The Science Behind Coherence

The Inner Balance technology analyzes and displays 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.

The Inner Balance technology 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, HRV coherence training has been associated with many health and performance benefits. 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.

HeartMath has been a pioneer in HRV research and self-regulation training for over 30 years. Over 250 independent peer-reviewed studies have been published on HeartMath technologies and methodologies.

Rated 5 out of 5 by from As an autistic adult, it helps me tremendously I love this tool to help me learn to calm diwn, and get more balanced in my day. I have neurological conditions too and it helps a lot there too. I use it in the morning and at night as part if my sleep hygiene. Also. When things get to be too much it helps ne calm my whole system. I love it!! I use the Inner-balance. The ear clip does not hurt and isn’t a physical issue for me.

Rated 2 out of 5 by from Works inconsistently My wife reports that her gift does not pick up the ear sensor reliably. She also found the app difficult to understand. Normally she's really good with tech.

Rated 4 out of 5 by from Love Using it for Breath work! My naturopathic doctor suggested I get this, and I do love using it. I've combined it with the breath work I was already doing and it's been great to track my HRV during my sessions. The user interface is pretty simple and has an older looking design, the reason why I gave it 4 stars not 5. But I like the screen options for following along and it was pretty easy to figure out. I do wish I didn't need to look at my phone so much while using it, but not sure how to avoid that unless there were more voice prompts to breathe in and out.

Rated 5 out of 5 by from Encouraging! Inner Balance has added to the benefits of Heartmath. I can now "see" my HRV while doing the practices. This will be a tremendous help in developing coherence. While I know I have achieved coherence because of the results; different practices have helped me lower my blood pressure and even lifted me out of a depression. Thank you Heartmath!

Rated 5 out of 5 by from Great tool to find stillness Package arrived quickly. Easy to follow-instructions. Extremely useful if you feel stressed or anxious and have forgotten what it feels like to be relaxed and calm. With this handy tool, you get instant feedback from your body, and you can't just pretend to relax. I have used it for 4-5 months now, and it's very inspiring to track my progression in the Inner Balance App. I have gone from almost not being able to stay in high coherence at all in Level 1 to being able to maintain high coherence in Level 3. Suffering from stress and muscle tensions for a long time and seldom being able to relax, it has helped my body to rediscover how it feels to be calm and relaxed. It has changed my life.
