In November 2025, I tested two different sleep interventions (mouth taping and nose strips) against a couple of variables on a single subject (myself).
Did the 30 minutes deep sleep reduction also reduce total sleep duration? Or did it simply shift to light sleep/other sleep modes? Because a 30 minute sleep reduction without side effects would be awesome. Those are hard to come by.
No, sleep duration not statistically different; iirc it looked like a slight increase in light sleep. It's a small study so who knows.
Thinking from first principles says mouth tape is a red herring and that nasal strips are the thing that should increase airflow and thus the overall quality of sleep. I want to do a proper nasal strip study but they keep detaching if I do any skincare at all. On the todo list to fix that.

Too bad on the duration but that's expected. Putting the nasal strip stuff on my TODO list as well I guess.
