Why does the human body need water to survive?

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.

  • Why water is so important to life?

    Water is the solvent that transports many essential molecules and other particles around the body. These include nutrients and waste products from the body's metabolic processes. Particles such as some ions and molecules need to be able to move around biological organisms.
  • Why do we need the food?

    A food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.

    To stay healthy, you need to continually replenish your fluid supply. Experts recommend drinking approximately two quarts (64 ounces or about eight glasses) of water each day.

    While water intoxication is rare, it can happen if you drink too much water too quickly. Drinking a gallon of water is safe if you spread it out throughout the day, but if you consume it in less than an hour, you risk getting water intoxication, which can be deadly.
