if you are working in these incredibly warm conditions be sure to drink plenty of fluid.
Take at least a litre of fluid onto the diamond each game and sip after each inning to stay hydrated.
If you are very active and exercise, sweating a lot in the heat, you may need a sodium replacement. Start by drinking water and eating a small, salty snack, or replace electrolytes with a sports drink.
