One of the major factors contributing to growth of the sleeping aids market is the rising number of insomnia cases. According to the Centers for Disease Control and Prevention (CDC), in 2016, around 70 million adults suffered from insomnia in the U.S., with men reporting a higher rate of insomnia cases. Moreover, increasing geriatric population, changing life style with increase in consumption of alcohol, caffeine, and smoking, are some other factors leading to sleeping disorders. For instance, caffeine blocks the effectiveness of adenosine, a chemical that helps to bring on drowsiness and to regulate the sleep wake cycles. Furthermore, Side effects associated with sleeping aids medication include dizziness, dry mouth, headache, stomach ache, and constipation, which hinders growth of the market.
