[OFF THE POST] Vienna-based voice coach Ingrid Amon is offering cheering lessons to Austrian fans ahead of the European Championship, because she warns that improper screaming can cause voice loss - and even permanent vocal chord damage. She says fans should avoid alcohol and caffeine, and, apparently unaware that Austrian fans rarely have something to cheer about, says they should take "quiet breaks" during the game. She also recommends body movement while screaming: "Shaking your popsch [booty] helps the most."

The European Championship, co-hosted by Austria and Switzerland takes place June 7-29.

"Don't scream continuously," advises Amon. "Take breaks and vary your pitch."

She says fans can prepare by using their voices daily in the weeks before the tournament by singing in the shower or to tunes on the radio while driving.

She recommends water and tea instead of beer and energy drinks.
