Since your brain consists mostly of water, drinking high-quality water helps you think and concentrate better and helps you to be more alert. As an added bonus, your energy levels are also boosted!
Water makes up about 60% of your body. Drinking enough H2O maintains your body’s fluid balance, which helps with nutrient transportation, temperature regulation, digestion, and more.
Water strengthens your immune system in two ways: First, it carries oxygen to your body's cells, which results in properly functioning systems. And secondly, it flushes harmful toxins from your body.
