Sleep Issues

What are Sleep Issues?

  • Approximately two-thirds of children with ASD have chronic insomnia, which is 2-3x greater than children without ASD. Children with ASD and with sleep disturbances had lower performance in daily living skills, social cognition, social communication and intellectual development than ASD children without sleep disturbances.

  • Sleep is an essential function for humans in order to allow the body and brain time to heal and repair, increase our immune system, and prevent many chronic diseases.

  • Sleep problems in individuals with ASD have also been associated with poor social interaction, increased stereotypy, problems in communication, and worsening daytime behavior, as well as increasing parental stress levels [2-5]

  • Both gastrointestinal issues and sleep issues are common in ASD, and there is likely a connection. [10]

  • It was discovered that the circadian rhythm plays a very important role in sleep!

    • The circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours.

    • Nutrition + meal timing can also play into the regulation of the cycle and hormone regulation

    • Thought to be the cause of jetlag

    • Having a good morning and nighttime routine is a great way to regulate the circadian rhythm!

    • Abnormalities in the circadian rhythm are hypothesized to play a role in sleep issues with children with ASD [1]

 
 

Signs/Symptoms of Sleep Issues

  • Restless sleep

  • Tired during the day

  • Fatigued

  • Irritable

  • Poor focus

  • Mood changes

  • Worsening daytime behavior

  • Chronic sleep loss over time can cause other health issues. If your child exhibits the following symptoms, it may be worth considering if sleep is a contributing factor:

    • Weak immune system

    • Difficulty learning or focuses

    • Increased body weight

    • Increase risk for cardiovascular disease

    • Hormone dysregulation


Daily Sleep Needs:

  • 1-2 years: 11-14 hours, including naps

  • 3-5 years: 10-13 hours, including naps

  • 6-12 years: 9-12 hours

  • 13-18 years: 8-10 hours

  • 18-60 years: 7 or more hours

Underlying Causes for Sleep Issues

Sleep issues can be caused by many other underlying nutritional issues such as: [1]

  • Gastrointestinal issues

  • Respiratory disorders

    • Sleep-disordered breathing

    • Allergies & asthma

  • Neurological disorders

    • Epilepsy/seizures

    • Restless leg syndrome/abnormal movements

  • Skin and integumentary disorders

  • Nutrition

    • Hunger

    • Nutrient deficiency

    • ”Growing Pains”

  • Certain Medications

    • Talk with your doctor

Next Steps

Nutritional Considerations for Sleep Issues

  • Address any underlying gastrointestinal issues

  • Consider all underlying factors (see above section)

  • Dietary changes:

    • No caffeine intake after noon, or eliminate altogether

    • Evaluate how much sugar your child has before bed or at dinner each night

    • Aim for 3 consistent mealtimes each day

    • Avoid heavy meals or large snacks late at night

    • A light snack may help some children fall asleep more easily at night

  • Trial certain supplements

    • Certain supplements can help children wind down and/or promote neurotransmitter balance, such as:

    • Consider taking B vitamins in the morning to prevent any sleep disturbances

    • Be sure to supplement with iron, as iron deficiency is a common cause sleep issues If you ever believe a supplement is causing sleep issues, discontinue and add it back

Lifestyle Considerations for Sleep Issues

  • Possibly the most important factor is creating a consistent bedtime routine that you can stick to

    • First, choose a bedtime and a wake time and keep it as consistent as possible all days of the week

      • Even weekends!

    • Next, determine which events are calming and which are stimulating. Calming events should be used during bedtime, and stimulating events should be moved to an earlier time in the evening

      • For example, bathtime may be calming or stimulating. Depending on which it is for your child, timing it in the evening can be helpful for sleep

    • Create a bedtime routine that is done in the same order each night

      • Consider a visual schedule or “to-do list” to help remind them of each step

  • Bedtime routine ideas

    • Dim the lights and turn off all screens at least an hour before bed

    • Keep the bedroom quiet, dark, and cool.

    • Take a nightly Epsom salt bath

    • Trial essential oils (lavender, roman chamomile, valerian, and ylang ylang are all calming)

    • Give your child a sensory massage

    • Try a weighted blanket (should not be heavier than 10% of the child’s body weight + 1 lb)

    • Kid-friendly alarm clock

    • For children that take naps, wake your child by 4pm from afternoon naps

    • Try a white noise machine

  • Consider alternative therapies

    • Trial meditation (yes, kids can do this too!)

    • Cognitive behavioral therapy

      • This may help a child talk through patterns that are contributing to limited sleep

    • Yoga is a non-invasive and alternative therapy that brings change in both physiological and psychological level of an individual. [11]

  • Other ecological interventions:

    • Remove toys and TV from room

    • Cool, dark environment

    • Transition to own bedroom

    • Nightlight

    • Having a pillow wrapped with a familiar scent (such as mother's PJs) has helped some children

The Bottom Line

  • Start with tips that work well with your family’s lifestyle

  • Try one small change, and then slowly incorporate other changes

  • Be patient. It can take upwards of 2 weeks of persistence to see a change.

  • Stay consistent!

  • Every child is different. Finding what works for yours is key!

DISCLAIMER: Before starting any supplement or medication, always consult with your healthcare provider to ensure it is a good fit for your child. Dosage can vary based on age, weight, gender, and current diet.

 

Sleep Issues & Autism in the Research

Prevalence of Sleep Issues in ASD

  • Approximately two-thirds of children with ASD have chronic insomnia, which is two to three times greater than children without ASD [1]

  • Children with ASD are extremely vulnerable to sleep problems due to underlying biological and behavioral rhythms that predispose them to extrinsic and intrinsic stressors affecting sleep. [1]

  • Sleep problems are common in autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) [2]

Symptoms Associated with Sleep Issues

  • Sleep problems in individuals with ASD have also been associated with poor social interaction, increased stereotypy, problems in communication, and worsening daytime behavior, as well as increasing parental stress levels [2-5]

  • Sleep disturbances were associated with extra nutrient supply during lactation and feeding, and child's picky eating. Autistic children with GI or/and sleep problems may represent clinically relevant subtypes of ASD, for which targeted treatments may be needed. [4]

  • Current evidence supports the existence of associations between ASD to circadian dysregulation, behavior problems, increased inflammatory levels of cytokines, sleep disorders, as well as reduced circadian neuroendocrine responses. Indeed, major effects may be related to a low melatonin rhythm. We propose that maintaining the proper rhythm of the circadian timing system may be helpful to improve the health and to cope with several behavioral changes observed in ASD subjects.” [6]

Sensory Processing Issues + Sleep

  • Touch hypersensitivity exhibits the strongest relationship with sleep disturbances in children with ASD, and in one study single-handedly explained 24% of the variance in total sleep disturbance scores. [7]

  • Atypical sensory behaviors are important to consider in relation to sleep deficits in children. [8]

  • Children with ASD who have anxiety and sensory over-responsivity may be particularly predisposed to sleep problems. These findings suggest that some children with ASD and sleep disturbance may have difficulties with hyperarousal. [9]

Gastrointestinal Issues and Sleep

  • Children with ASD and GI symptoms have been found to have a higher prevalence of sleep disturbances compared with typically developing peers who do not have GI symptoms. [10]

Circadian Rhythm and Melatonin Abnormalities

  • One hypothesis for sleep issues in ASD are circadian-relevant gene anomalies resulting in biological and behavioral rhythm disturbances [1]

  • A delayed melatonin rhythm and low melatonin amplitude has been hypothesized to be associated with a hard time falling asleep and night waking in children with ASD [1]

  • Multiple investigators have identified lower levels of melatonin or a major metabolite of melatonin in either the urine, serum, or plasma of individuals with ASD [1]

    • Keep in mind some children with ASD do not respond to melatonin and some families find that melatonin loses its effectiveness over time.
