Andrew Huberman, Ph.D.: How to Use Nervous System Tools Before High-Stakes Events

 The moments before a big presentation, a competitive match, a difficult conversation, or even a first date can feel physically brutal. Your heart pounds, your palms sweat, your thoughts race, and despite knowing the material cold, you suddenly feel like a deer frozen in headlights. Andrew Huberman, who has coached everyone from professional athletes to opera singers on performance anxiety, argues that this response is not a flaw in your design—it is simply your nervous system preparing for a threat that does not exist. The good news is that you can speak directly to that ancient system using specific, science-backed tools. These are not vague relaxation techniques. They are precise neurological levers that shift your body from panic mode to performance mode in minutes, sometimes seconds.

The Double Inhale That Instantly Lowers Heart Rate

When your heart is racing before a high-stakes event, the worst thing you can do is take a single, deep, dramatic breath. Huberman explains that a long, slow exhale does lower heart rate, but a single deep inhale actually accelerates it further. The solution is a specific breathing pattern he calls the physiological sigh. You take a deep breath in through your nose, then before exhaling, you take a second, shorter sip of air on top of the first. Then you exhale slowly and completely through your mouth. That double inhale fully expands the tiny alveolar sacs in your lungs, many of which collapse under stress. When those sacs open, your diaphragm sends a powerful signal through your vagus nerve telling your heart to slow down. Huberman recommends doing two or three physiological sighs in the five minutes before any high-stakes event. Unlike meditation or other longer practices, this works within about thirty seconds and lowers your heart rate by ten to twenty beats per minute reliably.

The Five-Minute Optic Flow Calming Sequence

Here is a tool Huberman uses with competitive shooters and surgeons who need steady hands under pressure. Your brain’s anxiety centers are directly calmed by a specific visual experience called optic flow, which happens when objects move past you from the center of your vision toward the periphery. Before a high-stakes event, Huberman recommends five minutes of slow walking while allowing your gaze to relax softly, not locking onto any single object. This pattern of continuous, predictable motion across your visual field triggers a release of GABA, your brain’s primary calming neurotransmitter. If you cannot walk before your event—perhaps you are waiting backstage or sitting in your car—you can generate the same effect by slowly moving your head from side to side while keeping your eyes relaxed, or even by watching a short video of smooth, forward-moving scenery. The key is avoiding sudden shifts or rapid saccades, which activate alertness rather than calm.

Why Cold Exposure Before Stress Works Backward

Most people assume that if they are already anxious, the last thing they need is a shock of cold water. Huberman turns this assumption on its head. Deliberate cold exposure to the face and neck, for about thirty to sixty seconds, actually reduces the physiological response to subsequent stressors. Here is the mechanism: cold activates your sympathetic nervous system—the same system that fires during anxiety. But when you voluntarily expose yourself to cold, your brain learns that this high-arousal state is safe and under your control. The next time your sympathetic nervous system activates during a real stressor, your brain does not panic because it recognizes the feeling. Huberman recommends doing a cold face plunge or cold shower thirty to sixty minutes before a high-stakes event. The effect is not immediate calm. The effect is stress inoculation. You feel the cold, your heart rate spikes, you breathe heavily, and then you recover. That recovery trains your nervous system to move through arousal rather than getting stuck in it.

The Gaze Anchor That Steadies the Mind

When people feel nervous before a performance, their eyes tend to behave in one of two unhelpful ways. Either they fixate rigidly on a single point, which increases mental rigidity, or they dart anxiously around the room, which hyperactivates threat-detection circuits. Huberman offers a middle path called the gaze anchor. You choose a single point in your environment—a spot on the wall, the knot of someone’s tie, a logo on the podium—and you rest your gaze there, not staring rigidly but softly, allowing your peripheral vision to remain open and relaxed. This gentle anchoring tells your brain that you are in a stable, predictable environment with no immediate physical threat. Your prefrontal cortex, which handles complex decision-making, can then stay online instead of being hijacked by your amygdala’s panic signals. Huberman suggests finding your gaze anchor ten seconds before you begin speaking or performing, and returning to it during any moment of hesitation or forgetfulness.

The Toe-Twitch Trick for Reducing Physical Tension

Here is a subtle tool that Huberman learned from observing elite military snipers. When you are anxious, your body prepares for fight or flight by tensing large muscle groups—your shoulders, your jaw, your legs. That tension feeds back to your brain, telling it that danger is present. But you cannot always stretch or shake out your entire body before a formal event without looking strange. The solution is to focus on a single, small muscle group that no one can see you move. Huberman recommends subtly twitching your toes inside your shoes, alternating between curling and relaxing them. This small movement activates the same neural pathways that govern larger muscle relaxation. As your toes relax, signals travel up your spinal cord telling your larger muscle groups to follow suit. Within about ninety seconds of focused toe twitching, most people feel a noticeable drop in shoulder and jaw tension. It sounds ridiculous, Huberman admits, but it works because your brain does not distinguish between small and large muscle commands when it comes to relaxation.

The Counting Backward Protocol for Resetting Working Memory

One of the cruelest tricks of performance anxiety is that it often causes you to forget what you were going to say or do next. Huberman explains that anxiety floods your working memory—the mental scratchpad where you hold information in real time—with intrusive self-referential thoughts like “I’m going to mess this up.” Those thoughts displace the actual content you need. His reset protocol is simple but specific. When you feel your mind going blank, stop trying to force the original information back in. Instead, count backward from one hundred by intervals of three—one hundred, ninety-seven, ninety-four, and so on. This task is just demanding enough to clear your working memory without being overwhelming. After about thirty seconds of this, your working memory resets, and the original information often returns spontaneously. Huberman has used this with opera singers who forgot lyrics mid-performance and with executives who lost their train of thought during board presentations. The counting does not need to be accurate. The process of shifting mental gears is what matters.

The Post-Event Cool-Down That Prevents Future Anxiety

Finally, Huberman emphasizes that how you behave after a high-stakes event directly shapes your nervous system’s response before the next one. Many people immediately grab their phones, replay every mistake in their heads, or seek validation from others. This reinforces the neural pathways of anxiety. Instead, Huberman recommends a ten-minute cool-down period immediately after the event, during which you deliberately slow your breathing, relax your gaze into peripheral vision, and sit or lie still. This post-event quiet state tells your nervous system that the event is over and that you survived without needing to analyze or panic. Over time, this practice reduces the anticipatory anxiety before future events because your brain learns that high-stakes moments end in safety rather than in rumination. Huberman calls this “closing the loop” on the stress response, and he considers it just as important as any pre-event tool you use.
