Most people worry about bad breath at some point — before a meeting, a date, or even just chatting with friends. The funny thing is… we’re usually the last ones to notice our own breath. Our noses get used to our natural smell, so we can’t always tell when something’s off.
But don’t worry. There are simple, science-backed ways to check your breath quickly and privately. Here’s the SmellWhisper way to do it.
👃 Why It’s Hard to Smell Your Own Breath
Your brain is smart — sometimes too smart. It filters out familiar smells so you’re not constantly distracted by your own scent. This is called sensory adaptation, and it’s the reason you can’t smell your own perfume after a few minutes.
Great for survival.
Not great for knowing if your breath is fresh.
