Is Anxiety Ruling Your Life?

We all experience stress. We may have an unusually difficult day or worry about a particular event. We feel anxious, yet we bounce back.

Many of us, however, carry anxiety with us everyday. Sometimes it's subtle but other times it is disruptive or even debilitating. Every time it's something we want to gain more control of. If you or your child experience any of following, the REI Custom Calm Program is made for you.

Anxiety Could Be Impacting Your Life if:

• You Worry All the Time.

• You Feel an Underlying Sense of Unease or Dread.

• You Avoid Certain Social Situations.

• You Have Panic Attacks.

• You Get Angry or Frustrated.

• You Feel Paralyzed by Fear or Uncertainty.

Anxiety Could be Impacting Your Child's Life if:

• Your Child Throws Tantrums.

• Your Child Becomes Unresponsive or Retreats into a Shell.

• Your Child Worries Excessively.

• Your Child Won't Let You Out of His Sight.

• Your Child Avoids or Wants to Avoid Certain Places or Situations.

Anxiety is Your Brain's Response to Danger and the Unknown

Anxiety is a primitive brain response to both uncertainty and danger. It is biological. It is our first instinct. And long ago, it was essential for our survival.

Our ancestors faced real threats everyday. Our brains developed to help us perceive these threats and respond appropriately. After all, our very survival was dependent on it.

Nowadays, many of us have a heightened fight or flight response. We respond to even minor threats or uncertainties as though we are in mortal danger. This suspends our ability to respond rationally. Instead, our primitive brain overrides our intellectual thought, flooding our bodies with chemicals (Adrenaline) to help us act and avoid, or remove, the threat. This is the fight or flight response.

Rarely are the things we get anxious over truly a threat to our survival; the chemicals our primitive brain releases into our bodies make us feel anxious. Anxiety is a physical response to our perception of danger.

Lower Your Anxiety by Changing Your Brain

Most anxiety reduction techniques offer stopgap strategies to help you cope until the Adrenalin is metabolized and your physical state returns to normal. The problem with this approach is that you are stuck in panic mode until the Adrenalin is out of your system. This takes time.

Some anxiety-reducing techniques teach you to prevent a fight or flight response. The problem with these techniques is that they require you to think when your brain wants to act. This takes a lot of work. 

There is a better way. Your your brain can learn how to release the chronic anxiety and respond to acute situations from a calm, resourceful place. The REI Custom Calm Program will teach your brain how to be calm.

Your REI Custom Calm Program Is Created Just For You

Whether you experience anxiety based-behaviors, tantrums, loss of sleep, panic attacks, social anxiety, or loss of concentration, we will create the optimal program to help you accomplish your goals.

We've Focused on Calm for Over 20 Years

Since our first clinical study in 1994, we have focused on how to reduce anxiety and induce calm. For ten years our research examined children and adults on the autism spectrum. This population proved to be an excellent anxiety-based arena for two reasons:

1. People with autism often have a lot of anxiety. And anxiety can rule much of their behavior. A child may tantrum when asked to enter a noisy, stimulating environment like a restaurant or shopping mall (or school lunchroom) or an adult may react aggressively when sharing mealtime with others.

Observing anxiety in people with autism is easy and noticing changes, however small, becomes simple. The cessation of crying in a tantrumming child or halting of aggressive behavior in an over-stimulated adult is an obvious measure of a reduction in anxiety.

2. Because autism is characterized by an inability to socially engage in an appropriate manner or an inability to communicate wants or needs, many people with autism have little to no awareness that some music (or other intervention) is going to be calming. And if they have such awareness, many have no idea how to self-regulate to calm on command.

This effectively removes the placebo effect. And because we are not using self-observed changes in anxiety, but instead use behavioral measures, we further remove any effects of the participants' expectation from the studies. Either a tantrum stopped or it didn't.

Our First Study Showed Significant Anxiety Reduction

Our first study was conducted in a public school setting with children between 6 and 12 years old. In this study we tracked immediate anxiety reducing effects as well as long-term changes in anxiety levels. In other words, we wanted to see if listening to REI Rhythms would reduce anxiety as it happened (ending a tantrum, for example) and whether any residual calming effect would result in changes of overall behavior.

Immediate calming effects were significant. Nearly all the participants were calmed most of the time.

The average frequency of time calmed by the recordings was 86.4%.

As far as overall changes in anxiety levels, we also saw significant changes as an average based on the pre and post tests. In the pre-test, average anxiety was listed at 82 on a 100 point scale. Anxiety on average after the study was reduced to 38 on a 100 point scale. This represents a significant reduction in anxiety over this 8-week period when the REI Rhythms were played quietly in the background.

Subsequent Studies Support These Results

Follow-up studies with autism as well as other conditions such as Anxiety Disorders, Attention Deficit Disorders, and Sleep Disorders, showed similar reductions in anxiety while listening to REI music.

For example, a study conducted in a residential facility for adults with severe autism showed significant changes in anxiety levels both facility-wide and in indivdual behavior.

One resident was extremely aggressive before the study began, often injuring other residents or the staff. Before the study, incidents were reported several times per week. Within two weeks of beginning using the REI recording, his aggressive outbursts virtually stopped. And they remained rare for the entire study period and extended follow-up of 6 months.

In another recent study, children within a public school showed significant reduction in anxiety-based behaviors while listening to REI rhythms. This study followed 10 students and showed reductions in behaviors in the following areas:

• Generalized anxiety

• Emotional outbursts

• Aggressive behaviors

• Self-stimulatory behaviors

• Sound sensitivity

As the study states: Anxiety reduction can take many forms, especially with the large variation of symptomatic behaviors and characteristics present in children on the autism spectrum.

What People Are Saying About Rhythmic Entrainment Intervention (REI)

John Doe UI/UX Designer

“She is much calmer after REI...”

“Our daughter has had very few temper tantrums. She is also developing the ability to stop herself and calm herself down, usually within about one minute of when the recording starts.

She’s been getting along much better with her brothers and sisters. Her attention span has increased--she can sit quietly and read a book for longer periods of time. She’s paying attention more in school and staying on task.”

Lisa D.
- Mother of an 8-year-old with ADD

“We turned on the music and he responded instantly...”

“When we had the CD made, we put it in while he was in a session with his craniosacral therapist. He responded instantly! His system was calming down, and to the surprise of his therapist, he started vocalizing. …

We went from nothing to something with vocalizing… He is now starting to put sentences together, and I’m very pleased.”

The REI Custom Calm Program Tackles Anxiety with a Two-fold Approach

Immediate Calm

Our first goal is to create an immediate sense of calm. We begin by injecting novelty to break the habitual anxiety response, followed by entraining the brain to a relaxed neurological state.

This stops a panic attack, a tantrum, an emotional outburst, or any of the fight or flight responses.

The more often you use the REI to stop a anxiety attack, the more easily – and quickly –your brain shifts to a calm state.

Long-term Change in Anxiety

Secondly, we teach your brain how to achieve a relaxed state on its own. We do this by providing progressive stimulation. Each of the weekly tracks in this 30-day program builds on the previous track and teaches your brain how to respond from a more resourceful space.

This means that you will no longer feel that sense of dread. Your brain will respond to the world from a relaxed state. and no longer automatically enter a primitive, adrenaline-infused, brain response.

Don't just take our word for it. Here are some real-life examples of anxiety reduction with REI.

Giselle Sees Big Changes in Social Anxiety and Fatigue

When Giselle began REI she was experiencing severe fatigue in the afternoons, which required her to go home from work at lunch to take nap in order to have the energy necessary to finish her day. As well, she described having feelings of anxiety for which she was seeing a therapist. She chose to try to REI Custom Program after using Calming Rhythms for her nap and noticing that she had more energy after listening to it.

After 1 1/2 weeks of using her REI Custom Program recording #1, she described that she had much more energy and didn’t feel the need to go home at lunch to take a nap. Instead she played her CD while she ate lunch. As well, so found that she spontaneously left her apartment one evening to go on a walk. Prior to this occasion she would need to get in her car from the basement garage and drive a few blocks in order to take a walk due to her anxiety over leaving the front door of her apartment building. She had been working on this issue in therapy for several years with no improvement until beginning the REI recordings.

After 8 weeks on REI, Giselle has much more energy and didn’t experience the afternoon fatigue that she had in the past. She also fond herself no longer having anxiety about leaving her apartment building on foot and took her daily walk without needing to drive her car from her building. She was continuing to listen daily to recording #2 during her lunch break.

Michael's Motor and Vocal Tics Stopped and His Anxiety Decreased

At the beginning of his REI Custom Program, Michael’s tics were present most of time, usually starting just an hour or so after waking in the morning and continuing until bedtime. His vocal tics included grunting and throat-clearing while his motor tics consisted of lip-smacking and picking, neck-rubbing, and finger-bending.

The degree and intensity of his tics seemed to be related to his anxiety and energy level. If he was tired, he exhibited more tics. Likewise, when he was anxious, his tics were more pronounced.

Michael also exhibited high levels of other anxieties. These centered around fear of new places, unexpected events, and separation from his parents. On a good day he was able to go to school without clinging and displayed only minor trepidation toward new or unexpected situations, such as an unscheduled trip to the store or an event outside his normal routine. His anxiety exhibited itself as clinginess, crying, and tic behavior, most notably vocal tics.

Early in his REI Program, Michael exhibited less anxiety over everyday changes, such as going to school or therapy sessions, where he is separated from his mom. His sleep also improved. His vocal tics were slightly less frequent, while his motor tics remained pretty much the same.

Midway into the program his parents noted that his motor tics remained somewhat variable, but their frequency overall was down from the beginning of the program. Stressful situations, as expected, increased his tic activity. Because his anxiety overall was lower than when he began the program, he seemed to be less bothered by situations that used to be stressful for him.

The vocal tics were essentially absent and there were longer periods of time with few, if any, motor tics. At one point during this period he caught a cold and his tics increased. They reduced again once his cold was over. This demonstrated more overall improvements but also suggested that stress on his system, both physically and psychologically, still had an impact on his tic behavior.

By the end of the REI program, Michael made significant gains in his sleep, anxiety, and tic behavior, with minor changes in some of his ADHD-type symptoms.

Kathleen Learned to Manage Anxious Thoughts and Began Sleeping Better

Before beginning the program Kathleen's sleep was poor. She would often fall sleep within an hour of going to bed but she generally woke several times a night and had trouble getting back to sleep because she worried about things. She also experienced anxious thoughts throughout the day. The worst times were when she drove in her car. This anxiety often resulted in her getting disoriented and feeling lost even when on familiar roads. She also wouldn’t travel on a plane. In addition Kathleen was disorganized and often missed appointments.

After about 3 weeks using the REI Custom Program, Kathleen began sleeping through the night. In the rare occasions where she did wake up at night, she found that she could turn REI recording #1 on and her anxious thoughts would quickly dissipate.

At the 8-week point of listening, she was consistently sleeping through the night with only the occasional night where she woke up. Again, turning on REI recording #1 would help her get back to sleep within 20 minutes (the length of the REI recording). She found that she was more energetic during the day and was more organized. She also began implementing an organizational system to help to keep on top of things. As a result she hadn’t missed any appointments in six weeks. Her anxiety during the day had reduced significantly - she was able to drive to and from work without getting anxious, though she still didn’t feel comfortable driving anywhere new.

After 16 weeks, Kathleen was still sleeping well - only woke occasionally at night but would be able to get back to sleep quickly by playing her REI recording. She continued to improve in her ability to manage her anxious thoughts. She took a plane to a conference for the first time.

After 5 years, she reported that her sleep was still good and her overall anxiety level was still very low even though she hadn’t heard her REI recording in three years.
