2. Hold Your Breath
What To Do: Take a deep breath and hold it for as long as you possibly can. It may help to pinch your nose closed to help prevent you from exhaling. This is especially effective for children, who may find it hard to concentrate on not exhaling.
How It Works: Holding your breath forces you to take control of the diaphragm and stops the spasm. In addition, taking a deep breath stretches the diaphragm and may help it to relax.
Other Tips: Try counting to 20 or 30 while holding your breath.
