21 Amazing Importance of Water (H2O) to the Body


Around 60 percent of the body is made up of water (H2O), and around 71 percent of the planet’s surface is covered by water. Keeping hydrated is crucial for health and well-being, but many people do not consume enough fluids each day. Perhaps it is the ubiquitous nature of water that means drinking enough each day is not at the top of many people’s lists of priorities.

Your body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it’s important to rehydrate by drinking fluids and eating foods that contain water. The amount of water you need depends on a variety of factors, including the climate you live in, how physically active you are, and whether you’re experiencing an illness or have any other health problems.
