Hydrate to Think Faster

Here's the deal: even mild dehydration—just 1–2%—can mess with your memory, focus, and reaction time. Your brain runs better when it's properly hydrated.

Start your day with 16oz of water right when you wake up. Toss in a pinch of sea salt and a squeeze of lemon for electrolytes. Then set three reminders throughout the day to drink 8oz every couple of hours. If your urine's dark yellow, that's a sign you need more electrolytes, not just more water. (1/3)
