Which practice should be avoided during pulmonary hypertension exercise?

• A. Very low-intensity aerobic exercise.
• B. Breath-holding.
• C. Light stretching.
• D. Short breaks as needed.

Answer: (B)

Breath-holding during exertion is risky for someone with pulmonary hypertension. When you hold your breath, you can trigger a Valsalva-like response: intrathoracic pressure rises, venous return to the heart drops, and pulmonary artery pressures can spike. In pulmonary hypertension, the vessels are already stressed, so these sudden pressure changes can worsen shortness of breath, decrease blood flow to the brain and muscles, and increase the risk of dizziness or fainting. Keeping breathing steady and avoiding holding the breath helps maintain stable circulation and oxygen delivery during exercise. By contrast, very low-intensity aerobic work is generally safe and beneficial for conditioning, light stretching aids flexibility, and taking short breaks as needed helps manage symptoms and pacing during a session.
