Goodbye panic attacks and anxious moments
Intense moments, calm in under a minute
When tension rises, your anchor is around your neck: breathe in through the nose, breathe out slowly through the pendant, and the body receives the calming signal along the vagus nerve.
The daily micro-calm ritual
Worn every day, it becomes a physical reminder: a few long exhales between meetings, in traffic or while queuing. Calm is trained exactly like a muscle, through repetition.
In the evening, instead of screens
Two or three minutes of long exhales in bed prepare the body for rest: lower pulse, relaxed nervous system, a natural transition into sleep.
Steel, engraving, zero batteries
A single object, no apps, no chargers, no subscriptions: the physics of your breath, cast in stainless steel and engraved with the NeuroGenesis DNA logo.
Everyday stress and restlessness
The extended exhale, guided by the calibrated channel, stimulates the vagus nerve, the body's natural switch between fight-or-flight mode and its calm-and-restore mode.
Sleep and switching off
Used in the evening, instead of your phone, it supports the natural transition into sleep: slow breathing rhythm, lower pulse, a mind that gradually settles.
Quitting smoking and vaping
The same hand-to-lips gesture, but you breathe in calm instead of nicotine. The familiar gesture stays, the habit changes, and this is one of the most popular uses of the tool worldwide.
Focus before important moments
Three long exhales before a presentation, an interview or a difficult conversation: discreet, silent, without anyone around noticing a thing.
What the studies show about extended-exhale breathing
a day were enough in the Stanford study: the extended exhale improved mood, reduced anxiety and lowered the resting breathing rate, outperforming mindfulness meditation.

What happens in your body and brain when you exhale slowly
Breathing is the only autonomic function you can consciously take over, and through it you reach the nervous system directly. When the exhale is guided correctly, the vagus nerve increases its activity and the body switches from survival mode into parasympathetic mode: the pulse drops, muscle tension eases, recovery processes restart, the mind clears. Every use is an anti-stress breathing workout.
The main nerve of the parasympathetic system links the brain to the heart, lungs and organs. Its tone, measured through heart rate variability, is a marker taken seriously in longevity: good vagal tone means a nervous system that bounces back quickly after stress.
Unresolved stress keeps cortisol high, and chronic cortisol is associated with inflammation, fragmented sleep and accelerated ageing. Anti-stress breathing training is studied precisely for switching off this repeated alarm: stress moments stopped in time add up, over the years, to a body that ages more gracefully.
Calm has its own chemistry: acetylcholine, the neurotransmitter of the parasympathetic branch, and breathing practices are studied in relation to GABA, the brain's main inhibitory neurotransmitter, associated with reduced anxiety and inner quiet.
Under stress, the amygdala takes command and thinking narrows down to survival. In calm, the prefrontal cortex regains its resources: working memory, decisions, creativity, learning. Clarity only arrives once the body has settled, and relaxation becomes a multiplier of mental performance.
CALM One is pure mental biohacking: every use is a real physiological switch, and the effects compound over time, just like training.
A piece of jewellery that works for you
CALM One looks like a minimalist piece of jewellery and works like a precision instrument: 304 stainless steel that keeps its look for years, NeuroGenesis DNA engraving, a calibrated air channel, completely silent in normal use. It cleans in seconds with warm water and soap, and the 60 cm chain places it exactly within reach.
From a panic attack to a child's first lessons in calm
When you feel panic coming
In intense moments, breathing becomes short and fast, sometimes all the way to hyperventilation: CO2 drops, dizziness, tingling and the feeling of losing control appear, and the brain reads it all as danger and amplifies the reaction. The exhale guided through the pendant interrupts exactly this loop: breathing rebalances, and the vagus nerve sends the safety signal.
The object is always in the same place, around your neck, so your hand knows the way even when your mind is overwhelmed. For recurring panic attacks or diagnosed anxiety, use it as support alongside a specialist, never instead of one.
First lessons in calm for children
Children learn emotional regulation through play, and the pendant turns breathing into a game: we blow slowly to cool down soup, we inflate an invisible balloon. A few long exhales together with a parent, in the evening or after a moment of anger, become their first tool for calming down, a skill for life.
Used under adult supervision, cleaned beforehand, as a moment you share, never as an obligation.

Three steps, under a minute, impossible to get wrong
You can breathe slowly without any tool, just as you can exercise without a gym. The difference shows in real moments: under stress, the exhale shortens by itself, counting becomes impossible, and the technique stays theory. The calibrated channel takes over the hard part, and the object around your neck turns the technique into a habit you actually keep.
Raise it to your lips
Discreetly, with two fingers, exactly as in the photos. From its place around your neck, the gesture takes a second.
Breathe in through the nose
A normal, calm inhale through the nose. No special rules and no effort.
Breathe out through the pendant
Slowly, until your lungs are empty: the channel makes the exhale long and steady for you, no timer and no counting. A few cycles, under a minute in total.
Under 1 minute · Completely silentProtocols by goal, from quick reset to ritual
The same principle throughout, an exhale longer than the inhale; what changes is the moment, the duration and the rhythm. Choose the one that fits your life.
In the evening, before sleep
Put your phone face down, turn off the light and do 2-3 minutes of long exhales through the pendant. Slow breathing is associated with a lower heart rate and the natural transition into rest. The last thing of the day becomes an exhale, instead of a screen.
Quitting smoking and vaping
A nicotine craving comes bundled with a gesture: hand to lips. CALM One keeps the gesture and changes the content: you breathe in calm instead of smoke, at every craving. For severe dependence, combine the tool with your doctor's support.
Before presentations, meetings and exams
In the hallway, in the lift or at your desk, discreetly take 3 long exhales through the pendant. A slowed breathing rhythm is associated with a state of alert calm: relaxed enough to think clearly, present enough to perform.
Guided techniques: 4-7-8, cyclic sighing and more
CALM One naturally guides the most studied extended-exhale techniques, from the classic 4-7-8 to cyclic sighing, the protocol with the best results in the 2023 Stanford study. The air channel keeps the right rhythm for you, no timer and no counting, and the step-by-step guide to each technique comes with the product.
The daytime micro-calm ritual
Three one-minute breaks, sprinkled through the day. Regular micro-breaks build a more stable nervous system over time, and the pendant around your neck reminds you of them by itself.

Reviews from real customers
Clear answers, before you order
What is a breathing pendant and how does it help me when I feel nervous or stressed?
A breathing pendant is a wearable breathwork tool: a steel tube with a calibrated air channel through which you exhale slowly. The extended exhale is associated with activation of the vagus nerve and the parasympathetic system, the body's natural calming response. CALM One from NeuroGenesis DNA turns a proven technique into a simple gesture, always around your neck.
What happens in my body and brain when I use it?
A slow exhale increases vagus nerve activity, and the body switches from alert into calm and recovery: the pulse drops, muscle tension releases, and the prefrontal cortex, the part of the brain responsible for decisions, memory and clarity, regains the resources that stress had seized. Studies link an exhale longer than the inhale to increased parasympathetic activity measured through heart rate variability, and the pendant's air channel produces this type of exhale automatically, every time.
Can you hear it when I exhale through it? Can I use it at the office without anyone noticing?
In normal use, CALM One is completely silent: the air passes slowly through the channel, with no whistling. From the outside it looks like you are bringing a piece of jewellery to your lips for a moment, so it works in meetings, in traffic, in queues, anywhere.
Can it help me quit smoking or vaping?
This is one of the most popular uses of the tool worldwide. A nicotine craving comes with a deeply rooted gesture: hand to lips, inhale, exhale. The pendant keeps the ritual and replaces the content: you breathe in calm instead of smoke, at every craving. For severe dependence, combine the tool with your doctor's support.
Does it help with anxiety or when I feel a panic attack coming?
Many NeuroGenesis DNA customers use it precisely as an anchor for anxious moments: instead of fighting your thoughts, you act directly on your physiology. The slow exhale interrupts the hyperventilation spiral and sends the safety signal through the vagus nerve, and the physical object around your neck gives an overwhelmed mind a concrete point of support. For diagnosed anxiety or recurring panic attacks, use it alongside a psychotherapist or doctor, who remain the foundation of treatment.
How is CALM One connected to mental biohacking and longevity?
Chronic stress is one of the great accelerators of ageing: high cortisol, inflammation, fragmented sleep and low vagal tone, exactly the marker tracked in longevity through heart rate variability. CALM One is the mental biohacking tool in the NeuroGenesis DNA Mind Performance line: every stress moment stopped in time is a real physiological switch, and the switches compound over the years, like physical training or quality sleep.
Can I use it with my child?
Yes, it is an excellent tool for teaching children emotional regulation as a game, together with a parent, in the evening or after moments of anger. Details are in the children's protocol on this page; we recommend adult supervision and cleaning the pendant beforehand.
How long do I need to use it to feel the effect?
In the moment: a few long exhales take under a minute, and slowing the breath acts quickly on heart rate. Long term: in the Stanford study, 5 minutes a day for a month were associated with a steady improvement in mood and reduced anxiety, with the effect growing from week to week. Consistency beats intensity.
Are there studies supporting the technique?
Yes, slow breathing with an extended exhale is among the most studied stress-regulation techniques: the randomised Stanford study published in Cell Reports Medicine in 2023, a Nature Scientific Reports meta-analysis of 12 trials and meta-analyses dedicated to heart rate variability all point the same way. All sources, with links, are in the studies section on this page.
What material is it made of? Does it discolour over time?
The pendant and chain are made of 304 stainless steel, a hypoallergenic material used in the food and medical industries. It keeps its colour and finish through daily wear, sweat and contact with water, unlike cheap alloys that discolour and can stain the skin.
How do I care for it? Can I shower and exercise with it?
Cleaning takes a few seconds: warm water and soap, rinse, dry. 304 stainless steel withstands water, sweat and intensive use, so you can wear it in the shower, at the gym and every day; after salt or chlorinated water, a quick rinse keeps its finish.
Is it a medical device?
CALM One is a wellness tool that guides a breathing technique, with no substances, no electronics and no claims of treatment. For diagnosed anxiety, recurring panic attacks or any medical condition, talk to your doctor or a psychotherapist: the pendant can accompany a professional plan very well, but it does not replace it.
Why buy it from NeuroGenesis DNA, and what if I am not satisfied?

What science says about calming breath
The reference studies on the extended exhale, slow breathing and breathwork, each with a link to the original source. They concern the techniques that CALM One guides; the tool remains a wellness product, with no medical claims.
Study on healthy adults: increasing the exhale-to-inhale ratio raised high-frequency heart rate variability, the marker of parasympathetic activity. Exactly the principle behind the pendant's air channel.
