Re:Yoga Teaching Fatigue

Hello Ayehasherayeh - I have been teaching hatha for several years in the uk - last year I was offered work at a local gym teaching 3 classes on one day - with my own studio class it meant 4 classes on that day (total of 4 and half hours) - things were ok at first, I was just a little tired on the following day and that fortunately is the one day I do not teach - but in the last few months I have been experiencing heavy fatige and a feeling of high stress on the days following these classes, even headaches - it is now taking me two days to recover from this heavy teaching day - I have tried to cut down on my input (posture demonstrating)and have a very healthy Diet but this doesn't seem to help - is there anything I can do with my yoga to counter these effects?
Best Wishes
