===Weakness of indriya (indriya daurbalya) ===
===Weakness of indriya (indriya daurbalya) ===
The indriya become weak and less efficient due to abnormal increase of [[pitta]] [[dosha]] and decrease of [[vata]] and [[kapha]] dosha. [Cha. Sa. Sutra Sthana 17/60], [Su. Sa. Sutra Sthana 15 /13]. The weakness may be either due to anatomical abnormality of the structural abode of these faculties or the functional abnormality in their controlling system. [Dalhana, Su. Sa. Sutra Sthana 15 /13].

The important cause of this condition is consumption of incompatible foods (viruddha ahara). [Su. Sa. Sutra Sthana 20/19]. Studies have shown that dietary intake of green leafy vegetables, glycaemic index, and omega-3 fatty acid, as well as overall dietary pattern can influence the risk factors of visual impairment. Low intakes of fat and protein have been associated with hearing discomfort.

===Complete functional loss of indriya ===
===Complete functional loss of indriya ===
When abnormally increased [[vata]] [[dosha]] affects the sensory faculties, they have a total loss of function (indriya vadha). [Cha.Sa.[[Chikitsa Sthana]] 28/29], [Su. Sa. Nidana Sthana 1/24]
When abnormally increased [[vata]] [[dosha]] affects the sensory faculties, they have a total loss of function (indriya vadha).[Cha.Sa.[[Chikitsa Sthana]] 28/29], [Su. Sa. Nidana Sthana 1/24]
When the total loss of senses (indriya nasha) is associated with any disease condition, it indicates the bad prognosis of the disease. [Cha.Sa.[[Sutra Sthana]] 10/20]
*Loss of function of sensory faculties (indriya nasha) is mentioned as a diagnostic feature in severe jwara.[Cha.Sa.[[Chikitsa Sthana]] 3/51]
*When the poison (visha) gets accumulated in the large intestine (pakwashaya), it produces disorders in the functioning of sensory faculties. [Su. Sa. Kalpa Sthana 1/42]
Improper indulgence in sensory and motor activities (asatmya indriyartha samyoga) :
*Excessive administration of nasal errhines (nasya) results in dysfunction of sensory faculties. [Su. Sa. Chikitsa Sthana 40/ 40]
Improper, less or excess indulgence in sensory and motor activities is an important fundamental cause of any disease. [Cha. Sa. [[Sutra Sthana]] 8/15] The diseases related to indriya (aindriyaka vyadhi) are caused by non – utilization (ayoga), excessive utilization (atiyoga) and malpractice (mithya yoga) of sense or motor faculties. [ Cha. Sa. [[Sharira Sthana]] 1/128]
*In diseases due to excessive nourishment (santarpanottha vyadhi), due to aggravation of [[kapha]] [[dosha]], diminished functioning of sensory faculties is seen. [Cha. Sa. [[Sutra Sthana]] 23/17]It is advised to perform therapeutic emesis (vamana) in case of [[kapha]] predominant fever (jwara) for correcting the functions of sensory faculties. [ Su. Sa. Uttara Tantra 39/129]

== Effect of ageing on indriya ==
== Effect of ageing on indriya ==
The power of sensory and motor faculties decreases with age. It is evident that after the age of forty years, the power starts decreasing gradually and it becomes more evident after age of seventy years. [Su. Sa. Sutra Sthana 35/29] Rasayana (rejuvenation) therapies shall be started well in advance at younger age to prevent this loss due to ageing.
