How Dehydration Affects Focus and Attention in Older Adults

The study highlights the significant impact of dehydration on sustained attention in middle-to-older-aged adults, who are more vulnerable to dehydration due to age-related changes in thirst perception. While dehydration did not impair memory or problem-solving, it made tasks requiring prolonged focus much harder. The findings emphasize the importance of staying hydrated to maintain mental sharpness, particularly for older adults.
