From Pathfinder Wiki
The cool down phase should last for about five minutes after the aerobic phase. It allows the heart to gradually slow down. If you were jogging, walk around for five minutes. If you were swimming, walk around in the shallow end of the pool. If you were bicycling, get off the bike and walk it around for five minutes. Most heart attacks that happen in conjunction with an exercise program occur after the aerobic phase. Allowing the heart to gradually slow protects it and lessens the chance of an incident.
