ICY POLES

Initially trialled in 2003 with athletes1 and studied prior to the 2008 Beijing Olympics, the ingestion of ice was shown to be a superior method of lowering core body temperature than fluids served at 4ºC.

In addition to the cooling benefits, crushed ice ingestion also improved endurance performance in the heat.

The cooling benefits observed for elite athletes have been replicated in occupational settings. Firefighters wearing protective clothing while working in an extremely hot fire cell were able to lower their core body temperature more effectively when they consumed crushed ice during a rest break than the standard practice of resting in the shade with a cold drink.
