Proof: Mouth taping during sleep greatly improves sleep quality and reduces sleep apnea.
Generated: 2026-04-01

Claim analysis: Compound causal claim with two assertions joined by AND.
Both "improves" and "reduces" use causal language requiring SC-association +
SC-causation decomposition per proof-engine hardening rules. Structured as a
compound claim with two sub-claims:
  SC1: "Mouth taping greatly improves sleep quality"
  SC2: "Mouth taping reduces sleep apnea (AHI)"
