Daily use is ideal. We recommend 3-4 times a week, 20-min minimum. NuCalm is balancing your autonomic nervous system. If you are using it every day, there is less balancing to be done each time. The natural endpoint of your session is when you start feeling restless and just “wake up”, similar to waking up from a nap. Going to your natural endpoint [link to natural endpoint article] means you have achieved complete autonomic nervous system balancing for the day. The length of your natural session is an indication of how out of balance you are. Sleep deprivation, poor sleep quality, stress, jetlag, illness, injury are all factors that will affect the length of your session. With consistent use of NuCalm, you will see that the natural endpoint of your session will become shorter over time.
