How Much Water Is In The Human Body?

water in the body

Water is in nearly everything. All living things — big and small, human and nonhuman, plant and animal — need water to survive.

Have you ever wondered how much of your body is water? It’s more than you may think. The body changes over time, and you lose water content with age — but the average adult is composed of about 60% water. It’s the primary component of cells, tissues, and organs, and is involved in almost every important body function and system.

Organs like your heart, lungs, kidneys, liver, and brain all contain significant volumes of water, ranging from 64-83%. Even your bones, which have comparatively lower water content, are still about 31% water.

Infants’ and young children’s bodies contain even more water — newborns have about 75% water in their bodies at birth. In comparison, older adults lose water during the aging process, maintaining about only 50% water content.

But it’s not just us! Water can be found inside everything from your family pet to the trees out back to the fruits and vegetables in your fridge.

It’s easy to forget to drink as much water as you should when you’re on-the-go all the time, but as you can see, water is necessary to the survival of just about every living organism.

So, take steps every day to make sure you pay attention to your daily water intake and drink plenty of water.
