Your sense of smell is primal and the smell center of the brain is located close to brain centers that regulate emotion (ever notice how some smells can make you feel nostalgic or happy or sad?) Aromatherapy is a great way to lift your spirits. In general, citrus scents elevate mood. Wear a lemony cologne. Get a diffuser and give your home or office the smell of oranges. Some essential oil companies sell oils for to elevate mood (try “Elevate” oil by DoTerra Essential Oils). Dab a drop or two on your neck (or on the soles of your feet if you don’t like smelling like citrus).
