Worker recommendations for hydrating during work in the heat are limited and generalized to all workers. Despite individual hydration needs depending on a variety of factors including the work intensity, specific environment conditions, or individual needs, all workers are suggested to drink the same amount in a similar fashion. This study challenged this idea by comparing two drinking strategies for work in the heat.

Variations in water consumption patterns equally hydrated workers in the heat. Worker recommendations protect some, but not all, workers from excessive high core body temperature.
