I've asked a similar question in the meditation section, but as it's more specific to Taiji/Qigong, I'm hoping that others may share their views or experience here.

I have been told that it's not a good idea to practice energy circulation, Taiji/Qigong or Yoga when you have a virus or bug, as that can feed it and make it more virulent. Although I have practised these systems for nearly 20 years, I'm still struggling with energy circulation and healing applications. Any thoughts?
