The Big Taping Truth Trial is an ongoing decentralized study investigating whether mouth taping actually works! Participants connect their Oura, Whoop, or Apple watch data and follow randomized taping assignments for 30 nights. The study is ongoing and seeking participants.
It is quite interesting so far, with some people reporting improvements from mouth taping, while others experience the opposite.
For example, this chart from the live results dashboard includes 22 participants who have completed at least 5 nights of each treatment. The average population effect is +0.022 sleep rating points from vertical (almost no difference), but this average includes 4 people with a strong positive effect and 5 people with strong negative effects (the steeper diagonal lines on the plot).
If you’d like to figure out which camp you’d fall in, you can join the study here! At the end they send you a personalized report with your results!
