Thanks for responding Shawn. I am more concerned with my face and hands getting cold then my lower back, tummy and feet. Am I to understand you are also referring to during the practice as well as after?

I have another question in regards to the best times to practice. I understand that noon and midnight are considered the best. I am trying to arrange my life so that I do the active excercise between eleven and twelve then I do one meditation between twelve and twelve thirty. I then wait half an hour before eating my lunch. Am I getting a lot more benifit working this way or just a little. I ask only because here in Canada the days are short in the winter and I have less daylight to work outside in. I work on a farm so I work a lot outside.

Thanks for your advice.
