Who Is Andrew Huberman?

Andrew Huberman, PhD, is a tenured professor of neurobiology and ophthalmology at Stanford University School of Medicine. Huberman researches brain development, neural plasticity, and the effects of behavior and breathing techniques on the nervous system. His published work appears in peer-reviewed journals including Nature and Science.

Huberman reached a wider audience through the Huberman Lab Podcast, where he translates neuroscience discoveries into practical tools. He covers topics like stress mitigation, sleep optimization, and physiological breathing, sharing actionable methods from his research.

You engage with his techniques when exploring neurobiologically validated practices for well-being and resilience. Professionals and self-improvement communities cite Huberman's methods for quick stress reduction and focus improvement.

Understanding the Physiological Breath

Andrew Huberman's physiological breath, also called the "physiological sigh," uses simple breathing patterns to rapidly calm your nervous system. This evidence-based technique supports stress reduction, focus, and overall mental well-being.

What Is the Physiological Sigh?

The physiological sigh involves two quick nasal inhales followed by a slow, controlled exhale through your mouth. Scientists first observed this double inhale and long exhale in mammals during sleep and stress offset (Huberman Lab, 2021). You can use it anytime, as it doesn't require special tools or privacy.

The Science Behind the Breathing Technique

Researchers found that the physiological sigh balances oxygen and carbon dioxide levels in your blood, quickly reducing physiological arousal (Li & Yackle, Nature 2017). The double inhale fully inflates your lungs, maximizing alveolar air exchange, as seen in controlled studies. The long exhale activates your parasympathetic nervous system, which lowers heart rate and dampens stress signaling (Stanford Medicine).

Benefits of the Andrew Huberman Physiological Breath

The Andrew Huberman physiological breath delivers fast, research-driven benefits for your mind and body. Consistent practice enhances daily stress management and strengthens cognitive capabilities.

Stress Reduction and Anxiety Relief

Using the physiological breath reduces acute stress by activating the parasympathetic nervous system. The extended exhale slows your heart rate, lowers blood pressure, and dampens stress hormone levels. In trials, participants experienced measurable decreases in anxiety within one to three breath cycles (Huberman Lab, 2021). Applying this technique during moments of overwhelm—such as after a stressful meeting or during public speaking—restores psychological calm and physical relaxation faster than basic deep breathing exercises.

Enhancing Focus and Mental Clarity

Engaging in the physiological breath improves attention span and mental clarity. The double nasal inhale increases oxygen delivery to the brain, supporting sharper executive function. Research highlights marked improvements in focus in individuals practicing the technique before tests or high-demand work sessions (Stanford University, 2020). Users from athletic and academic environments report faster recovery from distractions and improved task engagement after using the physiological breath, both in short breaks and prolonged periods of concentration.

How to Practice the Physiological Breath

Training with the Andrew Huberman physiological breath only takes a few seconds and no equipment. Use this actionable method as a reset for mental clarity and stress control.

Step-By-Step Guide

• Choose Position: Sit or stand with your spine straight to keep your airway open.
• First Inhale: Breathe in deeply through your nose until your lungs are nearly full.
• Second Inhale: Take a quick, sharp nasal inhale to maximally expand your lungs.
• Full Exhale: Exhale slowly and completely through your mouth, prolonging the breath until you push out all the air.
• Repeat Cycles: Practice 1–3 breath cycles for rapid reduction in stress and increase in focus.

Tips for Consistency and Effectiveness

• Pair with Triggers: Anchor the breath to moments of high stress or transitions, such as before meetings or after intense activity.
• Track Frequency: Use habit trackers or set reminders to build repetition throughout your day.
• Adjust Timing: Start with 1–3 cycles, increasing only if needed, when stress persists.
• Minimize Distractions: Choose quiet environments for practice to maximize neural and physiological benefits.

When Should You Use This Technique?

Apply the Andrew Huberman physiological breath in moments requiring rapid stress relief, focus resets, or emotional regulation. Use this technique:

• During Acute Stress: Practice when experiencing spikes of anxiety, frustration, or overwhelm, such as before public speaking, during work deadlines, or after conflict.
• For Performance Preparation: Integrate before exams, athletic events, or critical tasks that demand immediate composure.
• Between Cognitive Tasks: Reset mental state when switching between demanding projects or after encountering distractions.
• After Physiological Arousal: Employ when heart rate increases or breathing accelerates mid-workout, during arguments, or following startling events.
• To Promote Relaxation: Use to wind down before sleep, meditation, or periods requiring relaxation.

Leverage this evidence-based breathing method during any scenario necessitating swift reduction of physiological arousal or cognitive reset, especially in high-demand environments. Optimize outcomes by maintaining consistent practice and pairing the technique with specific daily triggers.

Frequently Asked Questions

What is the Andrew Huberman physiological breath?

The Andrew Huberman physiological breath, also known as the "physiological sigh," is a quick breathing technique involving two short inhales through the nose followed by a long, slow exhale through the mouth. This method rapidly reduces stress and helps reset focus in seconds.

Who is Dr. Andrew Huberman?

Dr. Andrew Huberman is a tenured professor of neurobiology and ophthalmology at Stanford University School of Medicine. He researches brain development, stress, and the effects of breathing techniques. He also hosts the popular Huberman Lab Podcast.

How does the physiological sigh reduce stress?

The physiological sigh reduces stress by balancing oxygen and carbon dioxide levels in the blood. The double inhale inflates the lungs fully, while the long exhale activates the parasympathetic nervous system, rapidly lowering heart rate and dampening the body’s stress response.

What are the main benefits of the physiological breath?

Benefits include quick stress reduction, lower heart rate and blood pressure, improved mental clarity, and better focus. Many users report feeling calmer and more able to concentrate within a few breath cycles.

How do you perform the physiological breath?

Sit or stand with a straight posture. Take two deep, quick inhales through your nose (the second inhale should be short), then slowly exhale through your mouth. Repeat the cycle as needed for stress relief or enhanced focus.

When should I use the physiological breath technique?

Use the physiological breath during stressful moments, before important tasks, between periods of focus, after physical arousal, or anytime you need rapid relaxation or a mental reset.
