How Athletes Activate the Vagus Nerve to Perform Under Pressure | Featuring Dr. Nick Hoolest | Podcast #477

📋 EPISODE SUMMARY

Dr. Justin Marchegiani sits down with biomedical engineer and competitive golfer-turned-innovator Dr. Nick Hoolest to unpack the science of vagus nerve activation, performance anxiety, and nervous system optimization — exploring how breathing protocols, visualization techniques, and electrical vagal nerve stimulation can help athletes and high performers access calm, focused states on demand. From coherent breathing and forced exhale techniques to the multi-mode VeRelief Prime device, this episode offers practical, research-backed strategies for managing the fight-or-flight response and building a more resilient autonomic nervous system.

🔑 KEY HIGHLIGHTS

• Vagus nerve activation is the central lever for shifting the nervous system out of fight-or-flight (sympathetic) and into a calm, focused parasympathetic state — and can be approached through breathing, visualization, and electrical stimulation depending on what the situation allows
• Coherent breathing — inhaling for 5 seconds and exhaling for 5 seconds at approximately six breaths per minute — is one of the most effective techniques for optimizing heart rate variability (HRV) and priming the nervous system before a performance, competition, or high-pressure event
• A 15-second forced exhale with pursed lips is Dr. Nick Hoolest's top technique for rapidly lowering heart rate and increasing athletic “feel” — the unquantifiable sense of being in the zone that elite performers describe; this technique mimics a mild Valsalva maneuver and triggers an immediate, measurable vagal response
• Visualization works because the nervous system cannot distinguish between vividly imagined experience and real experience — giving the brain consistent mental “reps” in high-pressure scenarios builds true adaptability so that when the real moment arrives, it feels familiar and manageable
• Electrical stimulation of the auricular vagus nerve — the nerve cluster located just behind and beneath the ear — produces measurable drops in heart rate within 60 seconds and improvements in HRV after 10 minutes, with effects reported to be roughly ten times stronger than standard ear-clip stimulators
• The VeRelief Prime device by Hoolest features five stimulation modes: Mode 1 (8 Hz — general state anxiety and median nerve/nausea support), Mode 2 (25 Hz — trigeminal nerve and headache support), and Modes 4 and 5 (coherent breathing sync and 15-second exhale sync for advanced performance and nervous system reset applications)
• Post-error recovery — resetting the nervous system quickly after a mistake in the middle of a competition or performance — is an emerging area of sports performance science, and vagal nerve stimulation may offer a practical, on-the-go solution where traditional meditation is not feasible
• Anecdotally, the device is reported by customers to be particularly supportive for those managing stress-related nervous system dysregulation — by helping users re-engage with environments that previously felt overwhelming, it may support a return to normal daily functioning
• Muscle tension is the factor most correlated with athletic feel — when tension is high, precision drops; combining vagal nerve stimulation with the forced exhale breathing technique may significantly reduce muscle tension in just minutes
• Median nerve stimulation at the wrist using Mode 1 (8 Hz) is noted as potentially supportive for nausea, with anecdotal reports from a range of users — always explore in consultation with a qualified healthcare provider
• Vagal nerve stimulation works best on a healthy foundation — diet, sleep, and lifestyle still matter; individuals with severely dysregulated nervous systems should begin with basic breathing protocols and the device's lowest intensity setting before progressing
