Autism and Sleep Issues: A Complete Guide for Better Sleep

Are sleep issues disrupting your nights? Everyone needs good sleep to manage emotions, stay healthy and learn well. But quality sleep doesn’t come easily to everyone, and it’s often harder for autistic people, who are more likely to have trouble falling asleep, staying asleep, or both. Many parents of autistic children know this all too well.

Let’s look at the connection between autism and sleep issues in more detail, and what can help, whether you’re an autistic adult or the parent of an autistic child.

Autism and Sleep Issues: What Are the Signs?

Here are some signs that you, or your child, may be having sleep problems:

1. Struggling to Fall Asleep

Taking a long time to fall asleep is one of the most common signs that something is affecting sleep. Many autistic people are highly attuned to their surroundings, so small things like a noise, a light or the feel of the sheets can make it hard to drift off.

2. Waking Frequently During the Night

Some people can fall asleep but can’t stay asleep. Waking often during the night can point to an underlying sleep issue, sometimes linked to a change in the body’s sleep-wake cycle.

3. Waking Up Worn Out

Waking up tired, even after enough hours in bed, is another sign of sleep issues. It can happen when sleep is disrupted and you don’t get enough of the deeper sleep stages you need to feel refreshed.

4. Feeling Sleepy During the Day

Feeling drowsy at work, school or home during the day is a clear sign of sleep issues. In children, tiredness doesn’t always look sleepy. It can show up as more meltdowns, less patience, or finding it harder to focus. Take daytime tiredness as a reminder to look at what’s happening at night.

Types of Sleep Disorders in Autistic People

Common sleep issues that affect autistic people include, but are not limited to, the following.

1. Insomnia

This is one of the most frequently reported sleep challenges. A person might lie awake for hours, or wake up several times during the night and have trouble getting back to sleep.

Insomnia may be caused by:

• Anxiety
• Sensory differences
• An irregular sleep-wake cycle

Insomnia has a ripple effect on mood, focus and overall wellbeing. When it goes on for a long time, it can lead to:

• Increased anxiety
• Shorter attention span
• Physical health issues

So it’s worth working out what’s causing the insomnia and then addressing it. Solutions may include:

• A calming bedtime routine
• Weighted blankets
• Guidance from a sleep specialist

2. Hypersomnia

Hypersomnia is in some ways the opposite of insomnia: people with it sleep a lot but still wake up tired. This affects energy levels and focus during the day.

Hypersomnia can be linked to mental health conditions, neurological conditions and other medical causes. If you or your child has it, seek professional help, because without support it can lead to:

• Emotional distress
• Pulling back from social activities
• Safety risks

3. Delayed Sleep Phase Syndrome

To sleep well, the body’s internal clock needs to be in sync with the world around you. When the body clock runs late, it can clash with school, work and family schedules.

Unlike people with insomnia, people with delayed sleep phase syndrome (DSPS) can sleep well if they are allowed to follow their natural rhythm. Trying to force an earlier bedtime often leads to frustration. DSPS is common in teenagers and young adults and is often linked to genetic factors.

4. Sleep Apnea

Sleep apnea causes a person to stop breathing for short periods during sleep. These pauses can last from a few seconds to a minute or more. They may be due to low muscle tone or enlarged tonsils and adenoids, but sometimes the cause is hard to pinpoint. Snoring, gasping or restless sleep are signs to mention to your doctor.

The three types of sleep apnea are:

• Obstructive sleep apnea (caused by a physical blockage of the airway)
• Central sleep apnea (when the brain doesn’t send the right signals to the breathing muscles)
• Complex sleep apnea (a combination of the other two)

5. Night Terrors

Night terrors are different from nightmares. A person may suddenly sit up, scream or thrash about while still mostly asleep, and can be hard to comfort. Unlike nightmares, they usually have no memory of it the next morning. Night terrors are more common in children and can be very distressing for parents to watch. Stay close, keep your child safe and wait for it to pass.

6. Sleepwalking

People who sleepwalk might walk, talk or even do simple tasks while still asleep. Sleepwalking disrupts the sleep cycle and raises safety concerns, so lock outside doors, secure windows and stairs, and try to understand the triggers to manage it better.

How Sleep Issues are Diagnosed in Autistic Individuals

The process begins with a medical history. Doctors will ask about:

• Sleep patterns
• Bedtime routines
• Anything else that seems to be keeping you or your child awake at night

The aim is to help the doctor understand what happens at home during the night. They may also use:

1. Sleep Diaries

You or a caregiver record sleep patterns over a few weeks, including when sleep starts, night wakings and wake-up times. The diary helps doctors spot patterns.

2. Sleep Study

Sometimes a doctor may suggest a sleep study. You (or your child, with a parent) spend a night at a clinic or hospital while staff monitor:

• Brain activity
• Breathing, among other things

Let the sleep clinic know about any sensory needs beforehand, as the sensors and new surroundings can be a lot to cope with.

3. Actigraphy Watches

These are wearable devices that track sleep-wake cycles. They provide useful data over several days and nights, which helps doctors understand the sleep challenges you are facing.

What Causes Sleep Issues in Autism?

Does autism cause sleep issues? Not directly, but sleep problems are much more common in autistic children than in non-autistic children, with studies suggesting that roughly half to four in five are affected. Sensory differences, anxiety, body clock differences and co-occurring conditions all play a part (our guide to sleep problems in children with autism or ADHD looks at the overlap). Here are some of the common reasons autistic people may not sleep well:

1. Sensory Processing Differences

Many autistic people are more sensitive to lights, sounds or textures. If these are present at bedtime, it’s much harder to settle. Even a slight noise or a flicker of light can be enough to cause discomfort.

2. High Energy Levels

Some people with autism have high energy levels, even late in the evening, which can make it hard to wind down at bedtime. A calm environment and a predictable wind-down routine can help the body get ready for sleep.

3. Big Emotions

Strong emotions, whether excitement, worry or frustration, can affect sleep. Some people find it hard to unwind after an exciting or stressful day, and those feelings can keep them awake past bedtime.

4. Anxiety

Many autistic people experience anxiety, often linked to social demands, change or sensory overload. When the brain stays in overdrive, it takes longer to switch off at night.

5. Medication Side Effects

There is no medication that works as an autism treatment in itself, but some medicines prescribed to autistic people for co-occurring conditions can affect sleep. Stimulants, which are commonly used to help with ADHD, are a good example. They can help with focus during the day but may make it harder to fall asleep at night. Talk to your doctor if you notice this, and read more about ADHD and sleep if your child has both diagnoses.

How Can You Improve Sleep in Autism?

Here are practical steps that can help improve sleep, for autistic adults and children:

1. Create a Comfortable Sleep Environment

A good sleep space is:

• Calm
• Dark
• Quiet

Blackout curtains help keep the room dark, and a white noise machine can mask sudden sounds. Think about the temperature, the feel of the bedding and pajamas, and any lights from devices.

2. Set a Consistent Sleep Routine

Going to bed and waking up at the same times each day makes a big difference to sleep quality. Build in the same relaxing activities before bed each night, like a bath, a story or quiet music. A visual bedtime routine, with pictures for each step, can help children know what’s coming next. Steps like brushing teeth and changing into pajamas also build the self-care skills covered in our parent guide to life skills. For a step-by-step plan, see our guide on how to help your autistic child sleep better.

3. Limit Screen Time Before Bed

Screens can make it harder to wind down. Try switching off phones, tablets and the TV about an hour before sleep, and swap in a book, a puzzle or quiet play. A visual timer can make the switch-off easier.

4. Keep Stimulants to a Minimum

Caffeine (including in cola and chocolate) and lots of sugar can affect sleep, so it’s best to have them earlier in the day, if at all. Try something soothing in the evening instead.

5. Pay Attention to Diet

Evening meals and snacks can affect sleep. Avoid heavy or spicy meals close to bedtime. A light snack, like a banana, yogurt or a warm glass of milk, can be a good alternative.

6. Address Sensory Needs

Many autistic people have specific sensory preferences that affect sleep. Try different tools to see what feels comforting, such as a weighted blanket, a soft nightlight, a favorite soft toy or snug bedding. Let your child help choose.

7. Get Movement and Daylight During the Day

Time outdoors in daylight, especially in the morning, and plenty of active play during the day help set the body clock and make it easier to feel sleepy at night.

8. Consult a Healthcare Professional

Sometimes sleep challenges need extra support. A GP, pediatrician or sleep specialist can look for underlying causes, such as sleep apnea, reflux or anxiety, and suggest solutions. For some autistic children, a doctor may discuss medication such as melatonin alongside routine and environment changes.

Tips for Parents of Autistic Children

• Look for the message. Night waking or bedtime distress is often communicating something, like discomfort, anxiety, hunger or sensory overload. Ask “what is this telling me?”
• Make bedtime predictable. Use the same steps in the same order, and give warnings before bedtime starts.
• Keep night wakings calm and boring. Low light, few words and the same response each time.
• Look after yourself. Broken sleep is exhausting. Share night duties if you can, and ask for help. Your sleep matters too.

Autism and Sleep Issues in Toddlers

Sleep issues often show up early. Autistic toddlers may take a long time to settle, wake for long stretches at night or wake very early. Keep naps and bedtime consistent, use a simple picture routine, dim lights and switch off screens an hour before bed, and talk to your child health nurse or GP if sleep is affecting the whole family.
