Which of the following is a contraindication to exercise for someone with asthma?

• A. Allergies.
• B. Regular medication.
• C. Acute asthma attack or poorly controlled symptoms.
• D. Daily mild exercise.

Answer: (C)

The key idea is that you only exercise when asthma is well controlled. An acute asthma attack or poorly controlled symptoms make exertion unsafe because the airways are inflamed and hyperresponsive. As you work harder, breathing increases and the airways can constrict further, potentially leading to severe shortness of breath, lower oxygen levels, and a worse attack. Treatment and rest are needed until control is regained and lung function improves, after which gradual return to activity can be planned with an action plan and appropriate use of rescue inhalers.

Allergies can be triggers but aren’t a blanket contraindication; with proper management, exercise can still be safe. Regular medication isn’t a barrier to exercise—it's essential for maintaining control. Daily mild exercise, when asthma is controlled, is generally beneficial and encouraged.
