Vous avez remarqué qu’une de vos narines respire souvent mieux que l’autre ? C’est tout à …more

what it claims

The alternation of one nostril being clearer than the other throughout the day is a normal, natural phenomenon (the nasal cycle) and does not mean your nose is congested; however, constant obstruction or frequent mouth breathing requires a consultation.

This alternating phenomenon is entirely real and scientifically validated as the nasal cycle.

This alternating phenomenon is entirely real and scientifically validated as the nasal cycle. Physiological observational studies, notably synthesized in scientific literature reviews (such as that by Kahana-Zwerdling), confirm that this cycle of alternating swelling affects the majority of adults. It is a natural mechanism driven by our internal regulatory system to humidify the air and alternately rest each side of the nose. The creator is quite right to reassure: experiencing this temporary asymmetry is a sign of normal functioning, not a congested nose. Finally, their suggestion to consult a professional in cases of continuous obstruction is very sound for overall health. Indeed, long-term mouth breathing can impair recovery quality and daily energy.

Floss before brushing to clear plaque and debris from interdental spaces, allowing the fluoride in your toothpaste to better penetrate these areas and protect the teeth.

Flossing before brushing helps remove plaque and debris, thereby facilitating access and the protective action of the fluoride in toothpaste within the interdental spaces.

Others on this

It's not just "anxiety" but a nervous system stuck on alert — cortisol supposedly tightens the chest and shortens the breath; regulating the nervous system (not just "calming down") would quickly undo that.

The 4-4-4-4 pattern (inhale 4, hold 4, exhale 4, hold 4) is slow box breathing that can genuinely calm you down within a few cycles — but the 4-second holds don't add anything proven over plain slow breathing.

mixedMindset Therapy

4-2-6 breathing (inhale 4, hold 2, exhale 6, hold) leans on making the exhale longer than the inhale — the idea has real scientific backing, but the literature is more divided than advertised on this exact recipe.

Noli has read similar claims

Other advice in the Register that leans on the same research.

Mouth tape (taping your mouth shut to force nasal breathing during sleep) hasn't been shown to stop you 'breathing in nasty stuff' while you sleep — and it carries a real risk if your nose is blocked or if you have undiagnosed sleep apnea.

not provennathan

Breathing through the nose rather than the mouth filters, warms, and humidifies air, and a nose that's chronically blocked in favor of mouth breathing is worth flagging to a professional — especially alongside snoring, unrefreshing sleep, or neck tension.

Drooling on your pillow, waking up tired, frequent snoring, and nighttime thirst are all indicators of mouth breathing during sleep.
