YOU MAY HAVE heard the insult “mouth-breather” in recent years thanks to the popularity of the show Stranger Things. There are actually many good health reasons to avoid breathing through your mouth if nose breathing is possible. We should consider mouth breathing an emergency backup, not our main way to breathe. In both the short term and the long term, mouth breathing has negative health effects.
There are several negative effects of mouth breathing that kick in either immediately or very quickly. A major one is lower oxygen levels. When we breathe through our noses, we trigger nitric oxygen production, which helps our lungs absorb oxygen. Mouth breathing skips this process, making it harder to get the most out of each breath, resulting in less oxygen absorbed and less energy for mental and physical tasks. Other short-term effects include:
The short-term effects are already unpleasant, but a mouth-breathing habit can lead to worse issues if it continues, including serious developmental effects for kids who grow up with this habit.
Some people breathe through their mouths because of a problem with regular nose-breathing, like a deviated septum or a sinus infection, but anyone who can comfortably breathe through their nose should try to do that as their default option. We’re happy to answer any questions you may have about mouth breathing and its impacts on oral health.
