A Maryland sports medicine doctor warns against the trending practice of mouth taping for improved sleep and athletic performance. While the theory suggests nose breathing is more efficient, Dr. Gourdin cites a lack of strong evidence and potential dangers. Risks include restricted breathing, reduced oxygen levels, and anxiety attacks, especially for those with sleep apnea or nasal issues. The doctor recommends alternative sleep improvement methods like a calming bedtime routine and limiting screen time.
