Hello Renie,
Wow another bout after that episode in April?
I have a few things to share with you.
First I’d like to clarify the question and shift it from “can I do yoga?” because I believe you are actually asking about asana. Yoga is something lived. Asana is something formed with the body. Please continue to do the first but refrain from the second until your body is ready to mobilize.
Obviously, anyone can get sick, ill, catch a cold or get the flu. And while I’ve read some things indicating the most recent version of flu hits young people with strong immune systems the worst, I cannot verify such a thing.
What we learn (hopefully) is that disease is a form of communication from body to mind. Thing of it as a 911 call of one degree or another. The question is what is the message and how best do we heed it.
When we fail to listen to that call AND continue to place great physical demand on our body it can weaken the immune system (activity burn out). In that scenario the body will continue to send messages, escalating them from whisper to shout. If none are heeded then you’ll get knocked on your butt.
There are ways to support and bolster the immune system and while activity and movement are critical for human well being it is not the most direct method for that immune system support. The immune system functions best when the nervous system is parasympathetic and that equals “at rest”.
So in the case you’ve broached I would ask the student to rest, meditate, and do specific things relative to nutrition and lifestyle. But I would not ask them to do asana.
