The new chill in the air means lots of things. The winter coat is coming out of the wardrobe.  Soup is back is on the menu.  And our summer of lovely breezes through the open door and windows of the yoga room are going to turn into a slightly more cosy affair.  Luckily yoga has all manner of ways of keeping us toasty. There's no better time for a sun salutation than when it starts to become more of a precious commodity!
