Put on a happy scent
Since the areas of the brain that process olfaction and emotion are linked, smelling a scent that appeals to you improves your mood. To enjoy your favorite fragrance all day, spritz it on your wrists and forearms, says Alan Hirsch, MD, neurological director of the Smell & Taste Treatment and Research Foundation. With every gesture, you'll catch a whiff. Idole d'Armani (above) tops rose and jasmine with crisp notes of orange and pear.
