The brainâ€”and the rest of the bodyâ€”needs plenty of water to work at its peak levels.
Recent research by scientists studying the brain tells us what our grandmothers have always known: the body needs plenty of water to stay in good working order. When you study at home, have a pitcher of water at hand. At school, ask permission to have a bottle of water at your desk. The rule of thumb is that we should drink 6â€“8 glasses a day (about 48â€“64 oz., or somewhere between 1.5 and 2 litres).
Soda pop is not an approved substitutes for water. The sugar content in these drinks puts you on a roller-coaster of sugar highs and lows, and it does nothing to help your bodyâ€”including your brainâ€”work better. Fruit juice? Energy drinks? No. Stick with water.
