Changing Heart Rhythms — Changes Feelings

Science has now shown us that the rhythm of our heart beat affects how we think and feel.
Learn to shift your heart rhythm to increase your emotional composure and clear thinking.

Experience the Shift


Observe your heart rhythm (HRV) which reflects your level of inner balance and your emotional state.

Coherent Woman

Use scientifically validated HeartMath techniques to guide you to a state of higher Coherence.

Session Screen

Real-time Coherence feedback confirms when you've made the shift and trains you to sustain it.

Coherence is an optimal physiological state shown to prevent and reduce stress, increase resilience, and promote emotional wellbeing. Coherence is measured through Heart Rate Variability (HRV) – a unique window into the quality of communication between the heart and brain which directly impacts how we feel and perform.


Regular use has a ‘carryover effect’ that builds and sustains resilience, reducing stress and improving health.

HRV & Coherence

Using a pulse sensor plugged into your emWave2 collects pulse data and translates coherence information into light patterns and user–friendly graphics displayed on your computer screen. emWave2 helps you create a coherent state through coherence techniques, interactive exercises and games, building resilience, increasing energy, and promoting focus, mental clarity and emotional balance.

How does the ear sensor work?

The sensor uses a minute amount of infrared light to measure the speed of blood flow in the ear. The sensor sends this signal to the emWave2 unit where the inter-beat interval is calculated in milliseconds and then heart rate variability is plotted. The amount of infrared light used in the measuring process is extremely small, safe and completely undetectable.

For those having trouble getting in the "zone"

Reviewer: A customer from Philadelphia, PA

I think this device is pretty neat personally. I always had trouble finding and staying in the zone of coherence. A few days ago for whatever reason went to a place of giving myself self love. I got to coherence quickly and was able to stay there pretty well. When I think of it now, it makes perfect sense. Self love, not the beach with the sun on my face or any other happy place outside myself.

Helps fight-or-flight response

Reviewer: A customer from

There are plenty of reviews here that talk about the technical aspects of this product. While I might mention a few things, my main focus in this review will be about my personal experience with the Emwave2. I have PTSD and had been thinking about getting some type of home biofeedback for a while. I came across an article online in which a person dealing with PTSD/fight-or-flight found this particular device to be extremely helpful. The price was a little daunting for me, but I really needed some help "turning off" the hyper-sensitive fight-or-flight part of my brain, even if only for a little while. I have some experience with yoga breathing, and that helped me adapt to this little device pretty quickly. I like the Coherence Coach and a couple of the games. Having a visual to watch is more helpful than I expected--being able to "see" if I'm in the "zone" makes a difference. When I use this multiple times a day, I am a calmer, less anxious person. The days I get lazy and don't use it . . . I can tell the difference. The ear clip never worked for me, but I do very well with the thumb sensor. I like that the device is small and easy to take with me. I like that I can "reset" my brain in as little as 5 minutes during the day. I like the simplicity. Thanks to the reviewers who recommended getting the online manual--that definitely helped me the first time I used the Emwave2. For me, it has been worth the investment . . . and I'll admit that wasn't the result I had expected :-)

This product is state of the art for under $200

Reviewer: A customer from

This product is state of the art for under $200. I have tried other bio feedback devices and none compare.

The device itself monitors heart rates and rhythms and provides clear feedback with color and tone, and both volume and brightness are adjustable. It has a breathing coach and provides visual feedback on your progress during session. You are able to adjust your challenge level as you improve too. It is tracking every session for you.

If you install the software, the session details are available for you to assess your condition and track your progress. There is a visual coach for relaxation and a number of games.

In summary, the device and software will lower your heart rate over time, and train your nervous system to recover naturally and more efficiently to stress. I recommend it daily and before any stressful meetings, and after any stressful days, and an hour or so before sleeping. I actually put it in my hand while falling asleep and focus on getting in the zone, falling asleep quickly in the process (all a part of my plan). It automatically turns off after a few minutes after you let go. It is state of the art. The sensors are high tech.

A review talked about it possibly being a hoax. It is the real deal. I have tested it. You can see the difference in the heart response to laughing, to startles, and to relaxation.

It is the real deal. It works. You have to invest your time into it. You will not be relaxed overnight. You must persist, just like with physical exercise, to reap the benefits. With this regular mental exercise, you will feel happier, less stressed, and think more clearly over time, which results in greater overall health.

A serious tool for Stress and Anxiety

Reviewer: A customer from

This is an exceptionally fine and sensitive instrument which I have found invaluable in terms of learning how to reduce stress and anxiety.
Like anything else it takes practice, and it is in the practice that you begin to see results. I am told there is a very slight delayed reaction primarily due to how long it takes the emWave to recognize a change in your physiological state,rather than the time it takes for your thoughts to go throughout your physiology. It takes patience and is not a one time use to immediately see fabulous results. It is a training mechanism with wonderful feedback. I have had great results with continued use, in the sense that the carry over from my practice sessions begins to stay with me throughout the day. Despite the naysayers, who probably have not put in the sustained effort, I highly recommend this since it has helped me to sustain a more balanced emotional state during times of stress, which in turn has brought much more clarity to my decision making. If you have patience and truly wish to work with your stress obstacles, this is for you. For me it was worth it to put in the time to learn, rather than having anxiety rip my body apart.
