The Health Benefits of Water
Water makes up about 50% to 70% of the human body weight, and every cell, tissue, and organ inside our bodies needs water to function properly. Here are some benefits to it:
- Keeps our temperature normal
- Gets rid of waste through urination, perspiration, and bowel movements
- Lubricates and cushions joints
- Protects sensitive tissues
Okay, so water is good, but what happens when we don’t drink enough of it? Well, it can lead to dehydration or in other words, the condition of our bodies where the above functions are less likely to happen. Keep in mind that even mild dehydration can drain energy and make people feel tired.
How Much Water Is Enough Water & Debunking the Myth
The National Academy of Medicine recommends that an adequate daily fluid intake is about 15.5 cups (3.7 liters) of fluids for men and 11.5 cups (2.7 liters) for women.
However, Aaron Carroll, MD who published an article in The New York Times is debunking the eight-cups-a-day myth. He points out that most people get enough hydration from foods and beverages and there is no scientific need for 64 ounces of pure water in a day.
“When you’re thirsty, you’re way far away from dehydration,” he says. “Just drink when you’re thirsty.”
Can Drinking too Much Water Be a Problem?
Yes, but it is very difficult to drink too much water by accident. However, it can still happen, usually as a result of overhydrating during sporting events or intense training. This is called hyponatremia and it means that your kidneys can’t get rid of the excess water, the sodium content of your blood becomes diluted, and overall, it can be life-threatening.
Keep in mind that physically active people and pregnant women, for example, may need to drink more water than the average person. However, sticking close to what the National Academy of Medicine recommends should be ideal for the average person.
