5 Amazing Facts about H2O
Water covers over 70% of the earth, but our bodies are made up of only
about 60% water! That’s right, we’re mostly water! Amazing, isn’t it?
It’s no wonder water has so many benefits, including flushing out toxins,
healing wounds and even cooling down your body temperature.
The following five facts about water will leave you in awe at this amazing
a substance that we just can’t live without.
1) Water makes up 70% of us
Water is all around us, so it’s easy to take it for granted—but that
would be a mistake. Our bodies are 70% water and our brains are
even more. Water makes up 90% of our blood, 70% of our muscles,
and 60% of our lungs. We can survive only 3 days without water
(and no more than 5 hours without it in our bodies), making life on
Earth possible for humans and other species alike. As your body
loses 1-2 liters of water per day through normal bodily functions,
you should replenish that amount to avoid dehydration; drinking
plenty of liquids every day will help keep you hydrated. Staying
hydrated helps prevent headaches and improves your mental
focus so be sure to drink enough!
2) The human body is 90% water
Most of us know that water is a key element in basic human survival.
It’s easy to forget, though, just how vital H20 is in our daily lives.
The fact that humans are essentially 90% water—and that we need
to consume at least 1.9 liters per day for optimum health—gives
new meaning to things like drinking your eight glasses of water a
day or flushing out your body with an IV after a long night of partying
(thanks, Lady Gaga). But humans aren’t alone in their love for water:
all life on Earth needs it to survive!
3) It’s our most abundant substance on Earth
Approximately 70% of Earth’s surface is covered by water. Water also
fills nearly 75% of our planet’s crust. We can live without it for only a
few days: Humans can survive without food for several weeks, but we
cannot survive more than a few days without water. We use more than
half of all available freshwater: In 2010, almost 4 billion people lacked
access to clean drinking water, and an estimated 2.6 billion people lacked
access to adequate sanitation services (World Health Organization).
That means that one in six people on Earth don’t have access to safe
drinking water and one in three people don’t have access to adequate

Water, water everywhere—and all of it different. What we don’t realize
is how much difference there can be among seemingly identical puddles
of water or snowflakes or droplets. The water that falls from above
varies in pH, mineral concentration, temperature, and electric charge.
It’s not just rainy vs. snowy places that provide a drastic difference
in water composition—even nearby sources (like groundwater springs)
will produce unique results. All of these tiny differences add up to one
big point: Not all waters are created equal. A rich source like Glacier
Bay® Bottled Water isn’t only high-quality and delicious—it’s highly
5) The weight of our planet is made up of water
The average weight of our planet is 60.07% water, meaning almost
two-thirds of Earth’s mass is submerged in oceans and rivers. It
would be a pretty small ball if it weren’t for so much water!
Check out our diagram to see how much H20 makes up each part
of Earth. The deepest part of the ocean is deeper than Mount Everest:
As deep as people will go into oceans, it seems like there’s always
a place that’s even deeper. There are underwater trenches that are
deeper than Mount Everest—but fortunately, you don’t have to
worry about falling down them (at least not in real life)! The average
ocean depth is 6.8 miles while Mount Everest measures 8.85 miles
