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

2 Replies

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.

Why Artificial Sweeteners Make You Fat: What Do We Do Now?

1 Reply

SodaWe’ve been hearing for years that artificial sweeteners are bad for you and can actually cause weight gain. This flies in the face of logic. After all, if you’re consuming fewer calories than you would if you were using sugar or honey, how could they encourage weight gain? And just how bad are they for you in other ways? We decided to stop asking ourselves these questions and get down to what appears to be the truth of the matter.

Artificial sweeteners have been around for more than 130 years; saccharin was developed in 1878 from coal tar derivatives (yum!). It didn’t enter widespread use until WWI, due to sugar shortages. But artificial sweeteners experienced a huge boost in popularity in the 1960s and 1970s, as new sweeteners were introduced to satisfy the sweet tooth (teeth?) of dieters.[1] The rising tide of American obesity increased in step with the increase in consumption of artificially sweetened products, particularly diet sodas.

Artificial sweeteners have been controversial and subject to scrutiny almost from their inception. The USDA began investigating saccharin in 1907, and then proceeded to flipflop, proclaiming it an adulterant in 1911, then stating in 1912 that saccharin was not harmful to human health.

Cyclamates underwent similar scrutiny by the FDA in the 1960s, and is still banned in the U.S., spurring the development of alternatives such as aspartame and sucralose. Artificial sweeteners are in widespread use today in sodas, candies and other processed foods, as well as available on (almost) every restaurant table in America. Some, like stevia, claim to be derived from natural sources, the implication being that they are better for you than completely laboratory-derived products. (Most stevia products are actually highly processed.)

The basis for the story that artificial sweeteners promote weight gain comes from a study at Purdue University.[2] Rats were fed yogurt sweetened with glucose (table sugar) and compared to a group of rats fed yogurt sweetened with zero-calorie saccharin. Three different experiments were conducted to see whether saccharin changed the rats’ ability to regulate intake of calories. The saccharin-fed rats later consumed more calories, gained more weight, put on more body fat and didn’t make up for it by cutting back on calories. This phenomenon occurred at statistically significant levels.

The researchers postulated that when the body detects sweetness, it gears up to consume a high-calorie food. When the false sweetness is not followed by the anticipated calories, it confuses the body’s connection between sweetness and calories. This leads to increased intake of calories and a blunted satiety response to overeating, leading to increased accumulation of fat.

Of course, these were rats, not people. Other studies have shown that at some level, the brain can distinguish between real and artificial sweeteners—but not, as it happens, if the person regularly consumes diet soft drinks. A diet soda drinker’s pleasure center in the brain will respond equally to either sucrose- or artificially sweetened sodas. Activity was diminished in an area of the brain called the caudate head in diet soda drinkers. Decreased activation of this area is associated with elevated risk of obesity.[3]

So far, we’ve learned that artificial sweeteners may blunt people’s satiety response, but that if they come in the form of diet soda, this effect may be worsened. Is there anything else out there to worry us about artificial sweeteners?

Although there have been many hoaxes perpetuated around artificial sweeteners and their alleged danger to human health, according to the FDA, all sweeteners currently on the market have been conclusively proven safe for human consumption.[4] There is no credible evidence that any of these sweeteners cause toxic reactions, cancer, seizures, or any of the other claims that have been lodged against them.

However, there is ample evidence they can make you fat. What more do we need to know? Artificial sweeteners are products that do the exact opposite of what they were intended to do.

So what alternatives do we have? We know that sugar isn’t good for us, and we know that high fructose corn syrup is worse. Sugar alcohols (which are not alcohols) can raise blood glucose levels, although not usually to the level of sugar. Sugar alcohols (including maltitol, sorbitol and xylitol) can also cause gastric symptoms, especially in children.[5] Honey is no better than sugar, healthwise, especially if processed (raw honey may confer some health benefits in the form of trace minerals, vitamins and phytochemicals).

Fortunately, there are a number of alternatives for sweetening the morning cup of tea or coffee. Which you choose depends on your personal taste, plus where it falls on the glycemic index. Diabetics in particular need to find a low-glycemic-index sweetener they can live with if they wish to avoid artificial sweeteners.

Brown rice syrup. This has a distinct malty or nutty flavor. It falls high on the glycemic index at 85, which makes it unsuitable for diabetics. It does contain minute traces of arsenic because brown rice contains minute traces of arsenic, but not enough to harm you unless you’re really chugging the stuff—in which case, you might have other worries.

Coconut palm sugar. This is a pale brown, granulated sugar made from the sap of coconut palms. It has a pleasant, light flavor and is relatively low on the glycemic index at 35.

Barley malt syrup. This is derived from malted (sprouted) barley that is cooked until the starch converts to sugar. It comes as a syrup or powder and is 42 on the glycemic index.

Agave nectar. Made from the juice of the blue agave plant (the same plant used to make tequila). It’s low on the glycemic index, between 15 and 30, depending on whether you are using raw or refined syrup. The raw syrup is darker and has more flavor, while the refined is a light color and has less flavor.

Stevia. Stevia is 0 on the glycemic index although it is 200-300 times sweeter than table sugar. It is touted as a natural product, but the white powder you put in your iced tea is in fact the product of an intensive refining process (and may also contain maltodextrin, which is highly processed and may elevate blood sugar[6]). There are liquid tinctures of stevia available that are not highly processed.

The sweeteners mentioned here are widely available, affordable, and palatable to most people (although some people react strongly to the taste of stevia). Find out more about sweeteners and where they fall on the glycemic scale at http://www.organiclifestylemagazine.com/healthy-sugar-alternatives/

Many of you are athletes or fitness-focused individuals and currently use SweetBeat to monitor and track your HRV as it correlates to your training routine. In an effort to better meet your needs, we have added some features that are specifically designed for HRV recovery and training.

The latest release of SweetBeat can now be downloaded from the App Store.

When you press start, you can view a selection screen to monitor stress, run HRV For Training session or run a Heart Rate Recovery session. If you select the Help icon (question mark in a box) at the right of each session type, you will see the following screen.

Session Selection Screen

Select session

 

You can learn about the HRV For Training feature set by swiping to the left after you select the help ? button. The following six screens give you an overview of the new SweetBeat functionality.

HRV for Training over time

 

To run an HRV For Training session, select the session option, and press the start button on the main monitor screen. SweetBeat will automatically filter your HRV readings from your heart rate monitor and begin counting down a three-minute session.

The SweetBeat learning algorithm will establish a reference line over a few days as shown in the HRV For Training Over Time graph.

We recommend that you initially do light training or no training for a couple of days.  If you do train during initial sessions, the algorithm will compensate and adjust over the first 10 days of use, improving accuracy over time.

The HRV For Training Over Time graph will provide recommendations after each daily reading for a regular training day (HRV is above reference line), a light exertion day (HRV is below reference line for one day), or a rest day (HRV is below the reference line for two days).

If you wish, SweetBeat will remind you to take a daily HRV reading, with a selectable time that you preset. This reminder will appear initially when you select your first HRV training session. If you want to change the daily reminder time, you can access the preset in the settings menu under application settings.

Daily Reminder Setting

Daily Reminder

 

Charts for each session are included in history tab as well as cumulative charts for all sessions. HRV training sessions are tagged as HRV in the history screen.  You can also still select your own tag.

Good luck with your training! If you have any questions you can email us at support@sweetwaterhrv.com and we will reply within 24 hours.

SweetBeat Gets the Blues

Bluetooth is a wonderful invention. It enhances the mobility of the athlete, who no longer has to mess with wires while working out. It’s also a boon to the person who likes to garden or do other chores while listening to music. (I know one gentleman who bought Bluetooth headphones because he liked to garden while listening to music and snipped his wires with the garden shears once too many times.)

But when it comes to heart rate variability, not all Bluetooth is created equal. When SweetWater Health came out with our Bluetooth-compatible version of SweetBeat™, we tested several BT sensors to assure accuracy. Heart rate requires a lower sampling rate, and all sensors performed well for heart rate detection. But HRV requires a more frequent sampling rate to be accurate, which is why the iPhone camera sensor, at 30 frames per second, cannot deliver accurate HRV data.

You can use any Bluetooth v4.0 low-energy heart rate monitor with SweetBeat, including 60Beat and newer Polar H7 models with the iPhone 4S, 5, iPad 3 and newer iPod Touch 5 devices—with one exception. You cannot use Wahoo Blue HR. It’s fine for heart rate, but is not suitable for heart rate variability. This is noted in the app store description of SweetBeat.

We’re sorry for any inconvenience this may cause our Wahoo Blue HR owners. We have worked closely with Wahoo on this issue, but as of this writing, the technical issues have not yet been resolved.

Important Information for SweetBeat Users

2 Replies

SweetWater Health is a very young company. SweetBeat™, our iPhone app, has been on the market for just a little over a year. We started with no users at all (except for us SweetWaterites), and during the months that followed SweetBeat’s debut, we have watched with interest as our audience of users has grown.

And you, our users, have surprised us. We thought that most people would purchase SweetBeat to help reduce stress. There are certainly some users that fit that profile, but the dedicated users, the ones who really use SweetBeat all the time, are athletes—often elite athletes—who use SweetBeat for HRV training to help understand their bodies better and to optimize training schedules.

And you—our dedicated users—told us that the product needed tweaking so you could use it even more effectively. So tweak it we did, and we need to tell you about the changes we made. This is important to know even if you are not an athlete, as your HRV levels will appear lower than in previous versions. This does not mean your HRV has changed—only the scale.

SweetBeat version 1.2.2 (and beyond) includes a refinement of the HRV calculation algorithm to fine-tune it for athletes. Some of you ultra-fit individuals were “maxing out” the HRV reading at 100. The new algorithm fixes this with the result that the calculated HRV will appear lower than in previous versions of SweetBeat. We have included some charts to illustrate what you can expect with version 1.2.2.

For SweetBeat users who have been measuring HRV for athletic training, your HRV will appear to decrease with version 1.2.2. For this reason we recommend starting with a new baseline taken on a day that you know you are fully recovered. We believe this will provide more accurate results in the long run as your fitness levels improve.

Below are a couple of charts that illustrate how your new HRV scores may differ from your previous scores.

How is HRV calculated? SweetBeat measures the RR intervals (the time between heartbeats) then calculates the HRV parasympathetic parameter rMSSD. We then run a scaling algorithm on rMSSD to create an HRV value. Typical values will be in the range of 0-100. rMSSD is the square root of the mean squared difference of successive RRs. Elite athletes will experience very high rMSSD scores compared to others.

If you want to see the raw numbers, look at the “Geek Screen” on the flip side of the ECG heart beat screen. To see the Geek Screen, press the button in lower right corner of the window where the animated ECG appears. You will see the summary numbers from your last session. Below are the same charts from above that include rMSSD.

As a reminder on how to use HRV for training:

  1. Take your HRV every morning prior to any activity.
    1. This session can be measured sitting, standing or lying down, but be consistent in the position you select.
    2. Do a five-minute session.
      1. HRV is time dependent so be consistent in the length of the session
      2. If HRV drops significantly (more than 10 points) a low exertion or rest day is in order.
      3. If HRV drops significantly two or more days in a row, a rest day is in order.
