Holosync Side Effects

While there are many positive user reviews on this product, there is still a number of folks that have reported dangerous side effects with this product. Some of the dangerous side effects found were:

• Short sharp pinches in the middle section of the headbill harris holosync review side effects

• Occasional memory loss

• The restless leg syndrome, if you have had a brain resection (also called temporal lobe resection) for removing focus for seizures.

Other peope who have used it for about 3 months complained of dizziness, lack of concentration and focus, being short tempered, anxiety, lack of motivation, feeling distant and disconnected from the world, huge cravings, lack of libido, panicking and disturbing sleeping patterns.

Although not all people have showed this side effects, this is something you want to be careful of.

My #1 recommendation for brainwave entrainment program for meditation, which you should consider using in place for Holosync, to avoid the side effects, is zen 12 Meditation program.

It is the safest (with no side effects), the cheapest, most convenient in terms of styles of meditation, well regulated for beginners, premium and advanced meditators, and pretty deep in terms of quality. It is actually way better than holosync in terms of calming effects and peacefulness.

What is Holosync?

Also called the awakening prologue, this is a program meant to use audio technology to help you, as the person meditating, to achieve deeper states of meditation and get quicker benefits that this practice brings. The website claims that you will be meditating like a zen monk, or more, just at the touch of the program’s button.

holosync reviews

What this program does is to boost the neuro electrical activities in both hemispheres of your brain at the same time, and cause your brain to get into the intense states of meditation in good time.

To me, this is advanced brainwave entrainment that will get the beginner’s mind a bit over stretched. It can only be helpful to people who are experienced in meditation. And I guess this is what makes for the side effects. The program does a lot of good to people who have been meditating for a while, but can be dangerous for beginners and early intermediates since it will be going a little too fast for their minds to hold.

It was made by Bill Harris who owns Centerpointe Research Institute, and his partner Wes Wait. According to the about page, it was built with the main aim of helping people get the benefits of traditional meditation while putting less time and effort into the practice. Ideally, it was meant for people living on tight schedules and others who want to meditate.

How Holosync Works

Holosync uses brain waves to bring about the meditative state of the mind you need when you want to meditate or feel relaxed and focused. This is known as brainwave entrainment.

It is where brain waves are monitored when functioning in different states, and then they are captured using advanced brain machines. The waves are then transfered into CD’s as audios.

holosync review - how it works

When you listen to the audios, your brain is able to detect the wave frequencies playing in your headphones, and it tries to copy them. As it does this, the state of your mind changes to the state that the frequencies of the waves in the headset are playing. For Holosync, the waves are for meditation, focus and relaxing, and others.

That is simply how you achieve the elevated station with this program.

To be more specific to Holosync, I found out that it uses 3 types of brain waves, the alpha, theta and delta brainwaves. It starts off high with the alpha, and then comes down to theta, and finally settles on delta where you get complete calmness, serenity and alertness.

How to Use Holosync

Well, you only have to take your pair of headphones and plug them in. Listen to the audios while meditating. In around 30 minutes, the activities of your thought will have ended and you will be able to get more from the session.

You are required to listen to these CDs for just 30 minutes. That should be enough to get the benefits you want.

My #1 Recommendation (Best alternative)

While Holosync program is great, effective and safe for advanced people who meditate and comes with many resources and options, remember the side effects you are exposed to by listening to it.

They may not have been seen in all beginners and intermediates, but you don’t how your particular body might react to it. And the price, for me, is a bit too high. Although, I have to say that it’s worth it based on the value you are getting off of them, and the flexible methods of payment given you.

But not all of us who are willing try out this program are able to part with such an amount. That is why I recommend a similar product called Zen 12, which is way cheaper, safer (no side effects at all) and much better than Holosync in quality, convenience and styles of entrainment.

It is also shorter in length, 12 minutes to be precise, and gives you the full benefits and value you get from 30 minutes worth of listening to Holosync, or perhaps more. I’ve tried it myself and really loved it. I was blown away by the way it starts, how it debelops through the session, and how it ends. It is so peaceful and profound.

  1. Thank you for your thorough review of Holosync.
    One of my cousins is currently using Holosync and she swears by it. I am curious about this program, although I’m not a strong advocate of meditation, being brought up with the notion that meditation can both be helpful and dangerous to the mind.
    I still have my doubts since I’m not sure how you can explain this scientifically. Is there some hypothesis at least to explain why some persons have such side effects? As for the Zen 12 program, is there no risk for a user to have similar side effects?

    1. Hey Princila,

      You are very right about meditation being both a great and dangerous tool at the same time.

      And the idea behind this notion is, it is good for your mind and spirit if you know how to work it out right. There are certain things, or criteria if you will, that you should follow as you meditate. They are based on certain principles that cooperate with the laws of thought and spirit.

      If you don’t get properly instructed on how to do your meditation the right way, you are bound to suffer the side effects of not keeping in line with the principles.

      But if you are sure to obey all of them, you are going to reap the refreshing benefits of it.

      Again, it depends on what kind of meditation you are doing. There are so many types out there. The Buddhist, Hindu, yoga, Christian and even Muslim meditation, which are all different and which give different results.

      You just have to know what you are on, and why.

      I hope I have put all your worries about meditation to rest.

      Now to zen 12, this is just a meditation aid that helps you reap more benefits of meditation by taking your mind into deep states of meditation that you see on experienced meditators.

      Without aids like these, it is very hard to ever get substantial amount of results within your first days, months or even years of mmeditating, based on your mind and other factors.

      But there are other aids like holosync that come with strong effects that some people’s minds can’t hold. I think they use advanced wave frequencies that alter the state of the mind in a huge way, more than the standard measure, that overpowers it, and thus cause the side effects.

      That is why I recommend using zen 12.

      Zen 12, specifically, doesn’t have any side effects. I did my research and didn’t see any complaint on it. I also use it and have found it to be great over the time I have been on it.

      Long story short, if you know the kind of meditation you are doing and how it should be properly done, zen 12 will help you get quicker calming effects and get the fruits of your effort within a short time.

  2. Rbtlrdoftkyo says:

    I had no idea stuff like this even existed. This was easy to read, and I’m glad I learned about this today! The Zen 12 sounds very interesting, and I’m definitely going to check it out. I think mediation is a wonderful practice for stress relief, especially with all the different inputs of information that we are exposed too today.

    1. That’s right Arol,

      Meditation sure is a great way to put off the tension.

      And zen 12 hastens the stress relief by hiking the state of your mind to enjoy these benefits much faster.

      Do check it out. You are going to love it. 🙂

  3. It’s a good thing that you have identified all of the negative effects of this program. I have always thought that audio meditation products such as this one, is completely harmless.

    But I’m guessing that most people are okay with this program and only a handful will experience the side effects? Or is this a program that every beginner should completely avoid?

    Great review!

    1. Hey Farhan,

      Holosync is a great program and there are many people who are getting pretty wonderful results with it. And based on my research, they are those who have meditated before.

      The thing is holosync brings side effects because they give deep waves in the beginning of the tracks which don’t start with where the average brain waves start from.

      That is why I say they are advanced, and newbies should try to avoid them. It is much safer and convenient to use zen 12 as a newbie because the wave frequencies used in it work best for starters, not to mention the guided meditation.

      In summary, holosync is great but I advise newbies not to get it as their first program.

      1. Tony Mueller says:

        I completed the whole holiday program ten years ago. I only have beneficial results and they are lasting.

        1. Hallo there Tony,

          Thanks for stopping by and for sharing our experiences with us.

          We appreciate your feedback.

          We are happy to hear you loved and benefitted from the program.

          We all have different results with a program since we all have different brain chemistry.

          And it is nice to hear it worked out for you.

  4. Hi Dave,
    So what does the zen 12 meditation program use differently that does not cause these symptoms?

    The look to me to be close to the same product. Zen 12 is quite a bit cheeper, so being a rookie at meditating I would go for the least expensive one.

    I personally feel that meditation is, removing yourself from all distractions and creating a peaceful state of mind. However, some people might need assistance to get to that state. That must be where zen 12 falls in to place.

    The side effects generated by the Holosync program is concerning though. Some sort of negative energy coming from it.

    1. Yeah Shaun,

      Although it works for the experienced meditators, it brings really bad energy for newbie meditators.

  5. Hi Dave,

    I have seen somethings kind of like this before that weren’t really focused on meditation and they recommend some different brands of headphones that transmitted the waves more clearly. Since Holosync is dependent on the waves created to changes the levels your brainwaves are on, do they recommend using a certain type of headphones?

    1. They sure do,

      Stereo headphones are the best. If you don’t have those, you can use earphones that have covered a huge part of your ears. You can also use ear buds.

  6. I have just purchased a program with an a.m. and a p.m. meditation, each lasting only 15 minutes. I have only used it once and it felt great. With such a short meditation, would the danger of negative side effects be less than for longer-lasting meditations?

    1. Hey Barb,

      The problem is not how long the program lasts, it is how it has been designed, the method of entrainment it uses.

      Something like holosync has used advanced brainwaves which may alter the brain a little too much and bring side effects to the listener. This doesn’t take into account how long the tracks take.

      As far as it uses those ueneven waves, it is still risky.

      The whole brainwave entrainment method of holosync is not good for everyone as each track, even the shortest ones have the advanced wave frequencies which pose the risk of getting the listed side effects.

      If I were you, I wouldn’t test the waters.

      It would be better to work with zen 12 as it is safe and good for everyone than to risk your health with the tracks you just bought.

      It is better to be safe than to be sorry.

      I hope this helps. 🙂

  7. Nice review mate. I used Holosync for a few months but I’ve experienced some of the side effects. I’ve had emotional numbness, and a general feeling of disconnection from everything. It made me way more calm, but not in a nice, present way. More of a lifeless way. It’s been a month since I’ve stopped and it’s gotten a decent amount better but it’s surprised me how long it’s taken! Any idea if my brain will return completely to normal or any clues on how to speed up the process? Thank you!

    1. Hey Joel,

      I am so sorry to hear the kind of side effects you are getting with holosync.

      You sure can get your brain back to normal.

      If you really want to know how you can get your brain back to the way it was, I would suggest you see a doctor because you never to what extent the advanced brainwave frequencies of holosync have affected you.

      They may be mild or serious. So I would rather you get medical attention than use other home remedies which may make the situation worse or try to treat something that isn’t there.

      Professional medication is the best.

      But for starters, you can try to avoid using the system completely.

      I hope to hear from you very soon mate.

      Please do let me know how things go for you.

    2. Hi Joel. I’m glad to find your posting, what I need to know. I started on a Holosync trial and I realised, of course, it’s hypnosis, which can be helpful if applied correctly. I had hypnotherapy for PTSD clinical treatment before. It worked in a bulldozing sort of way, so I felt empowered but at the same time, I could feel my ‘limbic’ or ‘reptilian’ emotions being suppressed. I stopped and switched to other more naturally paced method of recovery. The lifeless numbness you described sounds like dissociation, which in itself is generally not harmful but glad you know it’s not you. Since you have gotten better over time, it’s probably matter of time before the body-brain finds its own balance. I find bodywork (via conscious movement, touch, dance, etc) enhances connection back to the disconnected body. If it gets worse, I would see my GP for referral to a therapist.

      1. Hallo there Grace,

        Thanks for stopping by and for contributing to this topic.

        We appreciate your opinions and feedback.

        All the best.

  8. Hi, I’ve just purchased a program by Sonia Ricotti (the Unsinkable Bounce Back) and she uses two 12 min Holosync sessions (AM & PM) to boost up the brain vibrations to 500. One is supposed to use them for at least 21 days. Do you know anything about these custom-created sessions?

    1. Hey Carmen,

      I don’t know much about them, but I would advise you to be super careful as you plan to use them. They might be safe or dangerous.

      I recommend contacting the support team of the program to confirm of their safety and then get a few user reviews for the program to confirm if they will be good for you.

      Hope this helps. 🙂

  9. Very interesting posts here. While I wouldn’t call myself an advanced meditator, I am usually in a state of calm and being present most of the time, in other words, do not suffer at all from “monkey mind.” I just bought the sleep suite as I am a very light sleeper and get disturbed easily. I look forward to using it and then commenting as a review.

    1. Hey Pat,

      Nice to have you here.

      You must be quite a lucky person to have a calm and quiet mind yet you are not an advanced meditator. 🙂

      Most people are really struggling to get there.

      We are also sorry to hear you are struggling with sleep. We look forward to hearing your experience with the sleep suite.

      We can’t wait for your personal review of it.

      Have an awesome day! 🙂

  10. I have been using holosync for a couple of years and cannot really say anything bad about mine. no bad side effects. however when I bought a used one from amazon that was above the level that I was on there were some strange side effects. but they were not all bad side effects from that one some of the effects were good. a called holosync and they told me to throw that one out . I have no idea what affirmations that person had on theirs.

    1. Hi there Marianne,

      Thanks for stopping by and for your feedback on Holosync.

      Based on your story, we would conclude that there are other versions out there of the program that are counterfeit and dangerous.

      And people need to be wary of them.

      Thanks for that caution.

      Did the support team at Holosync tell you how to identify them?

      We look forward to your response.

  11. Anne Antonielli says:

    I am a Holosync user (Awakening Prologue, sublevel 3). In fairness to Holosync, there are 4 levels, and 4 sub levels within each level, therefore 12 levels. You haven’t mentioned any of that. Each of the levels take you a bit deeper so as to not overwhelm. They clearly instruct you on how to progress through each level to avoid being overwhelmed and encourage you to seek help from their support team when you do. If you go too quick through the program then may be this is why issues occur. One needs to get more information from the person experiencing the issues before stating that the program is dangerous – any program may be dangerous if you don’t follow the instructions.

    1. Hi there Ann,

      Thanks for stopping by and for sharing your thoughts and experience with Holosync.

      We really appreciate it. 🙂

      Thanks for pointing out why you feel the issue of feeling overwhelmed comes about with the program and offering solutions for that.

      It is educative and we are happy to get that information. 🙂

      You have enlightened us all in a great way.
