Aromatherapy candles, sprays, and oils advertise the promise of sleep-inducing calm, and one study has shown that lavender scents, specifically, may help some people sleep better. But scent is deeply personal; different blends will have different effects on your mood and energy levels. And for people with allergies, any foreign scents (especially those from chemical-filled products) could be irritating instead of relaxing.
Some of the sleep products on drugstore shelves don't contain any medication at all; instead they include a blend of herbs and nondrug ingredientsmainly valerian, melatonin, lemon balm, hops, coenzyme Q10, and chamomile. They're available as pills, tablets, liquid formulas, and even incorporated into mainstream tea products.
For patients who don't want to devote the time or the financial cost to sessions with a cognitive-behavioral therapist, there are countless books and audio recordings that teach techniques for relaxation, meditation, hypnosis, and stress relief.
