Weighted Blankets for Autism – What Are the Benefits?

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects a person's social interaction, communication, and behavior. It can also result in sleep disorders, anxiety, and other sensory processing issues. One of the ways that people with autism can find relief is through the use of a weighted blanket.

What are Weighted Blankets?

Weighted blankets are blankets that are filled with materials such as plastic pellets or glass beads to add weight to the blanket. They are designed to provide a deep pressure touch that many people find calming and soothing.

Benefits of Weighted Blankets for Autism

Research has shown that weighted blankets can provide a number of benefits for people with autism.

Improved Sleep

Many people with autism struggle with sleep disorders, which can lead to a host of other issues. Weighted blankets have been shown to improve sleep and increase the amount of time spent in deep sleep. This can lead to improved mood, behavior, and overall health.

Reduced Anxiety

Anxiety is a common issue for people with autism. Weighted blankets have been shown to reduce anxiety by providing a sense of comfort and security. The deep pressure touch can help to calm the nervous system and reduce feelings of stress and anxiety.

Sensory Processing

Many people with autism struggle with sensory processing issues. Weighted blankets can provide sensory input that can be calming and soothing. The pressure from the blanket can help to regulate the sensory system and improve overall sensory processing.

The Science Behind Weighted Blankets

Weighted blankets work by applying deep pressure touch (DPT) to the body. DPT stimulates the release of serotonin, a neurotransmitter that regulates mood and behavior. Serotonin is converted into melatonin, which helps regulate sleep-wake cycles.

The weight from the blanket also activates the parasympathetic nervous system, which is responsible for calming the body down. This leads to a decrease in heart rate and blood pressure, as well as a reduction in cortisol levels.

In addition to these physiological effects, weighted blankets can also have psychological benefits. The feeling of being hugged or held can provide a sense of security and comfort, reducing feelings of anxiety and stress.

Research has shown that weighted blankets can be effective in improving sleep quality, reducing anxiety levels, and promoting relaxation. However, it's important to note that not all individuals may find weighted blankets helpful and more research is needed to fully understand their impact on different populations.

How to Choose a Weighted Blanket for Autism

When it comes to selecting a weighted blanket for someone with autism, there are several key factors to keep in mind. First and foremost, it's important to consider the weight of the blanket. Generally, experts recommend choosing a blanket that is between 10-15% of the individual's body weight. This can help provide the necessary deep pressure stimulation that can be so beneficial for individuals with autism.

In addition to weight, size is also an important consideration. Blankets that are too small may not provide adequate coverage, while blankets that are too large may be cumbersome and uncomfortable. It's important to choose a size that is appropriate for the individual in question.

Finally, fabric selection is critical. The fabric should be comfortable and soft, as well as durable enough to withstand regular use. Many people find that natural fibers such as cotton or bamboo are particularly well-suited to weighted blankets, as they are breathable and hypoallergenic.

By keeping these key factors in mind, you can help ensure that the weighted blanket you choose is the perfect fit for the person with autism in your life.

Tips for Selecting the Right Weighted Blanket

When it comes to selecting the right weighted blanket, there are a few things to keep in mind.

Consider Sensory Preferences

One of the most important things to consider when selecting a weighted blanket is sensory preferences. Some individuals with autism may prefer a heavier or lighter weight, or may have specific preferences when it comes to fabric texture and type. It's important to take these preferences into account when selecting a blanket.

Choose the Right Weight

As mentioned earlier, choosing the right weight is critical when it comes to providing the necessary deep pressure stimulation. However, it's important to note that this can vary from person to person. Some individuals may prefer a slightly heavier or lighter blanket than what is typically recommended based on body weight alone.

Think About Temperature Regulation

Weighted blankets can be quite warm, which may not be ideal for everyone. If temperature regulation is a concern, look for blankets that are made from breathable materials and/or have cooling properties.

Assess Durability

Weighted blankets can be an investment, so it's important to choose one that will stand up well over time. Look for blankets that are made from high-quality materials and have strong stitching and construction.

By keeping these tips in mind, you can help ensure that you select a weighted blanket that meets all of your needs and preferences.

Case Studies: How Weighted Blankets Have Helped Individuals with Autism

While research has shown the potential benefits of weighted blankets for individuals with autism, real-life case studies can provide even more insight into the effectiveness of this therapy. Here are a few examples of how weighted blankets have helped individuals with autism:

Case Study 1: John

John is a 10-year-old boy with autism who struggles with sleep. His parents tried everything from white noise machines to medication, but nothing seemed to work. After hearing about the potential benefits of weighted blankets, they decided to give it a try.

Within just a few nights of using the blanket, John's parents noticed a significant improvement in his sleep patterns. He was falling asleep faster and staying asleep longer, which led to improvements in his mood and behavior during the day.

Case Study 2: Sarah

Sarah is a 16-year-old girl with autism who experiences high levels of anxiety. She often feels overwhelmed by sensory input and has difficulty regulating her emotions. Her therapist recommended trying a weighted blanket as part of her treatment plan.

After using the blanket for several weeks, Sarah reported feeling calmer and more relaxed overall. She also noted that she was better able to tolerate sensory input without becoming overwhelmed or anxious.

Case Study 3: Alex

Alex is a 6-year-old boy with autism who struggles with self-regulation. He often becomes agitated or upset when he feels out of control or overstimulated. His occupational therapist suggested trying a weighted blanket as a way to help him feel more grounded and centered.

After using the blanket during therapy sessions, Alex's therapist noticed that he was better able to focus and engage in activities without becoming dysregulated. His parents also reported that he seemed calmer at home after using the blanket regularly.

These case studies demonstrate just how powerful weighted blankets can be for individuals with autism. While not everyone may experience such dramatic improvements, these examples provide hope and inspiration for those considering this therapy.

Drawbacks and How to Avoid Them

While weighted blankets can provide many benefits for individuals with autism, there are also some potential drawbacks to consider. Here are a few things to keep in mind:


Weighted blankets can be quite warm, which may not be ideal for everyone. This is especially true for individuals who tend to run hot or who live in warmer climates. To avoid overheating, look for blankets that are made from breathable materials such as cotton or bamboo, and consider using a lighter weight blanket.

Difficulty Moving

Because of their weight, some individuals may find it difficult to move around comfortably while using a weighted blanket. This can be especially problematic for children who need to shift positions frequently during the night.
