How many minutes should a heart cool-down last?

• A. 0-5 Minutes
• B. 5-10 Minutes
• C. 10-15 Minutes
• D. 1-3 Minutes

Answer: (D)

After exercising, a brief cool-down helps the body transition gradually from activity to rest, letting the heart rate and blood vessels return toward resting levels and reducing the risk of dizziness or faintness from abrupt stopping. The best option here is a short cool-down of 1-3 minutes because it provides enough light activity to keep blood moving and venous return steady without extending the workout too long. A quick walk or very easy cycling for a few minutes is enough to stabilize heart rate and breathing, and you can then move into gentle stretches. In more intense or longer sessions, a longer cooldown (like 5-10 minutes) might be used, but for the context of this item, 1-3 minutes is the expected duration.
