They are not for sound, charging, or air from a device. They let the vapor come through when the person breathes in.
People often use these when they have a cold, allergies, sinus stuffiness, or just want that strong menthol scent to help them feel like they can breathe easier. Some people keep one in a backpack, purse, bedside drawer, car, or jacket pocket because it is small and easy to carry.
It is also very common in many households, especially during cold and allergy season.
The funny part is that if you have never seen one outside its packaging, it really can look suspicious. Without the label, it looks like some tiny mystery object from a teenager’s room.
But it is actually a very ordinary thing.
To use it, most people remove the cap, hold it near one nostril or gently place it at the opening of the nostril, close the other nostril, and breathe in. Then they repeat on the other side. The exact directions can depend on the brand and country, so the label matters.
It is usually not meant to be shared with other people, because anything used around the nose can spread germs. That is one important thing to remember, especially in a family.
It should also be kept closed when not being used, because the vapors can fade if the cap is left off.
For a 16-year-old, this kind of item is not automatically alarming. Many versions are made for adults and older children, and some are labeled for ages 12 and up. Still, it is always smart to check the packaging if available, because some nasal inhalers are non-medicated scented sticks, while others are actual decongestant products with more specific usage limits.
