Please bear in mind that I have no medical degree and am not a medical professional. The advice given is that of a Yoga Teacher. Always consult with your physician for a professional opinion.
Generally speaking this does apply to untreated Yoga students with high blood pressure.
However, when you have a new student with high blood pressure or any other ailment, you should always have them clear it with their physician, by getting formal permission to take classes. Even if your student is taking proper medication and the blood pressure readings are normal.
The doctor’s answer for students who are on prescriptions and middle-aged or younger is usually the same. The student is fine, and can take classes, if they stay on their prescription. However, the student should still get his or her doctor’s approval before participating in Yoga training sessions.
Why should you concern yourself with this? For the safety of each student, your peace of mind, to stay in touch with the medical community, and to avoid potential liability suits.
Staying in touch, by opening lines of communication, with the medical community will also bring you referrals and many more students.
The liability factor can be financially devastating, so never take anything for granted and as a Yoga teacher – never “play doctor.”
