Studies indicate that certain aromas may promote sounder sleep, enhance dreaming, and improve awareness and receptivity the following day. EEG (electroencelphalogram) tests at the Smell & Taste Treatment and Research Center in Chicago indicate that lavender increases alpha wave activity in the posterior portion of the brain and helps induce sleep. “Alpha wave activity increases when you are relaxed,” says Alana Hirsch, M.D., medical director at the Center. “Put a few drops of lavender pure essential oils on your pillowcase before going to bed,” Hirsch recommends. Studies also show that vanilla helps people fall asleep quicker and promotes faster movement into the REM or dream state, he adds. In addition, research at the Society of Psychophysiological Research found that sleepers in jasmine-scented rooms enjoyed better quality sleep and morning-after alertness than those that slept in a non-scented room. To start sleeping sounder, purchase organic vanilla essential oil at your local natural food store or online.
