Gadget Review: Inner
Balance
Review By Casey
Douglass
Heartmath have a nifty
gadget called the Inner Balance. It connects to your smartphone and,
by monitoring your heart-rate variability, gives you feedback as to
whether you are in the synchronised state known as heart coherence.
Heartmath UK+IRL kindly sent me an Inner Balance to have a play with,
and after a few months of experimentation, I finally feel ready to
put some thoughts out there.
The Inner Balance &
The Inner Balance App
The Inner Balance
sensor is a small, light, pebble-shaped device. It has a clip on the
back to attach it to your clothing, and a wire that connects to an
ear-clip. The plastic body is home to one large rubbery button to
turn it on and off, alongside a tiny blinking led for status updates.
The whole thing is very comfortable to wear, and I was particularly
pleased that the ear-clip didn’t pinch; it just gently clasped. My
sessions lasted anywhere from 5 to 20 minutes, and I never became
uncomfortable with the device. This is a great thing, as you don’t
want unnecessary distractions when you are trying to focus.
I installed the Inner
Balance app from the Google Play Store, and my Android smartphone
connected to the Inner Balance via Bluetooth without issue. The app
itself is home to a lot of stuff, and to be honest, I could probably
write a whole review on just the app alone. It contains tips and
tutorials, your own logs and journal, and even synchronises to
HeartCloud, a free account that you can sign-up for, that allows you
to compare your coherence stats with others in a global community.
The most important element of the Inner Balance app however, are the
breath pacing animations that it uses to help you to enter into a
state of heart coherence.
What Is Heart
Coherence?
Research has shown that
the heart and the brain communicate in both directions, each
affecting the other in a variety of ways. If someone is in a state of
coherence, these interactions will be more harmonious or beneficial.
When someone is not in a coherent state, these signals can become
disrupted and more chaotic. The Inner Balance measures the user’s
level of coherence by way of their heart rate variability (HRV). When
you are in a coherent state, the graph of your HRV, when plotted over
time, will look closer to a smooth sine-wave pattern. When you are in
a non-coherent state, the plot is more irregular and jagged. The
Inner Balance app gives you the on-screen pacers and feedback
information you need to effectively put Heartmath’s Quick Coherence
Technique to work, and to bring yourself into coherence.
The Quick Coherence
Technique is very simple. The first step is to bring your attention
to the area of your heart and to slow your breathing until both your
inhalation and exhalation each last around five seconds. The second
step is to try to feel a positive, heart-felt emotion, such as love
or appreciation. As far as I understand it, the change in breathing
rhythm helps to shift your nervous system into a more balanced state,
and the heart-felt emotion further amplifies this effect. There are
other techniques in the Guides section of the Inner Balance app, but
the Quick Coherence Technique is the main one that I used.
The Inner Balance App
Part 2
The Inner Balance app
gives the user a number of animations that help to get their
breathing into a suitable rhythm. It’s worth noting that the target
breathing rhythm and many other session settings can be altered to
taste. It’s best if you try each of the breathing animations or
views to see which is most pleasing. The first two feature large
animations to set your breathing to. I did find that these tended to
chug at times on my low-end smartphone though. You can also have a
mini-HRV graph undulating above some of the animations. I personally
found this to be distracting but it is something that you can easily
turn off. All of these animations (and their accompanying sounds)
give you feedback as to what your coherence level is. Or you can
choose to sit with a screen of data, one that presents you with a
number of graph plots, including your HRV, Coherence over time, and
your Pulse.
I appreciated the tools
that the Inner Balance app provided, and the configurability it
offered. It didn’t take me long however, to feel that the chiming
sounds and the information on-screen served as more of a distraction
than any thing else, so I promptly muted the sounds and soon adopted
a practise of using the animation to set my breath rhythm and then
looking away. This suited my mindset and my practise but I didn’t
find anything particularly wrong with the app. It crashed
occasionally, as any app will, but that only happened once during an
actual session, and I had almost 170 sessions with it before I wrote
this review.
My Experiences
So how did I get on?
Did those 170 sessions with the Inner Balance give me any noticeable
benefit in my life? The answer is, I think so. It was subtle, but it
was there. It’s really great to have a device like the Inner
Balance that can give feedback on what you are doing. I’ve lost
count of how many times that I’ve read a certain breathing
technique lowers stress or activates your parasympathetic nervous
system and relaxation response, among other things. It’s one thing
to believe that the technique helps, it’s another thing entirely to
have data on the screen of your smartphone that actually proves that
you are entering a certain state, even if it can’t quantify every
knock-on effect that said state might have in your body.
I’ve been engaging
with various meditation practises for decades. I'll admit that when I
was a teenager, this was in the hope of developing some kind of extra
sensory perception. As life has continued, and my health has taken a
dive, I’m more than happy if a meditation or a mindfulness
technique just helps me to experience a little space between
miseries. I’m saying all of this to highlight that I didn’t come
into this as a total novice, and altering my breathing and focussing
in certain ways comes quite easily to me. As an aside, I’d like to
think that there is some kind of depressive rock band somewhere, or
at least a song, called “A Little Space Between Miseries.”
When I performed the
Quick Coherence Technique, I could see confirmation on my smartphone
that my HRV was responding to what I was doing. Sure, I wasn’t
given proof that I was relaxing or that my brainwaves had changed,
but I was given enough reassurance to know that I was doing the
technique properly, and that my body was responding, and that felt
very liberating. My coherence score and the ability to make notes in
my in-app journal after the session, meant that I could easily see
what helped me to achieve a higher level of coherence. As an example,
when trying to cultivate a heart-felt positive emotion, I found that
a feeling of appreciation consistently seemed to give me higher
coherence than the feeling of love. I wouldn’t have guessed that
would happen. True, it could be that I’m not very adept at
cultivating love in that way, and that might change over time, but as
something concrete to point at and to ponder, it was valuable to
note.
For me, the state of
coherence itself felt like a bit of space had opened up. Yes, a
little space between those miseries I mentioned a short while ago. A
five or ten minute session left me feeling calmer, and less easily
triggered by my thoughts. I’ve suffered with Obsessive Compulsive
Disorder for around thirty years. When my body is in an anxious or
triggered state, any negative or fearful thoughts can continue to
amplify my fight, flight or freeze response for some time after I’ve
calmed down. On the occasions where I had a short session with the
Inner Balance after the first peak of my anxiety, I noticed that the
same, intrusive thoughts didn’t have quite the same effect again.
They were still there, but a bit further away. A bit like if you have
a wasp in your room and you manage to shepherd it to the window,
which you promptly close once its outside. It might still be bouncing
against the glass, but as it’s on the outside now, it doesn’t
upset you so much. That’s kind of how I felt.
In a broader sense, I
felt other benefits too. Having an Inner Balance session before
getting to sleep did seem to give me a slightly better night’s
sleep. My sleep felt like it had a different quality but again, it
was a subtle difference that felt slightly better to me. I think that
my sessions with the Inner Balance also settled my stomach a little.
Again, nothing I’d shout from the rooftops about, but it seemed to
be a change for the better and it seemed to last. I can’t say that
I noticed any improvement in my concentration levels or in other
areas related to any kind of mental or physical performance, but my
health is pretty grotty at the best of times, so it’s not always
easy to discern these things.
Let’s Plot Some Data!
I was also curious to
see if I could increase my coherence levels over time. The goals that
already come in the Inner Balance App suggest practising three times
per day for at least five minutes, with a longer fifteen minute
session once per week to build your Coherence Baseline. This I did,
as best I could, for almost fifty days in a row. Some days might have
only had two sessions, but the vast majority had three. I decided to
plot my results on the graph below:

My days of A-level
maths are a long way behind me but I think I made a decent go of
things. I decided to calculate the average coherence across my
sessions for each day. This melded my session coherences into one
figure that was easily plotted. If I had three sessions with a
coherence rating of five on a given day, the average for that day
would naturally be five. This approach also allowed me to plot the
sessions where I hadn’t really committed to being so routine with
things. The two red data points on the graph above are the bookends
for my “three times per day” experimental period. The zone to the
left of the first red point was a time when I was a bit haphazard and
didn’t do my sessions every day. The zone to the right of the
rightmost red spot is where I relaxed things to just one session per
day. I plotted the averages and asked Open Office Calc to draw a
trend line, which you can see in a tasty plum colour.
Before drawing the
trend line, I did get the feeling that the data points became more
focussed in the 5-6 Coherence band, but to see the trend line paint
the picture of a slow increase was heartening. I will also add that
one lower coherence session in a day really scuppers the average when
the other two were nice and high. I also found that coughing drags my
coherence level down too. Guess who has a chronic cough? Yup. Me. I
think the graph speaks quite well for itself, so I will let you draw
your own conclusions.
I
also wanted to add that in the middle of my stricter experimental
period, I tested the Audio Visual Coherence Breath Pacers, also
available from Heartmath UK+IRL, which were included in those
averages depicted above.
Final Verdict
When I started using
the Inner Balance, I did so with an open mind and with the hope that
it would be beneficial. I didn’t expect miracles, and I didn’t
expect any changes that might occur to happen particularly quickly.
Like many things to do with health, the change is gradual, but I do
feel that I could see the benefits of using the Inner Balance, even
in such a relatively short period of time. I also think that it’s
really helpful that even a five minute session, a couple of times a
day, can seemingly give you a helping hand. When it became time to do
a session and I didn’t feel like it, the thought “It’s only
five minutes!” really helps remove some of the friction towards
taking action.
It is here that I will
mention the only hiccup that I had with the actual Inner Balance
device, and it’s a minor one. The clip that fastens the Inner
Balance to your clothing is a nice chunky thing. It has a little bump
near the hinge that you can push on to lever the clip one-handed.
Near the end of my 170 sessions, that little bump snapped off. Its
loss simply means that I have to pull the clip open from the other
end, and that’s easy enough to do. My Inner Balance was a
demonstration model, so I have no idea how old it is or how many
people played with it before it came to me. I can’t even be sure it
wasn’t my fault and that I didn’t try to open it in a mindless
way.
The Inner Balance is a
great piece of technology and it does what it sets out to do with a
minimum of fuss. The Inner Balance app lets the user tailor many
things to their own taste, and the whole thing does a fine job of
getting out of the user’s way. If you want to experiment with any
kind of focussed or meditative state and have a thirst for a way to
measure your progress, the Inner Balance seems to be a good solution
for that thirst.
