Effects of Oral Rehydration Solution on Fluid and Electrolyte Replacement and Maintenance in a Heatstroke Dehydration Model—A randomized, Single-blind, Placebo-controlled, Crossover Study—

Key Points

• Evaluate the impact of oral rehydration solution on fluid and electrolyte replenishment during dehydration following sauna exposure.
• Randomized, single-blind, placebo-controlled, crossover study design.
• Participants underwent dehydration treatment after sauna exposure.
• Comparison of effects of oral rehydration solutions versus placebo.
• Oral rehydration solution significantly improved fluid replenishment compared to placebo.
• Electrolyte balance was better maintained with the oral rehydration solution effective.
• The crossover design allowed for direct comparison between treatments in the same participants.
