After you've been doing vigorous exercise, you should do some cool-down before you stop.

Cool-down exercise are like those warm-up exercise, and the only difference is that one is done before the workload and the other is after.

A proper cool-down will continue to lower the heart rate and will also help to prevent excessive pooling of the blood in the lower extremities, reduce muscle soreness, and promote faster removal of metabolic wastes.

You know you're in good state, if, within five minutes of completing a vigorous
workout, your heart rate falls to or below 100 beats per minute.
