Will doterra wild orange essential oil sprinkled all over my bed sheets cause me to have insomnia?

Unlikely but...: Orange essential oil has many proven health benefits. Sprinkled on sheets it will act as aromatherapy. In this form it's been shown to be a natural tranquilizer, inducing physiological and psychological relaxation. Thus, it's more likely to help you sleep than cause insomnia.But just as some people may be stimulated by sedative drugs,it might rarely cause insomnia.See https://draxe.com/orange-oil/

NO: No harm. No benefit. "Aroma therapy" is junk science sold to suckers. Continue behavior therapy. It is the best long-term approach to insomnia. [Cognitive behavior therapy}
