Stripped of the product placement ("comment 'link' to buy it"), the contraindication list is the checkable, useful part of this post. Recent reviews of nocturnal mouth-taping (American Journal of Otolaryngology, 2025; PLOS ONE, 2025, 10 studies, 213 patients) confirm the practice carries a real risk when nasal obstruction hasn't been ruled out — up to the asphyxiation risk flagged by the PLOS ONE review — and that most measured benefits (snoring, apnea-hypopnea index) show up only in specific subgroups, mainly people with mild, already-identified and monitored sleep apnea. The caution in this post (don't try it without ruling these out first) lines up with what those reviews show, even though the general benefit of mouth taping for "better sleep" is itself weak and inconsistent in the same literature. The safety guidance holds up; the implied benefit of the product being sold still has to be shown.
