A sleep disorder in which you have trouble falling and staying asleep is called insomnia. The causes of this condition include poor sleeping habits, depression, anxiety, lack of exercise etc. People who have insomnia always feel tired or not well-rested. The Ayurvedic approach to insomnia is to re-establish balance and restore natural sleep-wake cycles. Ayurvedic medicines for insomnia are made using 100% pure herbs, and hence, they don't have any side effects, nor are they habit-forming..
