Is it true that my right nostril smells things better than my left?

We sometimes hear that we have one nostril that works better than the other in smelling. And when smelling food or wine, some may tilt their heads to facilitate access to one of the two nostrils. But is it really the case that one nostril is stronger than the other?

Let's start by saying that only a small percentage of the air we inhale reaches our olfactory receptors. It is therefore important to have the "passage" unobstructed and indeed "sniff" strongly to increase the amount of air (aromatic molecules) that reaches our olfactory receptors. The existence of a stronger nostril is actually true only if there are individual anatomical causes that make the passage of air difficult from one of the two nostrils, but in most cases this is not the case.

Indeed, the opposite is true. And so you have to smell with both nostrils together. This is also a consequence of our recently discovered "olfactory mechanism" known to few: inside the nose there are tissues that swell and deflate alternately every 2-3 hours, partially opening and closing the passage of air in the two nostrils alternately.

At all times, therefore, it is true that one nostril works better (it is freer than the other) but we cannot know which of the two it is. Always sniffing with the same nostril (the one we consider strongest) causes us to risk actually using the one that is less functional at that moment. So when smelling TasterPlace aromas remember to use both nostrils or to transfer the mini bottle from one nostril to the other in order to ensure you best perceive them!
