Dehydration Impairs Attention in Middle-Aged Adults

Mild dehydration can impair sustained attention in middle-aged and older adults, though it doesn't affect other cognitive functions. The study involved 78 adults, ages 47 to 70, and assessed their hydration levels and cognitive performance. Results showed that dehydration, common during typical daily activities, reduced attention span over 14 minutes. The findings highlight the need for regular hydration to maintain cognitive function in older adults.
