The Science Behind Inner Balance

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.

Changing Heart Rhythms — Changes Feelings

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.

Jack Canfield
I, my staff, and my family use the Inner Balance. Many people do not know how to intentionally create the emotional states they want. The Inner Balance Trainer is ideal for easily and effortlessly accomplishing this.

Wendy Warner
In my practice, many patients have been meditating for years but still have abnormal nervous system and adrenal function. Once they add in the Inner Balance technology with coherence techniques, things shift. Coherence practice makes meditation easier. The heart rhythm feedback helps people be more efficient; even I will find myself drifting unless I'm monitoring my heart rhythms!

Inner Balance Bluetooth uses BT4.0 (BLE–Bluetooth Low Energy) which works at an output power range of 0.5 milliwatts (mW) or less — this is significantly lower than mobile phones which typically have output levels between 250 mW and 2000 mW. The tiny Bluetooth emitter is in the module that attaches to your garment, not in the ear sensor. Inner Balance Bluetooth is compliant with applicable FCC tests.
