Undergraduates at a West Virginia university have found that smelling peppermint and cinnamon helps drivers stay alert and calm.

The students found that peppermint on its own reduced anxiety and fatigue, while peppermint and cinnamon in combination reduced frustration and temporal demand and increased alertness.

'Periodic administration of these odors over long-term driving may prove beneficial in maintaining alertness and decreasing highway accidents and fatalities,' Raudenbush said."
