The sensation of one nostril feeling more congested than the other is a natural and normal phenomenon known as the "nasal cycle." However, if this blockage is persistent or leads to breathing primarily through the mouth, it is advisable to consult a specialist.

The "nasal cycle" mentioned by the creator is a respiratory health phenomenon that has been very well documented since its description in 1895 by Richard Kayser. A major literature review (evidence type: scientific synthesis) published by Pendolino et al. in 2018 in the journal Rhinology Online confirms that this natural alternation of airflow affects 70% to 80% of healthy adults. This autonomous mechanism helps regulate humidity and filter the air we inhale, with the switch occurring from one nostril to the other every 30 minutes to 6 hours. It is therefore normal to experience a breathing asymmetry throughout the day without cause for concern. Furthermore, research confirms that constant mouth breathing or continuous blockage impairs sleep quality and air filtration. The suggestion to check in with a professional in the event of constant discomfort is therefore fully validated to maintain daily well-being.
