Yoga Prescription for a Hypertensive Clerk
A 54-year-old school clerk has a body mass index of 31.4 and blood pressure recorded as 148/94 mmHg on two separate occasions. He takes amlodipine 5 mg daily, has grade 2 osteoarthritis of both knees, sits for most of the day, reports poor sleep and feels constantly rushed. He joins a six-week evening yoga camp organised in the school hall. The instructor's planned routine for the whole group is a fast 12-round surya namaskar, then sirsasana (headstand) and sarvangasana (shoulderstand) held for two minutes each, followed by 100 strokes of kapalbhati with breath retention, and a two-minute shavasana. The clerk is enthusiastic and asks the physical education teacher whether he can stop his tablets once his blood pressure comes down through yoga.
1. Identify which elements of the planned routine are inappropriate for this man and explain the physiological reasoning for each.

Four elements are unsafe. The inversions - sirsasana and sarvangasana, and by extension halasana - raise intracranial and intraocular pressure and produce a marked pressor response; in a man whose pressure is already 148/94, sustained inversion risks a dangerous spike. Breath retention, kumbhaka, raises intrathoracic pressure, reduces venous return and then raises blood pressure and heart rate on release; it is contraindicated in uncontrolled hypertension. Kapalbhati at 100 forceful strokes combines rapid forced expirations with abdominal straining, which can raise blood pressure and cause dizziness, and it is a poor starting point for a sedentary, obese beginner; if used at all, it should begin at 20-30 gentle strokes after weeks of preparation. A fast 12-round surya namaskar is a demanding cardiovascular sequence involving repeated deep knee flexion and plank loading, which is inappropriate for grade 2 knee osteoarthritis and for an untrained man. The two-minute shavasana is far too short to produce relaxation. The general principle is that the routine is designed for healthy young participants and must be individualised.
2. Construct a safe 20-minute session for him, naming specific asanas and pranayamas, with knee precautions and the rationale.

Begin with five minutes of gentle mobilisation - neck rolls, shoulder circles, ankle and wrist rotations, standing hip circles - to warm joints without loading the knees. Then tadasana with attention to posture; vrikshasana standing with a wall or chair for support, twenty seconds each side, which trains balance without knee strain; ardha kati chakrasana, standing side bends, for the trunk; a gentle seated forward bend using a chair or with the knees slightly bent and a folded blanket under the hips, never forcing the hamstrings. Makarasana prone relaxation is safe for both knees and blood pressure. Avoid deep squatting, long-held vajrasana, padmasana and any kneeling posture that compresses the patellofemoral joint; if sitting on the floor is needed, sit on a low stool. For pranayama, use nadi shodhana and bhramari without any retention, breathing smoothly through the nose, for five minutes; both slow the breath and promote parasympathetic tone without pressure spikes. End with shavasana for six to eight minutes with a blanket, since sufficient relaxation time, not the asanas alone, is what lowers arousal.
3. Answer his question about stopping medication and set out how the yoga should be monitored alongside medical care.

He must not stop amlodipine on his own. Hypertension is usually asymptomatic, so feeling well is not evidence that pressure is controlled, and stopping suddenly can produce rebound rises. Yoga, weight reduction, salt restriction and walking are adjuncts that may allow a doctor to reduce the dose later; they do not replace the drug in the short term. Explain the reasoning: a single normal reading at a camp proves nothing, because pressure fluctuates. Practical monitoring: record home blood pressure twice weekly, seated after five minutes of rest, and keep a simple log alongside body weight and sleep hours; bring the log to the doctor at four to six weeks. Target a 5-10 per cent weight reduction, salt below 5 g a day, and 30 minutes of brisk walking on non-yoga days, chosen because walking is knee-friendly if pain allows. Warn him to stop and seek review if he develops chest pain, severe headache, breathlessness or dizziness during practice. The correct framing is that the teacher coaches the lifestyle, the doctor manages the medicine, and neither acts alone.
