Blocked nose at night (nasal obstruction)

Most of the blockage sits at the nasal valve, a narrow slit just inside the nostrils between the soft side wall, the septum and the lower turbinate. It is "the bottleneck of the nose" and causes almost half of its resistance to airflow. Air speeds up through the slit, pressure drops, and a soft side wall gets sucked inward on each breath in (Bloching 2008).

Typical signs: mouth breathing at night, snoring, waking with a dry mouth or sore throat, and nostrils that cave in on a normal breath in.

In a study of 4,927 adults, a stuffy nose on 5 or more nights a month went with snoring most nights, daytime sleepiness and waking unrefreshed. Allergy-related congestion carried 1.8 times the odds of moderate to severe breathing problems in sleep (Young 1997).

Five items, each rated 0 (no problem) to 4 (severe) for the past month; add them up and multiply by 5 (NOSE scale, AAO-HNS). It takes the patient 30 seconds, and the patient view carries it as a self-check.

5 to 25 is mild, 30 to 50 moderate, 55 to 75 severe and 80 to 100 extreme (BackTable). Score again after two weeks of whatever you try.

Anything that swells the lining or narrows the frame shrinks the valve, and the clue usually tells you which.

Put what the patient feels next to what the nose shows, because the two often disagree (Yepes-Nuñez 2013). That means the history and NOSE score, a look inside the nose with the cheek-pull (Cottle) test, and if needed a sniff-flow test, a camera exam (nasal endoscopy) or allergy tests (Ottaviano 2019; West Suffolk NHS; NHS North West Allergy Network). A sleep study is needed when snoring comes with pauses or gasping (NHS).

Leaving it rarely works: the body just switches to mouth breathing, and pulling harder through a narrow valve sucks the side walls further in (Bloching 2008). Three quick fixes backfire:

• A decongestant spray every night: used for more than 5 days, it can make the block worse (NHS).
• Menthol rubs: the nose feels clearer (Eccles 2003), but feeling open and being open are separate things (Jones 1989).
• Taping the mouth shut: it forces nose breathing without opening the nose, and is risky when the nose is blocked (Rhee 2025).

What does work falls into three routes.

NHS guidance tries rinses and steroid sprays for at least 6 weeks before referring on (NHS Tayside).

Frido's option sits in route 2. A strip works like a leaf spring: it lifts the side walls outward and holds the valve open on each breath in (Bloching 2008). In one study a strip raised airflow through the valve by 21% and cut resistance by 27% (Dinardi 2014).

Neither strip clears mucus, treats an allergy or straightens a septum.

Can say: holds the front of the nose open while you sleep; drug-free; works alongside rinses and sprays. Can't say: cures a blocked nose, treats sleep apnoea, stops snoring, boosts sports performance (Dinardi 2020) or "clinically proven". We found no study of Frido's own strips.

Best fit: the Pro. A strip only works while it stays on, and the Pro has the stronger grip Frido designs for overnight wear (Frido). The regular strip suits occasional use, such as a cold or a flight.

Make it work: wash and dry the nose, place the strip across the widest part just above the nostril flare, and wet it before peeling it off (Frido). Suggest it when the cheek-pull test helps: that is the patient whose side walls are part of the problem.

In the Frido Care app, add a strip to the plan only when your findings call for one; you accept, edit or drop every suggestion. Frido ships it to the patient directly.

Assess: history, NOSE score, the side walls on a quiet breath in, the cheek-pull test and, if available, peak nasal inspiratory flow with and without a strip (Bloching 2008; Ottaviano 2019).

Explain it in plain words

"Just inside your nostrils is a small doorway, the nasal valve. When the lining swells or the soft sides get sucked in, it closes, and you breathe through your mouth, which brings the snoring and the tired mornings. Once we know what's closing it, there's a fix for each cause."

Their nightly routine

Rinse if stuffy, use the steroid spray if prescribed, put on a strip if pulling the cheek outward helps, and sleep with the head raised (Calvo-Henríquez 2021). No mouth taping (Rhee 2025), and no decongestant for more than 5 days (NHS). Re-score after two weeks.

In a 3-month trial, tongue and throat exercises roughly halved measured snoring (Ieto 2015); a Cochrane review found smaller gains (Cochrane 2020).
