Pulsetto - Your Peace & Better Sleep Partner

The Science Behind Vagus Nerve Stimulation

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.

• Boosted Heart Rate Variability (HRV): This device helps improve HRV, an important marker of heart health and resilience to stress.

• 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.

What's Included:

• Pulsetto Vagus Nerve Stimulation Device

• USB-C Charging Cable

• Electrode Gel (enough for one month of use)

• User Manual

• Free Premium App Trial (includes 11 guided meditations, 54 breathing exercises, and 1,200 positive affirmations)

How Pulsetto Works:

Using Pulsetto is simple and takes just 4 minutes to start feeling the effects. Here's how it works:

1. Apply a generous amount of gel to your neck or directly onto the electrodes.

2. Place the device on your neck.

3. Pair it with the Pulsetto app on your smartphone.

4. 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.

Bryan Johnson: Pro Biohacker’s Evening Routine

Bryan Johnson is well known for his Blueprint protocol, with more than 200 daily health steps. Yet, his evening routine is surprisingly simple and rooted in science. Every night, he goes to bed at exactly 8:30 PM, a strict schedule that keeps his circadian rhythm aligned and ensures he wakes up rested.

Key elements of Bryan Johnson’s sleep routine:

• Consistent bedtime: 8:30 PM sharp, every night.
  
  

• Darkened room: blackout environment to support melatonin production.
  
  

• Temperature-controlled mattress: keeps the body cool for deeper sleep.
  
  

• Non-invasive vagus nerve stimulation: a short session before sleep, and sometimes if he wakes during the night, to calm the nervous system.
  
  

• Sleep supplements: Melatonin plays a role in his regimen.
  
  

• Optimized pillow setup: designed for neck support and circulation.
  
  

Bryan has shared that when nighttime anxiety disrupts his rest, gentle vagus nerve stimulation helps him settle back to sleep quickly. His methodical approach, supported by tools like Pulsetto, highlights that consistency, not complexity, is the real key to restorative sleep.
