The Zoom device has been extensively tested to work with the SweetWater HRV family of apps.

What do I need to know?
The Zoom is a completely new user experience. Please read over this information before purchasing the device.

You must sit perfectly still while using the Zoom with our HRV applications. No talking, nodding, or any movement for the entire three minute session.

What’s new in SweetBeat HRV?IMG_1248 (002)

Checkup mode is a 3 minute countdown ideally suited for use with the Zoom device. Checkup can be run with any compatible BTLE heart rate monitor chest strap too. The three minute session allows the Zoom user to accurately assess stress and power levels.

Checkup mode is recommended for use during the day after the HRV for Training session has been run in the morning. Checkup can be run as frequently as needed to assess HRV and stress during daily activities. It can also used as a quick snapshot of HRV recovery during the day.

More to Come!
Our R&D team is working with LifeTrak to pull workout data, battery info and blue light exposure in SweetBeat! Stay tuned for updates to your SweetBeat app. Email us with questions or concerns: support@sweetwaterhrv.com.

 

New Graphs: SweetBeatLife Update!

Yes, you read it right! There is a SweetBeatLife update available, which includes brand new enhanced graphs. The graphs are completely interactive and allow for a better view of your SweetBeatLife metrics.

Key features of the new graphs:

  • Zoom in by putting your pointer finger and thumb on the graph and moving your fingers away from each other. Double tapping the graph can also be used to zoom in.
  • Zoom out by using the same two fingers and making a pinching motion.
  • By holding your finger down on the graph, you will create cross hairs to pinpoint.
  • There is a yellow circle with an “I” in the middle of it in the top right corner which opens up the graph’s key.
  • Turning your phone to the left will give you a landscape view.

Note: If you do not see these graphs when you open SweetBeatLife, this means you have to manually install the update. You can do this by going to your App store, click on the bottom right tab labeled Updates, and install the SweetBeatLife update.

Increase Your HRV, Lower Your Stress

You’ve just found the most powerful nervous system enhancement & stress relief tools in the world

Every person experiences stress from time to time.  Just the word may be enough to set your nerves on edge. Some, though, cope with stress more effectively, or recover from stressful events more quickly, than others. Some are chronically stressed and easily fall into coping strategies such as anxiety, anger, depression, overwhelm, sadness, overeating, and many others.

Effec­tive stress management and emo­tional reg­u­la­tion depends on your ability to flexibly adjust your phys­i­o­log­i­cal response to a chang­ing environment. This flexibility is also referred to as resilience and can be measured via Heart Rate Variability (HRV).

What does flexibility look like?

A flexible nervous system has a few components:

  • Balance between Sympathetic and Parasympathetic branches of the Autonomic Nervous System
  • The ability to carry a variety of electrical impulses throughout the body
    • Called power levels of the nervous system

SweetBeatLife measures these 2 branches of the Autonomic Nervous System via LF (Sympathetic/fight or flight) and HF (Parasympathetic/rest and digest). While a healthy balance of LF and HF power is a ratio of 1:1 to 2:1 respectively, many customers find that their LF response is consistently 5x, 10x, and even 20x greater than their HF response!

In addition, many people show LF power levels in the thousands while their HF power numbers are in the low hundreds. We even see LF readings in the hundreds and HF of less than 100. These low readings are indicative of chronic stress.

The Good News Is….

…you can re-wire your nervous system, increase your power numbers (and your resiliency) and measure your progress via HRV. How? By using Centerpointe Research Institute’s Holosync® audio technology in combination with the SweetWater Health iPhone app called SweetBeatLife.

Holosync® audio technology provides a super-enriched environment for your nervous system, causing enormous, beneficial changes in the brain. SweetBeatLife is the easiest and most accurate way to measure your HRV and track the changes in your nervous system as you progress through the Holosync® program.

By creating resilience via Holosync® meditation, people and situations that used to stress you no longer affect you the same way. Your nervous system becomes more balanced and resilient.

What is Holosync®?

Holosync® is an audio technology you listen to using stereo headphones, which enables the left and right brain hemispheres to be targeted separately. By gently altering the electrical patterns in your brain, Holosync® creates states pf profoundly deep meditation usually only experienced by advanced meditators meditating for several decades (e.g. Zen Buddhist Monks). Holosync® is based on research by Dr. Gerald Oster of Mt. Sinai Medical Center, a pioneer of the effects of binaural beats on the brain, and the world-famous Menninger Clinic.

Holosync® has been around for twenty-five years, and has been used by over two million people in 193 countries.

Most people know that an EEG measures the different frequencies of electrical brain activity. Alpha brain frequencies are associated with relaxation, focus and concentration and enhanced learning ability; theta frequencies with dreamless sleep, creativity, and visionary meditation experiences; and delta frequencies with deep sleep, access to the unconscious mind, and charisma and persuasiveness. It is believed that in these brain wave patterns, usually experienced during sleep, the nervous system and body repair and recover from the previous day’s stressors.

Research has shown that meditation alters the alpha, delta and theta EEG patterns significantly, thus aiding nervous system repair and recovery. Holosync®, by directing specific sound frequencies to each brain hemisphere, gently creates alpha, then theta, and delta brain patterns.

Your brain responds by creating new neural pathways linking the left and right hemispheres and similar links between the amygdala (the brain’s more primitive emotional center) and the pre-frontal cortex (the source of executive control). This enables the Holosync® user to mitigate emotional reactivity and self-sabotaging behaviors as well as experiencing the other benefits of deep meditation, but without the long learning curve.

HRV during Holosync Meditation

Below are some examples of HRV measurements during meditation using SweetBeatLife. While HRV is dynamic and not the same for everyone, there are average ranges for the general population. Image 1 (below) is from an individual meditating without Holosync®, and who has never used Holosync®. Notice the HRV maxed out at around 695. Image 2 is from an intermediate Holosync® user during Holosync® meditation. During this session the HRV was more than 5400 (higher HRV is a sign of higher nervous system flexibility). The advanced Holosync® user shown in Image 3 maxed out at 12,430 during a Holosync® meditation, clearly signifying a very high and healthy nervous system.

As you can see, the Holosync® users show a significant difference in HRV, a difference enabling them to navigate life’s challenges with more flow and happiness.

Visualizing HR, HRV, and GSR While Watching ‘Interstellar’ by Bob Troia

This blog repost is from one of our more “connected” users, Bob Troia, also known as Quantified Bob.  Bob enjoys tracking and analyzing his metrics based on the effects of many factors such as, his Bulletproof Diet, his glucose reading, even his personality type. To see exactly what Bob is tracking and read into his prior experiments go to his blog.

Interstellar

In this case, Quantified Bob took something as simple as watching the movie, Interstellar, and turned it into a Quantified Self experiment. He used a Polar H7 to capture 3-hours of biometrics, specifically RR-Intervals. The SweetBeatLife app then uses clinical grade algorithms to analyze the data. Anyone with one of our applications and a heart rate monitor chest strap (BTLE) can do the same. Bob exported his heart rate and heart rate variability data from SweetBeatLife, and his Galvanic Skin Response from a Basis B1. Read below to see his heart rate and heart rate variability response.

Heart Rate

“Interestingly, my heart rate trend (on the left, below) looks very similar to the original Reddit user (on the right)! Both of us are using data from our wrist-worn Basis devices – in my case, the older B1 model, and for the Reddit user the newer Basis Peak. Although the Peak is capable of capturing more samples, the data returned from Basis is always an average value for each minute.

Interstellar HR comparison

However, SweetBeatLife is recording data at a resolution of 1 sample per second via the Polar H7. The per-second pulse data is a little bit jumpy and hard to follow (in gray), so I’ll also include a 60-second moving average as well (in blue):

Interstellar Heart Rate Polar H7

It looks very similar to the data recorded by my Basis. Good!

Heart Rate Variability (HRV)

Heart Rate Variability uses a technique in which the spaces between heart beats are measured, and is a good way to measure stress via an individual’s “flight or fight” response (the higher one’s HRV, the better). There are a number of ways HRV can be calculated, and in this case we are using what’s known as rMSSD (root mean square of successive differences). You can check out Wikipedia for a pretty good overview of HRV.

Interstellar Heart Rate Variability

Not only can Bob see when the movie had him in sympathetic versus parasympathetic but he can point out when he was having deep thoughts of gravity and space. Bob was also able to determine that there is, “an inverse relationship between heart rate and HRV, which makes sense – if your heart starts beating faster, you are most likely encountering more stress, which increases your sympathetic response and thus lowers HRV.”

Read more about his Galvanic Skin Response and how Bob interpreted this data, read the original article here. If you want to better understand HRV and the many benefits of tracking it, I recommend browsing around the SweetWater Health Library.

Interview with Ronda Collier: How Heart Rate Variability Can Help You Manage Stress by Primal Blueprint

pb_podcast_banner_tE46

Description: Host Brad Kearns talks with Brock Armstrong (the voice of the MDA blog podcasts and a Sweetbeat ambassador/product tester) and Ronda Collier, CEO of Sweetwater Health, makers of the Sweetbeat Life iOS application. Sweetbeat Life allows for convenient Heart Rate Variability (HRV) measuring and information storage. This discussion will acquaint listeners with the basics of HRV, and proceed quickly to discuss some of the finer points of HRV’s effectiveness in monitoring stress and recovery. Heart Rate Variability is a measurement of the variation in intervals between heartbeats. More variation indicates better cardiovascular fitness and stress management, and is represented in a higher HRV number on a 1-100 scale.

Finer details of this show’s discussion include: how Low Frequency (LF) and High Frequency (HF) values correlate with sympathetic and parasympathetic nervous system activity; techniques for how to moderate your stress response and improve your recovery through breathing exercises, yoga, meditation, and extra sleep; and a step-by-step process for how to get started in HRV monitoring (buying the proper equipment, operating the Sweetbeat Life app smoothly, and understanding how to best use the informational graphs generated by the app). This is a fantastic show to help you jump head first into the amazing health technology of Heart Rate Variability!

The “Geek” Screen – Understanding the SweetBeatLife Metrics

Update: The HealthPatch is no longer available to consumers. We are disappointed by this news, but are continuing to search for consumer patch partners. This article has been edited to exclude the old HealthPatch metrics.

The new SweetBeatLife “stats” screen, more widely referred to as the “geek” screen, shows all the metrics used in the algorithm calculations. These are the metrics explained in order from top left to bottom right:

geekscreen2

Low Frequency (LF) – The low frequency metric shows the real-time power level of your sympathetic (fight or flight) nervous system in raw form.

High Frequency (LF) – The high frequency metric shows the real-time power level of your parasympathetic (rest and recover) nervous system in raw form.

LF/HF – Stress is associated with a high LF with respect to HF, or a high LF/HF ratio. By selecting the settings wheel in the top right corner, you can choose your “Stress Sensitivity Level”.

TIP: If you find that your stress level is always in the blue or the red, then you most likely need to change your “Stress Sensitivity Level”. If you are always in the blue, this means you need to base your stress level on a smaller ratio (high sensitivity level). Challenge yourself by moving up a level or two. If you are in the red, then you might need a higher ratio (lower sensitivity level). A good indication that your stress management techniques have worked is when you need to change your sensitivity level to a higher sensitivity level.

Root Mean Square of Successive Differences (rMSSD) – In other words, the square root of the mean of the sum of the squares of the successive differences between adjacent RR Intervals. I swear that’s in English. I suggest checking out our library and reading our HRV Measurements slides (slide 15) to thoroughly understand the different domains. The important thing to remember is thatrMSSD is a time domain standard and is just one of the several parameters that measure heart rate variability.HRVtrainingss

Heart Rate Variability (HRV) – HRV is the variation in the time interval between one heartbeat and the next. If only it were that simple; read our HRV backgrounder to learn more. In SweetBeatLife, HRV is a real-time scaled version (between 1-100) of rMSSD and represents the state of the autonomic nervous system and its ability to respond/react and recover from internal and external stressors. These stressors include orthostatic (standing and sitting), environmental and psychological.

TIP: The HRV for Training function of SweetBeatLife uses a special algorithm to customize your reference line and manage your training.

Heart Rate – Heart rate is the speed of the heartbeat, more specifically in this case, it is a real-time measure of your beats per minute.

*Respiration – Breathing correctly is an important factor in stress management and HRV for training. This is why we include a breath pacer. There are many different theories on which kind of breathing is best for your health. We use a specific pace meant to balance your nervous system.

TIP: The breath pacer featured on the relax screen within SweetBeatLife is proven to help balance the autonomic nervous system.

RR – On an EKG the heart rate is measured using the R wave to R wave interval (RR Interval). The RR metric is shown in real-time and quite necessary for the measurement of HRV.

TIP: Only heart rate monitors that are Bluetooth low energy (BTLE) and record RR Intervals can be used with SweetBeatLife for accuracy purposes. Pulse oximeters (watches, finger sensors, etc.) measure heart rate by pulse detection, which is not accurate enough for HRV. Please visit our compatibility chart for help and visit our health sensors page to purchase one.

 

*Steps – Another metric that may be familiar to you if you have ever used a fitness tracker. Your steps can be imported and tracker through your other wearables: Fitbit & Withings.
