When the cool winds of autumn begin blowing it is the season of vata, according to the traditional Indian natural health system of ayurveda. Ayurveda recognises that each individual’s constitution is a unique combination of three principles called doshas – vata, pitta and kapha – with one dosha usually more dominant. As vata predominates in autumn, vata imbalance is common to all doshas, with symptoms including anxiety, stress, restlessness, exhaustion and underweight. But there are plenty of tips and techniques you can use to rug up against vata imbalance.
