Most of the human body is water, with an average of roughly 65%. The amount of water in the body can change slightly with age, sex, and hydration levels.
Water is essential to the human body, making up about 65% of our total body weight. It plays a crucial role in nearly every bodily function. Water helps regulate body temperature, supports digestion by breaking down food, and transports nutrients and oxygen to cells. It also flushes out toxins through urine, lubricates joints, and acts as a shock absorber for the brain and spinal cord.
Proper hydration is vital for maintaining energy levels, cognitive function, and overall health. Without enough water, our bodies can't perform optimally, leading to dehydration and various health issues.
What are the health benefits of water?
Water is your body's principal chemical component and makes up about 50% to 70% 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.
