The Power of the Vagus Nerve

The vagus nerve is your body’s main pathway for switching into “rest and digest” mode. When activated, it lowers heart rate, reduces anxiety, and signals safety to the brain. Strengthening vagal tone is one of the fastest ways to calm a restless mind at night.

Tools Neuroscientists Recommend (Andrew Huberman, Stanford)

Long Exhales

Making your exhale longer than your inhale directly calms the nervous system. Try inhaling for 4 seconds, then exhaling for 8 seconds. Repeat for a few minutes to lower heart rate and prepare for sleep.

Gentle Eye Movements

Moving your eyes slowly from side to side helps reduce hyperarousal and quiets mental chatter. Huberman notes this mimics natural eye patterns that signal safety.

Humming or Chanting

The vibration stimulates the vagus nerve through the vocal cords, helping lower stress levels. Even a soft hum can create a calming effect before bed.

Neck Stretching

Gentle lengthening and tilting of the neck muscles relaxes tension where the vagus nerve passes. Combine with slow breathing for deeper calm.

Why This Works for Sleep

Each of these practices activates the parasympathetic nervous system your body’s built-in brake pedal. By lowering cortisol and slowing heart rate, you create the ideal environment for melatonin release and natural sleep onset.

How to Use These Tonight

• Set aside 5–10 minutes before bed.
• Dim the lights, sit comfortably, and try a combination of these techniques.
• Pair them with a calming ritual like journaling or gentle yoga to deepen the effect.
