Harkla Weighted Blanket For Autism, Anxiety Or ADHD

Weighted blankets have been used for quite a while in the world of special needs and anxiety disorders. However, they are starting to become popular outside of those realms and more in a day-to-day stress and sleep aid. 

When looking for solutions to normal stress and struggle sleeping, more people are turning to weighted blankets for help. The added weight of the blankets helps release the chemical serotonin in the body, which helps create a feeling of calm and relaxation. On top of that, serotonin is necessary for the body to make melatonin, which is a chemical which helps regulate the body’s sleep schedule. 

The science behind why weighted blankets work is called Deep Touch Pressure (DTP). DTP has been studied in various ways, including weighted blankets, weighted vests, and even massages. Anything that gives a gentle pressure on the body without hurting can fall under DTP. 

If you think a weighted blanket could help you or someone you love, then you’ll enjoy the infographic below. It covers more about why weighted blankets work, what to expect when purchasing one, and who to choose the right one.

Deep Touch Pressure (DTP)

Deep Touch Pressure is gentle pressure evenly distributed on the body. It can be accomplished by:

  • Hugs
  • Massages
  • Weighted Compression Vests
  • Weighted Blankets

What does Deep Touch Pressure do?

1. Increases the release of Serotonin: Serotonin is a chemical in the body that plays a key role in:

  • Sensory Gating and Processing
  • Behavior Inhibition
  • Appetite
  • Aggression
  • Sleep
  • Mood
  • Brain Development

Serotonin is also a necessary building block for melatonin. Melatonin is important for healthy sleep.

2. Reduces Nervous System Activity

What Are The Benefits of Weighted Blankets?

There are three major benefits of weighted blankets:

1. Reduces Anxiety: Whether it’s anxiety from autism, ADHD, PTSD, or an anxiety disorder.

2. Improves Sleep

  • Faster to fall asleep
  • Reduces anxiety
  • Deeper sleep
  • Less movement during the night

3. Improve Focus in Classroom

    • “ADHD improved 18 to 25% with on-task behavior while utilizing Deep Touch Pressure.”
    • Occupational therapists see the most improvement from deep touch pressure when it comes to staying on task, staying in seat and attention span.


How to Choose the Right Weighted Blanket for Yourself

To get the full benefits of a weighted blanket, it’s important to select a blanket that has the right amount of weight for you.

General Rule of Thumb: 10% of your bodyweight + 1-2 lbs

For example: A child that weights 50 lbs would be best suited with a 6-7 lb weighted blanket.
