“In over ten years of practice, one pattern comes up again and again: clients who come to me for anxiety, stress or trauma almost always mention that they can’t sleep. The two are rarely separate problems.”
Samantha Grant is a Cognitive Hypnotherapist, NLP Practitioner and PSYCH-K® Facilitator based in Berkshire and Buckinghamshire. Over a decade of clinical practice has shown her that sleep difficulties are rarely about the bedroom.
They are almost always about the nervous system.
“People come to me with anxious thoughts, stress, trauma, or patterns of thinking that are keeping them stuck,” Samantha explains.
“Sleep problems are one of the most common things that comes alongside that. And the reason is straightforward once you understand what’s happening physiologically.”
The nervous system and sleep
Your nervous system operates in two states.
- Fight-or-flight keeps you alert, heart rate elevated, thoughts racing.
- Rest-and-digest is the opposite: breathing slows, tension releases, and sleep becomes possible.
“When someone is living with chronic stress or anxiety, their nervous system is often stuck in fight-or-flight,” Samantha says.
“It doesn’t matter how good their sleep hygiene is. The nervous system is still treating the world as a threat. And you cannot sleep properly when your body thinks it needs to stay alert.”
“The harder people try to force sleep, the worse it often gets. Lying there watching the clock, worrying about how tired they’ll be tomorrow, trying to ‘turn off’ their mind… All of that keeps the fight-or-flight response active.”
The vagus nerve: the body’s off switch
Research conducted at institutions including Harvard and UCLA has highlighted one nerve as central to regulating this: the vagus nerve.
It is the master controller of your autonomic nervous system, responsible for managing the shift between fight-or-flight and rest-and-digest.
When the vagus nerve is functioning well, the body knows how to wind down.
When it is dysregulated, that shift becomes difficult or impossible, regardless of what else you try.
“This is consistent with what I see in practice,” Samantha says.
“The subconscious patterns driving anxious thoughts and stress also keep the nervous system in a state of high alert. The therapeutic work I do with clients addresses those patterns directly. But the vagus nerve piece is real, and it’s worth understanding.”
How Samantha works with clients
“Using cognitive hypnotherapy, NLP and PSYCH-K®, my work focuses on identifying and changing the subconscious beliefs and patterns that are keeping someone’s nervous system stuck,” Samantha explains.
“That is where the lasting change comes from. When those patterns shift, clients often find that sleep improves alongside everything else.”
Where Nurosym fits in
“Through my interest in the research around vagal nerve stimulation, I came across Nurosym,” Samantha says.
“What drew me to it was the evidence base. It has been tested in over 50 scientific studies, including randomised placebo-controlled trials, and holds certified device status. That’s not something you see often in the wellness space.”
Nurosym uses patented AVNT™ technology (Auricular Vagal Neuromodulation Therapy) to deliver gentle electrical stimulation through the ear, directly targeting the vagus nerve.
In scientific studies, this approach improved vagus nerve activity by 67% after 5 minutes, a key marker of how well the nervous system is regulating itself.
“I want to be honest about what this is and what it isn’t,” Samantha says.
“Nurosym is not a solution to sleep problems on its own, and I would not present it as one. Sleep difficulties are rarely simple, and they usually need to be addressed at the level of the patterns and beliefs driving them. What Nurosym offers is physiological support for the nervous system alongside that work. For some people, that additional layer of support can be a helpful part of the picture.”
“It addresses something real. But it works best when it’s part of a broader approach, not a replacement for one.”
The device requires no prescription and no special technique.
You clip it to your ear and wear it while you wind down, read, or get ready for bed.
