Hoping to provide a solution for insomniacs is Sprayable Sleep, a skin spray that claims to send users into a slumber within an hour. The product only has 3 ingredients — water, tyrosine (a natural amino acid), and melatonin. According to the company, melatonin pills can deliver an instant hit of the sleep-inducing chemical to the body, with the sometimes unwanted side effect of essentially being knocked out for several hours. Sprayable Sleep differs in its delivery method — by rubbing the spray into the skin, the body absorbs the chemical more slowly, mimicking the body’s naturally gradual release. Because of this, users need to spray about an hour before they intend to sleep.
