Yes, it's true. Bikram Yoga is one of the most therapeutic forms of hatha yoga available today. It's also a very vigorous style of yoga, and that means you need to give your body time to heal internally if you've had major surgery. Please do not rush back into the room! Use common sense along with your doctor's guidance. And make sure your doctor understands just how vigorous Bikram Yoga is before talking him or her into giving you a release....
I know you're anxious to get started again, but be mindful; and be kind to your body. A good rule of thumb regarding surgery is to give yourself at least 8 weeks to heal before taking class. If you've had something like a hip replacement done, give yourself 6 months. And straight from Bikram's mouth, "take it easy, honey" when you come back. Do not push yourself! Remember there are five aspects of mind that Bikram Yoga bestows, not four: They are, "Faith, Self-control, Determination, Concentration, and PATIENCE!" For goodness sake.... Please, practice patience.

Doing yoga every other day has helped a lot more than the physical therapy that I was prescribed, and it doesn't hurt as much. Getting mobility back can take a long time, but I am being patient!
Some procedures ar so minor, no interruption in the "rotuine" is required. Also, most doctors are clueless as to what a Bikram class involves! If you say, "Doc when can I do yoga again?" to most doctors, the response is likely, "Well, that's not too vigorous, so maybe a couple of weeks, maybe four depending on how you feel." It is important to be specific: "Can I do extreme forward bends, back bends, spinal twisting, and balancing on one leg in a 90+ F degree room for 90 minutes?" This would not only stop most docs in their tracks, it would give them pause as to their "routine" post-operative recommendations.
and have your dentist's okay before taking class again.
