A closer look
If you're feeling incredibly stupid by mid-afternoon, drink a glass of water. Your brain is a greedy sponge made of 73% water. Losing just 2% of your body's hydration forces brain cells to literally lose volume and pull away from the skull. This microscopic shrinkage disrupts neural signaling, utterly sabotaging your attention span, memory, and mood. You're not inherently dumb; your brain is just turning into a useless raisin.
