I am well aware that I sound like everyone’s Grandma when I say, “Stop slouching, posture is important!”. But the thing is, Grandma was on to something! The more we learn about the human body, how it interacts with the world around us and how it works to keep us alive, the more integral posture becomes.

Why is it bad to slouch?
When our head drops forward and our shoulders round down and forward, this sends a feedback signal to our brain, specifically an area called the red nucleus. The red nucleus is always on the lookout for signs that you are in danger, and this slumped posture is a big red flag for it. When the red nucleus thinks you are in trouble, it rallies its friends (other nuclei that are in the mesencephalon) and makes you hypervigilant. These friends start a cascade of defence mechanisms within your body, releasing cortisol (a stress hormone), tightening muscles, increasing your sensitivity to light and sound, all so you can be aware of any impending danger and be ready to run or fight at a moments notice. Yes, your poor posture just switched on your ‘fight or flight’ response and made you stressed!

How does your poor posture make you irritable and tired?
When your fight or flight response is turned on, it makes you hypervigilant. Your brain is looking for any signal that you are about to be attacked, and your body is not worried about any basic functions like digesting food properly or keeping up your immune system, because there will be time for that once the danger is passed! It is hard to sleep, because your brain will wake you at the slightest sounds. You are sensitive to light and this can lead to headaches. So you are tired, overwhelmed and getting headaches, of course you are going to be cranky and irritable! The slouching posture can also decrease the range of movement of your ribcage while you breathe. This can mean that you take shallower breaths, which can affect the oxygenation levels in your body, making it harder for your cells to work efficiently and making you even more tired.

Why does my back hurt?
Part of the stress response we outlined above is muscles tightening. The muscles across your shoulders and up the back of your neck get very tight as part of this, and your low back can also get tight as your body has to compensate and redistribute the weight to keep you upright. A slouched posture is not a mechanically sound position for your body. It disengages some larger muscles (like lower trapezius and deep neck flexors) and puts their work onto muscles not designed to take such a big load (like smaller spinal extensor muscles, superficial neck flexors and suboccipitals). This can leave you stiff, sore and more prone to injury.

What is good posture?
Unfortunately, there is no such thing as ‘perfect posture’. There are definitely some positions to avoid, like the slumped forward posture we have talked about, but the key to good posture is… *drum roll please*…. Movement! Our bodies were not designed to sit in one position all day. Our muscles and brains thrive on movement and the feedback it provides. Taking regular breaks to move and stretch every 15-20 minutes can decrease back pain and increase your productivity. Following good ergonomic advice with your workstation set up is also a good idea, and if you are lucky enough to have a sit stand desk, varying the height so you can go between sitting and standing throughout the day. It would take far too long to write out all the ways to keep moving, so if you would like more information, have a look at our Facebook live videos this month at #SundayLiveAt8

So why is posture important? Because it can affect every system in our body, and make us tired, moody and sore if we aren’t getting it right. Make sure you check out our live videos this month, and if you have any questions please message us or talk to us during your appointment.

While sometimes it may be tempting to do this when someone mentions gratitude, the benefits are greater than you think!

How being thankful can make your brain happier
It can seem obvious, being thankful for what you have. But it can be easy to fall into the trap of ‘I’ll be happy when…’, waiting for the stars to align and make ‘everything perfect’. In reality this very rarely happens, and we can make ourselves pretty miserable waiting for it.
Comparison is the thief of joy. If you are always looking at what others have or have achieved, it can be very hard to celebrate your own wins or be grateful for the good things in your life. The grass is not really greener on the other side!

How your brain will thank you
Being grateful can make massive changes to your life. It can help you express more positive emotions, feel more alive, sleep better, express more compassion and kindness, and even have stronger immune systems. It does this by affecting how your brain is functioning- when you express gratitude it affects your hypothalamus (where your stress response is triggered), and your ventral tegmental area (the part of your brain responsible for your reward mechanism that can produce feelings of pleasure). People who have practiced gratitude for as little as 3 months have huge changes in their brain on functional MRI in these areas and others, most to do with pleasure, positive emotion and lowered stress response.

First steps
Sometimes it can be easier to recognise what others do for you, before you can see what positives you already have. So, make a start by thinking about the people in your life that help you or do nice things for you. If you are really struggling with this, try to flip around any negatives you notice about people. Rather than picking on what they have missed or could have done better, say thank you for your effort and thanks for making my life a bit easier.
There have been studies that have shown that acting happy can actually make you happy. Smiling has the same effect on your brain whether you want to smile or not. So, you can try a little bit of ‘fake it before you make it’ to help you start.

How to be grateful
There are so many strategies that you can implement to help you show gratitude. Keep it simple and find what works for you. This shouldn’t be a hard or laborious task, so if you’re finding it difficult, start small and make it easier on yourself.

1. Write it out. Make a small list of 3-5 things you are grateful for each day. Pick a time that works for you, first thing in the morning or just before bed, and write down what you are thankful to have in your life. Try to change it up a bit though, writing the same things everyday doesn’t fire your brain in the same way as if you are always thinking of new things, or putting a different spin on what you are grateful for. You could also try writing letters to those who you are thankful for. It doesn’t matter if you don’t send them (although that could be a nice thing to do!), even just writing the letters can give your brain a positive boost.
2. Gifts. These don’t need to be large or extravagant, just a token of your appreciation of what others do for you. Gift giving is an extremely positive event in your brain, and it’s always nice to receive something unexpected too! And it doesn’t need to be a physical gift either. Giving your time to someone, whether it is to help them with a task, or just be with them and make a connection, can be a very powerful way to show how thankful you are to have them in your life.
3. Saying thank you! Actually sincerely saying thank you to those around you. The trick here is to be genuine. It doesn’t need to be a big extravagant show, just a simple ‘Thanks for doing this, it really helps me’. This one has an added benefit for the person receiving the thankyou too. Workers who are regularly thanked for doing their jobs well are up to 50% more productive than those who are not.

​
Gratitude is more than just being optimistic or looking on the bright side. It is looking at what you have worked hard for, what you have achieved, how much you have in your life. Even if you first think there is nothing, when you start to look a little deeper there is usually much more than you expect. It is easy to get caught up in the negatives, what you don’t have and what you can’t do, that it can be tricky to appreciate what you can do. Be thankful for what is in your life right now, even if it is a bit challenging, and look forward to everything coming your way in the future. Try it out, if nothing else your brain will thank you for it!
