Many of you are using SweetBeat for one of its several useful functions (stress, heart rate variability [HRV] for training, food sensitivity testing, etc.). Many of you are using HeartMath technologies in conjunction with SweetBeat – which we fully support! The Sweetwater Health team and HeartMath are front leaders in the HRV movement and long-time partners.
emWave® technology is based on learning to change your heart rhythm pattern to create coherence; a scientifically measurable state characterized by increased order and harmony in our psychological and physiological processes.
“Personal coherence, also known as psychophysiological coherence, refers to the synchronization of our physical, mental and emotional systems. It can be measured by our heart-rhythm patterns: The more balanced and smooth they are, the more in sync, or coherent, we are. Stress levels recede, energy levels increase and our brain and what HeartMath calls the “heart brain” are working together. It is a state of optimal clarity, perception and performance.” – As defined in the HeartMath FAQs.
SweetBeat has three main components: HRV for Training, stress monitoring and food sensitivity testing. If your body goes into a state of coherence, it will have an effect on your stress monitoring.
Below are some tips on how to understand your SweetBeat numbers:
- There are industry standards for low frequency (LF) and high frequency (HF) ranges
– LF = 0.04hz – 0.15hz
– HF = 0.15hz – 0.4hz
- Coherence is associated with a “spike” at 0.1hz frequency (LF)
- The SweetBeat stress levels are associated with a high LF with respect to HF (high LF/HF ratio). Because coherence is associated with a high power spike at 0.1hz, which falls into the HRV definition of LF, coherence shows as high stress in SweetBeat.
Here is an example of a coherence spike at 0.1hz:
- Very high power in the LF range (0.04hz – 0.15hz; blue) and little to no power in the HF range (0.15hz – 0.4hz; red). This is coherent data represented in Kubios
This is what a SweetBeat “Heart Rate Graph” looks like during coherence:
