Expert Physiotherapist On How Yoga & Pilates Can Transform Your Mind


We know exercise like yoga and pilates can improve strength and flexibility, but how does your mental state change so rapidly? And importantly, what mechanism occurs in the brain-body connection to create the change? Chris Jellis is a brilliant sports therapist and director of Melbourne’s Sum of Us studio. Today on the blog he shares the incredible power of Yoga and Pilates to transform the mind…


I am going to share with you how that happens, and some exciting new research proving it, but first let’s have a look at pilates and yoga. The rise of yoga in Australia has been meteoric in recent years. The Australian Bureau of Statistics has 1.9% of the Australian population as regularly attending a yoga class which accounts for about 400,000 people in Australia alone.


It started as a mindful practice in India in the 5th century, because its originators have always known its powerful effect on helping us slow down. But until now, it was largely unknown how this happened in the brain. So that brings us back to today’s question, which is can you move your body in certain ways to affect your brain, and ultimately your mood?


Late last year Neuroscientists at the University of Pittsburgh have, for the first time, identified a set of complex networks that connect our cerebral cortex to our adrenal medulla.


Before I lose you, let me explain some anatomy. The cerebral cortex is part of the brain that controls our executive functioning. It is the driver of the car so to speak, and allows us to think, move and act. The adrenal medulla is found in the adrenal gland (just above the kidney) and is responsible for the body’s production of stress hormones such as adrenaline. It is just a simple gland, but has a huge effect on us because of the way adrenaline interacts with our emotions.


When adrenaline pumps for long periods of time, such as in states of chronic anxiety and depression, irreversible changes can occur in the vessels of our body, leading to hypertension and stroke.


What these scientists were able to find were the direct neural connections between the body and the brain. And on the surface this makes a lot of sense. 1000 years ago if you saw a tiger, your cortex would send a message to your medulla. The medulla would fire up and pump out adrenaline to make your muscles tense and your heart beat faster, getting you ready to either run or fight.


What shocked the researchers was the sheer number of circuits they found connecting the two, and also where they were found. What was once seen as a one way simple connection, now revealed a whole new tapestry of networks.


The one we are most interested in was the section of connections they found that came from part of the cortex that controls our core body movement and posture. This was a surprise, because what would core body control have to do with stress?


Well it was hypothesised that from an evolutionary perspective, in times when you be balanced and  steady, your cortex evolved to speak directly to the medulla. Imagine for instance making an unsteady crossing over a raging river. To allow you to be more still, calm and safe, your cortex could mediate your internal hormonal production through this direct connection.


This is a pretty amazing discovery. Most people are under the impression that they need to fight mental stress with a mental strategy. Meditation, talking to a psychologist, seeing a councilor –  these are all highly valuable and necessary. But they don’t work for everybody. Some people even find it frustrating and simply can’t quiet their mind or their nerves.


It’s important to note this is very different from previous findings on how exercise influences us psychologically. Science has known for many years that cardiovascular and intense strength building exercise can release endorphins, which improves our happiness levels. But never previously have they found a connection directly to modulate adrenal activity and ultimately lower anxiety.


Dr Strick, one of the head researchers puts it this way, “One way of summarizing our results is that we may have uncovered the stress and depression connectome.”


So next time you are feeling stressed, why not try it out? You can choose to do core or control based movements (such as yoga, pilates, dancing, tai chi etc). Challenge yourself to fully engage your brain and focus on the activity. Make sure it involves deep core contractions, and has an element of difficulty for your balance.


A really good example is holding a double arm plank, then shifting into a single arm side plank to the side (do this off your knees if you have back pain or find it too difficult off your toes). We recommend at least 15 minutes of different movements; you could add triangle or tree pose. Focus on your breathing, and deep core contractions and the control of the movement. Then just switch your mind off and allow your cortex to take over. It can be quite liberating to know that simply moving your body in certain ways can module your internal responses to emotional stress, keeping you healthy and happy!

Hi Jessica, I believe in synchronicity so when I was guided to you .on FB I was intrigued and inspired. I turned 46 last week and my husband bought me your book. I wanted to thank you for sharing your wisdom in such a beautifully presented way. My  copy is now filled with tabs and post it notes with actual notes throughout. I am dairy intolerant since having my gallbladder removed 15+ years ago, I don't eat meat, very minimal gluten and was told 12 months ago my gut was not digesting my food properly so I wasn't receiving sufficient nutrients and taking supplements would be a waste of time.  My weight fluctuates tending to gain rather than lose but now I believe I have a tool to help me bring my body back into balance that I need for my health and longevity of life - so again thank you. The first few steps to creating a stronger path forward for my health has found its foundation in your beautiful book, The Healthy Life.

With kindest regards Samantha

I'm writing this email because I wanted to tell you how much I love your blog and how you really helped me in my health journey. Thank you for sharing all your advices and experiences.

When I started my studies, I was drinking lots of coffee and I was eaten the wrong foods, and feel bad about it, I wasn't at my best. So I had done some research on the net but at first I didn't found advices that are for me, and then I found your blog. It was exactly what I was looking for, good advices and healthy recipes. Now I'm following your advices on rest more, and snacks between meals and prep the meals and take time for myself to reconnect with my body and let go my anxiety, etc, and I have a more balanced life and have a new relationship with food thanks to you.

I bought your book and it's honestly the best book I have ever bought. I suffer from IBS and anxiety. I have paid so much money seeing naturopaths however after reading your book and all of your tips I'm noticing so much of a difference, so simple and easy to follow. And symptoms have dramatically decreased. Also you have helped me to relax. Currently drinking the protein health smoothie! Thankyou your amazing.


Hey Jessica!
I haven’t yet brought ‘The Healthy Life’, but I do have the clean life and your slim down plan! I would like to thank you so much for the knowledge your share and the message you put across about health and wellness. I’m studying Nutritional Medicine in Melbourne and absolutely love the philosophy that you share with your JSHealth community. The work you’ve done to show people that leading a healthy lifestyle isn’t boring, tasteless, difficult or depriving is amazing and hope to share the message myself one day. You’ve inspired me to start my own blog , to share the message and have taught me so many things about my own health! You should be proud of your achievements! Thank you again

- Jacinta

I searched for help and tips through the Internet and found Jessica Sepel. This is seriously not exaggerated, but she was the reason why I have dared myself to eat again, to have snacks in between, to nourish my body. I could slowly improve my negative thoughts about my body image and my stupid anxiety of gaining weight. Besides, The Cleanest Gut was awesome too! A huge thank you! Especially from my mum. Seriously, without you I wouldn’t be where I am now!


Congratulations on your new book! It looks absolutely gorgeous. I’ve been following you on Instagram for a few years and you’ve inspired me to slowly but surely eat healthier without giving myself a hard time when I don’t. It made me so happy (and weirdly proud) to see the Daily Mail article on The Healthy Life. I remember trying out your recipes before you even had your eBook out! I can’t wait to get my hands on the book. Keep up the great work.

Cooking in this way truly brought out the foodie in me and has instilled a huge passion for health and wellness! Life throws you hard and frustrating things sometimes but I truly believe that this is where we learn more about ourselves and what our passions in life are! Thank you for inspiring me on my journey to health and wellness!


I am a yoga teacher in Johannesburg and am thrilled to have bought your book today. I love making healthy, nutritious food for my family, friends and fellow yogis! Thank you for this book and your inspiration (had to share a pic of my book on my recipe stand in the kitchen).

– Helene

I bought your beautiful book during the week and told my bestie to go out and buy it also! I love love love it. It is the book I would give to my younger self if I could (I am 41 years old). Everything is just so sensible and informative and is definitely a book all teenagers should have. This should be a text book for girls becoming teens. I will love going back and re-reading it many many times and can't wait to make more of the recipes. Thank you Jess - you are an incredibly inspiring woman and you should feel so proud

Michelle Curtis
