Life Cykel Mouth Tape is designed to gently encourage nasal breathing during sleep by keeping the lips closed overnight. Mouth breathing at night can disrupt sleep architecture, reducing time spent in deep sleep and REM cycles where muscle repair and hormone optimisation occur. By supporting nasal breathing, this tape helps you make the most of every minute of rest. Applied to clean, dry lips before bed, the tape is gentle and non-intrusive. Those new to mouth taping are advised to practise during the day for 10–15 minutes to become comfortable. Nasal breathing supports nitric oxide production, improved oxygen delivery, and the maintenance of deeper sleep stages.
