ELI5: Why do treadmills and elliptical machines have that 5 minute cool down time after a programmed workout. Is it necessary?

Short answer - intense exercise causes changes to your circulatory system, especially in your legs. A rapid and sudden STOP in intense exercise can cause a sudden problem with things like dizziness or loss of consciousness. Since treadmills are typically in places where a person who drops unconscious might get hurt and start a lawsuit. they incorporate a cooldown to help prevent this, and they can always blame you for misusing the machine if you ignore it.
