Common Scents: The Whiff of Loneliness

A dog’s nose is an estimated 100 times more sensitive than human noses. Humans have five million sensory receptors in our brain, dogs have 300 million receptors and compared to them, our own olfactory receptors are puny.

Human scent is something we all have. The way we smell to ourselves and to others--including dogs and people, can reveal a lot. It can tell us about the kind of food we’re eating, or should be eating, the environment we’re in, whether we slept well last night or if we’re sleepy right now. Our scent can tell us if we’re feeling anxious or uncertain, powerful and confident.

 

Our smell can even tell us if we’re lonely.
