REVIEW OF RELATED LITERATURE AND STUDIES
Sleep deprivation is a condition characterized by a lack of sufficient sleep, which can cause a
range of negative effects on physical and mental health. The following is a review of some of
the latest research findings and literature on sleep deprivation.
Statistics OF SLEEP DEPRIVED STUDENTS
A study published in the Philippine Journal of Otolaryngology Head and Neck Surgery in 2020
found that sleep deprivation is a common problem among medical students in the Philippines.
The study found that 56.1% of participants experienced sleep deprivation, and that this was
associated with high levels of stress and poor academic performance.
A review published in the Philippine Journal of Internal Medicine in 2020 examined the impact
of sleep deprivation on cardiovascular health. The review found that sleep deprivation is
associated with an increased risk of hypertension and cardiovascular disease, and that
improving sleep quality could be an effective strategy for preventing these conditions.
A study published in the Philippine Journal of Nursing in 2021 examined the prevalence and
correlates of sleep deprivation among nurses in the Philippines. The study found that 69.4% of
nurses experienced sleep deprivation, and that this was associated with shift work and high
levels of job stress.
A survey conducted by the Philippine Statistics Authority in 2019 found that 47.5% of Filipinos
aged 18 years and older reported getting less than the recommended 7-9 hours of sleep per
night. The survey also found that sleep duration was lower among those with lower income and
educational attainment
A study published in the Philippine Journal of Psychology in 2019 examined the relationship
between sleep quality and mental health among Filipino college students. The study found that
poor sleep quality was associated with higher levels of depression and anxiety symptoms.
Overall, these studies suggest that sleep deprivation is a common problem in the Philippines,
particularly among students and healthcare workers. Sleep deprivation is associated with a
range of negative health outcomes, including poor academic and job performance,
cardiovascular disease, and mental health problems. It is important for individuals to prioritize
getting sufficient sleep and for employers and policymakers to implement strategies to improve
sleep quality and duration.
Causes of Sleep Deprivation Among High School Students
ACCORDING TO {NEWPORT ACADEMY 2022] For most adolescents, nine hours of sleep is ideal,
but very few of them are actually managing that. One study conducted by the Centers for
Disease Control showed that less than 9 percent of teens get enough. Here are some of the
causes of teen sleep deprivation .Technology that affects teen sleep, such as social media,
Internet use, video games, and television After-school activities that push study times later,
Heavy homework loads, Schools with early start times, Using caffeine or nicotine,Stress,Light
exposure from screens that cues the brain to stay awake.
Effects of Sleep Deprivation on the Teenage Brain
Lack of rest has a negative impact on the functioning of the emotional regulation circuit of the
brain. In studies conducted by [Matthew T. Feldner 2015 ], a professor of psychology at the
University of Arkansas, people who lost a night of sleep responded with more emotion to
stressors presented in the lab.
A study of [NATIONAL LIBRARY OF MEDICINE 2013] examined how teenagers reacted during the
day when they hadn’t gotten enough sleep. Sleep-deprived teens found stressful situations
much more threatening than the more mature study participants.Furthermore, researchers
have found that sleep-deprived teens feel more depressed and anxious. In a study of nearly
28,000 high school students, each hour of lost rest was associated with a 38 percent increase in
the risk of feeling sad or hopeless, and a 58 percent increase in suicide attempts. Another study
found that high school seniors were three times more likely to have depression symptoms if
they had excessive daytime sleepiness.
NEGATIVE EFFECT OF SLEEP DEPRIVED
A study published in the [journal Sleep 2020] found that even short-term sleep deprivation can
have negative effects on cognitive and emotional functioning. The study found that participants
who were sleep-deprived for just one night performed worse on cognitive tasks and had
increased negative mood compared to those who had a full night's sleep.
Another study published in the[ journal Sleep in 2021] examined the impact of chronic sleep
deprivation on brain function. The study found that chronic sleep deprivation can lead to
changes in brain structure and function, which can result in cognitive impairment and mood
disorders.
A review published in the[ journal Current Opinion in Pulmonary Medicine in 2021] examined
the relationship between sleep deprivation and respiratory diseases. The review found that
sleep deprivation can worsen respiratory symptoms and increase the risk of respiratory
diseases, including obstructive sleep apnea and chronic obstructive pulmonary disease.
A study published in the [journal Sleep Medicine Reviews in 2021] reviewed the impact of sleep
deprivation on the immune system. The study found that sleep deprivation can impair immune
function, leading to increased susceptibility to infections and other diseases.
Finally, a review published in the [journal Current Opinion in Psychiatry in 2021] examined the
relationship between sleep deprivation and mental health. The review found that sleep
deprivation can increase the risk of developing mental health disorders, such as depression and
anxiety, and can worsen symptoms in individuals who already have these conditions.
Overall, the latest research suggests that sleep deprivation can have a range of negative effects
on physical and mental health, including impairments in cognitive function, mood disorders,
respiratory diseases, immune dysfunction, and mental health disorders. As such, it is important
to prioritize getting sufficient sleep to maintain optimal health and well-being.
Sleep-Deprived Teens, Substance Abuse, and Risky Behavior
Another reason why sleep is important for teens is because sleep deprivation can increase their
likelihood of using drugs and alcohol. A study published in the [Journal of Youth 2021] and
Adolescence indicates that the disruption of the natural sleep cycle can significantly increase
the risk of substance use, by interfering with brain functions that regulate the experience of
reward, emotions, and impulsivity.
Sleep-deprived teens tend to engage in risky behaviors because their impulse control is
compromised. The National Center on Addiction and Substance Abuse statistics show that high
school students who get less than eight hours of sleep per night are significantly more likely to
use alcohol, smoke marijuana, and become lifetime users of illegal drugs. One study
[Prospective relationship between poor sleep and substance-related problems in a national
sample of adolescents] found that sleep deprivation is linked to binge drinking, drunk driving,
and unprotected sex
