In terms of the ayurvedic doshas, nasya is recommended as a practice for balancing all the doshas, but particularly the vata dosha. This is because it is considered beneficial on a physical level to:
- Alleviate dry nasal passageways
- Ease sore throats
- Improve a hoarse voice
- Release stiffness in the head, neck and jaw
- Relieve headaches
- Improve eye problems
On a mental level, nasya is also said to relieve stress, anxiety and fear. Some claim that it can reduce chronic sinusitis, myopia and cervical spondylosis.
Yogis believe the nose is a direct route to the brain and the entrance for the breath, or prana. Having healthy breathing passageways is considered essential for the efficient passage of prana into the body.
