First of all, tell us about the pranayams you are doing. Primarily, all pranayams, in one way or another, burn toxins in your body. you will feel rejuvenated with just few sessions. Next, yes, pranayams do increase your body vibrations. Your body is always vibrating but most of the time we are not consciously aware of it. Suddenly, you are aware and that’s a good thing.
If you don’t control the vibrations, reduce the pranayams. If you are enjoying it and feeling better keep doing them. Also, don’t force yourself into anything. Here’s the tricky part. Listen to your body. Don’t listen to your mind. Your body will give you answers.
