what it claims

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

The link between these various indicators and nighttime mouth breathing is well-supported by sleep science. According to institutions like the Cleveland Clinic and the Fondation du Souffle (expert opinion), breathing through the mouth bypasses natural nasal humidification, which dries out the throat, causes thirst, and encourages drooling since the jaw remains open. For its part, the Société de Pneumologie de Langue Française (clinical consensus) directly associates this breathing pattern with repeated snoring. As for fatigue, the Sleep Foundation (literature review) explains that air passing through the mouth deprives the body of nitric oxide produced in the nose, a gas that helps optimize oxygenation and promotes deep, restorative sleep. However, it should be noted that drooling or waking up tired can also stem from factors such as poor sleep posture or digestive issues. Nevertheless, exploring one's nocturnal breathing remains an excellent key to maximizing daytime 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

Needlessly delaying bedtime ("bedtime procrastination") is framed here as coming from not having processed the day's emotions — working through them before bed supposedly helps you fall asleep.

Sleep isn't dead time for your muscles — muscle protein synthesis keeps repairing and rebuilding tissue damaged during the day while you're out.

If you run hot at night, cooling the bed down (a fan, a cooling pad, or a cooled mattress) genuinely helps you sleep better.

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.

mixedDavid Abbasi, MD

If you sleep 8 hours a day but remain tired, this may be explained by specific physical factors to explore: sleep apnea, an iron deficiency (particularly in women and vegetarians), a lack of vitamin D (ideally between 30 and 50 ng/mL) or B12, or even hormonal fluctuations.
