This week, Matt examines the viral trend of mouth taping, a practice touted as a remedy for snoring and sleep apnea. He explains the core theory, which centers on promoting the benefits of nasal over mouth breathing, before critically assessing whether this popular ritual is a scientifically sound solution or a risky trend whose dangers are lost amidst the online hype.

Matt navigates the scientific evidence, revealing a cautionary tale: while preliminary data suggests a potential benefit for a select group with mild obstructive sleep apnea, he sounds a marked alarm for those with moderate to severe conditions. For this latter group, mouth taping can be dangerous, potentially worsening airway obstruction by blocking a necessary escape valve for air. Our host also warns that you must never tape an infant or young child's mouth, and to always skip taping if you have a cold or severe allergies. He concludes that for most, the practice is unproven with unknown long-term safety, and the hype has far outpaced the data, making a cautious approach and professional medical consultation essential.
