TED-Ed: What would happen if you didn't drink water? - Mia Nacamulli

Water is essential for human health, making up a significant portion of our bodies and playing key roles in cushioning joints, regulating temperature, and nourishing the brain. Daily water loss through sweat, urine, and breathing necessitates regular intake to maintain balance and avoid dehydration or overhydration, both of which can have serious health effects. The recommended daily water intake varies based on factors like weight and environment, with food and beverages also contributing to hydration. Proper hydration can lower the risk of stroke, diabetes, and certain cancers.
