If you are paying attention to eating seasonally you will notice more earthy root vegetables, pumpkin, very dark leafy greens, and heavier fruits begin to be in season. These are precisely the foods that ground you, warm you, create a bit of moisture in your body, exactly what is needed to keep Vata in check. Vata, when left unchecked, is the source of those nasty coughs and colds that develop around this time of year.
Bear in mind if you are overweight you will still want to follow a partly Kapha diet but add warming Vata foods to the mix. You will also want to stay more active in keeping with a Kapha lifestyle. If you have a Pitta imbalance or live in an environment where it is still very hot you will still want to maintain a slightly Pitta diet until Vata type foods become available seasonally in your area.
A wonderful reader of mine turned me onto a man named Yogi Cameron, a model turned Ayurvedic lifestyle expert. (And a really nice bit of eye candy too!) I resonate to a lot of what he says and it lines up perfectly with my own training. Because yoga is so much a part of the Ayurvedic lifestyle, indeed it should be an integral part of any healthy lifestyle, when I found this video with Yogi Cameron doing vata balancing postures I had to post them.
I myself, being a Vata, and now pregnant (a huge time for Vata), do these postures to keep myself balanced. Abhyanga (with sesame or almond oil) and Pranayama are also practices to integrate during this Vata time.
Wishing you peace and balance. Namaste!
