Andrew Huberman, a well-known science communicator, has discussed why a small group of people seem to avoid hangovers entirely, suggesting the difference may come down to genetics rather than luck or personal resilience. The central idea is that alcohol is processed in the body through chemical pathways that determine how strongly someone feels sedation, impaired coordination, and the unpleasant aftereffects the next day.
According to the discussion, about 8% of people carry a gene variant that changes how their bodies handle alcohol. Instead of alcohol primarily leading to the typical “sedation” or slowdown effect that many people experience, this genetic variation is linked with a different internal response—specifically turning alcohol into a pattern associated with dopamine and an energy surge. Dopamine is commonly associated with motivation, alertness, and reward, which can explain why these individuals may feel more awake and energized after drinking rather than drowsy.
The consequence of this altered biological response is that some people appear to stay functional and even unusually active while others begin to lose inhibitions, slur words, and struggle with basic tasks. In the story’s description, the contrast is vivid: while most people may become very impaired or effectively “black out” during heavy drinking, a smaller fraction remain relatively alert, still moving around and getting things done. The point being emphasized is not just that they have fewer symptoms later, but that their drinking experience itself can feel dramatically different in-the-moment.
The narrative frames this difference as a genetic mechanism that affects the way alcohol interacts with brain chemistry. By steering the body toward a dopamine-linked response and an energy boost, the gene variant may reduce the typical mismatch between how alcohol affects the nervous system and how a person later experiences the recovery symptoms associated with hangovers.
In practical terms, this could mean those individuals continue to feel awake into the early morning hours. The story uses a relatable late-night picture to underscore the idea: they may still be “buzzing” around 3 AM and able to perform routine activities—like doing laundry—while their peers are overwhelmed by intoxication and lack of awareness.
It’s important to interpret the claim carefully. Having a gene variant that shifts alcohol’s effects does not necessarily mean alcohol has no risks. Even if someone feels more awake after drinking, alcohol still affects judgment, reaction time, coordination, and long-term health outcomes. The story’s focus is specifically on the hangover experience and the immediate feeling of sedation versus alertness.
Still, the genetics-based explanation provides a clearer reason for why some people can drink and feel fine, while others feel terrible after even moderate amounts. In the mainstream discussion of alcohol tolerance, people often attribute hangovers to hydration, sleep, or drink type. Huberman’s argument, as described in the text, adds a biological layer: if your body processes alcohol in a way that shifts brain signaling toward dopamine and energy, you may not experience the same sedating pattern that leads many people into stronger intoxication and more severe next-day symptoms.
This genetic framing also helps explain why hangovers can be inconsistent across individuals—especially among friends who drink the same drinks at similar rates but report very different outcomes. If only a minority population has the relevant gene variant, then it makes sense that most people would not share the “no hangover” effect, while a small percentage might repeatedly notice they feel relatively normal after drinking.
Overall, the story conveys a simple takeaway: hangovers are not purely a matter of willpower or bad habits. For around 8% of people, a specific gene variant may alter alcohol metabolism and brain chemistry, producing a dopamine-linked surge and keeping them more awake rather than sedated. That biological difference can make it seem as if they are “immune” to hangovers—staying active at night while others are left incapacitated. Source: Source
Camus: Andrew Huberman explained why some people never get hangovers. About 8% of people have a gene variant that turns alcohol into a dopamine and energy surge instead of sedation. These are the ones still buzzing at 3 AM, doing laundry, while everyone else is blacked out on the. #breaking
