“Hydration is essential for cognitive performance. Even mild dehydration can impair focus and memory. Aim to drink water regularly throughout the day, especially during mentally demanding tasks.”
Hydration isn’t just about staying physically healthy—it’s critical for mental performance too. Research shows that even mild dehydration, as little as 1-2%, can impair cognitive functions like concentration, memory, and alertness. Your brain is made up of about 75% water, so staying hydrated helps maintain its function. To keep your mind sharp throughout the day, drink water regularly—especially before and during mentally demanding tasks. Carry a reusable water bottle, set reminders if needed, and aim for around 8 glasses a day or more, depending on your activity level.
