With brand-name water bottle fads and gallon-a-day water challenges trending on TikTok, hydration is in, and that’s good news for health. The average human body is more than 60% water. Water makes up almost two-thirds of your brain and heart, 83% of your lungs, 64% of your skin, and even 31% of your bones. It’s involved in almost every process that keeps you alive. So if you’ve hopped on the water-drinking bandwagon, you’re doing yourself a big solid.
“Water is essential for your body’s survival,” says Crystal Scott, registered dietitian-nutritionist with Top Nutrition Coaching. “It helps regulate your temperature, transports nutrients, removes waste, lubricates your joints and tissues, and it also plays a crucial role in maintaining the delicate balance of electrolytes and fluids in your body.”
