Honey is another old time, long-trusted sleep remedy. We now know this is because, like milk, it helps the brain produce a calming, relaxing chemical called serotonin. Serotonin is a neurotransmitter, a chemical which governs brain activity. The body makes serotonin from the protein, tryptophan. It is found in foods such as milk and honey.
Sleep is a great healer.
A good night's sleep is necessary for the brain to process all things it learns during the day. Sleep inducing drugs interfere with natural patterns of brain activity during sleep. Better health may be as simple as getting enough sleep. Those who habitually get too little sleep can suffer loss of initiative and energy, and be more prone to attention lapses. Research from Cornell University reinforces this.
