Sometimes, all we need is a little feedback to make positive changes within ourselves. Imagine if that feedback could come straight from your own heart. Well, now it can.

The award winning emWave2® is based on years of scientific research and is designed to teach you how to shift your emotional state in the moment – so you feel better and think more clearly.

When we’re stressed, we feel poorly, and our brain function and creative thinking become impaired.

We might overlook or forget important details, overreact to small stuff, say things we regret, get overwhelmed, have trouble sleeping or feel exhausted and drained. But it doesn’t have to be this way!

All Heartmath products come with a 2 Year International Warranty (outside USA).
    • With emWave2, you will learn how to restore emotional balance right in the moment you need it. Learn how to synchronize your heart, mind, and body to reset your composure and inner clarity, calm reactive emotions, and neutralize stress. This creates an inner state called coherence.

      With practice, you’ll feel calmer, more centered and focused – and enjoy a 'carryover effect' into your next activity. You will access more intuitive discernment to make better decisions.

      This self-empowering technology uses heart rhythm feedback to tell you when you’re on the right track. A quick and easy 3-5 minute session a few times a day is enough to make a meaningful difference.

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

    • The Science Behind emWave2

      The emWave2 analyzes our heart rhythm, measured by Heart Rate Variability (HRV), which indicates how emotional states are affecting our nervous system. HRV offers a unique window into the quality of communication between the heart and brain, which directly impacts how we feel and perform.

      Our heart rhythm patterns are the best reflection of our inner state. We can use the Inner Balance to see what's going on inside of us and learn how to shift into a state of balance, self-reliance and renewing feelings, such as appreciation and compassion.

      The Inner Balance trains us to self-generate a highly efficient physiological state called HRV coherence, which helps us increase emotional composure and clearer reasoning. Recommended by health professionals worldwide, a few minutes of daily coherence practice has been shown to reduce and prevent the negative effects of stress, such as overwhelm, fatigue and exhaustion, sleep disruption, anxiety and burnout.

    • No matter where you are in your journey, the emWave2® Trainer offers you the insight and awareness you need to jumpstart your transformation.

      Shift your emotional state in the moment and watch the changes occur in real-time.

      The emWave2 is optimized to ensure accurate HRV and Coherence measurement.

      How is the emWave2 different from a heart rate monitor?
      The emWave2 is very different from handheld devices that simply measure heart rate. The emWave2 analyzes your heart rhythms for “coherence”, a term used by scientists to describe a highly organized and efficient physiological state in which the nervous system, cardiovascular, hormonal and immune systems are working efficiently and harmoniously.A heart rate monitor only provides you with information about your average heart rate.

      How does using this stress management device differ from deep breathing?
      While rhythmic breathing exercises can help control your heart rate and have a calming effect on the body, shifting attitudes and emotions take more than that. Research shows that the key to learning how to neutralize and counter the effects of stress is by actively adding a positive feeling such as appreciation, care and compassion to the process. Experiencing positive emotions has a much broader range of health and wellness benefits than simply forcing the system into coherence through rhythmic breathing. Generating feelings of appreciation, care or compassion adds a dynamic element for stress management. Using the breathing pacer found in the emWave2 in conjunction with generating positive emotions helps synchronize your nervous system and creates positive changes in your heart rhythm patterns to create and sustain the coherence needed for stress relief.

      What are some of the benefits I could expect from using the emWave2 and how much time does it take to see results?
      Frequent users of the emWave2 
      • stress reduction
      • increased energy and resilience
      • greater mental clarity for decision-making and creativity
      • enhanced emotional balance and improved listening ability
      • better, more restful sleep

      Most people get into medium or high coherence within a few short sessions and feel a reduction in stress. Using the Quick Coherence® technique, which you can read about in the HeartMath Library or learn from the Coherence Coach® included in the Games section of the emWave program, is highly recommended as it accelerates the process of learning tools for stress management. Practicing stress management techniques is the key, but results generally come quickly. Additionally, emWave2 includes four challenge levels so that as you practice you can continue to refine your ability to eliminate and counter the negative effects of stress. Change to the next challenge level when you are consistently reaching 80-85% high coherence on a regular basis.

      How is the emWave different from other stress management devices?
      There are certainly other stress management devices designed to help people with stress and HeartMath's position is that we are very much in favor of any stress management devices or stress management techniques that can help with the mounting global stress problem.

      What distinguishes emWave from many other stress management products is the significant body of published scientific research that has been incorporated into its development. Our 20 years of experience, validation and practical applications demonstrate the effectiveness in all of the stress management products that HeartMath offers. Additionally, emWave2 is just one of many products found in the HeartMath system. The system — consists of tools, stress management techniques and proven computer based technology. All HeartMath products and services compliment each other and have been used for stress management and increasing performance by hundreds of thousands of people in over 100 countries, and applied in Fortune 100 corporations, health care systems, government agencies and school systems. emWave2 is an extension of this system and carries with it the breadth of scientific credibility and proven results associated with HeartMath.

      Has HeartMath done studies to support the benefits of the emWave?
      HeartMath has done numerous studies on the effect of positive emotions on stress, physiology and human performance. These studies have been published in prestigious journals including Stress Medicine, American Journal of Cardiology, Preventive Cardiology, Journal of the American College of Cardiology, Integrative Physiological and Behavioral Science and Harvard Business Review.

Awesome device - great complementation

Awesome device - great complementation to meditation for a calm mind and body. Doesn't seem to be much more than a breath-guiding device, but knowing the importance of the breath, it is understandable why it works so well!

Fantastic product

I started using the EmWave 2 when it arrived a fortnight and I’m amazed at how quickly I’ve managed to get into heart coherence even when I’m not using it.
