Modifying Pranayama for a Hypertensive Trainee Who Became Dizzy
A 56-year-old bank clerk joins a 60-minute evening yoga class; this is his third session. He has stage 1 hypertension (148/94 mmHg, on amlodipine 5 mg), mild well-controlled asthma (FEV1 78 per cent predicted, reliever inhaler used about twice a week), resting heart rate 84 bpm, respiratory rate 20, SpO2 96 per cent at rest, and a 20-year sedentary history. He does not smoke. In session two he became dizzy, saw spots and felt chest tightness about two minutes into kapalabhati (three sets of 30 strokes) and had to lie down; he recovered within ten minutes and said he felt "fine afterwards, just embarrassed". The instructor's written plan for session three is kapalabhati 3×30, bhastrika 3×20, anulom-vilom on a 4:16:8 ratio, and jalandhara bandha held with kumbhaka. The studio is on the first floor with no lift and the class has 22 other students.
1. Explain what most likely produced the dizziness and chest tightness, and state which planned practices you would drop or change, with reasons.

Mechanism. Kapalabhati is forceful active expiration with passive recoil; it is a hyperventilation practice. Two things follow. First, blowing off CO2 lowers PaCO2, which constricts cerebral vessels and produces exactly the reported cluster - dizziness, spots before the eyes, tingling. Second, each forceful stroke raises intra-abdominal and intrathoracic pressure, so blood pressure swings upward and venous return changes; in a hypertensive, sedentary 56-year-old that is an avoidable load. Chest tightness is not part of the expected response - in an asthmatic practising rapid, dry, high-minute-ventilation breathing it may be bronchoconstriction, or it may be cardiac. Either way it is a stop-and-refer sign, not a coaching problem.
Drop or change:
- Kapalabhati - drop for now. It is the practice that produced the event, and it is not suitable for uncontrolled or recently diagnosed hypertension or for someone with exertional chest symptoms.
- Bhastrika - drop. Same hyperventilation mechanism, larger tidal volumes, more pressure swings.
- 4:16:8 ratio - drop the 16-count hold. Kumbhaka raises intrathoracic pressure and BP; a long retention in a hypertensive trainee is contraindicated until BP is controlled and cleared.
- Jalandhara bandha with kumbhaka - drop. Jalandhara is taught on a hold; without retention there is nothing to bind.
- Keep: settling, breath awareness, abdominal breathing, anulom-vilom without retention, bhramari, savasana. These give the class the same parasympathetic emphasis without the pressure load.
2. Write the replacement 12–15 minute pranayama segment for session three, giving timings, ratios and the cues you would use, and justify each choice.

Plan (14 minutes, seated on a chair or cushion, spine easy, near the door):
- 2 min - settle and observe. Natural breath, no change. Cue: "notice the breath without fixing it; let the abdomen move." Purpose: baseline, and it lets the instructor see whether he is breathless at rest.
- 4 min - abdominal/diaphragmatic breathing, 4 in : 6 out, about 10 rounds, then natural. Cue: "in through the nose, low into the abdomen; out slower than in, no pause at the end." Justification: a longer exhale than inhale increases parasympathetic tone and produces a modest fall in heart rate and blood pressure; the absence of a pause avoids Valsalva.
- 5 min - anulom-vilom without retention, 4 in : 6 out, alternating nostrils, no hold. Cue: "if the breath snatches, shorten the count; never force the count." Justification: keeps the calming effect, removes the 16-count retention that raises intrathoracic pressure.
- 2 min - bhramari, 5 rounds, low hum, long exhale. Justification: prolonged exhalation, low effort, and it is easy to self-monitor.
- 1 min - quiet sitting, normal breath.
Say explicitly to him: stop if there is dizziness, chest tightness, or the breath cannot be made smooth; return to normal breathing; tell the instructor. Do not use breath holds, rapid breathing, or forceful exhalation in this class until his physician has reviewed the chest tightness and his BP is controlled. Give him the same sequence as a 5-minute home practice, twice daily, without retention.
3. What documentation, referral and progression would you put in place before he returns to a fuller practice?

Referral first. Chest tightness in a 56-year-old hypertensive with a 20-year sedentary history needs medical assessment, not a yoga adjustment. Advise him to see his physician, describe the episode (when it happened, what he was doing, how long it lasted), and ask specifically about exertional symptoms and whether his amlodipine dose and BP control are adequate. Ask for written clearance before any vigorous pranayama, inversion or breath retention.
Documentation. Record in the class register: date, session number, the practice and dose (kapalabhati 3×30), time to onset (about 2 minutes), symptoms (dizziness, spots, chest tightness), vital signs if taken, action taken (stopped, lying down, recovery in 10 minutes), whether he was advised to seek medical review, and who was informed. Note that he takes amlodipine and carries a reliever inhaler; confirm he had the inhaler in the room. An incident note protects the student and the instructor.
Progression, once cleared and BP controlled (for example below 130/80 and no symptoms): weeks 1–4, only the 14-minute segment above, twice weekly, no retention. Weeks 5–8, extend anulom-vilom to a 4:6:8 ratio (short, comfortable hold) only if he remains symptom-free and the physician agrees. Weeks 9–12, introduce a gentle, low-rate kapalabhati (for example 20 strokes × 2, slow) with the option to stop, never in the same session as a long hold. Keep bhastrika and prolonged kumbhaka out of his programme. Re-check BP at the start of each month and log it.
