Which of the following is a protective health behaviour?

• A. Smoking.
• B. Regular physical activity.
• C. Excessive alcohol consumption.
• D. Poor diet.

Answer: (B)

Protective health behaviours are actions that reduce health risks and promote wellbeing. Regular physical activity fits this because it lowers the risk of heart disease, stroke, type 2 diabetes, and some cancers, helps with weight management, and improves mental health, sleep, and overall energy. Even moderate, regular activity adds up to meaningful benefits and aligns with public guidelines that encourage most days of activity plus strength work. By contrast, smoking, high alcohol use, and a poor diet increase health risks, so they are not protective behaviours.
