Can peppermint scent help you feel more alert? What studies actually show
One study found benefits. Others didn’t. A closer look at the mixed results.
In this article
Peppermint and alertness is an interesting research topic, but the findings are mixed. These studies do not establish that a viff inhaler improves focus or memory.
A study that found differences
Moss and colleagues randomly assigned 144 volunteers to peppermint aroma, ylang-ylang aroma or no-aroma conditions. They reported differences favouring peppermint on memory measures and self-rated alertness. [1]
That is worth knowing. It is also one experiment, with particular exposure conditions and tests. Feeling alert and performing better on every attention task are not interchangeable outcomes.
Other experiments tell a less simple story
A 2010 study examined several odorants, including peppermint oil, during a visual vigilance task. Comparisons with a control group did not show the expected performance effects. [2]
A later paper, published online in December 2024 and in a 2025 journal issue, tested a specific claim about peppermint, lavender and the “attentional blink”: difficulty spotting a second target soon after a first. Across three experiments, the researchers found no evidence that the scents changed that effect. [3]
What can we fairly say?
The experiments used different tasks and exposures, so they are not identical tests of one promise. A null result on one task does not erase every other finding; a positive result on another does not establish a general focus benefit.
None of these studies tested a viff inhaler. We describe ours as a pocket-sized scent refresh, without promising improved concentration, memory or productivity.
