Does early morning yoga practice help or inhibit your muscle memory?
4My son is learning to ride a bike and he is not particularly thrilled about it – right now it’s neither easy for him, nor enjoyable. This reminds me of the frustration that some yoga students experience when they first begin to practice yoga. I’ve gotten those puzzled looks before from my newbie students: “You want me to put my foot where?!”
It takes time for any new activity to become more natural – we all know that “practice makes perfect.” This applies to any skilled routine, whether it’s riding a bike or being able to arrange different body parts into a specific pose. We call this mastery “muscle memory”. The term “muscle memory” is a bit misleading though. Muscles themselves have no memory; muscle memory is really brain memory. “Training and strengthening muscles can help you better execute a skilled memory routine. But the routine itself – the memory program – resides firmly and exclusively within the brain.” (1)
Last week we explored how sleep strengthens and preserves our textbook-style memories. Turns out, sleep is just as important for improving our motor memory, leading to increased accuracy and efficient automaticity of a practiced routine. Matthew Walker, PhD demonstrated in his studies that memory transference during sleep applies to motor memories, too. “Sleep had again transferred the memories, but the results were different from that for textbook-like memory. Rather than a transfer from short-to long-term memory required for saving facts, the motor memories had been shifted over to brain circuits that operate below the level of consciousness. As a result, those skill actions were now instinctual habits. They flowed out of the body with ease, rather than feeling effortful and deliberate. Which is to say that sleep helped the brain automate the movement routines, making them second nature—effortless.”(1)
In yoga it is generally useful to acquire basic skills of mind-body coordination, so that the poses seem more accessible and less threatening. However, it becomes even more important when we are working with specific injuries and are trying to modify our habitual movement patterns. If your body is used to moving a certain way, but that pattern of movement is creating pain, instability or imbalance, you can effectively use your yoga practice to modify those movement patterns. But, as you can imagine, changing the already entrenched movement patterns is no easy task and requires a lot of repetition.
This is one of the reasons that we often recommend that students establish a consistent personal home yoga practice – over time it helps to replace old, dysfunctional movement patterns with new, more beneficial ones. Here is a tricky part though. Often students are encouraged to do their yoga practice first thing in the morning. For many students this means waking up earlier to have time for their yoga before other demands of the day kick in. Unfortunately, Matthew Walker had demonstrated that improvements in the motor memory “were directly related to the amount of stage 2 NREM (deep sleep), especially in the last two hours of an eight-hour night of sleep.”(1) This means that if you are cutting your sleep short to get up and do your yoga routine, your brain will not have time to improve and strengthen your motor memory from the day before. So instead of using your sleep to assist you in your practice efforts, you will be undercutting them.
Another unfortunate side effect of shorter sleep time is the risk of injury. A research study of competitive young athletes in 2014 demonstrated that chronic lack of sleep dramatically increased the risk of injury.
Most of us are not competitive athletes, but the same principles apply to all of us, as well. Lack of sleep generally increases the risk of injury, especially when you are physically challenging your body.
Here is the bottom line: If you are trying to resolve muscle tension or decrease physical pain in your body, it is very useful to regularly practice a short therapeutic routine designed specifically for you by a qualified professional (physical therapist, yoga therapist, etc.). And to make sure that this new movement pattern becomes the default pattern for your body, you need to get at least 8 hours of sleep to allow for those motor memories to be processed and integrated by the brain. This will also significantly decrease the risk that you will re-injure yourself.
Next time we will take a look at what lack of sleep does to your emotions (and it’s much more than just making you grumpy). Tune in!

Early to bed and then morning Yoga practice. I like your blog posts very much its a bit misleading to give just one scenario – sleep deprived yoga practice – and say it is best to avoid it.
I practice Yoga asanas every morning and, just light body movements to wake it up. It works wonders how the day is so much more improved.
On this I agree that morning and evening practices need to be different. However, I didn’t see that mentioned, only derived.
Thanks for your wonderful posts though 🙂
Thank you for your comment! I completely agree – going to bed early and getting up early to practice can work very well. This is why I wrote several times that it is about getting at least 8 hours of sleep, not about the specific time when you decide to practice. Thank you for reading!
nice post! sleep is very important, ando sometimes i´ve heard yoga teachers recommending waking up at 5 am to do yoga. That may not work for everyone!
My personal experience with ‘sleeping hours’.
I am a Yoga teacher and endurance sports trainer and enthusiasist.
The days I teach and practice only Yoga, I feel fully refreshed and recharged with 5 to six hours of night sleep. I take a noon nap of 15 minutes also.
The days I teach and practice endurance sports, cycling, running, rock climbing and gymnastics, I feel fully refreshed and recharged only after at least 8 hours of sleep. I also need a noon nap of 30 minutes.
As I understand this, the practice of Yoga tunes me into a state of mind-body calmness, which results in optimization of body functions, resulting in surplus energy reserves during the day. So when I go to bed, I am in a mind-body that is in a balanced state. So finally this results in less time required for repair-recovery-rebooting-rest. So I am fully refreshed and recharged with 5 to 6 hours of sleep.
On the other hand, my sports training and practice, pressurises the mind-body. So when I go to bed, I am in a mind-body that is out of balance ( Even though I have done a 45 minute Yoga practice after my sports training and practice ). So finally this results in more time for repair-recovery-rebooting-rest. So I am fully refreshed and recharged with at least 8 hours of sleep.
I conclude by understanding that the number of hours of sleep each individual needs is dependent on the cumulative mind-body state of that individual.
I am also aware that historically there have been and there are individuals who have lived a very productive life with less than 4 hours of sleep.
