Water is life. Literally. Life as we know it currently is improbable without liquid water. All life on Earth requires water to one degree or another. Water is so integral to life that astronomers look for liquid water as a sign of potential habitats for extraterrestrial life. A human being can die as quickly as 24 hours from lack of water.
Assuming perfect conditions, you might live up to 3-4 days without water to sustain you. You can go 30-40 days without food but water is more integral to our physiology. All of the chemical processes in your body require water to either carry out or facilitate. When you’re dehydrated, your blood changes from a thick red kool-aid into something closer to jello. As the blood thickens, it becomes increasingly more difficult for your heart to push that thicker fluid around your body.
Another property of water is its ability to incorporate chemical substances into its own makeup. If you have ever added a powdered mix to your water, then you have experienced that property first hand. Your body also incorporates a lot of chemicals into your body’s water. That balance of chemicals and water is necessary to carry out key biological functions like moving nutrients across the cell wall or from the blood vessels into the cells themselves. Your brain needs water to facilitate the transmissions of electrical impulses throughout the brain and nervous system.
Most of us feel we drink enough on a daily basis to keep hydrated, but the things we drink often dehydrate us instead of hydrate. Coffee, tea, soda and energy drinks often contain caffeine. Caffeine is a diuretic. What that means is that those drinks encourage the body to eliminate water from the body. Sports drinks can have a similar effect as they contain electrolytes, and by drinking too much of the sports drinks, this can cause an imbalance in the chemical composition of your body. For every sports drink you have, you need an equal amount of straight water.
When you get enough water in your diet, some very positive things can happen:
Your body needs water to produce the sugars your body uses for fuel. When you are dehydrated, the body has trouble synthesizing these sugars and you feel tired. When you get enough water, your body’s power-plant can run at full steam and you will feel energized.
Your digestive processes need water to operate at full effectiveness just like the rest of your body. Water lubricates the bowels and facilitates the transfer of nutrients from the bowels to the bloodstream. Water also keeps the waste products moving on down the line. Less water means more waste gets slowed down inside the colon and small intestine. Digestive disorders often have their causes traced back to chronic dehydration.
