In Ayurveda, Insomnia is known as Anidra. According to the Ayurvedic perspective, the doshas (Ayurvedic humors) responsible for this disease are Tarpak Kapha, Sadhak Pitta or Prana Vata.
Sleep is a natural phenomenon of giving adequate rest to the body and mind. Insomnia is the inability to fall asleep at night for many hours or inability to have a sound sleep, which deprives one of natural rest and interferes with activities during the day.
An improper diet and lifestyle causes aggravation of Vata (Ayurvedic humor representing Air) that travels through the channels of the head causing sleeplessness. Vata is aggravated by increased intake of tea and coffee, especially, before going to bed; long gaps between meals; and intake of cold and dry food, cabbage, lettuce, beans, cauliflower, broccoli, peas, rice, and smoked foods. Suppressed emotions, disturbed sleeping patterns, worries, anger, overwork, overexcitement, and ill health may be other responsible factors.
Waking up during the night, waking up too early, day time irritability, day time fatigue and sleepiness and difficulty falling asleep at night are some of the symptoms related to insomnia.
