Ayurvedicaly speaking, the common cold results largely from an imbalance of the Kapha (water and earth) and Vata (air and space) elements in the mind-ody. Vata imbalances lower immunity and lead to a build up of the Kapha dosha elements to help ‘ground’ the system. However, Kapha mechanisms typically overcompensate to make up for the ‘dryness’ associated with imbalanced Vata and lowered immunity. The result is excessive ‘coldness’ that creates mucus. This in turn reduces your gastric fire often cuasing you to experience the ‘chills.’
