Pick a slower song and dance to it--just be sure you are still moving your body, but going from a fast paced rhythm to a slower paced rhythm. If you just stop cold turkey after dancing, you will put your body at risk.
Be sure to take the time to slow down your heartbeat the proper way.
Extend your body in place during yoga movements. The most common yoga movements are the childlike pose and the downward facing dog pose.
Sit on the floor and open your legs to a straddle position. Keep your knees locked straight and lean forward, reaching your arms in front of you. Try to keep your back as straight as you can.
Stay in the same position as the above step, but bend one leg behind you. Stretch forward trying to touch the toe of the extending leg, while keeping your back as straight as you can.
Stand up and keep your shoulders back with your back straight. Place one arm bent on your hip and take the other arm and reach up to the sky, bend at the waist and extend your arm to the opposite side of your body making a "c" shape. Do the same with the other arm.
Step one leg in front of the other in a lunge position. Slowly lower the back leg and bend the knee as you lunge forward. Do the same lunge stretch for the other leg.
