I have started doing kapaalbhaati and anulom vilom only recently(2 weeks back) and I am facing this problem of breathlessnes. is it ok or do I need to see the doctor, I was also under stress as I was at home doing nothing for the last couple of months

I am not sure if you are doing the Pranayam correctly. How to do these powerful exercises, for how long to do these, when to do and in what sequence to these are some of the other things you have to take into account. Again it needs to be clarified if you are breathless all the time or just while doing the Pranayama. If you are breathless all the time ,you should see a Dr. and if its only when you are doing the pranayama then you need to see a Pranayama teacher.
