Aromas can affect body chemistry
(HealthDayNews) -- Smells can be pleasant or unpleasant -- sweet or sour -- but do they have any direct effect on your mind?
Yes, according to researchers at Cognition and Brain Sciences Research Centre, Middlesex University, London.
The International Journal of Psychophysiology reports that subjects were attached to an electroencephalograph (EEG) and exposed to a series of odors -- chocolate, baked beans and rotten pork.
The scent of chocolate consistently resulted in a reduction of the theta waves on the EEG, which indicates relaxation.
