Diffused oils alter the structure of molecules that create odors, rather than masking them. They also increase oxygen availability, produce negative ions, and release natural ozone. Many essential oils are extremely effective for eliminating and destroying airborne germs and bacteria.
Aroma lamps and candles can render the oil therapeutically less beneficial and can create toxic compounds. Burned oils may become carcinogenic. Research shows that cold air diffusing certain oils may: reduce bacteria, fungus, mold, and unpleasant odors; relax the body, relieve tension, and clear the mind; help with weight management; improve concentration, alertness, and mental clarity; stimulate neurotransmitters; stimulate secretion of endorphins; stimulate growth hormone production and receptivity; improve the secretion of IgA antibodies that fight candida; improve digestive function; improve hormonal balance; and relieve headaches.
Start by diffusing oils for 15 – 30 minutes a day. As you become accustomed to the oils and recognize their effects, you may increase the diffusing time to 1-2 hours per day.
