AMA #16: Sleep, Vertigo, TBI, OCD, Tips for Travelers, Gut-Brain Axis & More

Welcome to a special edition of the 16th Ask Me Anything (AMA) episode, part of Huberman Lab Premium, recorded in Sydney, Australia. This episode is a recording of a live stream AMA, originally exclusive to our Premium members. We've decided to make the full-length version available to everyone, including non-members of Huberman Lab Premium. Huberman Lab Premium was launched for two main reasons. First, it was launched in order to raise support for the main Huberman Lab podcast — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation. If you're not yet a member but enjoyed this full-length livestream AMA, we invite you to join Huberman Lab Premium at https://www.hubermanlab.com/premium. By subscribing, you'll gain access to exclusive benefits including our regular monthly full-length AMA episodes, AMA transcripts, podcast episode transcripts, early access to live events and more. Additionally, a significant portion of your membership proceeds contributes to advancing human scientific research. You can learn more about the research we were able to support in our Annual Letter 2023: https://www.hubermanlab.com/annual-letter/2023.

WHAT IT’S REALLY ABOUT

Huberman’s Travel AMA: Sleep Tools, Vertigo Fixes, Brain and Gut Repair

  1. Andrew Huberman answers premium-subscriber questions on maintaining health while traveling, sleep optimization, vertigo, TBI recovery, OCD treatment, circadian rhythm shifting, nutrition (fish oil, creatine), hormone testing, gut–brain axis, and oral/tongue care.
  2. He emphasizes low- or zero-cost tools such as light exposure, movement, NSDR/Yoga Nidra, and fermented foods, and clarifies when higher-tech interventions (TMS, hyperbaric oxygen, hormone labs) make sense.
  3. Throughout, he stresses pragmatism over perfection: focusing on consistent, science-based practices now rather than regretting past mistakes, and tailoring protocols to context and individual variability.
  4. The episode blends actionable how-tos—like a quick vertigo reset, mini jet-lag strategy, and tongue-brushing protocol—with conceptual frameworks such as QQRT for sleep and the vestibulo-ocular reflex for balance.

IDEAS WORTH REMEMBERING

5 ideas

Use a simple ‘quadfecta’ to maintain health and reset circadian rhythm while traveling.

On arrival in a new time zone, prioritize morning sunlight (even through clouds), early-day movement, social engagement, and either caffeine or breakfast (depending on preference). Combine this with dim or red light in the evening and aligning to local meal times. This amplifies the natural morning cortisol and catecholamine pulse to promote daytime alertness and smoother nighttime sleep.

Assess sleep by QQRT (quality, quantity, regularity, timing), not just total hours.

Five to six hours can be adequate if daytime alertness is good and sleep is consolidated. Focus on: (1) quantity you actually get, (2) quality—few awakenings and a sense of physical and emotional restoration, (3) regularity—similar bedtime/waketimes most days, and (4) timing—matching your chronotype (early vs late) and keeping that timing consistent. Add a 10–30 minute NSDR session in the morning or later in the day to recover sleep pressure and train deeper sleep.

Use vision to override vertigo by anchoring the vestibulo-ocular reflex.

If dizziness feels like spinning/falling sideways (vertigo), it likely involves inner-ear (otolith/semicircular canal) dysregulation. To recalibrate, fix your gaze on a stable point several feet away or your fingertip at arm’s length, then slowly move toward your nose until just before crossing your eyes; move back and repeat. This forces visual input to dominate and helps the vestibular system adjust, often reducing motion sickness and vertigo sensations.

You can partially repair past brain insults (poor lifestyle, TBI) by doubling down on fundamentals plus targeted tools.

Huberman advises against obsessing over past diet/sleep mistakes and instead maximizing present neuroplasticity: consistent high-quality sleep for glymphatic clearance, possibly sleeping with feet elevated 5–15 degrees, considering hyperbaric oxygen therapy post-TBI if available, and using 5–10 g/day creatine monohydrate to support forebrain energy metabolism (while monitoring hair/DHT if concerned). Avoid overdoing anti-inflammatory supplements like high-dose curcumin due to side effects and contamination risk.

Treat OCD as a circuit-level plasticity problem that needs both drugs and behavior.

OCD likely involves miswiring of basal ganglia go/no-go circuits and their coupling to dopamine-based reward. The compulsion paradoxically intensifies the obsession instead of relieving it. Effective treatment often combines SSRIs or other neuromodulator-based drugs to open a ‘plasticity window’ with structured behavioral work: exposure to triggers, resisting or replacing compulsions with therapist support, and possibly adding TMS. The medication isn’t “fixing serotonin” per se; it’s enabling network rewiring.

WORDS WORTH SAVING

5 quotes

The protocols of the Huberman Lab Podcast are designed to mesh with the rest of life, not to replace it.

Andrew Huberman

Insomnia is excessive daytime sleepiness due to lack of sleep at night.

Andrew Huberman

With OCD, the compulsion does not remove the obsession; it exacerbates it.

Andrew Huberman

Biological systems are very robust. You can overcome years, decades of poor use or misuse of those systems.

Andrew Huberman

More important than training hard is to not get hurt, because if you get hurt, you can’t train.
