We can follow Ayurveda for good health and longevity of life. Ayurveda is not only a ‘Sastra’ to cure the diseases, but also helps in one’s physical, mental and spiritual health and well-being.
One of the classifications of diseases according to Ayurveda is ‘Nija’ and ‘Agantuka’.
‘Nija’ is diseases caused due to internal causes/factors.
Diseases caused due to external factors are ‘Agantuka’.
Main reasons for spread of the communicable diseases are lack of cleanliness and immunity. The ways to lead a healthy life is clearly mentioned in the chapter ‘Dinacharya’ from Ashtanga Hrudaya Sutrasthana.
