How much water should you drink each day? It’s a simple question with no easy answer.

Studies have produced varying recommendations over the years. But your individual water needs depend on many factors, including your health, how active you are and where you live.

No single formula fits everyone. But knowing more about your body’s need for fluids will help you estimate how much water to drink each day.

Health benefits of water

Water is your body’s principal chemical component and makes up about 60 percent of your body weight. Your body depends on water to survive.

Every cell, tissue and organ in your body needs water to work properly. For example, water:

• Gets rid of wastes through urination, perspiration and bowel movements
• Keeps your temperature normal
• Lubricates and cushions joints
• Protects sensitive tissues

Lack of water can lead to dehydration — a condition that occurs when you don’t have enough water in your body to carry out normal functions. Even mild dehydration can drain your energy and make you tired.
