Bitesize Health Hack #1

You are invited to…

Breathe Deeply

What if you could enjoy less stress2,4, reduce anxiety1,4, improve immune function4, think more clearly5,12, build a stronger core5, get better sleep6 AND burn more body fat6, all by just breathing as nature intended? What if a simple, easy change to your breathing could give you more control over your life8?

Let’s have a little play…

Standing, sitting or even lying down, place one hand on your upper chest and another on your belly button.  Take a few normal breaths (through the nose if possible), then slow down and deepen your breathing.

Gift yourself a moment or two here to simply breathe and observe.

No really,  stop reading and do this before you carry on - just notice - are either (or both) of your hands moving as you breathe?  Are your shoulders moving?

If the hand on your chest is moving at all, then start to deepen your breath - really draw each breath slowly through your nose and chest and deep down into your tummy, encouraging the belly button, and your lower hand, to rise and fall expansively, while the upper hand (on the chest) becomes completely still.

It may take a little practice, but as you get into the flow of slow, deep belly breaths, your heart rate will slow down1, your blood pressure will lower1 and you will start to feel more relaxed as you start to short-circuit your fight or flight or survival brain1,2.



Take long slow, belly breaths EVERY time you think about it


Overcoming The Challenges

OK, I get it… who’s going to remember to do belly breaths all day every day if you're running around like a chicken without a head?  The easiest solution is to just pop reminder Post-it notes around where you spend most of your time. They don’t even have to say anything – you’ll know what they mean! Soon you won’t need them anymore – breathing into your belly will just be your natural state. You could also make it part of your bedtime wind-down ritual (post-it on your headboard?) And ten long, slow belly breaths just before bed will also promote better sleep 10.

When you’re stressed and anxious and need it most, taking time out to breathe might not always feel possible.  But the good news is that with a bit of practise, you can do this even while somebody is breathing fire in your face - and the only thing they’ll notice is the confusingly serene look in your eyes!

We’re used to keeping our tummies pulled in, so you might find a bit (or a lot!) of resistance to allowing it to bulge outwards. Let that go... literally.

You might find yourself trying too hard, or even hyperventilating… remind yourself to relax - keep it slow and easy, don’t force anything.

Because best of all, besides being the smallest change you can make for the most seismic impact in your health and happiness, this hack is not even going to take up any extra time in your day - there really isn’t anything you need to do here. I mean, you’re breathing already (well at least I hope you are) and you don’t need to stop what you’re doing to breathe – you just need to remember to do it a little differently.

My take on the


(if you’re all about “But why…?”)


Deep, slow belly breathing literally short-circuits your stressed out fight-or-flight mode in the body and brain.

Think about what happens when you’re facing down a sabre tooth tiger - or at least the modern-day version of one, an irate boss/teacher/family member. The instant that danger presents, you drop straight into survival (fight or flight) mode1. Your sympathetic nervous system kicks in and your body is flooded with hormones to help you fight or fly, your breathing becomes light and fast and your heart rate and blood pressure increase1. Your body is primed to deliver a killing blow or to blast outta there like the Flash. Now this is a fantastic physiological benefit when you are actually facing a sabre tooth tiger, but generally-speaking, it’s not appropriate to kick your boss on the ankles or roundhouse Aunt Martha to the kerb. Nor is it a positive on your career progression to run screaming from an overwhelming meeting room. This means we just don’t get the chance to ‘use up’ the hormones released whenever we have a stress response.

To make matters worse, if you’re living a typical modern-day life, you’re often facing down some form of sabre tooth tiger from the moment you open one bleary, resistant eyelid each morning till those last worry-filled moments on the pillow at night.

But what does this have to do with deep belly breathing, you may be asking? Well… shallow, upper chest breathing is part of the stress response2, so if you’re breathing this way simply from habit, you could be intensifying the negative effects of chronic stress on your body and also promoting more anxiety2,7.

Deep, slow breathing effectively short-circuits the stress response and instead engages the parasympathetic nervous system (or “rest and digest” response)8, lowering blood pressure and heart rate and reducing stress hormones in the body, leaving you feeling calmer and less anxious2.

In addition, when the body doesn’t have to focus on saving you from sabre-tooth tigers, it can direct more effort to the rest and digest functions in the body, releasing hormones to help with digestion and other vital processes in the body1. This means more nutrients and oxygen in the blood1, leading to more efficient cell repair and growth, enhanced organ function and more energy.

We know that chronic stress has a negative impact on the immune function and a number of studies demonstrate the link between deep, slow breathing and improved immunity2,9.

We also know that chronic stress can contribute to obesity, either directly (for example cortisol increases appetite) or indirectly through less sleep and exercise1, so breaking that chronic stress response may well help you lose body fat.

Another, more anatomical benefit of deep breathing is that the muscles that assist proper respiration also form some of your deepest core muscles. Breathing exercises can train these muscles in much the same way you would train bicep curls, resulting in stronger respiratory (and thus core) muscles5. On the other hand, shallow chest breathing recruits and tightens muscles around the shoulder, neck and back, resulting in bad posture, neck pain, headaches and increased risk of injury3. It’s no coincidence we hold stress in tight shoulders.

There is one more little thing that the survival brain does when you’re in fight or flight mode - it actually shuts down your ‘thinking brain’. That may seem counterintuitive, until you remember how long it normally takes to make a decision. That sabre-tooth tiger is probably not going to wait around while you carry out a full assessment of the available escape routes and distance to the nearest tree, while consulting Google as to whether sabre tooth tigers can climb trees. This lesser known effect of the stress response might give you a clue as to why we say such toe-curlingly stupid things in awkward situations7, 8!

While all this is going on, there is something else fundamental happening when you take control of your breathing. You’re jumping into the driver’s seat of a function that is usually carried out automatically by your survival brain, which also happens to be the part of your brain that carries out those automatic habits you find so hard to break.  So, if you’re going to break any habit, you need to disengage that autopilot and consciously take back the wheel, so you can get back in control of your life, with actions that are aligned more fully to your heartfelt intent.  This is not woo, this is neuroscience and I touch on it briefly here, because, in addition to all the physiological benefits of slow, deep breathing, this hack is also a first step in you starting to take control of your actions and habits. So, when it’s feeling a little challenging to keep breathing deeply, remind yourself that you are simply practising taking back control of your actions and your life.

As Carl Jung said… “Until you make the unconscious conscious, it will direct your life and you will call it fate.”

By this simple act of controlling your breath, you take your first steps into making the unconscious conscious and directing your own life. And isn’t that a pretty great first step to take?
