Haaland is arguably the most famous mouth taper in the world. On the Impaulsive podcast with Logan Paul and KSI, the Manchester City striker revealed that he tapes his mouth shut every night to ensure nasal breathing during sleep. He also uses mouth tape during training sessions as an endurance tool, forcing his body to perform on nasal breathing alone. In his record-breaking 2022–23 season — 52 goals across all competitions, a Premier League title, a Champions League title, and an FA Cup — Haaland credited sleep as the foundation of his performance. His nighttime routine includes blue-blocking glasses, eliminating electronic signals from the bedroom, and mouth tape.

Świątek does not just use mouth tape for sleep — she trains with it. Her fitness coach Maciej Ryszczuk introduced the practice as a way to build endurance by restricting breathing to the nasal pathway during high-intensity on-court drills. Speaking to media before her tournament in Montreal, Świątek explained that nasal breathing makes her heart rate climb faster and makes everything on court harder — which is exactly the training adaptation she is chasing. By the time she removes the tape for a match, her aerobic capacity has been pushed beyond what normal training would achieve.

O'Malley holds the record for most significant strikes landed in a bantamweight title fight. He has spoken publicly about using nasal breathing and mouth taping as part of his conditioning and recovery protocol. For a fighter, the ability to regulate heart rate, conserve energy, and stay calm under pressure is the difference between winning and losing. Nasal breathing activates the parasympathetic nervous system — the rest-and-recover branch — which helps O'Malley maintain composure during five-round championship fights. Mouth taping at night ensures that recovery between training sessions is as efficient as possible.

McCormick made headlines in 2025 when he taped his mouth shut during a tournament round — not just for sleep, but during live competition. After months of struggling with frustration and anger on the course, he used mouth tape as a tool to control his breathing, manage his emotions, and stay focused. He joked that it made him feel like Bane from Batman and that he had to use hand signals to communicate with his caddie. McCormick's experiment shows a different application of mouth taping — not just recovery, but real-time emotional regulation under pressure.

Burgess uses mouth tape to keep his airways clear and train his body to breathe through the nose during sleep. In motorsport, where concentration and reaction time are measured in fractions of a second, recovery quality directly translates to performance behind the wheel. Burgess has credited nasal breathing with fewer injuries, sharper concentration, and more energy on race day, calling it "a huge turning point" for both his performance and his mental wellness.

Huberman is probably the single most influential voice in mouth taping's rise to the mainstream. On his Huberman Lab podcast — one of the most listened-to science podcasts in the world — he has repeatedly discussed how mouth breathing during sleep is "actually dangerous" and associated with sleep apnea, cardiovascular issues, hormonal disruption, and impaired cognitive function. Huberman uses mouth tape as part of his own comprehensive sleep toolkit. In his episode "Sleep Toolkit: Tools for Optimizing Sleep & Sleep-Wake Timing," he laid out the case for nasal breathing as one of the simplest, lowest-cost interventions for improving sleep quality. He also wrote on LinkedIn that mouth breathing is linked to "impaired craniofacial development in kids, and aesthetics and tooth and gut health in adults."

Nestor's book Breath has sold over two million copies worldwide and is one of the most cited books in the mouth taping conversation. In researching the book, Nestor subjected himself to an experiment at Stanford where his nose was plugged for ten days, forcing him to mouth breathe. The results were dramatic: a fourfold increase in sleep apnea events, a 1,300 percent increase in snoring, insomnia, elevated blood pressure, and severely diminished mental clarity. When the plugs were removed and he switched to exclusive nasal breathing, every single metric reversed. His snoring decreased by 4,000 percent, sleep apnea events dropped to zero, and his blood pressure dropped an average of 10 points. Nestor recommends mouth taping during sleep as a simple tool for promoting nasal breathing and has published roughly 500 scientific references supporting the case for nasal breathing on his website.

Paltrow has called mouth tape the "single best wellness tool" she has found recently. For someone who has built an entire brand around evaluating every wellness product on the market, that is a significant endorsement. She credits mouth taping with deeper sleep and improved morning energy — a simple, low-tech tool in a world of complex and expensive wellness interventions.

Fallon brought mouth taping to late-night television after a conversation with Andrew Huberman on the show. He publicly committed to trying it, telling his audience he was going to "tape my mouth shut when I go to sleep and force myself to breathe through my nose." Earlier in the conversation, Fallon told Huberman: "If I could invest money, I would invest in breathing." The segment introduced mouth taping to an audience of millions who had never heard of the practice — and it was delivered with the kind of humor and relatability that makes people actually try something new.

Graham has been open about her mouth taping routine, telling audiences she cannot sleep without it. In a career where showing up rested, recovered, and camera-ready is a professional requirement, that is not a casual endorsement. Her support has been particularly influential among women who may have seen mouth taping as a male-dominated biohacker trend — Graham helped normalize it as a universal sleep tool.

Roberts told Vogue she "can't live without" mouth tape, listing it among her essential daily routines alongside skincare and hydration. Her endorsement on Vogue's Instagram reached a massive audience and positioned mouth taping alongside beauty and self-care — not just performance optimization.

Frankel demonstrated her mouth taping routine on TikTok and credited it with sleeping a solid eight hours for the first time in years. Her video was one of the most-shared pieces of mouth taping content on the platform and brought the practice to an audience that skews older and more mainstream than the typical biohacking community.

Mitchell shared on her Instagram Stories that she started taping her mouth shut during sleep and "never slept better — and even better when I wake up." She added: "Don't knock it till you try it." Her endorsement resonated because it was unscripted and personal — not a paid post, just a genuine recommendation from someone whose career depends on looking and feeling her best.

Mouth taping hit reality TV when Love Is Blind captured Garrett taping his mouth shut every night before bed — with his fiancée Taylor Krause placing the tape for him on camera. The moment went viral and introduced mouth taping to an entirely new demographic. For many viewers, it was the first time they had seen someone actually do it, making the practice feel accessible and normal rather than extreme.
