Effects of Insufficient Sleep
The 14 things this section of the textbook says that you are most likely to be asked about — quoted word for word, not retold. Then 6 practice questions with the reasoning.
Key points
Broad insufficiency effects
For children, sleep insufficiency may influence growth and development, and, for both children and adults, sleep inadequacy can have behavioral, psychological, and physiological implications.
Child cognitive effects
Inadequate sleep has direct effects on cognitive operations, alertness, the ability to focus and pay attention, the acquisition of vocabulary, and memory (Liu et al., 2024; Pacheco, 2023).
Infant growth hormone
Not enough sleep during infancy can result in secretion of insufficient amounts of growth hormone, therefore potentially impacting normal growth at such a critical time (Pacheco, 2023).
Adolescent cardiometabolic risk
Hypertension, cardiovascular disease, and diabetes mellitus (especially type 2) are becoming more commonplace in adolescence and even childhood, and insufficient sleep is one major factor (Liu et al., 2024; Pacheco, 2023).
Child mental health risk
Children and adolescents who have no history of mental health concerns may experience such issues as depression or anxiety when sleep deprived; those who have an existing mental health diagnosis are at greater risk for such challenges to worsen (Columbia Psychiatry, 2022).
Performance deficits
Possible effects on performance include lack of alertness, inability to concentrate and complete tasks, impaired cognitive and reasoning abilities, poor memory, slowed reaction times, poor development of motor skills, and lack of academic achievement (Liu et al., 2024; Nunez Lamoreux, 2023).
Pediatric obesity mechanism
Research indicates that lack of sleep leads to alterations in hormone regulation, which results in an energy imbalance, a subsequent reduction of activity level, and increased intake of calories.
Adult cognitive outcomes
Chronic sleep insufficiency negatively affects mental and physical health and wellness. Cognitive and behavioral outcomes include decreased reasoning skills; risky, impulsive actions; and poor mood and judgment.
Psychological bidirectionality
Sleep insufficiency is associated with anxiety, depression, concentration, memory, and mood (Suni, 2024). This relationship sometimes occurs in a bidirectional manner, whereby lack of sleep can be both a contributor to, and the effect of, a mental disorder (Columbia Psychiatry, 2022; Suni, 2024).
Concentration and memory
While sleeping, the brain is able to recover from the day’s demands, including those involved in learning, concentration, and memory consolidation (Pacheco, 2023; Suni, 2023).
Cardiovascular implications
Implications can be seen in inflammatory responses and the development of atherosclerosis, hypertension, hyperlipidemia, hyperglycemia/diabetes mellitus (DM), obesity, and subsequent myocardial infarction (MI) and stroke (Cleveland Clinic, 2020; Suni, 2023).
Metabolic syndrome risk
Those who sleep less than five hours, or more than nine hours per day, are at elevated risk for development of metabolic syndrome.
Immune susceptibility
Patients who do not receive the sleep they need are more susceptible to infections, autoimmune reactions, and exaggerated inflammatory responses resulting in infections and chronic inflammatory responses.
Drowsy driving harm
The NSF (2022) estimates that approximately 21 percent of motor vehicle accidents (MVAs) resulting in death are attributable to drowsy driving; about 13 percent of drowsy driving MVAs result in hospitalizations.
Terms to know
- Insufficient sleep
- Insufficient sleep caused by either a total lack of sleep or a lack of quality sleep can affect people in many ways.
- seasonal affective disorder (SAD)
- Other psychological disorders such as ADHD; seasonal affective disorder (SAD), which is depression occurring relative to lack of light; and symptoms of bipolar disorder and schizophrenia can all be adversely affected by insufficient sleep.
- hyperlipidemia
- Obesity tends to be accompanied by metabolic disorders, including insulin resistance and cardiovascular-related concerns such as hyperlipidemia (elevated blood lipids) and dyslipidemia (abnormal blood lipids), hypertension, and coronary artery disease.
- dyslipidemia
- Obesity tends to be accompanied by metabolic disorders, including insulin resistance and cardiovascular-related concerns such as hyperlipidemia (elevated blood lipids) and dyslipidemia (abnormal blood lipids), hypertension, and coronary artery disease.
- PTSD
- PTSD, involving a combination of hyperarousal and recurrent episodes based on trauma, can worsen sleep issues with nightmares and sudden traumatic awakenings (Suni, 2024).
- driving while drowsy
- According to the National Sleep Foundation (NSF, 2022), driving while drowsy equals driving while impaired.

Every question here, with the answer
A 6-year-old who recently started first grade has become irritable at home, was involved in a fight at school, and is now falling behind in reading and spelling. Which nursing assessment is most appropriate?
- Reassure the parent that these changes are expected with school adjustment.
- Tell the parent to add more academic practice before bedtime.
- Assess the child’s sleep pattern and ask about current stressors at school.
- Recommend stricter discipline because the behavior is most likely intentional defiance.
Answer: Assess the child’s sleep pattern and ask about current stressors at school.
Insufficient sleep in children can affect mood, attention, learning, and school performance, and stress can worsen sleep. Assessing sleep and school stressors addresses a likely contributing cycle rather than treating the behavior as simple defiance.
A school nurse is planning education for parents about possible effects of chronic insufficient sleep in children. Which effects should the nurse include? Select all that apply.
- Performance problems at school
- Mental health concerns such as anxiety or depression
- Improved mood regulation and resilience
- Growth and development concerns
- Higher risk for obesity and related health concerns
Answer: Performance problems at school, Mental health concerns such as anxiety or depression, Growth and development concerns, Higher risk for obesity and related health concerns
The section links insufficient sleep in children with growth and development, mental health, behavior, performance issues, and obesity risk. Improved mood regulation is not expected; the section describes difficulty regulating mood and developing resilience.
An adult patient reports chronic insomnia and says, “I don’t have a history of depression, but lately I feel hopeless.” Which nursing action has the highest priority?
- Focus only on sleep hygiene because inadequate sleep does not affect safety.
- Advise the patient that the hopelessness should resolve without further assessment.
- Assess the patient for suicidal risk and report concerning findings to the healthcare provider.
- Explain that suicidal risk is only a concern when depression was diagnosed before insomnia began.
Answer: Assess the patient for suicidal risk and report concerning findings to the healthcare provider.
The section states that inadequate sleep can increase suicidal risk even without a history of depression. Because this is a safety concern, assessment for suicidal risk is the priority over reassurance or sleep hygiene alone.
A nurse is teaching an adult with chronic insufficient sleep about cardiovascular risks. Which conditions should the nurse include as associated risks? Select all that apply.
- Reduced risk for myocardial infarction and stroke
- Obesity
- Hypertension
- Atherosclerosis
- Hyperglycemia or diabetes mellitus
Answer: Obesity, Hypertension, Atherosclerosis, Hyperglycemia or diabetes mellitus
The section identifies atherosclerosis, hypertension, hyperglycemia/diabetes mellitus, and obesity as cardiovascular implications of insufficient sleep. It also states that myocardial infarction and stroke are subsequent risks, not reduced risks.
A patient with reflux, abdominal pain, and bloating reports waking often during the night and feeling worse the next day. Which explanation by the nurse is most accurate?
- Poor sleep improves perceived gastrointestinal symptoms over time.
- Only the timing of sleep matters; sleep quality does not affect gastrointestinal symptoms.
- Gastrointestinal symptoms and sleep problems can worsen each other.
- Gastrointestinal distress is unrelated to sleep quality or sleep duration.
Answer: Gastrointestinal symptoms and sleep problems can worsen each other.
The section describes a bidirectional relationship between gastrointestinal distress and sleep. GI distress can fragment sleep, and shortened sleep can contribute to symptoms such as reflux, pain, and bloating.
A patient reports sleeping very little before driving to work and says, “I can handle it as long as I stay focused.” Which teaching points should the nurse include? Select all that apply.
- Confidence in driving ability is more important than the amount of sleep obtained.
- Safe driving requires recognizing and respecting the effects of drowsiness.
- Drowsy driving belongs with drunk, drugged, and distracted driving as a major driving concern.
- Drowsy driving is a normal inconvenience rather than a safety risk.
- Driving while drowsy should be treated as impaired driving.
Answer: Safe driving requires recognizing and respecting the effects of drowsiness., Drowsy driving belongs with drunk, drugged, and distracted driving as a major driving concern., Driving while drowsy should be treated as impaired driving.
The section emphasizes that drowsy driving is impaired driving and identifies drowsy as the fourth “D” along with drunk, drugged, and distracted. The patient should not rely on confidence or minimize drowsiness as harmless.
