NuCalm feels very much like drifting peacefully off to sleep, though you probably won’t actually fall asleep.
Instead, you’ll hover at the edge of sleep, having your thoughts free to roam. Often, your mind is still wandering, while your body feels as if it is in deep sleep.
You'll feel your body start to get heavy; your breathing will become deeper; and your heart rate will slow down. A tingling sensation is normal - this is blood flow; slight twitches are also normal - this is muscles relaxing.
Even if your mind is wandering the whole time, you'll notice that your body is still and doesn't want to move. This is because it's in recovery. And though you're not asleep, you'll feel disconnected from your environment.
The natural endpoint of your session is when you "reconnect" and feel like moving again. This is typically between 30min and an hour for beginners. As you use NuCalm more consistently, the natural endpoint will start to shorten as the amount of time needed for your autonomic nervous system to balance will decrease.
