be hard to maintain a healthy weight when one is getting poor
sleep each night because insomniacs tend to consume more calories and carbohydrates, which
can cause high percentages of fat within the body. As previously stated, the immune system can
be affected, leading to immunodeficiency, which means the worsening of the immune system. A
Hyland 8
weakened immune system does not sound like the worst possible outcome of poor sleep, but it
can cause the person to become very sick and cause them to have poor reactions to vaccinations
that are supposed to help them, not hurt them. Without enough time for the body to repair itself,
it can make a person’s bones feel weak and their body altogether. Weak bones can cause
significant pain when trying to do normal daily activities or even falling asleep at night, causing
less and less sleep over time. This is the opposite of what they would need since they are
substantially in need of rest. The most extensive connection sleep can be tied to is death! These
critical impacts on the body scream to people to get a good night’s sleep each night.
As stated above, I will follow up on the most prominent concern sleep can cause the
connection between sleep deprivation and death. The risk of disease is the most significant
reason not enough sleep can lead to things such as death, but there are various other reasons as
well. It is proven that people who get the right amount of sleep each night, not too little nor too
small, tend to live happier longer lives. Other symptoms of sleep depression are fatigue,
irritability, headaches, slow physical and mental reaction time, and trouble concentrating. These
symptoms can lead to worse illnesses, but the essential aspect of life is happiness, and someone
who is struggling with these issues is not thriving in life. Someone living in this world struggling
with sleep deprivation is not living to their total ability because when they are always tired and
the mind is not processing correctly, life is just dull. When a person begins to think negatively
about any aspect of life, they may start to consider suicide or eventually cause death from their
depression. Another example I have previously stated could go along with this fact, but a
decrease in sleep can increase the risk of car accidents both night and day. The safest way to live
each day can only be lived when one gets enough sleep per night.
Hyland 9
I will further detail why others may see sleep in a different perception. Some may
believe sleep can cause drowsiness and the mind should get less sleep; they may consider this
because if they get too much sleep during the day after taking a nap or going to bed way earlier
than usual, it can cause them to wake up less alert. This makes sense because that can happen,
but they have to think about the body itself and how it functions. The central part that controls
everything in the body is the brain, and overnight the brain rest and allows the body to repair
itself and rest. Without proper sleep, it will not allow the body functions because it is deprived of
sleep. Most of these problems come from naps in the middle of the day since the brain does not
have enough time to repair; this proves that naps do not allow the body to have optimal
neurobehavioral functions. When one does not get enough sleep the night before, a nap will
release serotonin in the body, leading to disruptions in their nighttime sleep the night after,
leading to headaches and pain in the brain the morning after. After looking at my opinion, it is
also a fact that if someone gets too much sleep, it could cause chronic diseases like coronary
heart disease. But overall, people are more at risk for all other diseases sleep deprivation can
cause. Too much sleep can be inadequate for the body, but the right amount of seven hours each
night would benefit the body optimally.
Studies prove that a person can not live without optimal sleep each night. Rest is needed
because it can lead to long-term effects on the body. It can cause physical health problems with
your immune system, cardiovascular system, and endocrine system, which can cause more long-
term severe physical issues like heart disease, diabetes, high blood pressure, obesity, and strokes.
Sleep deprivation and insomnia can cause mental problems such as depression, anxiety,
irritability, stress, and mood disorders like bipolar disorder. Other than the systems in the body, it
can cause drowsiness which can affect your mood and your aspect of life, which can cause
Hyland 10
suicidal thoughts due to depression. Seven hours of sleep is recommended for all adults for their
mental and physical health.
