Stimulate your ‘Rest and Restore’ system!

I had never heard of the body’s ‘rest and restore’ system until recently when Dr Patricia Bloom* explained it was another name for the parasympathetic nervous system. I don’t know about you but I frequently  get the sympathetic and the parasympathetic systems mixed up.  One system fires us up and puts us in a state of readiness for action, triggered by threats of some kind or another (fight or flight response anyone?). So blood pressure rises, the body is flooded with hormones, muscles primed for action etc. That’s the sympathetic nervous system, the one I tend to think should be the kind, soothing system – i.e. ‘sympathetic’ but it isn’t). It’s also the system that in today’s modern world gets fired up too much of the time culminating in too much stress.

The other system (the parasympathetic nervous system or rest and restore system) relaxes the body and helps us chill out (technical term there). Personally I can get my head around rest and restore much more easily than parasympathetic…

Patricia explained that these systems work together a bit like a see-saw, so if one is up then the other has to go down. One way to reduce stress is to turn up the rest and restore system – the sympathetic nervous system will then quieten down. This results  in us feeling calmer, less irritable and stressed, and generally being nicer to be around!

Apparently in the last decade cardiologists have got really interested in the turning up of the rest & restore system; cardiac coherence is the term used to measure how well we’re doing on this front.

cardiac coherence = when breathing rate and the heart rate are synchronised in such a way that the rest and restore system is turned up.

Did you know that increased cardiac coherence is associated with being more athletic and healthy all of which is great for the heart? Got to be a good thing when you consider that heart disease is one of the leading causes of mortality amongst older adults.

A normal breathing rate is somewhere between 12-18 breaths per minute but most people experience cardiac coherence when they breathe at a rate of between 4.5 to 7 times a minute. Have you ever noticed that for most people when they meditate their breath becomes slower and more prolonged? They’re moving into cardiac coherence and thus reducing their stress.

But what if you don’t have time to meditate for a substantial period?

TRY THIS:   practice a minute of slow breathing to get into cardiac coherence.

I’ve been experimenting with getting my phone out – setting the timer for a minute, trying to breathe slowly and counting my breaths. I start off with a rate of about 6 and then by the second minute I drop down to just over 4 breaths per minute. It feels really good and I can’t believe it’s only taking just over a minute to experience cardiac coherence.  What about you? What’s your rate?

I’ve tested my normal breathing rate and it’s quite low to start with – about 9 breaths per minute so I reckon being at the lower end of the optimal coherence breathing rate (4.5) is about right for me.

Do have a go and see how it feels to reduce your breathing rate and please let me know below what you find out.  Give yourself a minute to help build your ‘rest and restore’ system!

    I actually have used this app. The free version allows a person to pick their desired breathing rate and for how long they want to do the breathing exercise for. Although you can watch the lungs fill up with air and release the air again while you breathe, you can also close your eyes and follow the tones. If you buy the monitor that works with the app, you can also track your breathing rate and progress. Since its free to download, its worth trying it out.

    Hi Kate,

    I found this extremely interesting and useful. One of the things I notice about myself is that when I am stressed I tend to hold my breath a lot. Actively focussing on my breathing as you suggest is a really useful tool for me to have. Thank you, Amyx

    Love this as a way of adding calm and restoration into a busy day. Think it could be something I could offer to clients as well as a way of starting to take time for themselves and help with stress levels.

    This is a very nice summary of recent research that I have been reading and keeping up with. If you are interested, there is also a free version of the app, “My Calm Beat,” that allows one to set thier breathing rate and also provides a visual and a timer to assist with slowing one’s breath down. Liking the articles and look forward to reading more.
