If you’ve been searching for natural ways to reduce stress, improve sleep, and boost your overall wellness, vagus nerve stimulation (VNS) devices are gaining popularity worldwide, including here in Hong Kong. These devices use gentle electrical impulses to stimulate the vagus nerve, a critical nerve that influences heart rate, digestion, mood, and relaxation.
What Is Vagus Nerve Stimulation and Why Does It Matter?
The vagus nerve is the longest cranial nerve in the body, running from the brainstem to various organs. It plays a key role in regulating the parasympathetic nervous system, often called the “rest and digest” system. Stimulating this nerve can:
Pulsetto is a wearable device that uses vagus nerve stimulation (VNS) to promote relaxation and reduce stress and anxiety. By targeting the vagus nerve with gentle electrical impulses, Pulsetto can help induce a state of calm, making it easier to fall asleep and stay asleep.
Advantages of Pulsetto:
Stress Reduction: Experience significant relief from daily stress by activating your vagus nerve and shifting your body into a "rest and digest" state.
Improved Sleep: Pulsetto supports restful sleep by calming your nervous system, helping you wake up refreshed and energized.
Enhanced Mental Clarity: By promoting relaxation, Pulsetto aids in sharpening focus and reducing brain fog.
Digestive Health Support: Vagus nerve stimulation positively impacts the gut-brain connection, aiding digestion and reducing bloating.
Chronic Health Support: Pulsetto offers support for individuals managing chronic stress, anxiety, and fatigue, helping to improve their quality of life.
Using Pulsetto is simple and takes just 4 minutes to start feeling the effects. Here's how it works:
Apply a generous amount of gel to your neck.
Place the device on your neck.
Pair it with the Pulsetto app on your smartphone.
Choose your desired program and start the device through the app.
The device creates a gentle, pleasant vibration or tingling sensation in your neck area. This stimulation helps activate your parasympathetic nervous system, leading to a calmer, less stressed state.
