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.
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.
Tarpak Kapha is a sub-dosha of Kapha (Water). It nourishes the brain cells and facilitates a good night’s sleep. Imbalance of this dosha causes poor nourishment of brain cells, leading to Insomnia. Sadhak Pitta is a sub-dosha of Pitta (Fire) and is located in the heart. It controls emotions, desires, decisiveness, and spirituality. Its imbalance makes a person demanding and workaholic, thereby leading to situations that may cause lack of sleep. Prana Vata is a sub-dosha of Vata (Air). It is linked to insomnia, worry, anxiety, and problems like depression. Prana Vata makes the nervous system sensitive; this sensitive nervous system coupled with an aggravated Prana Vata lead to insomnia.
In each patient, different combinations of doshas can lead to the disease. The Ayurvedic treatment of Insomnia focuses on balancing the aggravated body energies through herbal medicines as well as customized diet and lifestyle plans. Besides that, relaxation of mind is also important part of the treatment.
