Autism Spectrum Disorder (ASD) and Sleep

Sleep is a major issue for many adults and children who have been diagnosed with autism spectrum disorder (ASD). Recent studies suggest that up to 80% of young people with ASD also have difficulty falling and/or staying asleep at night. The incidence rate of sleep problems and disorders is also high among adults with ASD, particularly those who are classified as ‘low-functioning’. Lack of sleep can exacerbate some of the behavioral characteristics of ASD, such as hyperactivity, aggression, and lack of concentration. As a result, people with ASD who have a hard time sleeping may struggle at work or in their classroom.

We’ll look at some of the most common sleep issues among adults and children with ASD, as well as some suitable treatment options and tips for managing ASD and sleep on a regular basis. First, let’s look at how the medical and psychiatric communities currently define ASD.

What Is Autism Spectrum Disorder?

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) is considered the most authoritative guide for evaluating and diagnosing mental health disorders in the United States. According to the latest definition (last revised in 2013), the diagnostic criteria for autism spectrum disorder (ASD) are as follows:

  • ‘Persistent deficits’ in communication and social interaction that occur in multiple settings. These deficits may a lack of engagement in back-and-forth conversation, ‘abnormal’ approaches to social interaction, and failure to respond to social invitations. ‘Poorly integrated verbal and nonverbal communication’ is another common deficit; this may be accompanied by irregular eye movements, nervous tics, lack of facial expression, and other physical signs. Finally, people with ASD often have deficits in ‘developing, maintaining and understanding’ different types of relationships.
  • Restricted, repetitive behavioral patterns. These patterns may be manifested in motor movements, speech, or use of everyday objects. Common examples of these tendencies include constantly lining up objects in the same manner, mimicking the speech of others (known as echolalia), or repeating ‘idiosyncratic’ phrases. People with ASD may also be unreasonably rigid about breaking from these patterns, and may express dismay when asked to do so. They also demonstrate ‘highly fixated’ interest on specific subjects, as well as ‘hyper- or hyporeactivity’ to sensory factors in their environment (such as smells and/or sounds).
  • Although many people are diagnosed and treated for ASD as adults, symptoms must be or have been present during the early development period.
  • The symptoms must be serious enough to cause ‘clinically significant impairment in social, occupational, or other important areas of current functioning’.
  • The symptoms are not ‘better explained’ by the presence of another condition, such as an intellectual disability or a global development delay. The DSM-5 notes that ASD and intellectual disabilities are often co-morbid, or simultaneously present, in children and adults. However, both classifications carry different sets of diagnostic criteria.

The latest DSM revisions also note three distinct ‘severity levels’ that can be used to assess how much support (if any) a person with ASD requires on a regular basis.

Severity Level Social Communication Restricted Interests and Repetitive Behaviors
Level 3: Requiring Very Substantial Support ‘Severe deficits in verbal and nonverbal social communication skills cause severe impairments in functioning; very limited initiation of social interactions and minimal response to social overtures from others’. ‘Preoccupations, fixated rituals and/or repetitive behaviors markedly interfere with functioning in all spheres. Marked distress when rituals or routines are interrupted; very difficult to redirect from fixated interest or returns to it quickly’.
Level 2: Requiring Substantial Support ‘Marked deficits in verbal and nonverbal social communication skills; social impairments apparent even with supports in place; limited initiation of social interactions and reduced or abnormal response to social overtures from others’. ‘[Rituals and repetitive behaviors] and/or preoccupations or fixated interests appear frequently enough to be obvious to the casual observer and interfere with functioning in a variety of contexts. Distress or frustration is apparent when RRB’s are interrupted; difficult to redirect from fixated interest’.
Level 1: Requiring Support ‘Without supports in place, deficits in social communication cause noticeable impairments. Has difficulty initiating social interactions and demonstrates clear examples of atypical or unsuccessful responses to social overtures of others. May appear to have decreased interest in social interactions’. ‘Rituals and repetitive behaviors (RRB’s) cause significant interference with functioning in one or more contexts. Resists attempts by others to interrupt RRB’s or to be redirected from fixated interest’.

Previous Definitions

Prior to 2013, ASD was broken down into different autism subtypes based on severity of symptoms. These subtypes were eliminated and omitted from the DSM-5, and their diagnoses have all been absorbed into the ‘ASD’ definition. Although these subtypes are no longer officially diagnosed, they are still widely discussed within the medical and psychiatric communities. Additionally, some are still included on other authoritative lists, such as the International Statistical Classification of Diseases and Related Health Problems (ICD) database maintained by the World Health Organization (WHO). The four most common subdivisions of ASD (as previously defined by the DSM) are:

  • Asperger syndrome: Asperger was once considered the mildest incarnation of ASD. Children and adults with Asperger display symptoms like inability to pick up on social cues, hypersensitivity to sensory stimuli, and preoccupations with hyperfocused areas of interest. However, many people with Asperger are high-functioning.
  • Autistic disorder: This was once considered a middle-of-the-spectrum condition. Symptoms are more intense than those in people Asperger, but less severe than the most debilitating forms of autism.
  • Childhood disintegrative disorder: This was considered the rarest — and most severe — form of autism prior to the DSM-5 revision. Most often diagnosed in children between the ages of two and four, CDD was characterized by strictly limited social, speech, and cognitive abilities. Many children with CDD also developed seizure disorders.
  • Pervasive development disorder, not otherwise specified: PDD-NOS was essentially a term for any autism spectrum condition that didn’t meet strict criteria for one of the three disorders mentioned above. As a result, symptoms for PDD-NOS ranged from milder than Asperger to more severe than CDD.

In addition, some disorders once considered part of the autism spectrum were removed from the ASD diagnostic criteria prior to the DSM-5 revision in 2013. Rett syndrome, for instance, can cause symptoms in children that are similar to those associate with autism; however, Rett syndrome is caused by a genetic mutation, and also carries symptoms not found in other ASD disorders. Social communication disorder is another example; people with SCD often struggle with everyday communication, but the disorder is distinguished from ASD due to a lack of repetitive behavior patterns.

The root cause of ASD remains unknown, though most researchers today believe that both genetic and environmental factors play a major role. Recent studies have pinpointed some genes that are prevalent in people with the disorder, and brain-imaging tests indicate that the brains of people with ASD develop differently than the brains of other individuals. The general consensus is that ASD originates from defects in the brain that affect how the brain grows and communicates with other areas of the body. Studies have yet to identify any specific environmental factors that directly cause or influence the development of ASD. However, the scientific community has debunked and rejected the longstanding belief among parents that child vaccinations lead to a higher incidence rate of ASD in developing children.

Diagnosing ASD in Children

Most children with ASD begin to display symptoms by age three, so early detection and evaluation is critical. The ASD diagnosis process for children is divided into two stages: developmental screening and comprehensive diagnostic evaluation.

Parents are urged to begin developmental screening at a young age to evaluate their children for ASD and other intellectual disabilities. The Centers for Disease Control (CDC) recommends ASD screenings for all children at the ages of nine, 18, and 24-30 months, adding that a reliable ASD diagnosis can usually be made by age two. Additional testing may be required for children who are considered high-risk for ASD, including those with family members who have already been diagnosed or those who have displayed ASD-related behaviors.

During the developmental screening stage, doctors watch for signs and symptoms of ASD diagnostic criteria. These include deficits in communication and social interaction, restricted interests, and repetitive behaviors. Speech and language skills are often delayed in children with ASD; they typically will not respond to their own name after 12 months. Other ‘red flags’ include refusal to acknowledge or point at moving objects after 14 months, showing little interest in playing ‘pretend’ games after 18 months, and sustained repetition of words and phrases, as well as physical signs like avoiding eye contact, constantly rocking back and forth, compulsory hand waving, and/or exhibiting ‘unusual’ reactions to sensory stimuli. Additionally, children with ASD often display at least one of the following traits or behaviors:

  • Hyperactivity
  • Impulsive actions
  • A limited or short attention span
  • Aggression and tantrums
  • Self-injury or self-harm tendencies
  • Abnormal eating or sleeping patterns

According to the CDC, the most commonly used developmental screening tools include the following:

  • Ages and Stages: This series of 19 questionnaires focuses on the child’s communication, motor skills, and other areas of development. The questionnaires are age-specific, allowing doctors to evaluate children as specifically as possible.
  • Communication and Symbolic Behavior Scales (CSBS): This ‘Infant-Toddler Checklist’ evaluates children based on the following criteria: emotion and eye gaze; communication; gestures; sounds; words; understanding; and object use.
  • Modified Checklist for Autism in Toddlers (MCHAT): This questionnaire features 23 ‘yes or no’ questions related to the toddler’s interests, speech, motor skills, and behavior. The questionnaire is scored on a scale of 0 to 20, with 20 being considered extremely high risk.
  • Parents’ Evaluation of Developmental Status (PEDS): This evidence-based screening evaluates children based on ‘language, motor, self-help, early academic skills, behavior and social-emotional/mental health.’
  • Screening Tool for Autism in Toddlers and Young Children (STAT): Designed for children between the ages of 24 and 36 months, this evaluative test consists of 12 separate segments; most children complete the screening within 20 minutes.

If developmental screening yields results that are consistent with ASD symptoms, then a comprehensive diagnostic evaluation may be recommended. Family participation during this second phase is vital. Parents can describe symptoms and behaviors to the evaluation provider, who can then take these statements into account when conducting the diagnosis. The presence of at least one parent can ease the evaluation process for the child, as well.

In order to perform an accurate evaluation of ASD in children, doctors rely on a set of diagnostic tools. The CDC notes that a comprehensive ASD evaluation should include at least two diagnostic tools; the following four diagnostic tools are most widely used:

  • Autism Diagnosis Interview-Revised (ADI-R): Used to evaluate children 18 months or older (as well as adults), the ADI-R interview includes specific questions related to social communication and interaction, restricted interests, and repetitive behaviors.
  • Autism Diagnostic Observation Schedule-Generic (ADOS-G): This ‘standard measure of social and communication deficits’ consists of four 30-minute evaluation modules based on the subject’s expressive language abilities.
  • Childhood Autism Rating Scale, Second Edition (CARS2): This scale designed for children two and older is designed to achieve two ends: distinguish symptoms between ASD and other disabilities; and gauge the severity level of ASD symptoms. Different tests are administered based on the subject’s functionality level, and the assessor rates the child based on frequency, duration, and intensity of each ASD diagnostic criterion.
  • Gilliam Autism Rating Scale – Second Edition (GARS-2): This evaluation tool for teachers and clinicians can be used to evaluate anyone between 3 and 22 years of age. The 42 items on the scale are grouped into three categories: stereotyped behavior; communication; and social interaction.

Once the comprehensive diagnostic evaluation is complete, parents can discuss the outcome with their physician and — if the child receives an ASD diagnosis — explore possible treatment options.

Considerations for Diagnosing ASD in Adults

ASD is a lifelong condition. People with ASD typically begin to show symptoms of the disorder during their early childhood. In some cases, however, these symptoms will not become apparent until the individual has reached adulthood.

Due to the wide range of symptoms and severity levels, diagnosing ASD in adults can be a tricky process — particularly for those who have not received an ASD diagnosis as children. According to neurologist David Beversdorf of the Autism Speaks Autism Treatment Network, an adult seeking an ASD evaluation should first discuss the matter with his or her physician. During this consultation, the patient should explain why they are seeking an ASD diagnosis. These reasons may include changes in the way he or she behaves or interacts with others, as well as heightened sensitivity to sensory factors, acquired repetitive behaviors, or newly restricted interests.

Most licensed physicians are not trained to diagnose ASD themselves, but they will be able to steer the patient in the right direction — and, in some cases, refer them to a specialist with a background in ASD diagnosis. Due to a widespread scarcity of clinicians that specialize in ASD, Dr. Beversdorf suggests meeting with a medical professional that evaluates and treats young people for the disorders. These include developmental pediatricians, child psychiatrists, and pediatric neurologists.

One major issue for diagnosing adults with ASD has been a lack of reputable screening and diagnostic evaluation tools. With the exception of the Gilliam Autism Rating Scale — which evaluates subjects up to 22 years of age — these tools are designed for child subjects, not adults, who tend to be less honest and more secretive when undergoing these tests. Deceased parents are another obstacle for diagnosing adults, since mothers and fathers provide key information to clinicians during the early screening and evaluation stages of child ASD testing.

The Adult Repetitive Behaviours Questionnaire-2 (RBQ-2A) appears to be a step in the right direction. Introduced by the Journal of Autism and Developmental Disorders in 2015, the ADBQ-2A is designed to evaluate adults based on repetitive behaviors and restricted interests. Because the questionnaire excludes social communication and interaction, it should not be seen as a definitive evaluation tool for ASD in adults. However, RBQ-2A can be used to help adults decide whether their behaviors and interests are indicative of a disorder that may necessitate formal treatment.

How Does ASD Affect Sleep?

A 2009 study published in Sleep Medicine Reviews noted parents report sleep problems for children with ASD at a rate of 50% to 80%; by comparison, this rate fell between 9% and 50% for children that had not been diagnosed with ASD. The rate for children with ASD was also higher than the rate for children with non-ASD developmental disabilities.

In a recent study titled ‘Sleep Problems and Autism’, UK-based advocacy group Research Autism noted that the following sleep issues are common among children and adults with ASD.

  • Difficulty with sleep onset, or falling asleep
  • Difficulty with sleep maintenance, or staying asleep throughout the night
  • Early morning waking
  • Short-duration sleeping
  • Sleep fragmentation, characterized by erratic sleep patterns throughout the night
  • Hyperarousal, or heightened anxiety around bedtime
  • Excessive daytime sleepiness

The study also pinpointed several underlying causes for these sleep problems that are directly or indirectly related to the individual’s ASD diagnosis. These include:

  • Irregular circadian rhythm: The circadian rhythm is the 24-hour biological clock that regulates the sleep-wake cycle in humans based on sunlight, temperature, and other environmental factors. The circadian rhythm is processed in the brain, and many people with ASD also exhibit irregularities with their sleep-wake cycle. Additionally, some studies have noted a link between children with ASD and irregular production of melatonin, a natural hormone that helps regulate circadian rhythm.
  • Mental health disorders: Conditions like anxiety and depression are often co-morbid with ASD; these conditions often lead to insomnia and other sleep disorders. Studies have also suggested that as many as half of all children with ASD also exhibit symptoms of attention-deficit hyperactive disorder (ADHD), which can cause elevated moods around bedtime.
  • Medical problems: Epilepsy is often co-morbid with ASD, and seizures can greatly impact sleep — even on a regular basis, in severe cases. Other common medical issues among people with ASD include constipation, diarrhea, and acid reflux.
  • Medication side effects: People with ASD who take medication may experience side effects that interfere with sleep. Selective serotonin reuptake inhibitors (SSRIs), for instance, may cause agitation and hyperactivity prior to bedtime. Antipsychotics like haloperidol and risperidone, on the other hand, may cause excessive drowsiness during the day that leads to sleep onset and sleep maintenance problems. Please scroll down to the ‘Treatment’ section for more information about ASD medications.

People with ASD often struggle with daily pressures and interactions more than individuals who do not live with the disorder. Lack of sleep can greatly exacerbate the feelings of distress and anxiety that they experience on a frequent basis. As a result, may people with ASD who have trouble sleeping may struggle greatly with employment, education, and social interaction — all of which can impact their outlook on life.

Persistent sleep problems in people with ASD may indicate a sleep disorder. Insomnia is the most commonly reported sleep disorder among adults and children with ASD. Insomnia is defined as difficulty falling and/or remaining asleep on a nightly or semi-nightly basis for a period of more than one month. A study published in Sleep found that 66% of children with ASD reported insomnia symptoms. A similar study from 2003 found that 75% to 90% of adults then-diagnosed with Asperger syndrome reported insomnia symptoms in questionnaires or sleep diaries.

In addition, parasomnias such as frequent nightmares, night terrors, and enuresis (bedwetting) have been widely reported among children with ASD, particularly those once diagnosed with Asperger syndrome. The child’s inability to express their fears and discomforts upon waking — often due to ASD — can complicate the way parasomnias are addressed and treated. Additionally, children with ASD often wake up in the middle of the night and engage in ‘time-inappropriate’ activities like playing with toys or reading aloud.

Sleep researchers are currently studying the relationships between other sleep disorders and ASD. For example, Dr. Steven Park recently noted a possible connection between ASD and obstructive sleep apnea (OSA), a condition characterized by temporary loss of breath during sleep resulting from blockage in the primary airway that restricts breathing. Dr. Park’s theory suggests that the intracranial hypertension found in many babies and infants with ASD may also cause the child’s jaw to take on an irregular shape, which can lead to sleep-disordered breathing as well. Other studies have explored the link between ASD and disorders like narcolepsy and REM Behavior Disorder. However, insomnia and parasomnias remain the most common sleep disorders among adults and children with ASD.

Next let’s look at treatment options and considerations for adults and children with ASD who are experiencing a sleep disorder.

Since the mid-20th century, prescription medications have been widely used to treat insomnia and other sleep disorders. The general consensus among today’s physicians is that sedative-hypnotic z-drugs, or nonbenzodiazepines, are the most effective pharmacological option for treating sleep disorders. The three most common Z-drugs — zolpidem (Ambien), zopiclone (Lunesta), and zaleplon (Sonata) — induce sleepiness without disrupting sleep architecture, unlike benzodiazepines like alprazolam (Xanax) and diazepam (Valium), which can actually worsen sleep disorder symptoms in some patients.

However, z-drugs and other prescription medications may be problematic for people with ASD. These drugs carry high dependency risks, and may cause side effects that exacerbate ASD-related physical problems like acid reflux and constipation. Additionally, sleep-inducing drugs may interact with other medications designed to help people with ASD feel more alert and focused throughout the day. The bottom line: people with ASD should consult their physician to discuss their current medication schedule before taking any sort of sleep medication.

Children with ASD are particularly susceptible to the dependency risks and negative side effects of sleep pills, so prescription drugs should be considered a last resort for them. If parents suspect their child with ASD has a sleep disorder, then a preliminary assessment should be their first course of action. These assessments may consist of actigraphy, where the child wears a sleep monitor on their wrist that tracks sleep-wake cycles, or PSG, which monitors neurological and cardiovascular activities during sleep. During this assessment, parents can help physicians rule out other factors that may be affecting their child’s sleep. These factors include medical issues like tonsillitis, swollen adenoids, epilepsy, and food allergies, as well as any medications they may be taking for ASD or ADHD.

Side Effects of Common ASD Medications

It’s important to consider that many medications used to relieve ASD symptoms may be negatively impacting the sleep of those who take them. The table below lists some of the most commonly prescribed drugs used to alleviate repetitive behaviors, hyperactivity, inattention, and other symptoms of ASD, along with their sleep- and non-sleep-related side effects.

Medication Trade Name What It Treats Can It Cause Insomnia or Disturb Sleep? Other Side Effects
Risperidone Risperdal Irritability and aggression, aberrant social behavior Yes Weight gain, constipation, diarrhea, nausea
Aripiprazole Abilify Irritability and aggression Yes Weight gain, nausea, upper respiratory tract infection
Clozapine Clozaril Irritability and aggression Yes Weight gain, tachycardia, constipation, enuresis, frequent nightmares
Haloperidol Haldol Irritability and aggression, aberrant social behavior Yes, but rarely Hypotension, constipation, dry mouth, muscle rigidity
Sertraline Zoloft Irritability and aggression Yes Elevated energy levels, poor concentration, diarrhea
Oxytocin Pitocin Aberrant social behavior No Elevated blood pressure, nausea, vomiting
Methylphenidate Ritalin Hyperactivity and inattention Yes Appetite suppression, dry mouth, anxiety, nausea, weight loss
Venlafaxine Effexor Hyperactivity and inattention Yes Headache, nausea, dizziness, dry mouth
Fluoxetine Prozac Repetitive behaviors Yes Headache, dry mouth
Citalopram Celexa Repetitive behaviors Yes Elevated energy levels, hyperactivity, diarrhea, dry skin

Sleep Therapy Options

If the preliminary assessment indicates the presence of a sleep disorder in a child with ASD, then treatment will likely be the next step. Cognitive behavioral therapy (CBT) has proven fairly effective in alleviating sleep disorder symptoms for young people with ASD. CBT is designed to improve sleep hygiene in patients by educating them about the science sleep and helping them find ways to improve their nightly habits. A study published in the Journal of Pediatric Neuroscience noted that children with ASD are often set in their routines, so establishing a consistent bedtime schedule can be quite beneficial to them. A healthy bedtime schedule might consist of the following:

  • Putting on pajamas
  • Brushing teeth
  • Using the toilet
  • Washing hands
  • Getting in bed
  • Reading a book (or being read to)
  • Shutting off the light

Additional behavioral interventions may help children with ASD improve their difficulties with sleep. According to a ‘Sleep Tool Kit‘ published by the Autism Treatment Network, these interventions include the following:

  • Create a ‘visual schedule checklist’ with pictures, objects and other visual aids that can help a child with ASD grasp the concepts more easily.
  • Keep the bedtime routine concise, and limit it to roughly 30 minutes before bed. Otherwise the child might become overwhelmed with too many commitments.
  • Order the routine so that stimulating activities like television and video games come first, followed by reading and other relaxing activities.
  • Physically guide the child to the schedule at first, and use verbal cues to remind them to check the schedule. Teach them how to cross things off on the checklist themselves.
  • Provide positive reinforcement whenever the child follows the schedule correctly.
  • If the routine must be changed, let the child know in advance so that they can mentally prepare for the disruption. Alter the checklist ahead of time to reflect these changes.

In addition to CBT, light therapy (also known as phototherapy) may also help children with ASD sleep better. This form of therapy is usually conducted using a light-transmitting box kept near the child’s bed. By exposing the child to bright light early in the morning, this therapy can help boost melatonin production and make children feel more alert throughout the day.

Pharmacological Treatments

Therapy interventions are often effective, but some children may not respond as well to them. If this is the case, then parents may want to consider some sort of pharmacological treatment. In lieu of prescription pills, the two options below are considered the most suitable route for children with ASD — though parents should not give either of these to their child before consulting a physician:

  • Melatonin: As mentioned above, children with ASD often experience circadian rhythm disruption that can lead to low melatonin levels. Melatonin supplements are widely available over-the-counter, and can help boost deficient melatonin levels. They also carry a low dependency risk and few adverse side effects, though nausea, diarrhea, and dizziness may occur.
  • Dietary supplements: In addition to melatonin, other natural supplements can help induce sleepiness and improve sleep maintenance in children with ASD. These include iron, kava, valerian root, and 5-Hydroxytryptophan (5-HTP). Multivitamins may also help, as well. These supplements carry no dependency risk, and adverse side effects are minimal.

The Center for Autism and Related Disorders notes that parents should avoid giving certain over-the-counter medications to children with ASD, including sleep-inducing antihistamines like Benadryl that are often erroneously used as sleep aids.

Finally, if none of these sleep improvement strategies work, then parents may want to consider prescription medication. Rather than turning to z-drugs or benzodiazepines — which are primarily intended for adult consumption — children with ASD may respond well to these two prescription drugs.

  • Clonidine: Clonidine is an anti-hypertensive medication used to treat a wide range of conditions, including tic disorders and ADHD, both of which are commonly found in children with ASD. Clonidine also induces sleepiness, so it may be used as a sleep aid — though the drug carries a dependency risk. A 2008 study noted that Clonidine reduced sleep latency and nighttime awakening episodes in children with ASD.
  • Mirtazapine: Designed to reduce ASD-related anxiety, Mirtazapine has also been shown to alleviate insomnia symptoms in children and young adults between 4 and 24 years of age. However, antidepressants like Mirtazapine have also been linked to suicidal thoughts and behaviors in young people (adolescents in particular), so this medication may not be suitable for certain patients.

Treating Sleep Problems in Adults with ASD

Z-drugs, benzodiazepines, and other stronger prescription sleep pills may be suitable for some adults with ASD who are experiencing insomnia and other sleep disorder symptoms. However, adults are also encouraged to seek out cognitive behavioral therapy options and over-the-counter supplements like melatonin before resorting to prescription drugs. Adults with ASD should meet with their physician to discuss which treatment pathway is best for them.

Sleep Management Tips for People with ASD

Therapy and prescription medication can be an effective way to reduce problems associated with sleep disorders and disturbances. However, people with ASD may also experience improvements by simply establishing a healthy nighttime routine and improving their sleep hygiene.

Tips for Adults

Strategies adults can use to minimize sleep issues and get a good night’s sleep on a regular basis include:

  • Create a relaxing bedroom environment that is conducive to sleep. Beds should only be used for sleep and sex, so refrain from activities like eating, watching television, and reading in bed; confining these activities to other areas of the house will help establish a more sleep-friendly atmosphere in the bedroom.
  • Eat balanced dinners and snacks prior to bedtime, and avoid substances like alcohol, nicotine, caffeine, and sugar as much as possible.
  • Electronic devices like TVs, computers, tablets, and smartphones emit ‘blue light’ that can hinder melatonin production and increase sleep latency. Recent studies suggest that people should avoid all electronics for at least one hour before bedtime.
  • Avoid napping for more than thirty minutes during the day, and less than three hours before bedtime.
  • Fluorescent and LED lights also emit blue light, as well as ‘artificial light’, which can also cut down on melatonin production. Outside lights may affect sleep onset and maintenance, as well. For optimal bedroom conditions, consider installing adjustable lights that can be dimmed; this will help boost melatonin production. Also make sure the curtains are drawn in order to block outside lights, as well as daylight when morning arrives.
  • Make sure the bedroom is temperature-controlled, and that the thermostat is set to a comfortable level. Don’t be afraid to adjust the temperature to correspond with seasonal changes.
  • If nightly discomfort is an issue, then it might be time to replace the mattress. Most mattresses need to be tossed out after seven years of consistent use. Sleep position may also be a factor, since people who sleep on their sides and backs tend to be more comfortable on mattresses made of memory foam or latex, which are designed to conform to the contours of the human body and provide spinal support. Innerspring mattresses, by comparison, offer little spinal support or contouring, and are less suitable for most side- and back-sleepers.
  • Keep a sleep diary. This will help track nightly patterns and changes, and can be a useful reference for physicians. Sleep diaries are often required as part of CBT and light therapy.

Tips for Children and Parents

Parents of children who have been diagnosed with ASD and are experiencing sleep problems can also use the strategies listed above to help their kids get enough rest each night. The established bedtime routine schedule discussed in the previous section can also be useful. Additionally, here are a few more tips for parents of sleep-deprived kids with ASD.

  • Many foods naturally induce sleep, and parents can include these in nightly meals and snacks to help their kids rest better. These include nuts, leafy greens, dairy products, and other products that are rich in calcium and magnesium. Tryptophan can also induce sleepiness; this amino acid is found in turkey, chicken, bananas, and beans. For children with low melatonin production, try fruits like sour cherries, grapes, and pineapple that contain high levels of natural melatonin.
  • Daytime exercise can help children feel more naturally tired at night, while physical exertion too close to bedtime can actually hinder sleep. Encourage children with ASD to get exercise during the day, but try to curtail these activities in the hours leading up to bed.
  • Relaxation techniques often do wonders for children with ASD who are experiencing sleep troubles. These include meditation, listening to soft music, reading, or simply laying in bed with the lights off. Parents can also participate in these activities to guide the child along and make sure the techniques are working effectively.
  • Sensory distractions are a major issue for children with ASD at all times of the day, particularly at night. To help them sleep better, test the floor and door hinges for creaking sounds. Other sensory considerations include outside light, room temperature, and bed size.
  • If the child follows an established bedtime schedule, be sure to check on them during the early stages to ensure they are actually asleep when they are supposed to be. If they are awake and seem distressed or upset about not being able to fall asleep, take a minute to reassure them that everything is all right. Many children with ASD respond well to physical touching, so also try patting them on the head, rubbing their shoulders, or giving them a high-five to help ease their worries.
