The water you're drinking today is ancient—some of it has been around for over 4 billion years, even before the Earth formed.

Less than 1% of the Earth's water is fresh and accessible for human use. The rest is either saline or locked in glaciers, making fresh water precious commodity.

Your brain is 75% water. Even slight dehydration can impair cognitive functions and mood, affecting your overall performance.

Some research suggests that water has a “memory” and can retain the energetic imprint of substances it has been in contact with, even after those substances are removed.

Humans can survive for weeks without food but only about 3 days without water, highlighting its critical importance to life.
