Tried it. Didn’t work. Why?
A product that worked for someone else can do nothing for you. That usually has a reason.
It worked on the wrong spot
Snoring can start in the nose, the soft palate or behind the tongue. A nasal strip only reaches the nose. If your snoring starts further back, opening the nose may change little.
The evidence measured something else
“Easier breathing” and “less snoring” are different results. Two 2019 trials of a nasal strip in people with a blocked nose found no sleep benefit over placebo strips. A 2015 trial found no change in lab-measured snoring with nasal strips plus breathing exercises.
It was about different people, or a different product
A study in people with sleep apnoea, or of another brand, doesn’t tell you how one product works for simple snoring.
Fit and adjustment
Internal dilators come in sizes. Mouthpieces often need gradual adjustment and a few weeks of getting used to. Check the instructions before calling it a failure.
Something else is going on
Sleep apnoea, a long-term nasal problem, evening alcohol or sleeping on your back can all outweigh a device.
Record a week of nights, write down what actually changed, and consider an assessment. It may save the cost of the next box.
Original sources & their limits
- Report on two placebo-controlled nasal-strip trials (AJMC, on Advances in Therapy 2019) ↗
News report read. Two manufacturer-funded trials (140 and 130 adults with chronic night-time nasal congestion, 14 days). Strips did not improve sleep problems more than placebo strips. They measured sleep in congested people, not snoring.
- Mouth and throat exercises for snoring: randomised trial (Chest, 2015) ↗
Trial record read. 39 people with primary snoring or mild-to-moderate sleep apnoea, three months. Exercises reduced snoring measured in a sleep lab. The comparison group used nasal strips plus breathing exercises and showed no significant change.
- Nasal dilators for sleep apnoea: systematic review (2016) ↗
Read. 14 studies, 147 people with sleep apnoea. No significant change in breathing events, oxygen levels or snoring index. Small, varied studies.
- S3-Leitlinie: Diagnostik und Therapie des Schnarchens des Erwachsenen (AWMF, 2019) ↗
